  • Antibacterial Effects (Gentamicin): Effective against a wide variety of Gram-positive and Gram-negative bacteria
  • Provides Reliable Relief: Eases discomfort and irritation for mild to moderate cases of Canine Otitis Externa.

How does Mometamax Otic Suspension work?

Mometamax is an FDA approved, veterinary medication used to treat ear infections in dogs. It is a combination of three active ingredients: mometasone furoate, gentamicin sulfate, and clotrimazole. Each component plays a specific role in treating ear infections: Mometasone Furoate: This is a potent corticosteroid that reduces inflammation, itching, and swelling in the ear. It helps to relieve the symptoms associated with ear infections. Gentamicin Sulfate:This is an antibiotic that targets and kills bacteria causing the infection. It is effective against a wide range of bacteria, including those commonly responsible for ear infections in dogs. Clotrimazole: This is an antifungal agent that treats and prevents fungal infections in the ear. It is especially useful in treating infections caused by yeast, which are common in dogs' ears.

Cautions:

For Otic Use in Dogs Only. Federal law restricts this drug to use by or on the order of a licensed veterinarian. Keep this and all drugs out of the reach of children. Do not use Mometamax Otic Suspension in pregnant dogs. The use of these components has been associated with deafness or partial hearing loss in a small number of sensitive dogs (e.g., geriatric), although it is usually temporary. If hearing or vestibular dysfunction is noted, discontinue use immediately and flush the ear canal thoroughly with a non-ototoxic solution. If hypersensitivity to any of the components occurs, treatment should be discontinued and appropriate therapy instituted. Concomitant use of drugs known to induce ototoxicity should be avoided. Do not use in dogs with known tympanic perforation. Administration of recommended doses beyond 7 days may result in delayed wound healing. Avoid ingestion. For complete safety information, refer to the product label.

What is the most important information I should know about Mometamax Otic Suspension?

Mometamax Otic Suspension is a prescription medication FDA approved for use in dogs only. It is available in 7.5 gm, 15 gm, 30 gm plastic dropper bottles. Use this medication for the full amount of time prescribed by your veterinarian, even if your pet appears to be better. Symptoms may improve before the infection is completely healed.

What should I discuss with my veterinarian before giving Mometamax Otic Suspension to my pet?

Tell your veterinarian if your dog is pregnant, allergic to any of the ingredients in Mometamax Otic Suspension, has perforated eardrums, or is currently taking any other medications, including over-the-counter medicines, vitamins, minerals, and herbal products.

How should Mometamax Otic Suspension be applied?

Before instilling any medication into the ear, examine the external ear canal thoroughly to be certain the tympanic membrane is not ruptured in order to avoid the possibility of transmitting infection to the middle ear as well as damaging the cochlea or vestibular apparatus from prolonged contact. Shake well before use. The external ear canal should be thoroughly cleaned and dried before treatment. Verify that the eardrum is intact. For dogs weighing less than 30 lbs, instill 4 drops from the 7.5 g, 15 g, and 30 g bottles (2 drops from the 215 g bottle) of Mometamax once daily into the ear canal. For dogs weighing 30 lbs or more, instill 8 drops from the 7.5 g, 15 g, and 30 g bottles (4 drops from the 215 g bottle) once daily into the ear canal. Therapy should continue for 7 consecutive days.

What are the Potential Side Effects of Mometamax Otic Suspension

  • Gentamicin: Prolonged topical use, especially on large wounds or damaged skin, can lead to vestibular, cochlear, and renal toxicity, particularly in cases of renal insufficiency.
  • Mometasone: Possible effects include enzyme elevations (ALP and ALT), weight loss, anorexia, increased thirst and urination, neutrophilia, lymphopenia, and Cushing's syndrome with prolonged steroid use.
  • Clotrimazole: Occasional side effects include skin irritation, such as erythema, stinging, blistering, peeling, edema, pruritus, and general irritation.
  • Mometamax Otic Suspension: Less than 1% of dogs in field studies showed ataxia, proprioceptive deficits, increased water consumption, inflammation of the pinna, and diarrhea.
  • Consult your veterinarian for any unusual or bothersome side effects.

What happens if I miss giving a dose of Mometamax Otic Suspension?

Give the missed dose as soon as you remember. If it is nearly time for the next dose, skip the missed dose and resume the regular dosing schedule. Do not double the dose.

What happens if I overdose my pet on Mometamax Otic Suspension?

If you suspect that your pet has received an overdose of Mometamax Otic Suspension, consult your veterinarian or emergency veterinary clinic immediately.

What should I avoid while applying Mometamax Otic Suspension?

Avoid using any other medications in your pet's ear unless instructed to by your veterinarian. Do not use Mometamax Otic Suspension in dogs allergic to it or any of the individual ingredients. Use with caution in pregnant animals. Do not use in dogs with perforated eardrums. Discontinue use of this medication if hearing loss is noted during treatment. Use of this product beyond the recommended dose of 7 days may result in delayed wound healing.

What other drugs will affect Mometamax Otic Suspension?
