Special Instructions

1. For those taking Blood Thinners:

  • If you are taking any of these medications: Coumadin®, Janotven®, Plavix®, Brilanta®, Pradaxa®, it is necessary to stop taking them for 5 days prior to myelogram. Consult with your physician first.
  • If you are on Enoxaparin (Lovenox®) or Rivaroxaban (Xarelto®), stop taking this medicine during the 24 hour period before procedure.(Consult with the physician who prescribed this for you.)
  • If you have been taking blood thinners, you will need to have an INR lab test done the day before the myelogram. This test can be done at St. Mary's Regional Medical Center's main location or at lab in the Auburn Medical Building (corner of Gracelawn and Turner Road in Auburn). (The results of the INR must be within normal limits to prevent bleeding at the injection site.)
