Prepare For Your Allergy Visit
Prepare for your allergy appointment to help ensure accurate testing and an effective treatment plan. Understanding what to bring, which medications to pause, and what to continue can make your visit smoother and more productive.
Overview Instructions
Your appointment typically includes a complete medical history and allergy testing, which may take 60–90 minutes.
Important Instructions:
– Stop antihistamine medications 72 hours prior to testing (see list below).
– Continue all other medications as prescribed.
– Do not stop any medications if you have active hives, rashes, swelling, or recent ER visits.
Allergy evaluation is still possible even if you continue other medications, but pausing antihistamines improves test accuracy.
What to Bring
– Records of previous allergy tests or recent ER visits.
– A list of current medications and dosages—or bring all medication bottles.
– Any inhalers or spacers you currently use.
