The injection can be painful. Therefore, we provide the option of receiving IV sedation. IV sedation, combined with local anesthetic, to make the injection nearly pain-free. This allows you to remain very still during the procedure, which can also make the injection easier, faster and more successful. If you decide to have IV sedation, you must have a driver to get you home safely afterwards. In addition, you cannot have anything to eat or drink within six hours of your appointment (clear liquids are allowed until two hours before the procedure). If you take medications for diabetes, these medications may need to be adjusted the morning of the procedure. Your primary care physician can help you with this adjustment.
