This is a combination medication that contains lidocaine and tetracaine. It belongs to the class of medications called topical anaesthetics.

It is used before laser therapies, such as hair removal, facial resurfacing, tattoo removal, or treatment of varicose veins. It may also be used before insertion of needles into veins.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
Each gram of cream contains 70 mg of lidocaine (7%) and 70 mg of tetracaine (7%). Nonmedicinal ingredients: calcium hydrogen phosphate (anhydrous), methylparaben, paraffin (white, soft), polyvinyl alcohol, propylparaben, purified water, and sorbitan monopalmitate.
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.

If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
It is important to use this medication exactly as prescribed by your doctor. This medication should be applied only once before the procedure and the treatment area needs to fully heal before reapplying the cream.
