Drug Allergy and Intolerances

A drug allergy is caused by an immune response to a particular medication.  Some drug allergies carry a risk of "allergic shock" or anaphylaxis if the medication is taken again.  There are other types of immune reactions that carry different risks.  Skin rashes are common in many types of drug allergies. It is extremely important to know which drugs cause these reactions and there are tests to determine your risk.
