Lidocaine / Prilocaine Side Effects
What should I watch for?
Be careful to avoid injury to the treated area while it is numb and you are not aware of pain. Avoid scratching, rubbing, or exposing the treated area to hot or cold temperatures until complete sensation has returned. The numb feeling will wear off a few hours after applying the cream.
