Do I need to stop medications before skin testing?

Yes and no: antihistamines need to be stopped at least 4 days before skin testing. Antihistamines include Benadryl, Claritin, Zyrtec, Allegra, and most cough and cold preparations. Some anti-depression medications may interfere as well. You may continue to take your asthma inhalers, nasal corticosteroid sprays and other medications for other medical problems.
