Inform your doctor about all medications, supplements, and herbal products you take, as some, especially blood thinners (e.g., aspirin, warfarin), may need to be stopped or adjusted before the procedure. 

Follow specific instructions regarding fasting prior to the procedure, usually no food or drink 6 to 8 hours before; water may be allowed up to 2 hours prior. 

Take a bath or shower on the day of the procedure to reduce infection risk. Avoid applying lotions, perfumes, deodorants, nail polish, or jewelry. 

Arrange for someone to drive you home as anesthesia or sedation will impair driving ability and alertness.
