Can you drink alcohol after a local anesthetic?

Sedation temporarily affects your coordination and reasoning skills, so you must not drive, drink alcohol, operate machinery or sign legal documents for 24 hours afterwards. If you're in any doubt about driving, please contact your motor insurer so that you're aware of their recommendations and always follow your doctor/surgeon's advice.
