Lactifem Itch Vaginal Cream Vaginal Cream is a combination of two medicines: Lidocaine and Clotrimazole, which treats ear infections. Lidocaine is a local anesthetic which works by blocking pain signals from the nerves to brain, thereby decreasing pain sensation in the ear. Clotrimazole is an antifungal which stops the growth of fungi in the ear by preventing them from forming their own protective covering.
