Major Uses

Sulfadimethoxine and ormetoprim are two antibiotic medications that are compounded into one drug to increase effectiveness and coverage. Sulfadimethoxine is a long-acting sulfonamide, and ormetoprim is a diaminopyrimidine. The medications work together to provide broad-spectrum antimicrobial activity. Sulfadimethoxine/ormetoprim is primarily used in dogs.

Sulfadimethoxine/ormetoprim is used in the treatment of skin, urinary tract, and wound infections caused by susceptible bacteria. The combination of medications is effective against multiple gram-positive bacteria, including most Staphylococci, most Streptococci, and Novardia. Susceptible gram-negative bacteria include Escherichia coli and most Enterobacteriaceae spp. Additionally, sulfadimethoxine/ormetoprim is an effective treatment for conditions caused by some intracellular parasites, including Toxoplasma gondii and Coccidian spp.
