Pharmacotherapeutic group: Antifungals for topical use, ATC code: D01AA01
Nystatin Perrigo is a mixture of antifungal polyenes produced by the growth of certain strains of Streptomyces noursei, or by any other means. It consists largely of Nystatin Perrigo A1.
Nystatin Perrigo is active against a wide range of yeasts and yeast-like fungi, including Candida albicans.
Nystatin Perrigo is a tetraene macrolide. There is no data available on the pharmacokinetics as it is not absorbed from the gastro-intestinal tract, skin or vagina and most of the use is topical. Microbial growth-inhibiting concentrations have been shown to be in the range 3-6mg/l.
Nystatin is not absorbed from intact skin or mucous membrane.
Nystatin Perrigo Oral Suspension BP contains sucrose. Patients with rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase insufficiency should not take this medicine. This should also be taken into account in patients with diabetes mellitus.

Nystatin Perrigo Oral Suspension contains sodium metabisulphite (E223) which may rarely cause severe hypersensitivity reactions and bronchospasm.

WARNINGSNo information provided.
PRECAUTIONS GeneralNystatin, topical preparations should not be used for the treatment of systemic, oral, intravaginal or ophthalmic infections.
If irritation or sensitization develops, treatment should be discontinued and appropriate measures taken as indicated. It is recommended that KOH smears, cultures, or other diagnostic methods be used to confirm the diagnosis of cutaneous or mucocutaneous candidiasis and to rule out infection caused by other pathogens.
Laboratory TestsIf there is a lack of therapeutic response, KOH smears, cultures, or other diagnostic methods should be repeated.
Carcinogenesis, Mutagenesis, Impairment of FertilityNo long-term animal studies have been performed to evaluate the carcinogenic potential of nystatin. No studies have been performed to determine the mutagenicity of nystatin or its effects on male or female fertility.
Pregnancy: Teratogenic EffectsCategory C. Animal reproduction studies have not been conducted with any nystatin topical preparation. It also is not known whether these preparations can cause fetal harm when used by a pregnant woman or can affect reproductive capacity. Nystatin topical preparations should be prescribed for a pregnant woman only if the potential benefit to the mother outweighs the potential risk to the fetus.
Nursing MothersIt is not known whether nystatin is excreted in human milk. Caution should be exercised when nystatin is prescribed for a nursing woman.
Pediatric UseSafety and effectiveness have been established in the pediatric population from birth to 16 years. (See DOSAGE AND ADMINISTRATION.)
Geriatric UseClinical studies with Nystatin Perrigo (Nystatin) Cream and Nystatin Perrigo (Nystatin) Topical Powder did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently than younger subjects. Other reported clinical experience has not identified differences in responses between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
