What causes drug allergies?

Medications can cause interactions, side effects, and allergies. Interactions occur when a medication doesn’t have the expected effect because another drug, food, or supplement changes the way it works. Side effects refer to unexpected symptoms caused by a medication.

Drug allergies are different. They develop when your immune system overreacts to the medication, releasing chemicals that cause symptoms.

Any medication may cause an allergy, but the most common are antibiotics (penicillin, amoxicillin, sulfa and others).

Antibiotics (penicillin, amoxicillin, tetracycline, and others)
Nonsteroidal anti-inflammatory drugs (NSAIDs)
Anti-seizure drugs
ACE inhibitors
Monoclonal antibodies
Chemotherapy medications

You’re more likely to have an allergic reaction to a medication you took in the past.

What symptoms do drug allergies cause?

Drug allergies cause symptoms that typically occur in hours or up to two weeks. In some cases, you may develop a skin rash up to six weeks after starting the medication.

Your symptoms may include:

Hives
Skin rash
Fever
Cough
Sneezing
Runny or congested nose
Itchy, watery eyes
Nausea and vomiting
Diarrhea
Headaches

Medications can also cause anaphylaxis, a severe allergic reaction that can put your life at risk. The symptoms usually appear within one hour.

Anaphylaxis may cause hives and swelling of your lips, tongue, and throat, followed by difficulty breathing, dizziness, fainting, and, worst case, shock, and death. You should immediately call 911 for emergency medical care.

How are drug allergies treated?

Allergy & Asthma Institute of Southeast Michigan specializes in individualized drug allergy care, beginning with allergy testing to determine the exact source of your symptoms.

Your provider may prescribe antihistamines or steroids to improve your symptoms, but the primary treatment for a drug allergy is to stop taking the medication. If you need the medication and your doctor can’t recommend a suitable alternative, you may need desensitization.

Desensitization decreases your allergic reaction by exposing your immune system to the medication. Your provider begins desensitization by giving you a tiny amount of the medication.

Then they give you another dose at specific intervals, gradually increasing the amount in the dose each time until you reach the full dose. Once your immune system becomes tolerant, you must keep taking the drug. As soon as you stop, your allergy returns.
