How Should I Prepare for Allergy Testing?

  • Wear comfortable clothing. Please wear a loose, short-sleeved, or sleeveless shirt or blouse to your testing appointment.
  • Stop using antihistamines before skin testing. Drugs such as Zyrtec, Allegra, Claritin and Benadryl need to be stopped 3-5 days before your skin test. Many over the counter allergy and cold medications, such as Dimetapp, Triaminic, Tylenol PM and others contain antihistamines and also should be stopped for the same amount of time. If you are not sure if your medication contains antihistamines, ask us or your pharmacist for advice.
  • Clarinex should be stopped for at least one week before your skin test.
  • Some medications for nausea, heartburn/reflux, depression, anxiety, and insomnia may affect your skin test. Ask us if there are questions–some of these medications may not be safely stopped without a doctor’s assistance/supervision.
  • If you take Beta blockers (heart/blood pressure medication), please contact our office before scheduling a skin test.


  • Steroid nasal sprays
  • Sudafed (plain) for a decongestant
  • Singulair
  • Inhalers: If you have a rescue inhaler (albuterol), please bring this to the testing appointment.
  • You may eat and drink the day of testing.
  • Do not stop your asthma medications (inhalers, Singulair). We will not be able to perform the skin test if your asthma is not well controlled.

If you have any concerns or questions before skin testing, please discuss them with one of our physicians or staff or call the Allergy Center at 570-483-4374.

As always, our ultimate concern is your safety and comfort.
