Use as prescribed.

CAUTION: Not for use in dogs with a hypersensitivity to any of its ingredients.

An animal having an allergic reaction requires emergency veterinary care.

Do not get Mometamax in your pet's eyes, nose, or mouth.

Complete the prescribed course of treatment. Symptoms may clear up before the infection is fully treated.

Tell your veterinarian if your dog is pregnant or lactating.

Use of Mometamax on non-susceptible bacteria or fungi may result in overgrowth. Cease administration and seek a different treatment from your veterinarian.

Not for use in dogs with any condition that contraindicates corticosteroid use.

Do not use in working dogs such as seeing eye dogs, police dogs, or military dogs, as this medication may interfere with hearing.

Mometamax may cause hearing or vestibular impairment that is usually, but not always, temporary. If you notice such effects, discontinue use, flush the ear with water, and contact your veterinarian.

Consult your veterinarian before giving your pet any other supplement or drug, including other treatments for the ear infection, during a regimen of this medication.

Avoid concomitant use of drugs known to cause ototoxicity.

Gentamicin is not well-absorbed through the skin. However, prolonged application to large wounds, burns, or denuded skin can lead to ear or renal toxicity.

In dogs, diminished appetite, weight loss, ALP (SAP) and ALT (SGPT) enzyme elevations, excessive thirst, increased urination, lymphopenia, and neutrophilia have followed use of high-does, parenteral, or prolonged or systemic synthetic corticosteroids. In addition, canine Cushing's syndrome may occur with prolonged or repeated steroid therapy.

Ingestion can cause adverse effects, particularly due to this product's corticosteroid content. In the event of ingestion, contact your veterinarian.

If you know of or suspect an overdose, contact your veterinarian immediately.
