Lifestyle and home remedies
By Mayo Clinic staffIf you think you've had reactions to penicillin in the past, be sure to tell your doctor and other medical professionals, including your dentist. Let your doctor know about any new reactions you notice when taking your medication. If your doctor determines that you're allergic to penicillin, it's a good idea to wear a medical alert bracelet that describes your allergy. You might also want to carry an alert card in your wallet or purse. These items are available over-the-counter at most drugstores or can be purchased on the Internet.
