Onabet B Cream is a dermatological medication indicated for the topical treatment of fungal infection of the skin with eczema. Fungal infection is a skin disease in which a fungus attacks the tissue and causes infection. Fungal infections may be contagious (spread from one person to another).

Onabet B Cream is a combination of two drugs, namely: Sertaconazole nitrate (antifungal) and Beclomethasone dipropionate (corticosteroid). Sertaconazole nitrate works by damaging the fungal cell membranes, ultimately killing fungi. On the other hand, Beclomethasone dipropionate works by inhibiting the release of certain chemical messengers in the body that cause redness, itching, and swelling.
