Penicillin Allergy Testing

Did your Mom tell you that you were ALLERGIC to PENICILLIN?

Nearly everyone knows someone who says they are allergic to penicillin. Up to 10 percent of people report being allergic to this widely used class of antibiotic, making it the most commonly reported drug allergy. Over time, however, the vast majority of people who once had an allergic reaction to penicillin lose sensitivity and can be treated safely with the drug (although 10 percent of individuals will remain allergic). Studies show that up to 90% of patients are found to be skin test negative, or not truly allergic.  

Understanding penicillin allergies is important for a variety of reasons. For certain conditions, penicillin is the best (or only proven) therapy. Some patients need penicillin because they are allergic to other types of antibiotics. Penicillin is, also, a very inexpensive drug and may cut your prescription costs by up to 60%.  To establish more complete medical histories and expand treatment options, your primary care physician may want to know if a childhood allergic reaction persists in their adult patients.  

Chicagoland Allergy & Asthma can help you evaluate the safety of taking penicillin. 

In addition to assessing your detailed history about a prior allergic reaction to penicillin, we can administer skin tests to determine if a patient is or remains allergic to the medication. These tests, which are conducted in our office, typically take about one to two hours, including the time needed after testing to watch for reactions.  The test is easy and safe with results known at its completion.
