Initial Preparation

Carefully review the medication lists at the links below. Follow the instructions on when to stop the medications that interfere with allergy testing. If the medication that needs to be stopped was not prescribed by your Texas Ear, Nose & Throat Specialist doctor, contact the prescribing doctor to confirm that you may safely stop taking the medication for the duration required prior to testing.

If you are taking a medication listed under the Beta Blocker list, it is very important that you discuss with your prescribing physician if you may change that medication for testing and long term, should you need to start allergy injections. Patients taking Beta Blocker medications may not receive allergy injections as these medications interfere with the medications we give for extreme reactions and can result in patient injury or even death. If you are unable to change to another medication your treatment plan may need to be changed to medical management or sublingual therapy.

You will need to avoid injections or vaccinations for 72 hours prior to your allergy test.

**Since we are not performing PFTs on everyone, proof of vaccination or negative COVID test is not required for everyone, just those doing the PFTS​​**​

1 Week Prior To Testing

  • A member of our Allergy Team will text you a list of medications to avoid prior to allergy testing. If you have any questions or concerns regarding over-the-counter medications, herbal supplements, eye drops, inhaled medications, and/or nasal sprays please call the office prior to the day of your allergy test.
  • Inform the Allergy Team if you have any respiratory illness or a history of respiratory complaints.

1 Day Prior To Testing

  • Gentlemen: You will need to shave the upper outer side of the right arm from just below the shoulder to above the elbow and both inner forearms from the wrist to the inner elbow area. Do not shave your arms the morning of the test. This must be done at least 12 hours prior to the testing to allow any skin irritation to subside.
  • Ladies and Children: There is no special preparation or shaving that women or children need to do.

The Day Of The Test

  • Do not drink any caffeinated beverages prior to the test.
  • Shower in the morning. Do not apply any perfumes, colognes, or scented products.
