What Do I Need To Do
Before My Environmental Allergy Test?

Preparing For Your Allergy Test

We want to make sure your appointment is as successful as possible, which is why we ask that you avoid taking certain medications that may interfere with the effectiveness of your allergy test before coming in.

At Least Five (5) Days Before Your Test

Wear short sleeves to your testing appointment.

Please be sure to stop taking the following medications at least 5 days prior to your appointment:

  • All anti-histamines (Claritin, Allegra, Benadryl, Zyrtec, etc)
  • All vitamins and supplements
  • Allergy eye drops
  • Any sublingual immunotherapy (allergy drops)
  • Advil PM
  • Tylenol PM
  • NyQuil and any medication that may contain benadryl or antihistamines (please read your labels)

If you find it difficult to stop taking allergy medications for 5 days due to ongoing symptoms, you can take Benadryl, Patanase (i.e. nose spray), and/or Pataday (i.e. eye drops) up to 3 days before your appointment.

Additionally if you are taking any prescription medications, it is critical that you contact us at 512-628-5989 to speak with a nurse. They can assess and identify any issues with your medication that could interfere with testing.

These medications include:

  • Heart Medications
  • Blood Pressure Medications
  • Tricyclic Antidepressants (TCA)
  • Psychiatric Medications
  • Sleep Aides
  • Over-The-Counter (OTC) medications

Beta Blockers

Please stop taking all beta blockers 24 hours before your allergy test.

Have You Experienced A Severe Reaction?

Please let us know if you have ever been to the emergency room or used an Epipen for a severe allergic reaction of any kind.


Are you pregnant? Could you be pregnant? If you answered yes please contact our office at 512-628-5989.
