Sulfamethoxazole and Trimethoprim Tablets for Dogs and Cats

Compare to the active ingredients in Bactrim DS

An oral broad-spectrum antibiotic used in dogs and cats to treat many infections as directed by your pet's veterinarian.

Resistance is a major concern when giving antibiotics. Resistance occurs when bacteria survive and mutate and are then able to survive even after antibiotics are given. To help avoid any resistance, it is important to give antibiotics as they are prescribed for as long as they are prescribed even if your pet is looking and feeling better.
