Hello. Otomax is a broad spectrum medication the contains an antibiotic, antifungal as well as a steroid. It is possible that the steroid is preventing the lesion from healing. I would talk to your vet about this & switching to another antibiotic such as silver sulfadiazine. If it still does not heal, the lesion may need to be cultured or biopsied to identify why it is not healing. Thanks for using Petco Pet Education Center, formerly Petcoach.
