SMZ/TMP (Sulfamethoxazole and Trimethoprim) is a broad-spectrum antibiotic designed to counter a variety of bacterial infections in multiple species. It fights against infections in the urinary tract, respiratory tract, gastrointestinal tract, skin, and much more. Since these conditions can lead to great pain and discomfort, it is important to identify the cause and get appropriate treatment right away. This is an oral antibiotic, and it can be mixed with food during feeding time.
