Two weeks before your procedure, discontinue aspirin, ibuprofen, naproxen, and any supplements that thin the blood, including fish oil, vitamin E, and St. John’s Wort. Nicotine in any form must be stopped at least four weeks prior, as it significantly impairs circulation and healing around the neck and chin. If your procedure is scheduled with oral sedation, you will be instructed to fast for a specific window beforehand, and you will need a driver to take you home.
