Ultimate Guide to Tresaderm

Meet the Pet Dermatological Solution: Tresaderm!

Tresaderm is an FDA-approved, veterinarian-recommended, pet antimicrobial medication that is used to treat bacterial, fungal, and inflammatory skin and ear conditions but is most well known as a top ear mite treatment. Tresaderm is a daily, topical drop solution that can eliminate the infection in only one week!

How does the Tresaderm solution work?

Tresaderm is a topical skin and ear medication with three active ingredients - Thiabendazole, Dexamethasone, Neomycin Sulfate solution. Thiabendazole is a fungicide (i.e., eliminates fungal infections and diseases) and a parasiticide that inhibits parasites, such as ear mites.

Dexamethasone is an anti-inflammatory corticosteroid that manages and treats dermatologic conditions. Neomycin Sulfate is an aminoglycoside antibiotic. These types of antibiotics enter the bacterial cell wall, inhibit the function of protein synthesis, and cause bacteria cell death. This stops bacterial growth.

How is the Tresaderm solution administered?

Tresaderm is administered topically once or twice a day on the skin or within the ears of dogs or cats directly to the infected area. For skin infections, 2 to 4 drops are applied twice a day to every square inch of the infected area for a week. For ear infections, apply 5 to 15 Tresaderm ear drops directly into the ear once a day for a week.

Your licensed veterinarian will offer a specific Tresaderm dosage schedule according to your pet 's needs and the severity of the infection. Improvement is observed between one to two hours, and the infection should be eradicated within one week.

What are the precautions of which you should be aware?

Inform your veterinarian of all antibiotics, antifungal, or corticosteroid medications and all supplements that your pets are taking. Tresaderm may have a negative interaction with some medications. Never give Tresaderm concurrently with non-steroidal anti-inflammatory drugs (NSAIDs).

Do not give Tresaderm to pregnant pets. Do not give Tresaderm to one with a ruptured eardrum.

Tresaderm solution should only be used for external use ONLY.Though Tresaderm is useful for deworming and treating fungal infections in the nasal cavity, Tresaderm has dangerous side effects (i.e., don 't use Tresaderm in your pet 's nasal cavity). Do not get Tresaderm in your or their eyes.

Tresaderm is ineffective against viral infections.

Tresaderm should not be used for more than a week.

Ensure that Tresaderm should be refrigerated.

What are the Tresaderm side effects of which you should be aware?

Tresaderm 's most common adverse reactions are polydipsia, vomiting, and diarrhea. Acute overexposure of Thiabenzadol may cause dizziness, anorexia, and nausea. If the pet shows sensitivity to Neomycin (or Neomycin Sulfate) by skin swelling, irritation, or redness around the infected area, discontinue use and contact your veterinarian.
