　　Have you been told you have penicillin allergy? Did your parents tell you that you had a reaction as an infant or child, so you should never take it again? Has it been so long since you had a reaction to penicillin that you don't remember what happened? If you fit any of these descriptions or are just not sure if you have penicillin allergy, there's good news for you: Chances are, you probably don't have it.

　　Between 10 to 20 percent of Americans believe they have a penicillin allergy, but a recent study at Mayo Clinic found that only 10 percent of those people are truly penicillin allergic. In other words, 9 out of 10 people who think they have penicillin allergy are avoiding it for no reason. Even in people with documented allergy to penicillin, only about 20 percent are still allergic 10 years after their initial allergic reaction. It's not necessarily a permanent condition.

　　Why is this important? Aren't there many other antibiotics you can use if you have penicillin allergy? Penicillin has been around since 1928. Penicillin and its related medicines include amoxicillin, methicillin and amoxicillin-clavulnate. These medicines are highly effective treatments for many bacterial infections, such as strep throat and ear infections. Of course, there are alternative antibiotics, but these are often much more expensive and carry a higher risk of side effects. Typically, these alternative antibiotics are broad-spectrum, meaning they fight many types of bacteria, both good and bad. That can lead to development of drug-resistant bacteria, or deadly "superbugs". This increases the risk for all of us in the future of not having an effective antibiotic to treat our infection.

How do you find out if you have penicillin allergy? Board-certified allergists can test you.
