I am having a rhinoplasty done in a few weeks and am wondering if I can continue to take my collagen supplement before surgery?

Dear np888,every plastic surgeon has preoperative instructions which he recommends to his patients. Most plastic surgeons would not restrict you from taking collagen supplements but to be sure I would suggest you to discuss this with your plastic surgeon.Daniel Barrett, MD, MHA, MS

In our practice, we ask patients to stop taking all herbal supplements at least two weeks prior to  a rhinoplasty procedure to avoid complications with bleeding and anesthesia. Best to check with your operative surgeon.
