The active ingredient in Otomax is a combination of gentamicin sulfate, clotrimazole, and betamethasone valerate.
Gentamicin sulfate is a broad-spectrum antibacterial agent that works by stopping bacterial growth. Clotrimazole is an antifungal agent that helps treat fungal infections by damaging the fungal cell membrane. Betamethasone valerate is a corticosteroid with anti-inflammatory effects that reduces redness, swelling, itching, and irritation in the external ear canal.
