Precautions

Systemic absorption of betamethasone may result in suppression of the hypothalmic-pituitary-adrenal axis; prolonged or excessive use may increase systemic absorption of the drug.

Pregnancy-Lactation

Pregnancy There are no available data on topical betamethasone dipropionate or clotrimazole use in pregnant women to identify drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes; observational studies suggest an increased risk of low birth weight infants with use of potent or very potent topical corticosteroid during pregnancy Advise pregnant women that therapy may increase risk of having a low birth weight infant and to use drug on the smallest area of skin and for shortest duration possible Animal data In an animal reproduction study, betamethasone dipropionate caused malformations (ie, umbilical hernias, cephalocele, and cleft palate) in pregnant rabbits when given by intramuscular route during organogenesis The available data do not allow calculation of relevant comparisons between systemic exposure of clotrimazole and/or betamethasone dipropionate observed in animal studies to systemic exposure that would be expected in humans after topical use of drug Lactation Advise a woman to apply drug to smallest area of skin and for shortest duration possible while breastfeeding; advise breastfeeding women not to apply drug directly to nipple and areola to avoid direct infant exposure

Mechanism of Action

Betamethasone dipropionate is a corticosteroid that prevents and reduce inflammation by depressing the migration of polymorphonuclear leukocytes and fibroblasts; reversing capillary permeability and lysosomal stabilisation at the cellular level. Clotrimazole is an antifungal agent that binds to phospholipids in the fungal cell membrane. It causes loss of essential intracellular components by altering cell wall permeability.
