According to WebMD, SMZ-TMP DS is the abbreviation for a combination of two antibiotics: sulfamethoxazole and trimethoprim (Septra, Bactrim). The drug is used to treat a host of bacterial infections, including urinary tract, middle ear, respiratory and gastrointestinal infections. Additionally, it is given to some individuals to prevent Pneumocystis carinii pneumonia, a type of infection that is common in individuals with weakened immune systems, such as those with HIV.
