Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS Most common adverse reactions reported for clotrimazole and betamethasone dipropionate cream were paraesthesia in 1.9% of patients and rash, edema, and secondary infections each in less than 1% of patients. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Taro Pharmaceuticals U.S.A., Inc., at 1-866-923-4914 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In clinical trials common adverse reaction reported for clotrimazole and betamethasone dipropionate cream was paresthesia in 1.9% of patients. Adverse reactions reported at a frequency < 1% included rash, edema, and secondary infection. 6.2 Postmarketing Experience Because adverse reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following local adverse reactions have been reported with topical corticosteroids: itching, irritation, dryness, folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, maceration of the skin, skin atrophy, striae, miliaria, capillary fragility (ecchymoses), telangiectasia, and sensitization (local reactions upon repeated application of product). Ophthalmic adverse reactions of blurred vision, cataracts, glaucoma, increased intraocular pressure, and central serous chorioretinopathy have been reported with the use of topical corticosteroids, including topical betamethasone products. Adverse reactions reported with the use of clotrimazole are: erythema, stinging, blistering, peeling, edema, pruritus, urticaria, and general irritation of the skin.

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary There are no available data on topical betamethasone dipropionate or clotrimazole use in pregnant women to identify a clotrimazole and betamethasone dipropionate cream associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Observational studies suggest an increased risk of low birthweight infants with the use of potent or very potent topical corticosteroid during pregnancy. Advise pregnant women that clotrimazole and betamethasone dipropionate cream may increase the risk of having a low birthweight infant and to use clotrimazole and betamethasone dipropionate cream on the smallest area of skin and for the shortest duration possible. There have been no reproduction studies performed in animals or humans with the combination of clotrimazole and betamethasone dipropionate. In an animal reproduction study, betamethasone dipropionate caused malformations (i.e., umbilical hernias, cephalocele, and cleft palate) in pregnant rabbits when given by the intramuscular route during organogenesis [see Data ] . The available data do not allow the calculation of relevant comparisons between the systemic exposure of clotrimazole and/or betamethasone dipropionate observed in the animal studies to the systemic exposure that would be expected in humans after topical use of clotrimazole and betamethasone dipropionate cream. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Clotrimazole Studies in pregnant rats treated during organogenesis with intravaginal doses up to 100 mg/kg/day revealed no evidence of fetotoxicity due to clotrimazole exposure. No increase in fetal malformations was noted in...
