A member asked:

I have cellulitis. taking bactrim (sulfamethoxazole and trimethoprim) and keflex. is it necessary to take both? do they cancel each other out?

A doctor has provided 1 answer

No: They don't cancel each other out. There are times when we feel it is necessary to use 2 antibiotics from 2 different classes (such as Bactrim (sulfamethoxazole and trimethoprim) and Keflex) to cover the infection. I would continue both as your doctor prescribed.
