Your Thorough Guide To Mometamax For Dogs And Cats

What Is Mometamax for Cats and Dogs?

Ear infections are quite common in pets. As pet parents, we've seen the familiar signs of our cats and dogs shaking their heads and scratching their ears. These ear infections are typically yeast or bacterial. The condition is called otitis, and treating it can be as simple as using Mometamax Otic Suspension!

What Is Otitis in Dogs and Cats?

When your cat or dog has excessive bacteria or yeast in their ear canals, it causes otitis, a common ear infection. Bacteria and yeast overgrowth can have root causes in many things, from allergies to broken skin inside the ear. When your dog or cat has allergies, the skin inside their ears can become inflamed and irritated.

Their skin defenses are weakened, leading to an overgrowth of yeast in their ears. This can lead to scratching, which breaks the skin and allows bacteria to take hold. Additionally, water can get inside your pet's ear by accident during baths or even walking in the rain.

This creates a perfect environment for bacteria and yeast as it is a dark, moist, and warm place. Otitis is caused by growths, like tumors or polyps, in your cat or dog's ear. These growths allow ear wax to build up in the ear canal and can harbor bacteria in the debris that piles up.

What Are the Symptoms of an Ear Infection?

If your dog or cat has an ear infection, the first sign is usually excessive scratching and fussing with their ears. They might rub their ears on the ground as well, trying to scratch them, and they can whine or cry while scratching their ears. Additionally, if you examine their ears, you might notice yellow or brown debris with a waxy texture.

Your cat or dog's ear will smell noticeably bad. Often, in the advanced stages of the infection, you can smell the foul odor when they come into the room. If the ear infection gets bad enough, there is the risk of extreme swelling in your pet's ear, closing the ear canal.

Chronic ear infections can lead to a hardening of the ear canal and can even lead to hearing loss. If your dog has large ear flaps or has a lot of hair around their ears, they may be more prone to ear infections than dogs with perky ears and short hair. As a cat owner, you should keep an eye out for ear mites.

How Does Mometamax for Dogs and Cats Help?

Mometamax for cats and dogs is a simple suspension of gentamicin sulfate, mometasone furoate monohydrate, and clotrimazole. Gentamicin sulfate is a broad-spectrum antibiotic that is exceptionally effective when used topically to treat bacterial infections.

Mometasone furoate monohydrate is a corticosteroid of medium strength. This drug is used to soothe your pet's ears and give relief from the redness, swelling, and itchiness that they are experiencing. Finally, clotrimazole is an antifungal agent used to treat a broad spectrum of candidiasis or yeast infections.


he combination of these drugs is used to target yeast infections caused by Malassezia pachydermatis and bacterial infections caused by Pseudomonas, coagulase-positive staphylococci, beta-hemolytic streptococci, Enterococcus faecalis, and Proteus mirabilis.

What Is the Mometamax Dosage I Should Give My Pet?

Mometamax Otic Suspension is available in 7.5 g, 15 g, 30 g, and 215 g bottles. The dosages of medicines in the bottle are pre-formulated, so you don't have to worry about the exact dosage of the drugs themselves. You can use the following dosage guidelines:

Your Pet's Weight Number of Drops To Use
Less than 30 lbs Four drops per ear
Equal to or more than 30 lbs Eight drops per ear

For maximum efficiency, use this daily for at least seven days, or however long your vet has asked you to. These are general guidelines. You should ask your vet for specific treatment protocols for your cat or dog after examination, depending on the severity of the infection.

Are There Any Mometamax Side Effects or Precautions I Should Take?

When you're using Mometamax Otic Suspension, you should note if your pet shows any exaggerated signs of discomfort. Pets usually show distress when using ear drops, but keep an eye out for signs of allergic reactions like excessive scratching and swelling. Additionally, you should not use this medicine on pets who have tympanic perforations.

If your cat or dog loses hearing, develops balancing problems, has increased thirst and urine output, you should contact your vet. You should contact your vet if your pet's weight increases after starting this medicine, they get chronic diarrhea, and are frequently vomiting.

  3. How Fast Does This Medicine Take to Work?

    Mometamax for dogs and cats should start to show results in as little as seven days. However, it can take longer to show improvement depending on the severity of the infection, your cat or dog's overall health, and the type of condition under treatment.

Mometamax Knocks Out Yeast!

I would have rated higher for ease of use, but the label does not indicate whether the product can be warmed before applying to the ear. My dog (a Dogo Argentino) does not like anything placed in her ears but is more tolerant if the product isn't cold. (I don't know anyone who likes a shot of anything cold in their ears.) Having this information would have been helpful. Other than that I am very satisfied. I paid half as much for twice the amount I got from our Vet.

Best price I could find.

One of my dogs has chronic ear infections, and we put in this product 2X a week for prevention. I bought two bottles for a few bucks more than one at the vet or other online stores.

Mometamax works

Mometamax is a prescription medicine for ear fungus infections in dogs. Initially a different vet prescription which did not clear up my dogs ear infection. My current veterinarian prescribed "Mometamax" and oral medicine and the ear infection started to clear up. Because the ear infection was not completed gone my vet prescribed another bottle of Mometamax. I looked online for a better deal and found Mometamax at found double the size for about the same price my veterinarian was charging at "PetCareRx"!!! PetCareRx even contacted my veterinarian for me to get the approval!After it was approved by my veterinarian for my dog, PetCareRx shipped the medicine to us immediately!I highly recommend checking the prices on PetCareRx for any medication you may need for your pets!

Works well, excellent value

My pug is often prescribed this for tendency to have skin and ear infections. And it was expensive! When I saw its price on this web site, I was shocked and very, very happy! Fortunately, my vet provided a prescription for a bigger container, so next time her skin is showing signs of irritation, I will be able to treat it much more quickly... and less costly!

Mometamax is great!

My chocolate Lab and Chessie have had chronic ear infections since they were puppies. Medication from their dr never seems to clear the problem up completely. This is the first time they seem to be symptom free. Used it for only 7 days instead of the 14 days required by their dr medication. Also like the fact that it is all in one and I don't have to put meds in their ears as well as an oral anti-biotic.
