GLP-1 receptor agonists delay gastric emptying, increasing the risk of aspiration during anesthesia, necessitating specific preoperative discontinuation guidelines.

If you take Ozempic and have surgery, tell your surgeon. You likely need to stop the drug 1-7 days before surgery to prevent vomiting during anesthesia. Follow your doctor's specific instructions.
