Penicillin, Drug or Vaccine Allergy


Skin testing can be performed to penicillin and other drugs to determine if a person is still allergic to that drug.  This is important information that can be shared with your doctors and pharmacy.


Penicillin is used to treat many different infections.  Being evaluated or being tested for an allergy to penicillin lets your doctors know whether it is safe to give you certain antibiotics.  There are many antibiotics that have penicillin in them or are similar to penicillin.  An allergy to penicillin means that even medications that are similar to penicillin can be dangerous and many times need to be avoided.


The most common signs of an allergy to penicillin are rash and itching.  A severe reaction could possibly be life-threatening and quite dangerous.  To evaluate you for a possible allergy when you come to Chicago Allergy & Asthma, we will first examine you and gather information to get a complete understand of what type of allergy you may have.  The doctor might think about having you undergo tests to see if penicillin is in fact an allergic trigger for you.


Depending on the results of your tests, you may be eligible to have treatment to see if you can safely take penicllin again.  We will closely observe you through this process and ensure that it is done in a safe manner with the expertise of our board certified allergy and immunology group.
