Otomax ointment by Merck is a treatment for ear infections due to bacteria or yeast. It is labeled for use in dogs, but veterinarians will frequently prescribe it for cats, horses, and other animals as well. 
Otomax contains three separate medicines - gentamicin, betamethasone, and clotrimazole, and thus can be used for many different types of ear infection.


  • Treats a wide array of bacterial ear infections
  • Contains an antifungal (clotrimazole) to treat ear infections cause by yeast
  • Also contains a steroid to help relieve swelling and itchiness in the ear while it works to cure the root cause
  • Requires a prescription from your veterinarian


Ensure the ear canal is clean and dry before administering Otomax ointment. Trimming away hair from the application spot can help ensure accurate dosing. Massage the medication into the ear as best you can while wearing gloves.
