Taking action to be evaluated for a penicillin allergy can impact your health, safety and wallet. According to the Centers for Disease Control and Prevention, 10% of the U.S. population reports a penicillin allergy, but less than 1% is allergic after testing. Common penicillins include ampicillin, amoxicillin and Augmentin.
Penicillin allergy is an abnormal reaction of your immune system to the antibiotic drug prescribed for treating various bacterial infections. These medications are used often to treat ear infections, strep throat, sinus infections and to prevent dental infections.
Common signs and symptoms of an allergic reaction can include skin redness, itching, rash or swelling. These symptoms can occur for other reasons. Some symptoms, such as nausea, vomiting or diarrhea, are common when taking antibiotics. They frequently are misdiagnosed as an allergy.
