Nystatin Vaginal Insert

Nystatin Vaginal Insert Description

Nystatin is an antimycotic polyene antibiotic obtained from Streptomyces noursei.

Nystatin Vaginal Inserts, USP are available as oval-shaped compressed inserts for intravaginal administration, each containing 100,000 units Nystatin, USP. Inactive ingredients include corn starch, ethylcellulose, anhydrous lactose, microcrystalline cellulose, polyethylene glycol and stearic acid.

Nystatin Vaginal Insert - Clinical Pharmacology

Nystatin is both fungi-static and fungicidal in vitro against a wide variety of yeasts and yeast-like fungi. Nystatin acts by binding to sterols in the cell membrane of sensitive fungi with a resultant change in membrane permeability allowing leakage of intracellular components. Nystatin exhibits no appreciable activity against bacteria, protozoa, trichomonads or viruses.

Nystatin is not absorbed from intact skin or mucous membranes.

Indications and Usage for Nystatin Vaginal Insert

Nystatin Vaginal Inserts, USP are effective for the local treatment of vulvovaginal candidiasis (moniliasis). The diagnosis should be confirmed, prior to therapy, by KOH smears and/or cultures. Other pathogens commonly associated with vulvovaginitis (Trichomonas and Haemophilus vaginalis) do not respond to nystatin and should be ruled out by appropriate laboratory methods.

Contraindications

This preparation is contraindicated in patients with a history of hypersensitivity to any of its components.

Precautions

General

Discontinue treatment if sensitization or irritation is reported during use.

Information for Patients

The patient should be informed of symptoms of sensitization or irritation and told to report them promptly.

The patient should be warned against interruption or discontinuation of medication even during menstruation and even though symptomatic relief may occur within a few days.

The patient should be advised that adjunctive measures such as therapeutic douches are unnecessary and sometimes inadvisable, but cleansing douches may be used by nonpregnant women, if desired, for esthetic purposes.

Laboratory Tests

If there is a lack of response to Nystatin Vaginal Inserts, USP, appropriate microbiological studies should be repeated to confirm the diagnosis and rule out other pathogens before instituting another course of antimycotic therapy (see INDICATIONS AND USAGE).
