Do these things 7 DAYS BEFORE the procedure:

  • Arrange an escort: You will be given sedative medications during the procedure that make you relaxed and sleepy, therefore you cannot drive a car or travel home by yourself after the procedure. You must have a responsible adult to accompany you home; otherwise your procedure will be canceled and rescheduled. No exceptions. Please inform your escort that the entire visit will last approximately 3 hours.
  • If you have a managed care plan, call to ensure they will cover your procedure.
  • If you are taking Coumadin or any blood thinners – call your prescribing doctor for special instructions about stopping the medication for your procedure.
  • Take your other regular medications as usual, including aspirin or NSAID pain relievers.
