Mometamax® Otic Suspension for Dogs is used to treat inflammation and bacterial infections of the canine otitis externa (ear). Each gram of Mometamax Otic Suspension contains gentamicin sulfate, USP equivalent to 3 mg gentamicin base; mometasone furoate monohydrate equivalent to 1 mg mometasone; and 10 mg clotrimazole, USP in a mineral oil-based system containing a plasticized hydrocarbon gel. Gentamicin is a broad-spectrum antibiotic, which kills bacteria. Mometasone is a potent corticosteroid that relieves inflammation. Clotrimazole is an effective antifungal agent that is effective against yeast. The external ear canal should be thoroughly cleaned and dried before treatment.
