DRUG ABUSE AND DEPENDENCE SECTION.


9 DRUG ABUSE AND DEPENDENCE. Levonorgestrel is not controlled substance. There is no information about dependence associated with the use of Plan B.

PREGNANCY SECTION.


8.1 Pregnancy. Many studies have found no harmful effects on fetal development associated with long-term use of contraceptive doses of oral progestins. The few studies of infant growth and development that have been conducted with progestin-only pills have not demonstrated significant adverse effects.

SPL UNCLASSIFIED SECTION.


5.1 Ectopic Pregnancy. Ectopic pregnancies account for approximately 2% of all reported pregnancies. Up to 10% of pregnancies reported in clinical studies of routine use of progestin-only contraceptives are ectopic. history of ectopic pregnancy is not contraindication to use of this emergency contraceptive method. Healthcare providers, however, should consider the possibility of an ectopic pregnancy in women who become pregnant or complain of lower abdominal pain after taking Plan B. follow-up physical or pelvic examination is recommended if there is any doubt concerning the general health or pregnancy status of any woman after taking Plan B.

DOSAGE & ADMINISTRATION SECTION.


2 DOSAGE AND ADMINISTRATION. Take one tablet of Plan orally as soon as possible within 72 hours after unprotected intercourse or known or suspected contraceptive failure. Efficacy is better if the tablet is taken as soon as possible after unprotected intercourse. The second tablet should be taken 12 hours after the first dose. Plan can be used at any time during the menstrual cycle.If vomiting occurs within two hours of taking either dose of medication, consideration should be given to repeating the dose. The first tablet is taken orally as soon as possible within 72 hours after unprotected intercourse. The second tablet should be taken 12 hours after the first dose. Efficacy is better if Plan is taken as soon as possible after unprotected intercourse. (2).

CLINICAL STUDIES SECTION.


14 CLINICAL STUDIES. double-blind, randomized, multinational controlled clinical trial in 1,955 evaluable women (mean age 27) compared the efficacy and safety of Plan (one 0.75 mg tablet of levonorgestrel taken within 72 hours of unprotected intercourse, and one tablet taken 12 hours later) to the Yuzpe regimen (two tablets each containing 0.25 mg levonorgestrel and 0.05 mg ethinyl estradiol, taken within 72 hours of intercourse, and two additional tablets taken 12 hours later). After single act of intercourse occurring anytime during the menstrual cycle, the expected pregnancy rate of 8% (with no contraceptive use) was reduced to approximately 1% with Plan B.Emergency contraceptives are not as effective as routine hormonal contraception since their failure rate, while low based on single use, would accumulate over time with repeated use [see INDICATIONS AND USAGE (1)]. At the time of expected menses, approximately 74% of women using Plan had vaginal bleeding similar to their normal menses, 14% bled more than usual, and 12% bled less than usual. The majority of women (87%) had their next menstrual period at the expected time or within 7 days, while 13% had delay of more than days beyond the anticipated onset of menses.

CONTRAINDICATIONS SECTION.


4 CONTRAINDICATIONS. Plan is contraindicated for use in the case of known or suspected pregnancy.. Known or suspected pregnancy. (4).

ADVERSE REACTIONS SECTION.


6 ADVERSE REACTIONS. The most common adverse reactions (>= 10%) in the clinical trial included menstrual changes (26%), nausea (23%), abdominal pain (18%), fatigue (17%), headache (17%), dizziness (11%) and breast tenderness (11%).

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenicity: There is no evidence of increased risk of cancer with short-term use of progestins. There was no increase in tumorgenicity following administration of levonorgestrel to rats for years at approximately ug/day, to dogs for years at up to 0.125 mg/kg/day, or to rhesus monkeys for 10 years at up to 250 ug/kg/day. In another year dog study, administration of levonorgestrel at 0.5 mg/kg/day did increase the number of mammary adenomas in treated dogs compared to controls. There were no malignancies.Genotoxicity: Levonorgestrel was not found to be mutagenic or genotoxic in the Ames Assay, in vitro mammalian culture assays utilizing mouse lymphoma cells and Chinese hamster ovary cells, and in an in vivo micronucleus assay in mice. Fertility: There are no irreversible effects on fertility following cessation of exposures to levonorgestrel or progestins in general.

CLINICAL PHARMACOLOGY SECTION.


12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Emergency contraceptive pills are not effective if woman is already pregnant. Plan is believed to act as an emergency contraceptive principally by preventing ovulation or fertilization (by altering tubal transport of sperm and/or ova). In addition, it may inhibit implantation (by altering the endometrium). It is not effective once the process of implantation has begun.. 12.3 Pharmacokinetics. AbsorptionNo specific investigation of the absolute bioavailability of Plan in humans has been conducted. However, literature indicates that levonorgestrel is rapidly and completely absorbed after oral administration (bioavailability about 100%) and is not subject to first pass metabolism.After single dose of Plan (0.75 mg) administered to 16 women under fasting conditions, maximum serum concentrations of levonorgestrel were 14.1 7.7 ng/mL (mean SD) at an average of 1.6 0.7 hours.Table 2: Pharmacokinetic Parameter Values Following Single Dose Administration of Plan (Levonorgestrel) Tablets 0.75 mg to Healthy Female Volunteers under Fasting ConditionsMean (+- SD)Cmax (ng/mL)Tmax (h)CL(L/h)Vd (L)t 1/2 (h)AUCinf (ng/mL.h)Levonorgestrel14.1 (7.7)1.6 0.7)7.7 (2.7)260.024.4 (5.3)123.1 (50.1)Cmax maximum concentrationTmax time to maximum concentrationCL clearanceVd volume of distributiont1/2 elimination half lifeAUCinf area under the drug concentration curve from time to infinityEffect of Food: The effect of food on the rate and the extent of levonorgestrel absorption following single oral administration of Plan has not been evaluated. DistributionThe apparent volume of distribution of levonorgestrel 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.MetabolismFollowing absorption, levonorgestrel is conjugated at the 17-OH position to form sulfate conjugates and, to lesser extent, glucuronide conjugates in plasma. Significant amounts of conjugated and unconjugated 3, 5-tetrahydrolevonorgestrel are also present in plasma, along with much smaller amounts of 3, 5-tetrahydrolevonorgestrel and 16hydroxylevonorgestrel. Levonorgestrel 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 the wide variation observed in levonorgestrel concentrations among users. ExcretionAbout 45% of levonorgestrel and its metabolites are excreted in the urine and about 32% are excreted in feces, mostly as glucuronide conjugates.Specific Populations Pediatric: This product is not intended for use in the pediatric (pre-menarcheal) population, and pharmacokinetic data are not available for this population.Geriatric: This product is not intended for use in postmenopausal women and pharmacokinetic data are not available for this population.Race: No formal studies have evaluated the effect of race on pharmacokinetics of Plan B. However, clinical trials demonstrated higher pregnancy rate in Chinese women with both Plan and the Yuzpe regimen (another form of emergency contraception). The reason for this apparent increase in the pregnancy rate with emergency contraceptives in Chinese women is unknown [see USE IN SPECIFIC POPULATIONS (8.6)].Hepatic Impairment: No formal studies were conducted to evaluate the effect of hepatic disease on the disposition of Plan B. Renal Impairment: No formal studies were conducted to evaluate the effect of renal disease on the disposition of Plan B. Drug-Drug InteractionsNo formal drug-drug interaction studies were conducted with Plan [see DRUG INTERACTIONS (7)].

WARNINGS AND PRECAUTIONS SECTION.


5 WARNINGS AND PRECAUTIONS. Ectopic Pregnancy: Women who become pregnant or complain of lower abdominal pain after taking Plan should be evaluated for ectopic pregnancy. (5.1) Plan is not effective in terminating an existing pregnancy. (5.2 Effect on menses: Plan may alter the next expected menses. If menses is delayed beyond week, pregnancy should be considered. (5.3)STI/HIV: Plan does not protect against STI/HIV. (5.4). Ectopic Pregnancy: Women who become pregnant or complain of lower abdominal pain after taking Plan should be evaluated for ectopic pregnancy. (5.1) Plan is not effective in terminating an existing pregnancy. (5.2 . Effect on menses: Plan may alter the next expected menses. If menses is delayed beyond week, pregnancy should be considered. (5.3). STI/HIV: Plan does not protect against STI/HIV. (5.4). 5.1 Ectopic Pregnancy. Ectopic pregnancies account for approximately 2% of all reported pregnancies. Up to 10% of pregnancies reported in clinical studies of routine use of progestin-only contraceptives are ectopic. history of ectopic pregnancy is not contraindication to use of this emergency contraceptive method. Healthcare providers, however, should consider the possibility of an ectopic pregnancy in women who become pregnant or complain of lower abdominal pain after taking Plan B. follow-up physical or pelvic examination is recommended if there is any doubt concerning the general health or pregnancy status of any woman after taking Plan B.. 5.2 Existing Pregnancy Plan is not effective in terminating an existing pregnancy.. 5.3 Effects on Menses. Some women may experience spotting few days after taking Plan B. Menstrual bleeding patterns are often irregular among women using progestin-only oral contraceptives and women using levonorgestrel for postcoital and emergency contraception. If there is delay in the onset of expected menses beyond week, consider the possibility of pregnancy.. 5.4 STI/HIV. Plan does not protect against HIV infection (AIDS) or other sexually transmitted infections (STIs).. 5.5 Physical Examination and Follow-up A physical examination is not required prior to prescribing Plan B. follow-up physical or pelvic examination is recommended if there is any doubt concerning the general health or pregnancy status of any woman after taking Plan B.. 5.6 Fertility Following Discontinuation. rapid return of fertility is likely following treatment with Plan for emergency contraception; therefore, routine contraception should be continued or initiated as soon as possible following use of Plan to ensure ongoing prevention of pregnancy.
