Massachusetts residents who have been told that they are allergic to penicillin may actually be able to tolerate the drug. According to a study presented at a meeting held at the American College of Allergy, Asthma and Immunology, 90 percent of those diagnosed with such an allergy no longer have it. They may have either grown out of it or were misdiagnosed with the condition.
One doctor says that 25 million to 50 million Americans may believe that they have a penicillin allergy when they really don't. This doctor says that children may get an infection and then experience a rash or some other side effect while using penicillin. This may cause a doctor to incorrectly conclude that an allergy is present. Fortunately, it may be easy to determine if a person still has the allergy by giving him or her a low dose of the antibiotic.
