Tresaderm contains thiabendazole which treats bacteria, ear mites and fungal infections of the skin caused by molds, but does not treat viruses. Tresaderm also contains neomycin, an antibiotic, which effectively treats a variety of bacteria, and the steroid, dexamethasone, which alleviates itching and reduces inflammation.
Precautions and Side Effects
Some dogs may have an allergic reaction to Tresaderm, although it is generally safe when used topically (rubbed onto the skin). It should not be used for any pregnant animal. Thiabendazole can interact with other medications, such as theophylline and aminophylline. A veterinarian should be informed of any other medications in use before prescribing Tresaderm. Since dexamethasone (a steroid) can be absorbed into the circulation system, chronic use can suppress the functioning of the adrenal glands.
Doses Depend Upon Use
Tresaderm can be administered from five to 15 drops for a dog ear infection of the ear canal for seven days. This can be supplemented by a dog ear wash. However, for skin conditions, only two to four drops per square inch treated twice daily for seven days, is needed. Monitoring is important to determine if there are any adverse reactions. The prescription should be exhausted even if the dog seems "cured," since a relapse or resistance can occur.
