Penicillin Allergy — Who Should Be Tested and Why?
Wednesday, February 14, 2018
Think you are allergic to penicillin? It is important to correctly identify if you are not as unnecessarily avoiding penicillin leads to higher drug costs for patients and healthcare systems, limited and possibly inferior medical treatments, and possible antibiotic resistance.
What do you need to know:
-True penicillin allergy is serious, even life-threatening. Someone with a confirmed penicillin allergy should avoid the entire medication group which includes 15 chemically related drugs. Ask your physician if you should be prescribed injectable epinephrine, the only treatment that will stop anaphylaxis, a severe, potentially fatal, allergic reaction.
-A reaction to penicillin as a child does not automatically mean you will react as an adult. Penicillin allergy is not necessarily a life-long condition. Get tested to confirm.
-Symptoms of penicillin allergy may include hives, swelling of the mouth or throat, dizziness or difficulty breathing. Hives are often confused with skin rashes that are non-allergy related. Since it may be difficult to tell the difference, and you can’t always get to a doctor right away, take a photograph of the rash to help with the diagnosis.
-Alternative antibiotics to penicillin may be less effective in treating your infection, may cause unwanted side effects, or may be more expensive. Don’t limit your treatment options if it isn’t necessary.
-Penicillin allergy testing is safe and reliable. The patient undergoes a series of skin prick tests with gradually increased amounts of penicillin. A raised bump, or wheal, at the site of the prick, indicates the allergy. If the tests are negative, the next step is an oral challenge to confirm the patient can safely take this drug. These tests should always be conducted by a board-certified allergist trained to recognize and treat potential allergic reactions.
Penicillin Allergy testing is available at all 17 Atlanta Allergy & Asthma locations. For more information on Drug Allergies click here.
