What is an adverse drug reaction?
An adverse drug reaction is a harmful reaction to a medicine given at the correct dose. The reaction can start soon after you take the medicine, or up to 2 weeks after you stop.

How is an adverse drug reaction diagnosed?
Your healthcare provider will ask about your medical history and allergies. You may need additional testing if you developed anaphylaxis after you were exposed to a trigger and then exercised. This is called exercise-induced anaphylaxis. Medicines can be a trigger. You may also need any of the following:
What steps do I need to take for signs or symptoms of anaphylaxis?
Immediately give 1 shot of epinephrine only into the outer thigh muscle.
What safety precautions do I need to take if I am at risk for anaphylaxis?
Keep 2 shots of epinephrine with you at all times. You may need a second shot, because epinephrine only works for about 20 minutes and symptoms may return. Your healthcare provider can show you and family members how to give the shot. Check the expiration date every month and replace it before it expires.
Call 911 for signs or symptoms of anaphylaxis,
such as trouble breathing, swelling in your mouth or throat, or wheezing. You may also have itching, a rash, hives, or feel like you are going to faint.

What is a drug reaction?
Drug reactions encompass all adverse events related to drug administration, regardless of etiology. Drug hypersensitivity is defined as an immune-mediated response to a drug agent in a sensitized patient. Drug allergy is restricted specifically to a reaction mediated by IgE.
What are the complicating factors of drug reactions?
Complicating factors of drug reactions include the myriad clinical symptoms and multiple mechanisms of drug-host interaction, many of which are poorly understood. In addition, the relative paucity of laboratory testing that is available for drug allergy makes the diagnosis dependent on clinical findings.
What is drug hypersensitivity?
Drug hypersensitivity results from interactions between a pharmacologic agent and the human immune system. These types of reactions constitute only a small subset of all adverse drug reactions. Allergic reactions to medications represent a specific class of drug hypersensitivity reactions mediated by IgE. Immune-mediated drug reactions may be ...
What percentage of drug reactions are nonimmunologic?
Drug reactions can be classified into immunologic and nonimmunologic etiologies ( Table 1). The majority (75 to 80 percent) of adverse drug reactions are caused by predictable, nonimmunologic effects. 1 The remaining 20 to 25 percent of adverse drug events are caused by unpredictable effects that may or may not be immune mediated. 1 Immune-mediated reactions account for 5 to 10 percent of all drug reactions and constitute true drug hypersensitivity, with IgE-mediated drug allergies falling into this category. 2, 3
What classification system is used to describe immune-mediated drug reactions?
Immune-mediated drug reactions may be discussed generally in the Gell and Coombs classification system, a widely accepted conceptual framework for understanding complex immune reactions. However, some reactions involve additional, poorly understood mechanisms that are not easily classified.
