If the procedure is not very painful, lidocaine - tetracaine should be applied to the area to be treated for 20 to 30 minutes before. If the procedure is more painful, it should be applied for 60 minutes before. The amount of cream estimated to cover the affected area should be measured out of the tube. Use a flat-surfaced tool such a metal spatula or tongue depressor to spread the cream evenly and thinly over the area to be treated.
After waiting for the cream to dry and form a peel, remove the peel from the skin and dispose of the peel safely. Use gauze to wipe away any cream or peel that does not come off the skin easily. Dispose of the removed peel safely. There is enough medication remaining in the dried film to harm a child or pet. Wash your hands immediately after removing and disposing the peel. This medication will cause numbness to the applied area. It is important to protect this area from scratches and potential causes of burning or freezing until the numbness has stopped.
Although lidocaine - tetracaine is applied to the skin, enough medication can be absorbed to cause side effects. Do not apply this medication to open wounds, irritated skin, or mucous membranes (e.g., inside the mouth or nose). It should not be applied too close to the eyes or inside the ear.
