Dear Jane, This is an important question. Celebrex is an anti iflamatory drug and that class of medication in known for it's side effect as blood thinners. Not every person reacts in the same way to blood thining medications, however, since the consequences of bleeding can be quite detrimental to the final outcome, it is wise to stop them before surgery. In my practice, every patient gets a diet and medication sheet to avoid 2 weeks prior to surgery. Always, consult with experienced board certified plastic surgeons who operate in accredited surgery center for your safety. Most importantly, check their before and after pictures to make sure that they are numerous, consistent and attractive. Check also the 'realself' reviews for positive patients experience which provides important information on the surgeons. Best of luck, Dr Widder
