Ear Infection Antibiotics for Dogs

Otomax Ointment is an antibiotic for the treatment of acute and chronic ear infections in dogs. Otomax pet meds work on fungal and bacterial infections that are susceptible to gentamicin. Otomax also contains Betamethasone which is a topical corticosteroid.

Otomax treats a wide range of bacterial and fungal infections in the ears of dogs while working to relieve itching, inflammation, and irritation during the recovery period. Otomax is effective against both acute and chronic infections.

Benefits of Otomax:

  • Treats bacterial and fungal infections
  • Reduces inflammation and itching
  • Minimizes odor from the ear
  • Clears infections in one week
  • Treats both chronic and acute infections
  • Prescription-strength treatment

It is a violation of Federal Law to use this product in a manner inconsistent with its labeling.

One active ingredient in Otomax, gentamicin sulfate, is an aminoglycoside antibiotic effective against a variety of gram-negative and gram-positive bacteria. Gentamicin works by inhibiting normal protein synthesis in Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and other susceptible microorganisms. Betamethasone provides antipruritic and anti-inflammatory actions, and clotrimazole is a broad-spectrum antifungal agent.

Active Ingredients (per gram): Gentamicin Sulfate 3 mg, Betamethasone Valerate 1 mg, Clotrimazole 10 mg


Keep this product out of reach of children and animals. Do not use or store in or near open flame or heat.

Otomax is intended for use on dogs only. Not for use on cats or other animals. Not for humans.

CAUTION: Do not use Otomax Ointment on dogs with an eardrum perforation.

Use of this medication has been known to cause partial hearing loss or deafness in a small number of dogs. These dogs account for a small percentage of those treated with Otomax and the risk appears confined to sensitive populations, such as geriatric dogs. In most cases, hearing loss is temporary. If hearing loss occurs during treatment, discontinue use of the medication immediately, flush the ear canal, and consult your veterinarian.

The corticosteroid component may cause birth defects if administered to pregnant dogs. Corticosteroid use has caused cleft palate, deformed forelegs, anasarca, phocomelia, and other congenital anomalies in offspring born to dogs undergoing treatment.

Do not ingest. Doing so can cause potassium loss, fluid and/or sodium retention, polydipsia, weight gain, and/or polyuria.

Side effects of Otomax may include anorexia, weight loss, polyuria, polydipsia, diarrhea, vomiting, blistering, peeling, edema, itching, hives, and irritation.
