Contra Indications
Patients who are sensitive to clotrimazole, betamethasone dipropionate, other corticosteroids or imidazoles, or to any ingredient in these preparations.
Precautions
Systemic absorption of topical corticosteroids can produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency after withdrawal of treatment. Manifestations of Cushing's syndrome, hyperglycemia, and glucosuria can also be produced in some patients by systemic absorption of topical corticosteroids while on treatment.
Conditions which augment systemic absorption include use over large surface areas, prolonged use, and use under occlusive dressings.
If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application, or to substitute a less potent corticosteroid.
Pediatric patients may be more susceptible to systemic toxicity from equivalent doses due to their larger skin surface to body mass ratios

Mechanism of Action
Betamethasone is a corticosteroid with mainly glucocorticoid activity. It prevents and controls inflammation by controlling the rate of protein synthesis, depressing the migration of polymorphonuclear leukocytes and fibroblasts, and reversing capillary permeability and lysosomal stabilisation.
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.
