Yes. You should tell your surgical and anesthesia team about all supplements and herbs before surgery. That includes vitamins, minerals, over-the-counter drugs, herbal remedies, and dietary supplements. Your team needs the full list because some of these can affect bleeding, interact with other medicines, or change how anesthesia works. Some medicines and supplements may need to be stopped before surgery, and some should not be stopped. In some cases, your anesthesia team may tell you to stop supplements 1 to 2 weeks before surgery, and some examples of medicines or supplements that may need to be stopped up to 7 days before surgery include NSAIDs like aspirin or ibuprofen, blood thinners, fish oil, vitamin E, garlic, ginseng, ginkgo biloba, and St. John’s wort. Bring your medication and supplement bottles or an up-to-date list with you. Verify the exact plan with your surgical or anesthesia team in case they want something different for you.
