You should avoid blood thinners (aspirin, ecotrin, Bufferin, Excedrin, Anacin, ibuprofen, Motrin, Nuprin, Aleve, and any prescription NSAID unless specifically OK'd by your doctor) as well as Vitamins E, D, and A (they inhibit absorption of Vitamin K, which is needed for proper healing and sealing of injured blood vessels), herbal medications, and Omega 3's (see Vitamin K absorption above).Tylenol, by the way, is OK, as it does not interfere with proper vessel sealing like most of the others do.Avoid appetite suppressants (even over the counter ones) as they can interfere with anesthesia drugs. Also stimulants like Ritalin and Adderal, and certain other medications (ask if you are not sure) should be stopped at least two weeks before surgery.Avoid tobacco or any kind of nicotine (including second-hand smoke) for a minimum of two weeks before and after surgery to avoid dead skin and major problems.Obviously, abstain from alcohol or marijuana (or other illegal drugs) before surgery. Be honest with your anesthesia provider or surgeon if you have used these drugs, for it makes a difference with your anesthesia protocols.If you take prescription medications, review this list with your surgeon and/or anesthesia provider to make sure they are compatible with your anticipated surgery. Be safe--the time to discuss these things is indeed now, not the day before surgery! Best wishes! Dr. Tholen
