Patient education prior to allergy testing:
Prior to the appointment, it is important that patients stop medications that may mask or hide allergies. Typically, guidelines include:
• Stop long-acting antihistamines for 5 days before the testing. Examples include: cetirizine (se TI ra zeen) (Zyrtec), desloratadine (des lor AT a deen) (Clarinex), fexofenadine (fex oh FEN a deen) (Allergra), and loratadine (lor AT a deen) (Claritin, Alavert).
• Stop all OTC cold, sleep, and allergy medication; prescribed allergy medication and specific acid reflux medications 3 days before testing. Examples include: diphenhydramine (dye fen HYE dra meen) (Benadryl), meclizine (MEK li zeen), famotidine (fa MOE ti deen) (Pepcid), and ranitidine (ra NI ti deen) (Zantac).
