Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.ADVERSE REACTIONS The following adverse reactions have been reported in connection with the use of clotrimazole: erythema, stinging, blistering, peeling, edema, pruritius, urticaria, burning, and general irritation of the skin.
Clotrimazole Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.Drug Interactions Synergism or antagonism between clotrimazole and nystatin, or amphotericin B, or flucytosine against strains of C. albicans has not been reported.
Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.CLINICAL PHARMACOLOGY Clotrimazole is a broad-spectrum antifungal agent that is used for the treatment of dermal infections caused by various species of pathogenic dermatophytes, yeasts, and Malassezia furfur . The primary action of clotrimazole is against dividing and growing organisms. In vitro , clotrimazole exhibits fungistatic and fungicidal activity against isolates of Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, Microsporum canis , and Candida species including Candida albicans . In general, the in vitro activity of clotrimazole corresponds to that of tolnaftate and griseofulvin against the mycelia of dermatophytes ( Trichophyton, Microsporum , and Epidermophyton ), and to that of the polyenes (amphotericin B and nystatin) against budding fungi ( Candida ). Using an in vivo (mouse) and an in vitro (mouse kidney homogenate) testing system, clotrimazole and miconazole were equally effective in preventing the growth of the pseudomycelia and mycelia of Candida albicans . Strains of fungi having a natural resistance to clotrimazole are rare. Only a single isolate of Candida guilliermondi has been reported to have primary resistance to clotrimazole. No single-step or multiple-step resistance to clotrimazole has developed during successive passages of Candida albicans and Trichophyton mentagrophytes . No appreciable change in sensitivity was detected after successive passages of isolates of C. albicans, C. krusei , or C. pseudotropicalis in liquid or solid media containing clotrimazole. Also, resistance could not be developed in chemically induced mutant strains of polyene-resistant isolates of C. albicans . Slight, reversible resistance was noted in three isolates of C. albicans tested by one investigator. There is a single report that records the clinical emergence of a C. albicans strain with considerable resistance to flucytosine and miconazole, and with cross-resistance to clotrimazole; the strain remained sensitive to nystatin and amphotericin B. In studies of the mechanism of action, the minimum fungicidal concentration of clotrimazole caused leakage of intracellular phosphorus compounds into the ambient medium with concomitant breakdown of cellular nucleic acids and accelerated potassium efflux. Both these events began rapidly and extensively after addition of the drug. Clotrimazole appears to be well absorbed in humans following oral administration and is eliminated mainly as inactive metabolites. Following topical and vaginal administration, however, clotrimazole appears to be minimally absorbed. Six hours after the application of radioactive clotrimazole 1% cream and 1% solution onto intact and acutely inflamed skin, the concentration of clotrimazole varied from 100 mcg/cm 3 , in the stratum corneum to 0.5 to 1 mcg/cm 3 in the stratum reticulare, and 0.1 mcg/cm 3 in the subcutis. No measurable amount of radioactivity (≤0.001 mcg/mL) was found in the serum within 48 hours after application under occlusive dressing of 0.5 mL of the solution or 0.8 g of the cream. Only 0.5% or less of the applied radioactivity was excreted in the urine. Following intravaginal administration of 100 mg 14 C-clotrimazole vaginal tablets to nine adult females, an average peak serum level, corresponding to only 0.03 µg equivalents/mL of clotrimazole, was reached 1 to 2 days after application. After intravaginal administration of 5 g of 1% 14 C-clotrimazole vaginal cream containing 50 mg active drug, to five subjects (one with candidal colpitis), serum levels corresponding to approximately 0.01 µg equivalents/mL were reached between 8 and 24 hours after application.

Carcinogenesis and mutagenesis and impairment of fertility
Information about carcinogenic, mutagenic, or fertility impairment potential revealed by studies in animals. Information from human data about such potential is part of the warnings field.Carcinogenesis, Mutagenesis, and Impairment of Fertility An 18-month oral dosing study with clotrimazole in rats has not revealed any carcinogenic effect. In tests for mutagenesis, chromosomes of the spermatophores of Chinese hamsters which had been exposed to clotrimazole were examined for structural changes during the metaphase. Prior to testing, the hamsters had received five oral clotrimazole doses of 100 mg/kg body weight. The results of this study showed that clotrimazole had no mutagenic effect.
Laboratory tests

Pediatric use
Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.Pediatric Use Safety and effectiveness in pediatric patients have been established for clotrimazole when used as indicated and in the recommended dosage.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)Usage in Pregnancy Pregnancy Category B The disposition of 14 C-clotrimazole has been studied in humans and animals. Clotrimazole is very poorly absorbed following dermal application or intravaginal administration to humans. (See CLINICAL PHARMACOLOGY .) In clinical trials, use of vaginally applied clotrimazole in pregnant women in their second and third trimesters has not been associated with ill effects. There are, however, no adequate and well-controlled studies in pregnant women during the first trimester of pregnancy. Studies in pregnant rats with intravaginal doses up to 100 mg/kg have revealed no evidence of harm to the fetus due to clotrimazole. High oral doses of clotrimazole in rats and mice ranging from 50 to 120 mg/kg resulted in embryotoxicity (possibly secondary to maternal toxicity), impairment of mating, decreased litter size and number of viable young and decreased pup survival to weaning. However, clotrimazole was not teratogenic in mice, rabbits and rats at oral doses up to 200, 180 and 100 mg/kg, respectively. Oral absorption in the rat amounts to approximately 90% of the administered dose. Because animal reproduction studies are not always predictive of human response, this drug should be used only if clearly indicated during the first trimester of pregnancy.
Teratogenic effects
Pregnancy category A: Adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus in the first trimester of pregnancy, and there is no evidence of a risk in later trimesters. Pregnancy category B: Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women. Pregnancy category C: Animal reproduction studies have shown an adverse effect on the fetus, there are no adequate and well-controlled studies in humans, and the benefits from the use of the drug in pregnant women may be acceptable despite its potential risks. Pregnancy category D: There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but the potential benefits from the use of the drug in pregnant women may be acceptable despite its potential risks (for example, if the drug is needed in a life-threatening situation or serious disease for which safer drugs cannot be used or are ineffective). Pregnancy category X: Studies in animals or humans have demonstrated fetal abnormalities or there is positive evidence of fetal risk based on adverse reaction reports from investigational or marketing experience, or both, and the risk of the use of the drug in a pregnant woman clearly outweighs any possible benefit (for example, safer drugs or other forms of therapy are available).Pregnancy Category B The disposition of 14 C-clotrimazole has been studied in humans and animals. Clotrimazole is very poorly absorbed following dermal application or intravaginal administration to humans. (See CLINICAL PHARMACOLOGY .)
