Drug Allergy
A drug allergy is the abnormal reaction of your immune system to a medication. Any medication — over-the-counter, prescription or herbal supplement can cause an allergic reaction.
Drugs commonly linked to allergies include:
-
Antibiotics, such as penicillin
-
Pain-relievers, such as aspirin, ibuprofen (Advil, Motrin IB) and naproxen sodium (Aleve)
-
Chemotherapy drugs for treating cancer
-
Medications for autoimmune diseases, such as rheumatoid arthritis
Symptoms include:
-
Skin rash
-
Hives
-
Itching
-
Fever
-
Swelling
-
Shortness of breath, wheezing
-
Runny nose, itchy, watery eyes
-
Anaphylaxis - a rare, life-threatening reaction to a drug allergy
Signs and symptoms of a serious drug allergy often occur within an hour after taking a drug. Other reactions, particularly rashes, can occur hours, days or weeks later.
Prevention
If you have a drug allergy, the best prevention is to avoid the problem drug.
Steps you can take to protect yourself include the following:
Inform health care workers. Be sure that your drug allergy is clearly identified in your medical records. Wear a medical alert bracelet that identifies your drug allergy.
