I need to know if bactrim has penicillin in it. Does it?
30 Apr 2011
No, Bactrim does not contain any penicillin.
Bactrim (Co-trimoxazole) contains a combination of sulfamethoxazole and trimethoprim and is supplied in tablets and a liquid suspension. Sulfamethoxazole and trimethoprim are both antibiotics that treat different types of infection caused by bacteria.
Bactrim is used to treat ear infections, urinary tract infections, bronchitis, traveler's diarrhea, and Pneumocystis carinii pneumonia.
For people who are allergic to penicillin it is considered safe to take Co-trimoxazole.
