DRUG ALLERGY Q & A

​

What is a drug allergy?

A drug allergy occurs when your immune system mistakenly identifies a medication as harmful and mounts a response. This can trigger symptoms that vary in severity, from mild skin reactions to severe systemic reactions, including anaphylaxis.

​

What are the symptoms of a drug allergy?

Symptoms can differ depending on the type of reaction and the individual, but may include:​

• Skin rashes, hives, or itching

• Swelling of the lips, tongue, or face

• Fever or joint pain

• Severe symptoms such as difficulty breathing, wheezing, vomiting, diarrhea, or collapse — these may indicate anaphylaxis and require immediate emergency care.

 

What causes drug allergies?

Drug allergies occur when your immune system reacts to a medication.

 

Common culprits include:

• Antibiotics (such as penicillin or sulfa drugs)

• Non-steroidal anti-inflammatory drugs (NSAIDs, e.g., ibuprofen, aspirin)

• Certain chemotherapy or biologic medications

It’s important to note that side effects or non-allergic reactions are different from true drug allergies.

How are drug allergies treated?

Treatment depends on the severity of the reaction:

• Mild reactions may respond to antihistamines or topical treatments to relieve itching and rash.

• Moderate to severe reactions may require corticosteroids or other prescription medications.

• Severe reactions or anaphylaxis require immediate treatment with an epinephrine auto-injector and emergency medical care.

 

Avoiding the offending drug and having a clear management plan with your allergist is essential to preventing future reactions. The allergists at Allergy and Asthma Specialists of Greater Washington provide individualized evaluation and guidance to help you safely manage your medications.
