Parasitic infection: Cannot imagine what parasitic infection is likely to respond to therapy with Bactrim (sulfamethoxazole and trimethoprim). You really need to be seen and discuss this with a doctor who can have access to your records and examine you. Preferably an infectious diseases expert. Good luck.

Parasite infection: Bactrim (sulfamethoxazole and trimethoprim) is an antibiotic which means its chief effect is on bacteria, not parasites. That said, Bactrim (sulfamethoxazole and trimethoprim) does work for cyclospora and isospora- parasites that cause diarrhea. It doesn't make sense that your symptoms return after a treatment course- unless you are getting re-exposed somehow in your environment or something "unrelated" to these purported parasites is occurring. Best to go see an MD.
