What to Expect and How to Prepare for Allergy Testing in our Office


Many medications can interfere with skin allergy testing results. Please avoid the medications below at least 5 days prior to anticipated testing. You do not have to discontinue medications such as nasal steroid sprays or inhalers.


Prescription antihistamines, such as levocetirizine (Xyzal) and desloratadine (Clarinex).
Over-the-counter antihistamines, such as loratadine (Claritin, Alavert), diphenhydramine (Benadryl, others), chlorpheniramine (Chlor-Trimeton), cetirizine (Zyrtec, others) and fexofenadine (Allegra).
Tricyclic antidepressants, such as nortriptyline (Pamelor) and desipramine (Norpramin).
Certain heartburn medications, such as cimetidine (Tagamet) and ranitidine (Zantac).
The asthma medication omalizumab (Xolair). This medication can disrupt test results for six months or longer even after you quit using it (most medications affect results for days to weeks).


Test are performed by placing small pricks on the skin of the arms that contain the common inhalant allergens. Wear comfortable, loose fitting clothes such as short sleeves.
