Do not stop your prescribed blood thinners before skin surgery

By Bravia Dermatology on 6/21/2018

A question Dr. Molenda at Bravia Dermatology often gets from patients is whether they should stop their blood thinner before surgery.  The answer is almost always no -- do no stop your prescribed blood thinner.  This is especially important for patients with a history of heart attack, stroke, or blood clots.

While being on blood thinners does significantly increase the risk of bleeding, bruising, and hematomas (collection of blood under the skin after surgery), the BENEFITS of these medications greatly OUTWEIGH THE RISKS.  Specifically, bleeding after skin surgery is inconvenient and sometimes a bit messy, but it is not nearly as inconvenient as a heart attack, stroke, or blood clot.

The risk of clots wreaking havoc is a real one… no matter age the patient is.  In fact, even younger people can get blood clots.  One of our very own employees, who was in her 20’s and in good health otherwise at the time, even had a stroke from a blood clot in her neck.  Fortunately, she made a complete recovery but not all patients are so lucky.

Blood thinners (anti-coagulants) work in a variety of ways, and are available by prescription or over-the-counter.

Prescription blood thinners should never be stopped for skin surgery without explicit directions from your physician.  Dr. Molenda suggests that patients on Coumadin (Warfarin) have their INR levels checked prior to surgery and make sure the level is under 3.0.   

Examples of prescription blood thinners include (DO NOT STOP PRIOR TO SKIN SURGERY): 

  • clopidogrel (Plavix) - oral capsure
  • warfarin (Coumadin, Jantoven) – oral tablets
  • enoxaparin (Lovenox)
  • dalteparin (Fragmin)
  • heparin
  • bivalirudin (Angiomax) – powder for injection
  • argatroban (Acova) - injection
  • dabigatran (Pradaxa) – oral capsule
  • apixaban (Eliquis) – oral tablets
  • fondaparinux (Arixtra) - injection
  • rivaroxaban (Xarelto) – oral tablets
  • edoxaban (Savaysa) – oral coated tablets

Examples of Over-The-Counter Blood thinners include aspirin, fish oil, garlic supplements, gingko supplements, and vitamin E.  If these are taken for elective reasons and primary prevention (no personal history of heart attack, stroke, or blood clot), then the over the counter blood thinners can be stopped 1 week prior to skin surgery.
