Tresaderm aids in the treatment of certain bacterial, mycotic and inflammatory skin infections and otitis externa (ear infections) in dogs and cats. Both acute and chronic forms of these conditions respond to treatment with Tresaderm. Each ml of Tresaderm contains 40 mg thiabendazole, 1 mg dexamethasone and 3.2 mg neomycin. Prior to the administration of Tresaderm, remove the ceruminous, purulent or foreign materials from the ear canal, as well as the crust which may be associated with dermatoses affecting other parts of the body. Depending on the severity of the condition, 5 to 15 drops should be instilled in the ear twice daily. In treating dermatoses affecting other than the ear, the surface of the lesions should be well moistened (2 to 4 drops per square inch) with Tresaderm twice daily. The volume required will be dependent upon the size of the lesion. Application of Tresaderm should be limited to a period of not longer than one week. Thiabendazole, dexamethasone and neomycin.
