Preparing for Your Visit

When you have an appointment to have your balance and/or dizziness symptoms evaluated, there are a few procedures you will need to follow prior to the videonystagmography (VNG) or electronystagmography (ENG) testing.

New patients should arrive 15 minutes prior to the scheduled appointment time. Please remember to bring your insurance identification card and referral, if needed.  Patients who have a managed care plan or HMO require this information for billing.

Our office is located at:

Department of Otolaryngology – Head & Neck Surgery
925 Chestnut Street, 6th Floor
Philadelphia, PA 19107

Medications listed below will negatively affect your test results. Stop taking the following medications/products 48 hours before your scheduled appointment:

  • Dizziness medications (Antivert, Meclizine, Valium, Scopolamine)
  • Sedatives (sleeping medications)
  • Muscle relaxants
  • Tranquilizers
  • Antihistamines (including allergy medications)
  • Antidepressants (Prozac, Lexapro, Paxil, Celexa, Elavil)
  • Tobacco products
  • Caffeine (coffee, tea, chocolate)
  • Anxiety medications
  • Alcohol

In addition to the above list, please do not eat or drink anything for 3 to 4 hours before your scheduled appointment. Please be aware that no eye makeup or eyelash extensions are allowed. Tattoo-type eye lines must be covered by foundation. It is also recommended that you wear loose-fitting clothes (no turtlenecks) and avoid wearing wigs. 

The balance test requires approximately 2 hours to complete. We recommend that you bring someone to accompany you. If you have any questions regarding these instructions, please do not hesitate to contact the office at 215-955-6760.
