Drug Allergy and Desensitization Program

Additional Information

What to Expect During Your Visit

Some allergic reactions to drugs—particularly rashes, hives and asthma—can resemble certain diseases.

At your initial evaluation, our Allergy specialists will take a detailed history and perform a physical examination looking for signs of a drug reaction. We will need the following information:

  • What drug do you suspect caused your reaction?
  • When did you start taking the suspected medication, and have you stopped taking it?
  • How long after you took the drug did you notice symptoms, and what did you experience?
  • How long did your symptoms last, and what did you do to relieve them?
  • What other medications, both prescription and over-the-counter, do you take?
  • Do you also take herbal medications, vitamins or supplements? Which ones?
  • Have you had reactions to other drugs? What kind and when did they occur?

If you can, bring the suspected drug with you, as well as any pictures of any rash or other physical symptoms associated with the reaction.

If a drug allergy is suspected, our Allergy specialists may also recommend a skin test or a graded drug challenge, where you will be supervised by an Allergy specialist and trained medical staff as you take the drug suspected of triggering a reaction in a closely monitored setting. If your previous reaction was severe, the challenge may be performed in an intensive care unit.

Once your evaluation is completed, we will coordinate with your physicians to develop the best treatment plan for you.
