A member asked:

What are the side effects of sulfamethoxazole-tmp--am i allergic to cephalexin?

A doctor has provided 1 answer

Allergenic: Tmp (bactrim, septra, (sulfamethoxazole and trimethoprim) etc.) has a sulfonamide as one component. These are among the most allergy creating drugs known and anyone who is developing an allergy to other classes of drugs, like cephalosporins, has a higher risk of also being allergic to sulfa. Be careful !
