Drug Allergy Q & A

What is a drug allergy?

Allergies occur when your immune system overreacts to a substance it considers harmful, even though for most people it’s not. A drug allergy occurs when your immune system has an abnormal reaction to a medication or a substance in a medication. 

You can develop a drug allergy to any medication. However, the most common medications that cause an allergic reaction include:

  • Penicillin
  • Antibiotics containing sulfonamides
  • Aspirin
  • Nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Chemotherapy drugs
  • Anti-convulsants

You may be at greater risk of developing a drug allergy if you have other allergies or a family history of a drug allergy. Prolonged use of a medication may also lead to a drug allergy. 

What are drug allergy symptoms?

Drug allergy symptoms vary in type and severity. If you have a severe drug allergy, you may develop symptoms within an hour of taking the medication. With a less severe allergy, symptoms may not appear until hours, days, or even weeks later.

Signs and symptoms of a drug allergy include:

  • Hives
  • Rash
  • Itching
  • Fever
  • Shortness of breath
  • Angioedema
  • Wheezing
  • Runny nose
  • Watery eyes

A drug allergy may also cause anaphylaxis, a life-threatening allergic reaction that causes your body to go into a state of shock. Symptoms of anaphylaxis may include low blood pressure, difficulty breathing, or loss of consciousness. 

You need emergency medical care if you’re having an anaphylactic reaction to a drug. 

If you’re experiencing allergy symptoms and you suspect a drug allergy, the experts at Allergy Associates & Asthma, Ltd. can provide the answers you need. 

What can I expect during a drug allergy consultation?

When you visit Allergy Associates & Asthma, Ltd. for a drug allergy consultation, you can expect a thorough evaluation. All new patient appointments take 2-3 hours, which allows your provider an opportunity to develop the best solution.

In addition to a complete history and physical, the team may also run advanced allergy testing to identify the allergen responsible for your symptoms. 

How is a drug allergy treated?

The team at Allergy Associates & Asthma, Ltd. develops individualized drug allergy treatment plans based on the severity of your symptoms and whether the medication causing your allergic reaction is medically necessary.

To manage symptoms, the team may recommend:

  • Discontinuation of the drug
  • Antihistamines
  • Corticosteroids
  • Epinephrine pen (for anaphylaxis)

When possible, you should avoid taking the medication that causes a drug allergy. However, if the drug is medically necessary and your drug allergy symptoms are mild, the team may suggest a drug challenge, or drug desensitization, program.
