Answer:

There are a number of supplements and herbs that can interfere with anesthesia or increase the risk of bleeding, cardiovascular events, or other complications during and after surgery. Always tell your doctor and surgeon about the supplements you take; unfortunately, an estimated 70% of patients do not. For information about specific supplements to avoid before surgery, see the full answer >>

I wonder if SAMe needs to be stopped before surgery. Apparently one of its benefits is that it may be like an anti-inflammatory. My pre-op instructions advise to quit taking all anti-inflammatory supplements and medications. Would SAMe be considered an anti-inflammatory supplement to avoid before surgery?

Due to SAMe's potential effects on neurotransmitters such as serotonin (which can affect the central nervous system and the vascular system) theoretical concerns have been raised about taking SAMe before surgery, but there do not seem to be any reported cases of injury.

Clinicians DON'T ASK about supplements!! I had to make an appt with my clinician to get them listed on my current medications because IF I was ever admitted to the hospital or in the ER, those clinicians should be able to to look at my medical record and see that info.

My teeth would bleed terribly when I went to the dentist for cleaning. Since avoiding the 81mg aspirin and fish oil the day of the visit, I have had NO problem. I take ginger, turmeric, glucosamine and chondroitin daily and do not stop them. I have had 2 outpatient surgeries in 2018 and did stop all the supplements that you mention for them.

I've performed anesthesia for thousands of surgical patients. I cannot quote you any hard facts from the medical literature on nutriceuticals and risks of peri-operative complications (mostly because there aren't a lot of hard facts on the subject). But, like with the investigations of the effects of fish oil supplements on surgical bleeding risk, I feel that very few of the products mentioned, when used responsibly, have any significant medical/surgical risks that would require stopping their use pre-operatively. There are exceptions of course, e.g., ephedra and other stimulants (which shouldn't be taken in the first place!). But, given that almost all supplements can be done without for a while, and given the pre-operative policies of most surgeons and anesthesiologists, it's probably best simply to stop your products pre-operatively as requested.

Thanks so much for this - I have a pre-op appointment today and I take a boatload of supplements, many of which are on this list!

I have never been asked in any pre-op appointment about supplements. I knew about the ones that are taken for inflammation but I've never stopped my omegas. Interesting.

Eight days before routine hernia surgery I was surprised when the nurse reviewing my meds and supplements told me to stop taking CoQ10 immediately.
