What happens during a skin test for penicillin allergy?

ANSWER

First, your doctor will use a tiny needle to prick your forearm and give you a weak dose of penicillin. If you have an allergy, you’ll get an itchy red bump in about 15 minutes.

If you don’t get a bump, you'll get a dose of penicillin under the skin of your forearm. Again, if you get a bump within 15 minutes, you are allergic.

Just to be sure, your doctor might give you a regular dose of penicillin by mouth. You’ll stay in the office for about an hour.
