Skin Testing in Montgomery County, PA

During allergy skin tests, your skin is exposed to suspected allergy-causing substances (allergens) and is then observed for signs of an allergic reaction.  Along with your medical history, allergy tests may be able to confirm whether or not a particular substance you touch, breathe or eat is causing symptoms.

In preparation for these tests, please discontinue use of all antihistamines or antihistamine-containing products for 3 days prior to your appointment.

At the time of scheduled testing, the nurse will give more detailed instructions regarding testing.

Antihistamines include:

• Allegra
• Optivar Eye Drops
• Patanol Eye Drops
• Zaditor Eye Drops
• Fexofenadine
• Clarinex
• Zyrtec (Cetrizine)
• Asteline Nasal Spray
• Claritin (Loratidine)

Some over-the-counter medications contain antihistamines.  Please ask your pharmacist if your prescription or non-prescription medication contains antihistamines before use in the next week prior to your appointment.
