What is clotrimazole otic?
Clotrimazole otic is a topical antifungal medication used in the treatment of otitis externa (inflammation of the external ear) associated with susceptible strains of yeast and other fungal organisms in cats, dogs, and rabbits. It may be part of combination product containing antimicrobials and/or steroids.
Its use may be off label (extra label) depending on formulation. Many drugs are commonly prescribed for off-label use in veterinary medicine.
“Off label” means the drug is being used in a way that has not been reviewed or approved by the U.S. Food and Drug Administration (FDA) or Health Canada. In these instances, follow your veterinarian’s directions and cautions very carefully, as they may be significantly different from those on the label.
