Who Should Not Have Allergy Skin Testing?
If you are taking beta-blockers (like Toprol, Metoprolol, Inderal, Atenolol) for blood pressure control or a heart condition or have asthma that is difficult to control (frequent wheezing, shortness of breath or frequent inhaler usage) you should not undergo skin testing because of the increased risk for a severe allergic reaction called anaphylaxis. Blood tests should be done instead.
