Important information about Otomax
The active ingredient in Otomax is a combination of gentamicin sulfate, clotrimazole, and betamethasone valerate.
Gentamicin sulfate is a broad-spectrum antibacterial agent that works by stopping bacterial growth. Clotrimazole is an antifungal agent that helps treat fungal infections by damaging the fungal cell membrane. Betamethasone valerate is a corticosteroid with anti-inflammatory effects that reduces redness, swelling, itching, and irritation in the external ear canal. Together, these active ingredients help relieve discomfort and improve healing during ear infections.
Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Otomax. However, the following is a synopsis of the general guidelines for the use of Otomax:
- Use Otomax exactly as directed by a licensed veterinarian.
- Clean and dry the affected ear before applying the otic ointment.
- Shake the medication well before use if instructed.
- Apply the prescribed amount into the external ear canal.
- Gently massage the ear after application to help spread the medication.
- Avoid touching the applicator tip to the ear or other surfaces.
- Wash your hands after applying the medication.
- Use Otomax for the full number of consecutive days prescribed, even if symptoms improve earlier.
- Avoid use if there is a known perforation of the eardrums unless advised by a veterinarian.
- Keep the medication away from the reach of children and pets.
Some mild or common side effects of Otomax include:
- Mild irritation in the ear.
- Redness or itching at the application site.
- Temporary discomfort after dosing.
- Increased ear sensitivity.
- Mild head tilt.
Some individuals may experience serious side effects while using Otomax. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:
- Hearing loss or changes in hearing.
- Severe hypersensitivity or allergic reaction.
- Swelling of the face or severe ear inflammation.
- Worsening infection or discharge from the ear.
- Balance problems or severe head tilt.
- Skin thinning from prolonged corticosteroid use.
These are not all of the possible side effects of Otomax. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.
Before starting Otomax, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including if you have:
- A known perforation of eardrums.
- Chronic ear infections or repeated otitis externa.
- Known hypersensitivity to gentamicin sulfate, clotrimazole, or corticosteroids.
- Existing hearing loss or balance problems.
- Fungal infections that have not been properly diagnosed.
- Use of other antimicrobial or steroid medications.
Additional precautions include:
- Prolonged use of corticosteroid-containing medications may delay wound healing.
- Overuse of antimicrobial products may increase the risk of resistant infections.
- Stop use and contact your veterinarian if symptoms worsen.
- Monitor for signs of allergic reaction or irritation during treatment.
Otomax should not be used in animals with known hypersensitivity to gentamicin sulfate, clotrimazole, betamethasone valerate, or other corticosteroid ingredients. It should also not be used in animals with perforation of the eardrums.
Many pets begin to show improvement within several days of starting Otomax. Full improvement of bacterial or fungal infections may take the complete treatment course recommended by the veterinarian.
When Otomax is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that your dog is taking, including dewormers, to avoid any negative drug interactions, including:
- Other otic medications, because combining treatments may increase irritation or reduce effectiveness.
- Corticosteroid medications, because combined steroid exposure may increase side effects.
- Antimicrobial medications, because overlapping antibacterial or antifungal therapy may affect treatment response.
- Supplements or ear cleansers not approved by your veterinarian.
Otomax is available as an otic ointment that is typically dosed depending on the size of the animal and severity of the ear infection:
Small dogs usually receive 4 drops into the affected ear once or twice daily.
Larger dogs may require 8 drops into the affected ear once or twice daily.
Treatment duration is commonly 7 consecutive days, but dosing may vary depending on the infection and the veterinarian's instructions.
Store Otomax at room temperature away from excessive heat and moisture. Keep the container tightly closed and out of reach of children and pets.
Otomax is manufactured by Merck Animal Health.
Yes. Generic versions containing gentamicin sulfate, clotrimazole, and betamethasone valerate may be available.
Do not stop using Otomax before the full treatment course is completed unless directed by your veterinarian. Stopping treatment too early may allow the infection to return or worsen.
The safety of Otomax during pregnancy has not been fully established. Use during pregnancy should only occur if recommended by a veterinarian.
It is not fully known whether the active ingredients pass into breast milk in animals. Consult a licensed veterinarian before use during breastfeeding or nursing.
