A member asked:

What would doctors prescribe a patient who is allergic to penicillin?

A doctor has provided 1 answer

Depends: There are alternative antibiotics to penicillin-type antibiotics. The choice depends on the infection being treated. There is testing available for penicillin allergy. Those with penicillin allergy should see a board certified allergist for further evaluation.
