What is dexamethasone otic?
Dexamethasone otic is a topical steroid medication used to treat inflammation of the ears in pets, often with other medications such as antibiotics. There are no veterinary brands of dexamethasone otic.
It is used off label (extra label) in veterinary medicine. Many drugs are commonly prescribed for off-label use in veterinary medicine. “Off label” means the drug is being used in a way that has not been reviewed or approved by the U.S. Food and Drug Administration (FDA) or Health Canada. In these instances, follow your veterinarian’s directions and cautions carefully, as they may be significantly different from those on the label.
How do I give my pet dexamethasone otic?
- Dexamethasone otic comes as a liquid solution that is used topically in the ear canal of pets when prescribed by a veterinarian for this purpose.
- Follow your veterinarian’s directions for application and measure the liquid solution carefully.
- If you are also instructed to clean or flush your pet’s ear, ask your veterinarian whether to clean before or after giving otic medications.
- Wash your hands after applying.
- Do not handle this medication if you have a known sensitivity to dexamethasone or other drugs like it (e.g., prednisone).
This medication should take effect within 1 to 2 hours and improvement in clinical signs should follow.
What if I miss giving my pet the medication?
If you miss a dose, give it as soon as you remember, and then continue with the regular dosing schedule. However, if it is almost time for the next dose, skip the missed dose and resume the regular dosing schedule. Do not give the pet two doses at once.
Are there any potential side effects?
Dexamethasone otic may cause the following side effects:
- Redness or inflammation at the site of application.
Serious adverse reactions may occur. If any of the following signs develop, stop giving dexamethasone otic and contact your veterinarian immediately:
- Ear inflammation or infection that does not respond to treatment, does not appear to be healing, or is getting worse
- Worsening ear pain
- Vomiting, diarrhea, or loss of appetite
- Weight loss
- Development of sores in or around the mouth
- Increased thirst (i.e., frequent drinking of large quantities of water) and frequent urination.
- Thinning of the skin
- Progressive hair loss
- Increased skin tears
- Throat swelling or difficulty breathing (indicates a severe allergic reaction)
Drug sensitivities can develop over time, with repeated exposure. Your pet may have no reaction after the first few doses but may develop a sensitivity later. It is important to watch for signs of an allergic reaction over the entire course of treatment.
Other side effects may occur. If you notice anything unusual, contact your veterinarian immediately. This moderate-acting medication should stop working within a few days, although the effects can be longer in pets with liver or kidney disease.
Are there any risk factors for this medication?
DO NOT USE dexamethasone otic in:
- Pets that are allergic to it or drugs like it.
- Birds, as they are very sensitive to steroids
USE WITH CAUTION in:
- Pets that are diabetic
- Pets with renal disease
- Pets that are pregnant or nursing
Prolonged use of glucocorticoids such as dexamethasone, both orally and topically, can suppress the hypothalamic–pituitary axis (HPA) which may lead to the development of diseases of the pituitary and adrenal gland, such as Cushing’s disease (hyperadrenocorticism).
Are there any drug interactions I should be aware of?
Do not give other corticosteroids (e.g., prednisone) with dexamethasone otic unless instructed by your veterinarian.
There are no documented drug interactions for this medication. Be sure to tell your veterinarian about any medications (including vitamins, supplements, and herbal therapies) that your pet is taking before starting any treatment.
Is any monitoring needed with this medication?
- At home, monitor for any side effects such as those noted above. If any side effects occur, discontinue the medication and contact your veterinarian.
- If redness, irritation, or swelling persists or increases, discontinue use and consult a veterinarian.
- Your veterinarian will let you know when they want to reassess your pet to ensure the medication is working and not causing side effects.
How do I store dexamethasone otic?
- Store this medication in its original container, at room temperature of 68°F to 77°F (20°C to 25°C).

- Store compounded forms of this medication according to the label.
