Cellulitis. Prescription 2 antibiotics-keflex 4x day /7days & bactrim (sulfamethoxazole and trimethoprim) 2x day/7 days. After 2 days, had bad side fx-doc says stop keflex only. Is this a concern?

YES. You do not indicate what the reaction was that prompted a change in therapy, but if this was an allergic reaction it was far more likely to have been due to the Bactrim (sulfamethoxazole and trimethoprim) which contains a sulfonamide. Read more...
Antibiotic choice . I would be unable to answer this appropriately. Of course, you could have reacted to either antibiotic. Of course, the physician may already know what bacteria you have and made a choice to change your antibiotic. Careful followup and communication are most important for you over the next week. Did your symptoms improve with the removal of the bactrim (sulfamethoxazole and trimethoprim)? Read more...

I went to the ER Monday night and was told I had a bad case of cellulitis. How many days should the bactrim (sulfamethoxazole and trimethoprim) take to stop the stinging?

Treat until better. Sometimes the pain and inflammation of cellulitis takes a few days to go down. That's because of the injury the bacteria have caused.

Try to elevate the area (or stay off it) to help ease the pain. Read more...
