Answer: Medications that thin the blood must be temporarily discontinued prior to each spinal procedure because they can cause internal bleeding and serious complications. Do not stop these medications without permission and specific instructions from our nursing staff, in conjunction with scheduling your procedure. Blood-thinning medications should be temporarily stopped only with written authorization from the outside physician who prescribed them. Injections will not be performed without authorization to stop blood thinning medications. Baby aspirin (81 mg) taken once daily does not have to be stopped before injections.
Blood thinning medications should be stopped before each procedure for the appropriate length of time as follows:
- Coumadin (warfarin): 5 days
- Plavix (clopidogrel): 7 days
- Pletal, Trental, Aggrenox: 5 days
- Ticlid (ticlopidine):14 days
- Aspirin (325 mg): Must be decreased to 81 mg daily for 10 days
- Non Steroidal Anti Inflammatory Drugs (NSAIDS): 48 hours
We perform on-site fingerstick INR testing immediately prior to the procedure, to make sure your blood is clotting adequately. Your injection will be cancelled if this test shows that your blood is still too thin.
All blood-thinning medications should be restarted on the day after each procedure. You may continue taking your other medications that do not thin the blood with a small sip of water prior to procedures.
