Ultimate Guide to Otomax Ointment

Meet the Ear Infection Healer: Otomax Ointment!

Otomax Ointment is a highly recommended dog ear infection medication with an antimicrobial and corticosteroid combination. The solution effectively treats chronic and acute bacterial or fungal infections that result in pain and inflammation outside the ear. Otomax Ointment has easy-to-use drops or ointment in the ear canal twice daily.

How does Otomax Ointment work?

Otomax Ointment is a medication with three active ingredients - Gentamicin, Betamethasone, and Clotrimazole.

Gentamicin (pharmaceutical name Gentamicin sulfate, USP) is a broad-spectrum antibiotic and bactericide that inhibits normal protein synthesis and the growth of Gram-positive and Gram-negative bacteria found on and within canines' ears, such as Pseudomonas, Proteus, E.coli, and Staphylococcus.

Betamethasone (pharmaceutical name Betamethasone Valerate, USP) is a highly effective and safe corticosteroid (i.e. steroidal ingredient) that has anti-itching and anti-inflammatory properties.

Clotrimazole (pharmaceutical name Clotrimazole, USP Ointment) is a broad-spectrum antifungal agent that treats dermal infections caused by pathogenic dermatophytes and yeasts. The primary action of Clotrimazole is a fungicidal concentration with microbiological properties that work against dividing cells and growing organisms.

Together, the Gentamicin-Betamethasone-Clotrimazole (the Otomax generic name) combination is an antimicrobial, antipruritic, and anti-inflammatory solution. The compatibility is an especially effective treatment against dogs' severely painful ear infections, such as acute or chronic otitis externa.

How is Otomax Ointment administered?

Otomax Ointment is administered with medicated drops (bottles) or ear ointment (tubes) into the dog's ear canal twice daily for seven consecutive days. The product is available in 7.5 g and 15 g tubes, as well as 15 g, 30 g, and 215 g bottles. Each gram of Otomax Ointment contains 3 mg Gentamicin, 1 mg Betamethasone, and 10 mg Clotrimazole.

Common medications for ear mites are anti-parasitic medications like Tresaderm and Fipronil, which are applied directly into the dog's ear canals.

What Is the Difference Between Otomax and Mometamax?

Otomax is a topical medication comprising gentamicin, clotrimazole, and betamethasone, which has been prevalent for years to treat ear infections. Mometamax is a more recent launch, which replaces betamethasone with mometasone furoate. The change makes Mometamax a single daily dosing medication as compared to twice a day. This makes Mometamax a better medication as it's easier on the pet.

Otomax is a veterinary medication, which has gentamicin, clotrimazole, and betamethasone. It's used to treat bacterial and yeast infections of the outer ear in dogs and off-label in cats.

The medication itself is clotrimazole, which is sold under the brand name Otomax. Some of the generic alternatives include DVMax and Otibiotic. Another recent product is Mometamax, which is a one-time daily application and pet-friendly.

Can Otomax Be Used for Dermatitis?

Viruses, bacteria, or fungi cause dermatitis. The chemical composition of Otomax makes it anti-bacterial and anti-fungal. For this reason, some veterinarians may prescribe Otomax for Dermatitis. However, that's not the intended use for the medication, and it should be used only to treat external ear infections in dogs and cats, as prescribed by a vet.

What Is the Brown Stuff in My Dog's Ears?

If your dog has a waxy, yellow, or brown ear discharge, it's a sign of an ear infection. The infection can be caused by multiple reasons like allergies, excessive ear wax, polyps, mites, and swimming. If the brown discharge is followed by head shaking, rubbing ears, foul odor, and itching, it's 100 percent ear infection, and you should pay a visit to your doctor.

How Can I Treat My Dogs' Ear Infection Without Going to the Vet?

There are several home remedies for ear infections. One of the most popular remedies is apple cider and distilled water in a 1:1 solution. The pet parent should then put this solution into the ear with a long syringe or solution bottle. The solution should be in the ear canal for several minutes before your dog shakes it out. To make sure the solution stays in and does its job, put cotton balls in the ear and calm the dog.

However, home remedies such as this might not work in case of severe infection, and medication like Otomax is the order of the day. If your dog is still discharging dark brown stuff with a foul odor and itching its ear after using apple cider and water solution, a vet visit is a must.

What Happens if Dog Ear Infection Goes Untreated?

Ear infections are pretty painful and make your dog suffer. It doesn't go away on its own and, if left untreated, can be disastrous for your dog's health. Serious infections are known to rupture the eardrum and cause permanent hearing loss as well. Therefore, as soon as you see signs of ear infection in your dog, it's a must to visit a veterinarian.

Smaller dogs (under 30lbs) need four drops from the 7.5g tube, 15g tube, 15g bottle, and 30g bottle, which is doubled for bigger dogs (above 30lbs).
