Medications That Interfere With Allergy Testing

Many common medications, especially antihistamines, interfere with allergy skin testing. Antihistamines are in many over-the-counter medications for allergies, colds and sinus problems.  It is important to stop taking these medications at least 5 full days prior to your visit so that skin testing can be performed at your appointment.

If you are currently experiencing significant skin symptoms such as hives (urticaria) or swelling (angioedema), or if you were put on antihistamines for a severe allergic reaction (anaphylaxis), DO NOT STOP your antihistamines without contacting our office at 518-434-1446.
