Testing recommended

Allergic to penicillin?

If you’ve been told you have a penicillin allergy, you're not alone. About 10% of the population reports a penicillin allergy, but less than 1% of the whole population is truly allergic. The best way to know for sure is to be tested by one of our allergists.
