Can someone tell me how long will emla (lidocaine and prilocaine) cream 5g (5%) numb the surface of the skin for?

Short acting EMLA (lidocaine and prilocaine): Emla (lidocaine and prilocaine) cream applied topically takes 30-60 minutes to work, and lasts for 1 to 2 hours. It is frequently used to aid in intravenous insertion in children.

Thanks for asking!: It depends where on the skin but it usually takes about 20-30 mins for most effective numbness to be achieved.
