What is lidocaine and tetracaine topical?
Lidocaine and tetracaine topical (for use on the skin) is a combination medicine used to numb a small area of your skin. This can help prevent pain during certain medical procedures such as a skin biopsy, minor skin surgery, insertion of an intravenous (IV) needle, or other needle-stick procedures.
Lidocaine and tetracaine topical is also used to numb a skin area during minor cosmetic procedures such as a Botox injection, laser treatment, or tattoo removal.
Lidocaine and tetracaine topical may also be used for purposes not listed in this medication guide.
An overdose of numbing medicine can cause fatal side effects if too much of the medicine is absorbed through your skin. This can happen if you apply more than the recommended dose, or if you leave a skin patch on too long.
Keep both used and unused skin patches out of the reach of children or pets.
Before taking this medicine
You should not use lidocaine and tetracaine topical if you are allergic to:
any type of numbing medicine; or
sunscreen or other skin products that contain para-aminobenzoic acid (PABA).
Fatal overdoses have occurred when numbing medicines were used without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). Be aware that many cosmetic procedures are performed without a medical doctor present.
The lidocaine and tetracaine topical cream should not be used on a child younger than 3 years old. The skin patch is not approved for use by anyone younger than 18 years old.
Tell your doctor if you have ever had:
a blood cell disorder called methemoglobinemia (in you or a family member);
a genetic enzyme deficiency called glucose-6-phosphate dehydrogenase (G6PD) deficiency;
a condition for which you take a heart rhythm medicine; or
allergy to any other medicine used for anesthesia.
Older adults and people who are debilitated may be more sensitive to the effects of this medicine.
Tell your doctor if you are pregnant or breastfeeding.
If you apply lidocaine and tetracaine topical to your chest, avoid areas that may come into contact with the baby's mouth.
The lidocaine and tetracaine transdermal patch may burn your skin if you wear the patch during an MRI (magnetic resonance imaging). Remove the patch before undergoing such a test.

If you use a lidocaine and tetracaine topical skin patch, apply it only to clean, dry, healthy skin on the area to be numbed. Avoid skin that is raw or blistered. Press the patch firmly into place.
You may feel a warming sensation which is normal, but it should not feel unpleasantly hot.
Wash your hands after applying a skin patch.
After your prescribed amount of numbing time, remove the skin patch, then clean and disinfect the skin as recommended by your doctor.

Store unused skin patches at room temperature away from moisture and heat.
Both used and unused skin patches should be kept out of the reach of children or pets. The amount of medicine in the skin patches could be harmful to a child or pet who accidentally sucks on or swallows a patch. Seek emergency medical attention if this happens.
What happens if I miss a dose?
