Description

Mometamax Otic Suspension for Dogs is a powerful, once-daily ear treatment designed to relieve and resolve ear infections caused by susceptible bacteria and fungi. This veterinarian-recommended otic suspension combines three potent active ingredients—gentamicin sulfate (antibacterial), mometasone furoate (anti-inflammatory corticosteroid), and clotrimazole (antifungal)—to provide comprehensive relief from otitis externa and related symptoms such as itching, inflammation, and discharge.

Key Benefits of Mometamax:

  • Once-daily (SID) dosing: Simplifies treatment for pet owners and reduces stress for dogs.
  • Fast and effective relief: Combats ear infections caused by common bacterial and fungal pathogens.
  • Low-volume application: As few as 4 drops per ear are needed per dose.
  • Veterinary-trusted formula: Proven in both dermatological and allergy-related clinical studies.
  • Advanced antifungal protection: Clotrimazole outperforms Nystatin for potency against yeast and fungi.
  • Anti-inflammatory benefits: Mometasone provides strong corticosteroid action—7.7 times more potent than betamethasone—with a favorable safety profile.
  • Promotes treatment compliance: Easier for pet owners to administer, enhancing adherence to therapy protocols.
  • No observed steroid-related side effects: Safe for use in dogs with minimal risk of systemic complications.

How It Works:

Gentamicin sulfate eliminates bacteria by disrupting their protein production. Clotrimazole targets yeast and fungal organisms commonly responsible for otitis externa, such as Malassezia pachydermatis. Mometasone furoate, a synthetic corticosteroid, reduces inflammation, redness, and itching caused by allergic reactions or chronic ear infections.

Indications:

Mometamax is indicated for the treatment of otitis externa in dogs caused by susceptible strains of fungi and bacteria, including:

  • Malassezia pachydermatis (yeast)
  • Pseudomonas spp., including P. aeruginosa
  • Coagulase-positive Staphylococci
  • Enterococcus faecalis
  • Proteus mirabilis
  • Beta-hemolytic Streptococci

Note: Always consult your veterinarian before using Mometamax Otic Suspension. Not for use in cats unless directed by a veterinarian.

Dosage & Administration:

Before using Mometamax Otic Suspension, clean and dry your dog’s external ear canal thoroughly. Ensure the eardrum (tympanic membrane) is intact before administering the medication.

  • Dogs under 30 lbs: Instill 4 drops once daily into the affected ear(s) using the 7.5 g, 15 g, or 30 g bottle, or 2 drops from the 215 g bottle.
  • Dogs 30 lbs and over: Instill 8 drops once daily into the affected ear(s) using the 7.5 g, 15 g, or 30 g bottle, or 4 drops from the 215 g bottle.

Treatment should continue for 7 consecutive days unless otherwise directed by your veterinarian.

Caution:

Federal law restricts this drug to use by or on the order of a licensed veterinarian.

Contraindications:

  • Discontinue use if hypersensitivity to any ingredient occurs.
  • Do not use in dogs with ruptured eardrums.
  • Avoid concurrent use with drugs known to cause ototoxicity.

Warnings:

  • Temporary hearing loss or deafness may occur in sensitive dogs, especially geriatric patients.
  • Discontinue use if vestibular or auditory dysfunction occurs and flush ears with a non-ototoxic solution.
  • Corticosteroids may cause birth defects in animals if used during pregnancy (e.g., cleft palate, limb deformities).
  • Late pregnancy use may induce premature labor, fetal death, or complications during birth.

Precautions:

  • Confirm the tympanic membrane is intact before application to prevent inner ear damage.
  • Use beyond the 7-day period may delay healing of the ear canal.
  • Discontinue use if resistant bacteria or fungi overgrow during treatment.
  • Avoid ingestion. Topical corticosteroids may lead to systemic effects such as fluid retention, increased urination, or immunosuppression.
  • Wean pets gradually if they have recently been treated with corticosteroids to avoid adrenal suppression.

Possible Side Effects:

Gentamicin: Risk of nephrotoxicity, vestibular, and cochlear damage if used improperly or on damaged skin.

Mometasone: May cause liver enzyme elevations, appetite changes, increased thirst/urination, and in rare cases, signs of Cushing's syndrome.

Clotrimazole: Rarely causes skin irritation, redness, itching, or swelling.

General Observations: In clinical trials, less than 1% of dogs experienced side effects such as ataxia, proprioceptive deficits, increased water consumption, inflammation of the pinna, or diarrhea.

Storage Instructions:

  • Store between 2°C and 25°C (36°F and 77°F).
  • Shake well before each use.
