NURSING MOTHERS SECTION.

Nursing Mothers. It is not known whether nystatin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when nystatin is administered to nursing woman.

OVERDOSAGE SECTION.

OVERDOSAGE. Oral doses of nystatin in excess of five million units daily have caused nausea and gastrointestinal upset. There have been no reports of serious toxic effects of superinfections (see CLINICAL PHARMACOLOGY, Pharmacokinetics).

PHARMACOKINETICS SECTION.

Pharmacokinetics. Gastrointestinal absorption of nystatin is insignificant. Most orally administered nystatin is passed unchanged in the stool. In patients with renal insufficiency receiving oral therapy with conventional dosage forms, significant plasma concentrations of nystatin may occasionally occur.

GENERAL PRECAUTIONS SECTION.

General. This medication is not to be used for the treatment of systemic mycoses. Discontinue treatment if sensitization or irritation is reported during use.

HOW SUPPLIED SECTION.

HOW SUPPLIED. Nystatin Oral Suspension USP, 100,000 USP Nystatin Units per mL, is available as fruit flavored, light creamy yellow, ready-to-use suspension in unit dose cups of mL, 10 cups per tray.

INDICATIONS & USAGE SECTION.

INDICATIONS AND USAGE. Nystatin Oral Suspension is indicated for the treatment of candidiasis in the oral cavity.

MICROBIOLOGY SECTION.

Microbiology. Nystatin is both fungistatic and fungicidal in vitro against wide variety of yeasts and yeast-like fungi. Candida albicans demonstrates no significant resistance to nystatin in vitro on repeated subculture in increasing levels of nystatin; other Candida species become quite resistant. Generally, resistance does not develop in vivo. Nystatin acts by binding to sterols in the cell membrane of susceptible Candida species with resultant change in membrane permeability allowing leakage of intracellular components. Nystatin exhibits no appreciable activity against bacteria, protozoa, or viruses.

ADVERSE REACTIONS SECTION.

ADVERSE REACTIONS. Nystatin is well tolerated even with prolonged therapy. Oral irritation and sensitization have been reported. (See PRECAUTIONS: General). Gastrointestinal: Diarrhea (including one case of bloody diarrhea), nausea, vomiting, gastrointestinal upset/disturbances.Dermatologic: Rash, including urticaria has been reported rarely. Stevens-Johnson syndrome has been reported very rarely.Other: Tachycardia, bronchospasm, facial swelling, and non-specific myalgia have also been rarely reported.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

Carcinogenesis, Mutagenesis, Impairment of Fertility. No long-term animal studies have been performed to evaluate carcinogenic potential. There also have been no studies to determine mutagenicity or whether this medication affects fertility in males or females.

DOSAGE & ADMINISTRATION SECTION.

DOSAGE AND ADMINISTRATION. INFANTS: mL (200,000 units) four times daily (in infants and young children, use calibrated dropper to place one-half of dose in each side of mouth and avoid feeding for to 10 minutes). NOTE: Limited clinical studies in premature and low birth weight infants indicate that mL four times daily is effective. CHILDREN AND ADULTS: 4-6 mL (400,000 to 600,000 units) four times daily (one-half of dose in each side of mouth). The preparation should be retained in the mouth as long as possible before swallowing. Continue treatment for at least 48 hours after perioral symptoms have disappeared and cultures demonstrate eradication of Candida albicans.
