A member asked:
Which antibiotics are not sulfa based?
A doctor has provided 1 answer
Sulfa antibiotics: These days most antibiotics are not sulfa based. For the record, it was a sulfa antibiotic that was the first antibiotic to be available, back in 1932. Since then most antibiotics have not been sulfa-based. The main oral one currently in use in the us is sulfamethoxizole, commonly trade named bactrim, (sulfamethoxazole and trimethoprim) and is compounded with trimethoprim. There are also some eye drops that are sulfa-based.
