MEDICATIONS TO AVOID PRIOR TO ALLERGY SKIN TESTING
Allergy testing requires the ‘histamine response’ in order to be accurate and reliable. There are many types of
antihistamines. Antihistamines are found in many different medicines, either as a single drug or mixed with a
combination of chemicals. Please review all medicines you take (including Over-The-Counter) in order to make
your allergy testing appointment most efficient and accurate. Generic names are in all lower case, trade names
Capitalized.
