I Accidentally Took Aspirin 4 Days Before Spinal Surgery. Should I Postpone the Surgery?

Doctor Answers 3

Aspirin can cause surgical complications

Aspirin definitely interferes with clotting and increases bleeding during and after surgery in general. In most delicate surgeries, when bleeding is excessive, it may be difficult or impossible to dissect accurately and safely. Excessive bleeding in the postoperative period brings on problems of its own, including the possible need for drainage of accumulated blood, reexploration of bleeding areas, and excessive scar formation. I would definitely postpone a cosmetic procedure if you were my patient.


With regards to spine surgery in particular, there are many types, and differing degrees of urgency - bleeding may be a smaller risk compared to 2 additional weeks of spinal cord compression, for instance.  The cosmetic/plastic surgery specialists on this board are probably ill-qualified to give you specific advice regarding aspirin's safety. Your surgeon would be in much better position to advise you.

Aspirin use prior to surgery

Taking aspirin, even a baby aspirin (81 mg), within 10 to 14 days prior to a surgery can inhibit platelet aggregation and can cause increased bleeding.  Notify your surgeon, before your surgery, that you have taken the aspirin and follow their advice.  Best wishes.

That is a very important question, but one for your surgeon since we have no idea what type of spine surgery you are about to undergo.
