Medication and Drug Allergies

Medications are an important part of curing and controlling illness, however, all medications have the potential to cause side effects that can range from mild to life-threatening. It is important to take medications exactly as they are prescribed, and to discuss with your prescribing provider if you experience side effects.

According to the American Academy of Allergy, Asthma, and Immunology, approximately 5-10% of adverse reactions to medications are allergic reactions. Allergic reactions to medication usually occur within moments to a few hours of taking the drug. Symptoms can occur in the nose, lungs, throat, sinuses, ears, lining of the stomach, or the skin. While any medication can cause an allergic reaction, some familiar medications that can cause allergic reactions include antibiotics such as penicillin, sulfa drugs, insulin, and chemotherapy drugs.

What is the most common allergic reaction to medications?

The most common allergic reaction results in itchy eruptions that occur days to weeks after taking the medication. Some skin eruptions can develop up to six weeks after starting certain medications.

What are common non-allergic reactions to medications?

Non-allergic reactions to medications are much more common than allergic reactions. These reactions depend on the medications involved. Patients experiencing side effects should speak to their prescribing provider or seek immediate medical attention.

When should I see an allergist/immunologist?
