Side effects are expected to be minimal with the proper topical use of this product.

Gentamicin: While aminoglycosides are absorbed poorly from skin, increased absorption may occur when aminoglycosides are applied topically for prolonged periods of time to large wounds, burns, or any denuded skin, particularly if there is renal insufficiency. All aminoglycosides have the potential to produce reversible and irreversible vestibular, cochlear and renal toxicity.

Betamethasone: Side effects such as liver enzyme elevations, weight loss, anorexia, polydipsia, and polyuria have occurred following the use of parenteral or systemic (oral) synthetic corticosteroids in dogs. Vomiting and diarrhea (occasionally bloody) have been observed in dogs and cats. Cushing's Syndrome in dogs has been reported in association with prolonged or repeated steroid therapy.

Clotrimazole: The following have been reported occasionally in humans in connection with the use of clotrimazole: erythema (red swollen skin), stinging, blistering, peeling, edema, pruritus, urticaria, and general irritation of the skin not present before therapy.
