Medications that may inhibit ability to clot blood
When undergoing some procedures or operations, it is important that your blood be able to clot. Many over-the-counter and prescription drugs, in one or several ways, may prevent your blood from properly clotting in a timely fashion. The most common of these medications are the analgesics (medications that minimize pain) and the anti-inflammatory compounds (medications that reduce inflammation or swelling), although there are others as well.
Tylenol® is a trade name for "acetaminophen." Compounds that contain acetaminophen do NOT (by themselves) affect your ability to clot your blood. Therefore, they are safe to take in the days preceding surgery, provided they do not also contain a mixture of any of the compounds listed below. Some medications are a blend of different analgesic or anti-inflammatory compounds. Most over-the-counter "cold remedies" contain acetaminophen, but please read the ingredients label carefully.
The long list below contains some of the more common medications that fall into this category. If you have recently (anytime within the past two weeks) taken any of these medications, or anything that you believe to be similar, please let us know. Of course, there may be other medications not mentioned here; and so if you are in doubt, please callus and inquire.
