Then call the facility/dept. where the test is being done. You should have been given a number along with an info packet about the test, like Jo*mar stated.

It is not just Rx medications that have to be stopped. Many OTC meds (like Benadryl or other cold/allergy meds) cannot be taken for this test. The facility should give you a complete list and go over what of your Rx meds need to be stopped.
