When to seek medical advice

By Mayo Clinic staff

Talk to your doctor if you think you're allergic to penicillin or if you experience any signs or symptoms of penicillin allergy. If possible, see your doctor when the allergic reaction is occurring. This will aid in making a diagnosis.

Seek emergency medical treatment if you develop any signs or symptoms of anaphylaxis.
