The data cover more than 12,101 women-years of exposure up to years of use, mainly in the contraception studies (11,761 women-years). The frequencies of reported adverse drug reactions represent crude incidences.The most common adverse reactions (>=10% users) are alterations of menstrual bleeding patterns [including unscheduled uterine bleeding (31.9%), decreased uterine bleeding (23.4%), increased scheduled uterine bleeding (11.9%), and female genital tract bleeding (3.5%)], abdominal/pelvic pain (22.6%), amenorrhea (18.4%), headache/migraine (16.3%), genital discharge (14.9%), and vulvovaginitis (10.5%).

By the end of Year of use, amenorrhea and infrequent bleeding are experienced by 28% and 26% of users, respectively; irregular bleeding occurs in 12%, frequent bleeding in 8%, and prolonged bleeding in 2% of users. In this study, 6% of women reported the adverse event of weight gain; it is unknown if the weight gain was caused by Mirena.. 6.2 Postmarketing Experience. Adverse Reactions from Postmarketing Spontaneous Reports The following adverse reactions have been identified during post approval use of Mirena. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.oArterial thrombotic and venous thromboembolic events, including cases of pulmonary embolism, deep vein thrombosis and stroke oDevice breakageoHypersensitivity (including rash, urticaria and angioedema)oIncreased blood pressure. oArterial thrombotic and venous thromboembolic events, including cases of pulmonary embolism, deep vein thrombosis and stroke oDevice breakage. oHypersensitivity (including rash, urticaria and angioedema). oIncreased blood pressure. Reported Adverse Reactions from Postmarketing Studies Assessment of Perforation and Expulsion of Intrauterine Devices (APEX IUD) Study APEX IUD was large US retrospective cohort study to assess the impact of breastfeeding and timing of postpartum IUD insertion on uterine perforation and IUD expulsion. The analyses included total of 326,658 insertions, 30% (97,824 insertions) of which were performed in women with delivery in the previous 12 months. For insertions performed in women who had delivered <= 52 weeks before IUD insertion, the majority of postpartum insertions, 57.3% (56,047 insertions) occurred between and 14 weeks postpartum. Breastfeeding data were available in 94,817 insertions performed in women 52 weeks or less after delivery. The study results indicated that the risk of uterine perforation was highest in women with IUD insertion <= weeks postpartum. Immediate postpartum insertion (0-3 days) findings are limited due to the relatively small number of insertions occurring within this time interval. Women who were breastfeeding at the time of insertion were at 33% higher risk of perforation (adjusted hazard ratio [HR]=1.33, 95% confidence interval [CI]: 1.07-1.64) compared to women who were not breastfeeding at the time of insertion. Progressively lower risk of uterine perforation was observed in postpartum time windows beyond weeks, in both breastfeeding and not breastfeeding women. Table presents the uterine perforation rates for LNG IUS stratified by breastfeeding status and postpartum interval.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility [See Warnings and Precautions (5.9)].

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action The local mechanism by which continuously released LNG contributes to the contraceptive effectiveness of Mirena has not been conclusively demonstrated. Studies of Mirena and similar LNG IUS prototypes have suggested several mechanisms that prevent pregnancy: thickening of cervical mucus preventing passage of sperm into the uterus, inhibition of sperm capacitation or survival, and alteration of the endometrium. 12.2 Pharmacodynamics Mirena has mainly local progestogenic effects in the uterine cavity. The local concentrations of LNG lead to morphological changes including stromal pseudodecidualization, glandular atrophy, leukocytic infiltration and decrease in glandular and stromal mitoses. Ovulation is inhibited in some women using Mirena. In 1-year study, approximately 45% of menstrual cycles were ovulatory, and in another study after years, 75% of cycles were ovulatory.. 12.3 Pharmacokinetics Absorption. Low doses of LNG are administered into the uterine cavity with the Mirena intrauterine delivery system. The initial release rate is approximately 20 mcg/day over the first months tested (day to day 90). It is reduced to approximately 18 mcg/day after year, 10 mcg/day after years, and mcg/day after years. stable serum concentration, without peaks and troughs, of LNG of 150-200 pg/mL occurs after the first few weeks following insertion of Mirena. LNG concentrations after long-term use of 1, 2, 5, and years were 180+-66 pg/mL, 192+-140 pg/mL, 159+-59 pg/mL, and 107+-40 pg/mL, respectively. Distribution. The apparent volume of distribution of LNG is reported to be approximately 1.8 L/kg. It is about 97.5 to 99% protein-bound, principally to sex hormone binding globulin (SHBG) and, to lesser extent, serum albumin. Metabolism. Following absorption, LNG is conjugated at the 17-OH position to form sulfate conjugates and, to lesser extent, glucuronide conjugates in serum. Significant amounts of conjugated and unconjugated 3, 5- tetrahydrolevonorgestrel are also present in serum, along with much smaller amounts of 3, 5-tetrahydrolevonorgestrel and 16-hydroxylevonorgestrel. LNG and its phase metabolites are excreted primarily as glucuronide conjugates. Metabolic clearance rates may differ among individuals by several-fold, and this may account in part for wide individual variations in LNG concentrations seen in individuals using LNG-containing contraceptive products. In vitro studies have demonstrated that oxidative metabolism of LNG is catalyzed by CYP enzymes, especially CYP3A4.. Excretion. About 45% of LNG and its metabolites are excreted in the urine and about 32% are excreted in feces, mostly as glucuronide conjugates. The elimination half-life of LNG after daily oral doses is approximately 17 hours. Specific Populations. Pediatric: Safety and efficacy of Mirena have been established in women of reproductive age. Use of this product before menarche is not indicated. Geriatric: Mirena has not been studied in women over age 65 and is not currently approved for use in this population. Race: No studies have evaluated the effect of race on the pharmacokinetics of Mirena. Hepatic Impairment: No studies were conducted to evaluate the effect of hepatic disease on the disposition of Mirena. Renal Impairment: No formal studies were conducted to evaluate the effect of renal disease on the disposition of Mirena. Drug-Drug Interactions. No drug-drug interaction studies were conducted with Mirena [see Drug Interactions 7)].

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES 14.1 Clinical Trials on Contraception. The safety and effectiveness of Mirena was studied in two clinical trials in Finland and Sweden. In these trials, 1,169 women 18 to 35 years of age at enrollment used Mirena for up to years, for total of 45,000 women-months of exposure. Of these, 5.6% (66) were nulliparous women. Subjects had previously been pregnant, had no history of ectopic pregnancy, had no history of pelvic inflammatory disease over the preceding 12 months, were predominantly White, and over 70% of the subjects had previously used IUDs (intrauterine devices). The reported 12-month pregnancy rates were less than or equal to 0.2 per 100 women (0.2%) and the cumulative 5-year pregnancy rate was approximately 0.7 per 100 women (0.7%). The contraceptive efficacy of Mirena during extended use beyond years was studied in the Mirena Extension Trial (NCT02985541), multi-center, open-label, uncontrolled study conducted in the United States. The trial enrolled women 18 to 35 years of age who had been using Mirena for not less than 4.5 years and not more than years at enrollment. The population consisted of 362 women using Mirena. Of these 47.2% were nulliparous. The women were predominantly White (75.4%); 14.1% of the women were Black/African American, and 2.5% were Asian; 11.3 were Hispanic. The weight range was 38.5-163.5 kg (mean weight: 75.6 kg) and mean BMI was 27.9 kg/m2 (range: 15.4-57.7 kg/m2). The pregnancy rate calculated as the Pearl Index (PI) was the primary efficacy endpoint used to assess contraceptive efficacy. The PI was based on 28-day equivalent exposure cycles; evaluable cycles excluded those in which back-up contraception was used unless pregnancy occurred in that cycle. The PI for the 6th year of use based on the pregnancy that occurred during Year and within days after Mirena removal or expulsion and 3,722 evaluable cycles was 0.35 with 95% upper confidence limit of 1.95, and the PI for the 7th year of use based on the pregnancy that occurred during Year and within days after Mirena removal or expulsion and 2,912 evaluable cycles was 0.45 with 95% upper confidence limit of 2.49. The cumulative 2-year pregnancy rate for Years and was estimated by the Kaplan-Meier method. Based on pregnancies (1 in Year and in Year 7) and 7,269 exposure cycles, the cumulative pregnancy rate at the end of the 2-year period of extended use (Years and 7) was 0.71% with 95% upper confidence limit of 2.84%.. 14.2 Clinical Trial on Heavy Menstrual Bleeding. The efficacy of Mirena in the treatment of heavy menstrual bleeding was studied in randomized, open-label, active-control, parallel-group trial comparing Mirena (n=79) to an approved therapy, medroxyprogesterone acetate (MPA) (n=81), over cycles. The subjects included reproductive-aged women in good health, with no contraindications to the drug products and with confirmed heavy menstrual bleeding (>= 80 mL menstrual blood loss [MBL]) determined using the alkaline hematin method. Excluded were women with organic or systemic conditions that may cause heavy uterine bleeding (except small fibroids, with total volume not 5 mL). Treatment with Mirena showed statistically significantly greater reduction in MBL (see Figure 12) and statistically significantly greater number of subjects with successful treatment (see Figure 13). Successful treatment was defined as proportion of subjects with (1) end-of-study MBL 80 mL and (2) >= 50% decrease in MBL from baseline to end-of-study.Figure 12. Median Menstrual Blood Loss (MBL) by Time and TreatmentFigure 13. Proportion of Subjects with Successful Treatment. MBL Figure. fig 13Proportion of Subjects with Successful Treatment.

DESCRIPTION SECTION.

11 DESCRIPTION Mirena (levonorgestrel-releasing intrauterine system) contains 52 mg of LNG, progestin, and is intended to provide an initial release rate of approximately 20 mcg/day of LNG.Levonorgestrel USP, (-)-13-Ethyl-17-hydroxy-18,19-dinor-17-pregn-4-en-20-yn-3-one, the active ingredient in Mirena, has molecular weight of 312.4, molecular formula of C21H28O2, and the following structural formula:. 11.1 Mirena. Mirena consists of T-shaped polyethylene frame (T-body) with steroid reservoir (hormone elastomer core) around the vertical stem. The white T-body has loop at one end of the vertical stem and two horizontal arms at the other end. The reservoir consists of white or almost white cylinder, made of mixture of LNG and silicone (polydimethylsiloxane), containing total of 52 mg LNG. The reservoir is covered by semi-opaque silicone membrane, composed of polydimethylsiloxane and colloidal silica. The T-body is 32 mm in both the horizontal and vertical directions. The polyethylene of the T-body is compounded with barium sulfate, which makes it radiopaque. monofilament brown polyethylene removal thread is attached to loop at the end of the vertical stem of the T-body. The polyethylene of the removal thread contains iron oxide as colorant (see Figure 10).The components of Mirena, including its packaging, are not manufactured using natural rubber latex.Figure 10. Mirena. Mirena IUD. 11.2 Inserter Mirena is packaged sterile within an inserter. The inserter (Figure 11), which is used for insertion of Mirena into the uterine cavity, consists of symmetric two-sided body and slider that are integrated with flange, lock, pre-bent insertion tube and plunger. The outer diameter of the insertion tube is 4.4 mm. The vertical stem of Mirena is loaded in the insertion tube at the tip of the inserter. The arms are pre-aligned in the horizontal position. The removal threads are contained within the insertion tube and handle. Once Mirena has been placed, the inserter is discarded.Figure 11. Diagram of Inserter. Mirena Inserter. Chemical Structure.

LACTATION SECTION.

8.2 Lactation Risk Summary Published studies report the presence of LNG in human milk. Small amounts of progestins (approximately 0.1% of the total maternal doses) were detected in the breast milk of nursing mothers who used Mirena, resulting in exposure of LNG to the breastfed infants. There are no reports of adverse effects in breastfed infants with maternal use of progestin-only contraceptives. Isolated cases of decreased milk production have been reported with Mirena. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for Mirena and any potential adverse effects on the breastfed child from Mirena or from the underlying maternal condition.

MECHANISM OF ACTION SECTION.

12.1 Mechanism of Action The local mechanism by which continuously released LNG contributes to the contraceptive effectiveness of Mirena has not been conclusively demonstrated. Studies of Mirena and similar LNG IUS prototypes have suggested several mechanisms that prevent pregnancy: thickening of cervical mucus preventing passage of sperm into the uterus, inhibition of sperm capacitation or survival, and alteration of the endometrium.

PEDIATRIC USE SECTION.

8.4 Pediatric Use Safety and efficacy of Mirena have been established in women of reproductive age. Efficacy is expected to be the same for postpubertal females under the age of 18 as for users 18 years and older. Use of this product before menarche is not indicated.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics Mirena has mainly local progestogenic effects in the uterine cavity. The local concentrations of LNG lead to morphological changes including stromal pseudodecidualization, glandular atrophy, leukocytic infiltration and decrease in glandular and stromal mitoses. Ovulation is inhibited in some women using Mirena. In 1-year study, approximately 45% of menstrual cycles were ovulatory, and in another study after years, 75% of cycles were ovulatory.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics Absorption. Low doses of LNG are administered into the uterine cavity with the Mirena intrauterine delivery system. The initial release rate is approximately 20 mcg/day over the first months tested (day to day 90). It is reduced to approximately 18 mcg/day after year, 10 mcg/day after years, and mcg/day after years. stable serum concentration, without peaks and troughs, of LNG of 150-200 pg/mL occurs after the first few weeks following insertion of Mirena. LNG concentrations after long-term use of 1, 2, 5, and years were 180+-66 pg/mL, 192+-140 pg/mL, 159+-59 pg/mL, and 107+-40 pg/mL, respectively. Distribution. The apparent volume of distribution of LNG is reported to be approximately 1.8 L/kg. It is about 97.5 to 99% protein-bound, principally to sex hormone binding globulin (SHBG) and, to lesser extent, serum albumin. Metabolism. Following absorption, LNG is conjugated at the 17-OH position to form sulfate conjugates and, to lesser extent, glucuronide conjugates in serum. Significant amounts of conjugated and unconjugated 3, 5- tetrahydrolevonorgestrel are also present in serum, along with much smaller amounts of 3, 5-tetrahydrolevonorgestrel and 16-hydroxylevonorgestrel. LNG and its phase metabolites are excreted primarily as glucuronide conjugates. Metabolic clearance rates may differ among individuals by several-fold, and this may account in part for wide individual variations in LNG concentrations seen in individuals using LNG-containing contraceptive products. In vitro studies have demonstrated that oxidative metabolism of LNG is catalyzed by CYP enzymes, especially CYP3A4.. Excretion. About 45% of LNG and its metabolites are excreted in the urine and about 32% are excreted in feces, mostly as glucuronide conjugates. The elimination half-life of LNG after daily oral doses is approximately 17 hours. Specific Populations. Pediatric: Safety and efficacy of Mirena have been established in women of reproductive age. Use of this product before menarche is not indicated. Geriatric: Mirena has not been studied in women over age 65 and is not currently approved for use in this population. Race: No studies have evaluated the effect of race on the pharmacokinetics of Mirena. Hepatic Impairment: No studies were conducted to evaluate the effect of hepatic disease on the disposition of Mirena. Renal Impairment: No formal studies were conducted to evaluate the effect of renal disease on the disposition of Mirena. Drug-Drug Interactions. No drug-drug interaction studies were conducted with Mirena [see Drug Interactions 7)].

PREGNANCY SECTION.

8.1 Pregnancy Risk Summary The use of Mirena is contraindicated in pregnancy or with suspected pregnancy and Mirena may cause adverse pregnancy outcomes [see Contraindications (4), Warnings and Precautions (5.1, 5.2)]. If woman becomes pregnant with Mirena in place, the likelihood of ectopic pregnancy is increased and there is an increased risk of miscarriage, sepsis, premature labor, and premature delivery. Remove Mirena, if possible, if pregnancy occurs in woman using Mirena. If Mirena cannot be removed, follow the pregnancy closely [see Warnings and Precautions (5.1, 5.2)]. There have been isolated cases of virilization of the external genitalia of the female fetus following local exposure to LNG during pregnancy with an LNG IUS in place.

RISKS.

Risk Summary The use of Mirena is contraindicated in pregnancy or with suspected pregnancy and Mirena may cause adverse pregnancy outcomes [see Contraindications (4), Warnings and Precautions (5.1, 5.2)]. If woman becomes pregnant with Mirena in place, the likelihood of ectopic pregnancy is increased and there is an increased risk of miscarriage, sepsis, premature labor, and premature delivery. Remove Mirena, if possible, if pregnancy occurs in woman using Mirena. If Mirena cannot be removed, follow the pregnancy closely [see Warnings and Precautions (5.1, 5.2)]. There have been isolated cases of virilization of the external genitalia of the female fetus following local exposure to LNG during pregnancy with an LNG IUS in place.

SPL PATIENT PACKAGE INSERT SECTION.

Patient Package Insert. Patient InformationMIRENA(R) (mur-a-nah) (levonorgestrel-releasing intrauterine system)Read this Patient Information carefully before you decide if MIRENA is right for you. This information does not take the place of talking with your gynecologist or other healthcare provider who specializes in womens health. If you have any questions about MIRENA, ask your healthcare provider. You should also learn about other birth control methods to choose the one that is best for you. MIRENA does not protect against HIV infection (AIDS) and other sexually transmitted infections (STIs).What is MIRENAoMIRENA is hormone-releasing system placed in your uterus by your healthcare provider to prevent pregnancy for up to years. oMIRENA can also be used to decrease menstrual blood loss for up to years in women who have heavy menstrual flow and who also want to use birth control method that is placed in the uterus to prevent pregnancy. oMIRENA can be removed by your healthcare provider at any time.oMIRENA can be used whether or not you have given birth to child. MIRENA is small flexible plastic T-shaped system that slowly releases progestin hormone called levonorgestrel (LNG) that is often used in birth control pills. Because MIRENA releases LNG into your uterus, only small amounts of the hormone enter your blood. MIRENA does not contain estrogen.Two thin threads are attached to the stem (lower end) of MIRENA. The threads are the only part of MIRENA you can feel when MIRENA is in your uterus; however, unlike tampon string, the threads do not extend outside your body.MIRENA is smalland flexibleWhat if need birth control for more than years MIRENA must be removed after years. Your healthcare provider can place new MIRENA during the same office visit if you choose to continue using MIRENA. What if need treatment for heavy menstrual flow for more than years For continued treatment of heavy menstrual flow after years, your healthcare provider can remove MIRENA and place new MIRENA during the same office visit.What if want to stop using MIRENAMIRENA is intended for use up to years, but you can stop using MIRENA at any time by asking your healthcare provider to remove it. You could become pregnant as soon as MIRENA is removed, so you should use another method of birth control if you do not want to become pregnant. Talk to your healthcare provider about the best birth control methods for you, because your new method may need to be started days before MIRENA is removed to prevent pregnancy.What if change my mind about birth control and want to become pregnant in less than years Your healthcare provider can remove MIRENA at any time. You may become pregnant as soon as MIRENA is removed. About out of 10 women who want to become pregnant will become pregnant sometime in the first year after MIRENA is removed.How does MIRENA workMIRENA may work in several ways including thickening cervical mucus, inhibiting sperm movement, reducing sperm survival, and thinning the lining of your uterus. It is not known exactly how these actions work together to prevent pregnancy. MIRENA can cause your menstrual bleeding to be less by thinning the lining of the uterus. How well does MIRENA work for contraception The following chart shows the chance of getting pregnant for women who use different methods of birth control. Each box on the chart contains list of birth control methods that are similar in effectiveness. The most effective methods are at the top of the chart. The box on the bottom of the chart shows the chance of getting pregnant for women who do not use birth control and are trying to get pregnant.MIRENA, an intrauterine device (IUD), also known as an intrauterine system (IUS), is in the box at the top of the chart.How well does MIRENA work for heavy menstrual bleeding In the clinical trial performed in women with heavy menstrual bleeding and treated with MIRENA, almost out of 10 were treated successfully and their blood loss was reduced by more than half.Who might use MIRENA You might choose MIRENA if you: owant long-term birth control that provides low chance of getting pregnant (less than in 100) owant birth control that works continuously for up to years owant birth control that is reversible owant birth control method that you do not need to take daily owant treatment for heavy periods up to years and are willing to use birth control method that is placed in the uterusowant birth control that does not contain estrogenDo not use MIRENA if you:oare or might be pregnant; MIRENA cannot be used as an emergency contraceptive ohave serious pelvic infection called pelvic inflammatory disease (PID) or have had PID in the past unless you have had normal pregnancy after the infection went awayohave an untreated genital infection nowohave had serious pelvic infection in the past months after pregnancy ocan get infections easily. For example, if you:ohave multiple sexual partners or your partner has multiple sexual partnersohave problems with your immune systemouse or abuse intravenous drugsohave or suspect you might have cancer of the uterus or cervix ohave bleeding from the vagina that has not been explained ohave liver disease or liver tumor ohave breast cancer or any other cancer that is sensitive to progestin (a female hormone), now or in the past ohave an intrauterine device in your uterus already ohave condition of the uterus that changes the shape of the uterine cavity, such as large fibroid tumors oare allergic to levonorgestrel, silicone, polyethylene, silica, barium sulfate or iron oxideBefore having MIRENA placed, tell your healthcare provider about all of your medical conditions including if you: ohave any of the conditions listed aboveohave had heart attackohave had strokeowere born with heart disease or have problems with your heart valves ohave problems with blood clotting or take medicine to reduce clotting ohave high blood pressureorecently had baby or are breastfeeding ohave severe headaches or migraine headaches ohave AIDS, HIV, or any other sexually transmitted infectionTell your healthcare provider about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.How is MIRENA placed MIRENA is placed by your healthcare provider during an in-office visit or immediately after giving birth.First, your healthcare provider will examine your pelvis to find the exact position of your uterus. Your healthcare provider will then clean your vagina and cervix with an antiseptic solution and slide slim plastic tube containing MIRENA through the cervix into your uterus. Your healthcare provider will then remove the plastic tube and leave MIRENA in your uterus. Your healthcare provider will cut the threads to the right length.You may experience pain, bleeding or dizziness during and after placement. If your symptoms do not pass within 30 minutes after placement, MIRENA may not have been placed correctly. Your healthcare provider will examine you to see if MIRENA needs to be removed or replaced.Should check that MIRENA is in placeYes, you should check that MIRENA is in proper position by feeling the removal threads. It is good habit to do this time month. Your healthcare provider should teach you how to check that MIRENA is in place. First, wash your hands with soap and water. You can check by reaching up to the top of your vagina with clean fingers to feel the removal threads. Do not pull on the threads. If you feel more than just the threads or if you cannot feel the threads, MIRENA may not be in the right position and may not prevent pregnancy. Avoid intercourse or use non-hormonal back-up birth control (such as condoms or spermicide) and ask your healthcare provider to check that MIRENA is still in the right place. How soon after placement of MIRENA should return to my healthcare providerCall your healthcare provider if you have any questions or concerns (see When should call my healthcare provider). Otherwise, you should return to your healthcare provider for follow-up visit to weeks after MIRENA is placed to make sure that MIRENA is in the right position. Can use tampons or menstrual cups with MIRENAYes, tampons or menstrual cups may be used with MIRENA. Change tampons or menstrual cups with care to avoid pulling the threads of Mirena. If you think you may have pulled Mirena out of place, avoid intercourse or use non-hormonal back-up birth control (such as condoms or spermicide), and contact your healthcare provider.What if become pregnant while using MIRENA Call your healthcare provider right away if you think you may be pregnant. If possible, also do urine pregnancy test. If you get pregnant while using MIRENA, you may have an ectopic pregnancy. This means that the pregnancy is not in the uterus. Unusual vaginal bleeding or abdominal pain especially with missed periods may be sign of ectopic pregnancy. Ectopic pregnancy is medical emergency that often requires surgery. Ectopic pregnancy can cause internal bleeding, infertility, and even death. There are also risks if you get pregnant while using MIRENA and the pregnancy is in the uterus. Severe infection, miscarriage, premature delivery, and even death can occur with pregnancies that continue with an intrauterine device (IUD). Because of this, your healthcare provider may try to remove MIRENA, even though removing it may cause miscarriage. If MIRENA cannot be removed, talk with your healthcare provider about the benefits and risks of continuing the pregnancy and possible effects of the hormone on your unborn baby. If you continue your pregnancy, see your healthcare provider regularly. Call your healthcare provider right away if you get flu-like symptoms, fever, chills, cramping, pain, bleeding, vaginal discharge, or fluid leaking from your vagina. These may be signs of infection. How will MIRENA change my periods For the first to months, your period may become irregular and the number of bleeding days may increase. You may also have frequent spotting or light bleeding, and some women have heavy bleeding during this time. You may also have cramping during the first few weeks. After you have used MIRENA for while, the number of bleeding and spotting days is likely to lessen. For some women, periods will stop altogether. When Mirena is removed, your menstrual periods should return.In some women with heavy bleeding, the total blood loss per cycle progressively decreases with continued use. The number of spotting and bleeding days may initially increase but then typically decreases in the months that follow.Is it safe to breastfeed while using MIRENAYou may use MIRENA when you are breastfeeding. MIRENA is not likely to affect the quality or amount of your breast milk or the health of your nursing baby. However, isolated cases of decreased milk production have been reported. The risk of MIRENA going into the wall of the uterus (becoming embedded) or going through the wall of the uterus is increased if MIRENA is inserted while you are breastfeeding.Will MIRENA interfere with sexual intercourseYou and your partner should not feel MIRENA during intercourse. MIRENA is placed in the uterus, not in the vagina. Sometimes your partner may feel the threads. If this occurs, or if you or your partner experience pain during sex, talk with your healthcare provider.What are the possible side effects of MIRENA MIRENA can cause serious side effects including: oEctopic pregnancy and intrauterine pregnancy risks. There are risks if you become pregnant while using Mirena (see What if become pregnant while using Mirena).oLife-threatening infection. Life-threatening infection can occur within the first few days after MIRENA is placed. Call your healthcare provider immediately if you develop severe pain or fever shortly after MIRENA is placed. oPelvic inflammatory disease (PID). Some IUD users get serious pelvic infection called pelvic inflammatory disease. PID is usually sexually transmitted. You have higher chance of getting PID if you or your partner has sex with other partners. PID can cause serious problems such as infertility, ectopic pregnancy or pelvic pain that does not go away. PID is usually treated with antibiotics. More serious cases of PID may require surgery including removal of the uterus (hysterectomy). In rare cases, infections that start as PID can even cause death. Tell your healthcare provider right away if you have any of these signs of PID: long-lasting or heavy bleeding, unusual vaginal discharge, low abdominal (stomach area) pain, painful sex, chills, fever, genital lesions or sores. oPerforation. MIRENA may go into the wall of the uterus (become embedded) or go through the wall of the uterus. This is called perforation. If this occurs, MIRENA may no longer prevent pregnancy. If perforation occurs, MIRENA may move outside the uterus and can cause internal scarring, infection, or damage to other organs, and you may need surgery to have MIRENA removed. Excessive pain or vaginal bleeding during placement of MIRENA, pain or bleeding that gets worse after placement, or not being able to feel the threads may happen with perforation. The risk of perforation is increased if MIRENA is inserted while you are breastfeeding, or if you have recently given birth.oExpulsion. MIRENA may come out by itself. This is called expulsion. Excessive pain or vaginal bleeding during placement of MIRENA, pain or bleeding that gets worse after placement, or not being able to feel the threads may happen with expulsion. You may become pregnant if MIRENA comes out. If you think that MIRENA has come out, avoid intercourse or use non-hormonal back-up birth control (such as condoms or spermicide) and call your healthcare provider. The risk of expulsion is increased with insertion right after delivery or second-trimester abortion.Common side effects of Mirena include:oPain, bleeding or dizziness during and after placement. If these symptoms do not stop 30 minutes after placement, MIRENA may not have been placed correctly. Your healthcare provider will examine you to see if MIRENA needs to be removed or replaced.oChanges in bleeding. You may have bleeding and spotting between menstrual periods, especially during the first to months. Sometimes the bleeding is heavier than usual at first. However, the bleeding usually becomes lighter than usual and may be irregular. Call your healthcare provider if the bleeding remains heavier than usual or increases after it has been light for while.oMissed menstrual periods. About out of 10 women stop having periods after year of MIRENA use. If you have any concerns that you may be pregnant while using MIRENA, do urine pregnancy test and call your healthcare provider. If you do not have period for weeks during MIRENA use, call your healthcare provider. When MIRENA is removed, your menstrual periods should return.oCysts on the ovary. Some women using MIRENA develop painful cyst on the ovary. These cysts usually disappear on their own in to months. However, cysts can cause pain and sometimes cysts will need surgery. Other common side effects include:oabdominal or pelvic painoinflammation or infection of the outer part of your vagina (vulvovaginitis)oheadache or migraineovaginal dischargeThese are not all of the possible side effects with MIRENA. For more information, ask your healthcare provider. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. You may also report side effects to Bayer Healthcare Pharmaceuticals at 1-888-842-2937.After MIRENA has been placed, when should call my healthcare providerIf Mirena is accidentally removed and you had vaginal intercourse within the preceding week, you may be at risk of pregnancy, and you should talk to healthcare provider.Call your healthcare provider if you have any concerns about MIRENA. Be sure to call if you: othink you are pregnant ohave pelvic pain, abdominal pain or pain during sex ohave unusual vaginal discharge or genital sores ohave unexplained fever, flu-like symptoms or chills omight be exposed to sexually transmitted infections (STIs) oare concerned that Mirena may have been expelled (came out) ocannot feel MIRENAs threads odevelop very severe or migraine headaches ohave yellowing of the skin or whites of the eyes.

1.1 Contraception Mirena is indicated for prevention of pregnancy for up to years; replace after the end of the seventh year.

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary The use of Mirena is contraindicated in pregnancy or with suspected pregnancy and Mirena may cause adverse pregnancy outcomes [see Contraindications (4), Warnings and Precautions (5.1, 5.2)]. If woman becomes pregnant with Mirena in place, the likelihood of ectopic pregnancy is increased and there is an increased risk of miscarriage, sepsis, premature labor, and premature delivery. Remove Mirena, if possible, if pregnancy occurs in woman using Mirena. If Mirena cannot be removed, follow the pregnancy closely [see Warnings and Precautions (5.1, 5.2)]. There have been isolated cases of virilization of the external genitalia of the female fetus following local exposure to LNG during pregnancy with an LNG IUS in place. 8.2 Lactation Risk Summary Published studies report the presence of LNG in human milk. Small amounts of progestins (approximately 0.1% of the total maternal doses) were detected in the breast milk of nursing mothers who used Mirena, resulting in exposure of LNG to the breastfed infants. There are no reports of adverse effects in breastfed infants with maternal use of progestin-only contraceptives. Isolated cases of decreased milk production have been reported with Mirena. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for Mirena and any potential adverse effects on the breastfed child from Mirena or from the underlying maternal condition.. 8.3 Females and Males of Reproductive Potential Return to Fertility After Discontinuing Mirena In two studies, return to fertility was investigated in total of 229 women who desired pregnancy after study discontinuation and provided follow-up information. The probability to conceive within 12 months after removal of Mirena was approximately 80%.. 8.4 Pediatric Use Safety and efficacy of Mirena have been established in women of reproductive age. Efficacy is expected to be the same for postpubertal females under the age of 18 as for users 18 years and older. Use of this product before menarche is not indicated. 8.5 Geriatric Use Mirena has not been studied in women over age 65 and is not approved for use in this population.

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS oRemove Mirena if pregnancy occurs with Mirena in place. If pregnancy occurs, there is increased risk of ectopic pregnancy including loss of fertility, pregnancy loss, septic abortion (including septicemia, shock and death), and premature labor and delivery. (5.1, 5.2)oGroup streptococcal infection has been reported following insertion of LNG IUS; strict aseptic technique is essential during insertion. (5.3)oBefore using Mirena, consider the risks of PID. (5.4)oUterine perforation may occur and may reduce contraceptive effectiveness or require surgery. Risk is increased if inserted in lactating women and may be increased if inserted in women with fixed retroverted uteri or postpartum. (5.5)oPartial or complete expulsion may occur, which can be unnoticed, leading to loss of contraceptive efficacy. (5.6)oEvaluate persistent enlarged ovarian follicles or ovarian cysts. (5.7)oBleeding patterns become altered, may remain irregular and amenorrhea may ensue. (5.8). oRemove Mirena if pregnancy occurs with Mirena in place. If pregnancy occurs, there is increased risk of ectopic pregnancy including loss of fertility, pregnancy loss, septic abortion (including septicemia, shock and death), and premature labor and delivery. (5.1, 5.2). oGroup streptococcal infection has been reported following insertion of LNG IUS; strict aseptic technique is essential during insertion. (5.3). oBefore using Mirena, consider the risks of PID. (5.4). oUterine perforation may occur and may reduce contraceptive effectiveness or require surgery. Risk is increased if inserted in lactating women and may be increased if inserted in women with fixed retroverted uteri or postpartum. (5.5). oPartial or complete expulsion may occur, which can be unnoticed, leading to loss of contraceptive efficacy. (5.6). oEvaluate persistent enlarged ovarian follicles or ovarian cysts. (5.7). oBleeding patterns become altered, may remain irregular and amenorrhea may ensue. (5.8). 5.1 Risk of Ectopic Pregnancy. Evaluate women for ectopic pregnancy if they become pregnant with Mirena in place because the likelihood of pregnancy being ectopic is increased with Mirena. Approximately one-half of pregnancies that occur with Mirena in place are likely to be ectopic. Also consider the possibility of ectopic pregnancy in the case of lower abdominal pain, especially in association with missed menses or if an amenorrheic woman starts bleeding. The incidence of ectopic pregnancy in clinical trials with Mirena, which excluded women with history of ectopic pregnancy, was approximately 0.1% per year. The risk of ectopic pregnancy, in women who have history of ectopic pregnancy and use Mirena is unknown. Women with previous history of ectopic pregnancy, tubal surgery or pelvic infection carry higher risk of ectopic pregnancy. Ectopic pregnancy may result in loss of fertility.. 5.2 Risks with Intrauterine Pregnancy If pregnancy occurs while using Mirena, remove Mirena because leaving it in place may increase the risk of spontaneous abortion and preterm labor. Removal of Mirena or probing of the uterus may also result in spontaneous abortion. In the event of an intrauterine pregnancy with Mirena, consider the following:. Septic abortion In patients becoming pregnant with an IUS in place, septic abortion with septicemia, septic shock, and death may occur. Continuation of pregnancy If woman becomes pregnant with Mirena in place and if Mirena cannot be removed or the woman chooses not to have it removed, warn her that failure to remove Mirena increases the risk of miscarriage, sepsis, premature labor and premature delivery. Advise her of isolated reports of virilization of the female fetus following local exposure to LNG during pregnancy with an LNG IUS in place [see Use in Specific Populations 8.1)]. Follow her pregnancy closely and advise her to report immediately any symptom that suggests complications of the pregnancy. 5.3 Sepsis. Severe infection or sepsis, including Group streptococcal sepsis (GAS), have been reported following insertion of Mirena. In some cases, severe pain occurred within hours of insertion followed by sepsis within days. Because death from GAS is more likely if treatment is delayed, it is important to be aware of these rare but serious infections. Aseptic technique during insertion of Mirena is essential in order to minimize serious infections such as GAS.. 5.4 Pelvic Infection Promptly examine users with complaints of lower abdominal or pelvic pain, odorous discharge, unexplained bleeding, fever, genital lesions or sores. Remove Mirena in cases of recurrent endometritis or PID, or if an acute pelvic infection is severe or does not respond to treatment.. Pelvic Inflammatory Disease (PID). Mirena is contraindicated in the presence of known or suspected PID or in women with history of PID unless there has been subsequent intrauterine pregnancy [see Contraindications 4)]. IUDs have been associated with an increased risk of PID, most likely due to organisms being introduced into the uterus during insertion. In clinical trials, total combined upper genital infections were reported in 3.5% of Mirena users. More specifically, endometritis was reported in 2.1%, PID in 0.6%, and all other upper genital infections in <=0.5% of women overall. These infections occurred more frequently within the first year. In clinical trial with other IUDs1 and clinical trial with an IUD similar to Mirena, the highest rate occurred within the first month after insertion. Women at increased risk for PID PID is often associated with sexually transmitted infection (STI), and Mirena does not protect against STI. The risk of PID is greater for women who have multiple sexual partners, and also for women whose sexual partner(s) have multiple sexual partners. Women who have had PID are at increased risk for recurrence or re-infection. In particular, ascertain whether the woman is at increased risk of infection (for example, leukemia, acquired immune deficiency syndrome [AIDS], intravenous drug abuse).. Subclinical PID PID may be asymptomatic but still result in tubal damage and its sequelae.. Treatment of PID Following diagnosis of PID, or suspected PID, bacteriologic specimens should be obtained, and antibiotic therapy should be initiated promptly. Removal of Mirena after initiation of antibiotic therapy is usually appropriate.1 Actinomycosis. Actinomycosis has been associated with IUDs. Remove Mirena from symptomatic women and treat with antibiotics. The significance of actinomyces-like organisms on Pap smear in an asymptomatic IUD user is unknown, and so this finding alone does not always require Mirena removal and treatment. When possible, confirm Pap smear diagnosis with cultures.. 5.5 Perforation. Perforation (total or partial, including penetration/embedment of Mirena in the uterine wall or cervix) may occur most often during insertion, although the perforation may not be detected until sometime later. The incidence of perforation during clinical trials, which excluded breast-feeding women, was 0.1%. The risk of uterine perforation is increased in women who have recently given birth, and in women who are breastfeeding at the time of insertion. In large postmarketing safety study conducted in the US, the risk of uterine perforation was highest when insertion occurred within <= weeks postpartum, and also higher with breastfeeding at the time of insertion [see Adverse Reactions 6.2)]. The risk of perforation may be increased if Mirena is inserted when the uterus is fixed, retroverted or not completely involuted.If perforation occurs, locate and remove Mirena. Surgery may be required. Delayed detection or removal of Mirena in case of perforation may result in migration outside the uterine cavity, adhesions, peritonitis, intestinal perforations, intestinal obstruction, abscesses and erosion of adjacent viscera. In addition, perforation may reduce contraceptive efficacy and result in pregnancy.. 5.6 Expulsion. Partial or complete expulsion of Mirena may occur resulting in the loss of efficacy. Expulsion may be associated with symptoms of bleeding or pain, or it may be asymptomatic and go unnoticed. Mirena typically decreases menstrual bleeding over time; therefore, an increase of menstrual bleeding may be indicative of an expulsion. Consider further diagnostic imaging, such as x-ray, if expulsion is suspected based on ultrasound [see Warnings and Precautions (5.10)]. In clinical trials, 4.5% expulsion rate was reported over the 5-year study duration.The risk of expulsion is increased with insertions immediately after delivery and appears to be increased with insertion after second-trimester abortion based on limited data. In large postmarketing safety study conducted in the US, the risk of expulsion was lower with breastfeeding status [see Adverse Reactions 6.2)]. Remove partially expelled Mirena. If expulsion has occurred, new Mirena can be inserted any time the provider can be reasonably certain the woman is not pregnant.. 5.7 Ovarian Cysts. Because the contraceptive effect of Mirena is mainly due to its local effects within the uterus, ovulatory cycles with follicular rupture usually occur in women of fertile age using Mirena. Ovarian cysts have been reported in approximately 8% of women using Mirena. Most cysts are asymptomatic, although some may be accompanied by pelvic pain or dyspareunia.In most cases the ovarian cysts disappear spontaneously during two to three months observation. Evaluate persistent ovarian cysts. Surgical intervention is not usually required. 5.8 Bleeding Pattern Alterations Mirena can alter the bleeding pattern and result in spotting, irregular bleeding, heavy bleeding, oligomenorrhea and amenorrhea. During the first 3-6 months of Mirena use, the number of bleeding and spotting days may be higher and bleeding patterns may be irregular. Thereafter the number of bleeding and spotting days usually decreases but bleeding may remain irregular. If bleeding irregularities develop during prolonged treatment, appropriate diagnostic measures should be taken to rule out endometrial pathology.Amenorrhea develops in approximately 20% of Mirena users by one year. If significant change in bleeding develops during prolonged use, take appropriate diagnostic measures to rule out endometrial pathology. Consider the possibility of pregnancy if menstruation does not occur within six weeks of the onset of previous menstruation. Once pregnancy has been excluded, repeated pregnancy tests are generally not necessary in amenorrheic women unless indicated, for example, by other signs of pregnancy or by pelvic pain [see Clinical Studies 14.1)]. In most women with heavy menstrual bleeding, the number of bleeding and spotting days may also increase during the initial months of therapy but usually decrease with continued use; the volume of blood loss per cycle progressively becomes reduced [see Clinical Studies 14.2)]. 5.9 Breast Cancer Women who currently have or have had breast cancer, or have suspicion of breast cancer, should not use hormonal contraception, including Mirena, because some breast cancers are hormone-sensitive [see Contraindications 4)]. Spontaneous reports of breast cancer have been received during postmarketing experience with Mirena. Observational studies of the risk of breast cancer with use of LNG-releasing IUS do not provide conclusive evidence of increased risk.. 5.10 Clinical Considerations for Use and Removal. Use Mirena with caution after careful assessment if any of the following conditions exist, and consider removal of the system if any of them arise during use:oCoagulopathy or use of anticoagulantsoMigraine, focal migraine with asymmetrical visual loss or other symptoms indicating transient cerebral ischemiaoExceptionally severe headacheoMarked increase of blood pressureoSevere arterial disease such as stroke or myocardial infarctionIn addition, consider removing Mirena if any of the following conditions arise during use [see Contraindications 4)]:oUterine or cervical malignancy oJaundiceIf the threads are not visible or are significantly shortened, they may have broken or retracted into the cervical canal or uterus. Consider the possibility that the system may have been displaced (for example, expelled or perforated the uterus) [see Warnings and Precautions (5.5, 5.6)]. Exclude pregnancy and verify the location of Mirena, for example, by sonography, X-ray, or by gentle exploration of the cervical canal with suitable instrument. If Mirena is displaced, remove it. new Mirena may be inserted at that time or during the next menses if it is certain that conception has not occurred. If Mirena is in place with no evidence of perforation, no intervention is indicated.. oCoagulopathy or use of anticoagulants. oMigraine, focal migraine with asymmetrical visual loss or other symptoms indicating transient cerebral ischemia. oExceptionally severe headache. oMarked increase of blood pressure. oSevere arterial disease such as stroke or myocardial infarction. oUterine or cervical malignancy oJaundice.
