Always follow the dosage instructions provided by your veterinarian.

What should I discuss with my veterinarian while considering Mometamax?
Your veterinarian should examine your pet's ear to make sure the eardrum is intact.

Have your veterinarian or veterinary technician show you how to properly clean the ear and apply Mometamax.

Notify your veterinarian of any other medications or supplements your dog is taking, and if your dog has had any reactions to previous medications. Also, tell your veterinarian if your pet is pregnant or has any hearing loss.

What should I do if I miss a dose?
If you miss a dose, apply it as soon as you remember. If it is almost time for the next dose, skip the one you missed and go back to the regular schedule. Do not give two doses at once.

What is the most important information I should know?
The ear should be clean and dry before applying Mometamax. Mometamax should not be used in animals with perforated eardrums. Always follow your veterinarian's directions on the use of this medication.

Who should not take it?
Do not use in animals hypersensitive (allergic) to any of the ingredients. Do not use in animals who require their hearing to perform their work (military dogs, police dogs, seeing eye dogs, hearing dogs, etc.) as any hearing or vestibular (balance) impairment may not be reversible.

Do not use in pregnant animals unless benefits outweigh the risks.

What side effects may be seen when taking Mometamax?
May see loss of hearing or balance. If so, contact your veterinarian. These effects are usually temporary. If ingested, the most common side effect of corticosteroids is an increase in the amount of drinking and urinating.
