Tresaderm is a prescription medication used to treat various skin infections and ear mite in dogs and cats. It heals fungal and bacterial infections in the ear and on the skin. In addition, it helps with the pain, swelling, and itch that often accompanies these infections.

Main Ingredients

Tresaderm contains three active ingredients.

  1. Thiabendazole for treating mites and worms that have caused an infection
  2. Dexamethasone, a steroid for calming itching and inflammation
  3. Neomycin sulfate, an antibiotic to heal bacterial and fungal infections

Medication Form

It is only available with a prescription and needs to be kept refrigerated. If you order it online, it should be shipped in packaging to keep it cold.

It is a liquid available in 7.5 ml and 15 ml dropper bottles.


Your vet will discuss the exact dose for your specific pet. Don’t use the medicine until you have spoken to your vet. Follow the directions exactly. Don’t skip treatments or give too much in one dose.

For treatment of ear mites and ear infections, treatment usually lasts for about a week, with anywhere from 5 to 15 drops in each ear.

For treatment of skin conditions, treatment also lasts about a week, with 2 to 4 drops per square inch of infected skin, applied 2 times a day.

The length of treatment depends on what your pet is being treated for and how quickly the condition responds to the drops.

Finish the entire treatment, even if your pet seems completely healed. Otherwise the condition may quickly return or the bacteria may built up resistance.


This liquid is generally safe as a topical antibiotic. It should not be used in the eyes or taken internally. Avoid having your pet lick the treated area. A cone can sometimes help if this is a persistent issue.

Don’t use it if you know your cat or dog is allergic to any of the ingredients.

Avoid using it if your pet is pregnant.

Other drugs may interact with Thiabendazole occasionally. Talk with your vet about any other medication your pet is taking.

Since dexamethasone is a steroid, there is a rare chance it could be absorbed through the skin and into the circulation if it is used long-term. This can lead to problems with adrenal glands. Using as directed for short term treatment should not cause this issue.

Frequently Asked Questions

What if my pet licks off the Tresaderm?

The medicine has a very bitter taste that discourages licking. But it is not toxic. However, if he licks it off, the medicine won’t be treating the infected area. Ideally the medicine should be left alone for at least 20 minutes after application.

It may be necessary to use a cone for 20 minutes or so to make sure the medicine can have its full effect.

If I have some drops left over, can I save them to use later?

It’s never a good idea to keep medicine around after you have finished treatment. For your family’s and pet’s safety, dispose of any unused medication properly.

If your pet develops skin infections again, it is best to consult the vet.

Using old medication may not help the new infection and may even build up resistance.
