Lidocaine and tetracaine topical

Lidocaine and tetracaine topical (for use on the skin) is a combination medicine that numbs a small area of your skin. This helps prevent pain during certain medical procedures like 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 other reasons not mentioned in this medication guide.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Never use this medicine in larger amounts, or for longer than prescribed.

This medicine is usually applied 20 to 30 minutes before your procedure (or 60 minutes before tattoo removal).

Lidocaine and tetracaine topical comes in a cream or a skin patch.

If you use this medicine at home, read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Do not take by mouth. Topical medicine is for use only on the skin. If this medicine gets in your mouth, nose, rectum, or vagina, rinse with water.

For a cosmetic procedure, a healthcare professional or other care provider will apply this medicine to your skin.

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.

After removing a skin patch: fold it in half with the sticky side in, and throw it away in a place out of the reach of children or pets.

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.

An overdose of numbing medicine can lead to serious side effects that could be fatal if too much medicine is absorbed through your skin. This can occur if you use more than the recommended dose, or if you leave a skin patch on for longer than advised.

Keep both used and unused skin patches away from children and pets.

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 happened when numbing medicines were used without the guidance of a medical doctor (such as during a cosmetic procedure like laser hair removal). Be aware that many cosmetic procedures are done 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 anyone younger than 18 years old.

Tell your doctor if you have ever had:

• liver disease;
• 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
• an allergy to any other medicine used for anesthesia.

Older adults and people who are weak 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 touch 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 having this test.

Get emergency medical help if you have signs of an allergic reaction: hives; wheezing, difficulty breathing; swelling of your face, lips, tongue, or throat.

Tell your caregivers or call your doctor right away if you have:

• severe burning, stinging, or other irritation where the medicine was applied;
• sudden dizziness or drowsiness after the medicine is applied;
• pale, gray, or blue colored skin;
• headache, fast heartbeats, shortness of breath;
• tiredness, or feeling like you might pass out;
• blurred vision, ringing in your ears; or
• unusual sensations of hot or cold.

Common side effects include:

• skin redness;
• skin swelling; or
• changes in skin color where the medicine was applied.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Since lidocaine and tetracaine topical is used as a single dose, there is no daily dosing schedule.

Seek emergency medical help or call the Poison Help line at 1-800-222-1222. Taking too much numbing medicine can lead to life-threatening side effects if too much of the medicine gets into your bloodstream through your skin.

Your body might absorb too much lidocaine and tetracaine topical if:

• you use more than the recommended dose;
• you put the medicine on skin that is cut or irritated; or
• you keep a skin patch on your skin for too long.

Signs of an overdose may include numbness or tingling in your face, ringing in your ears, feeling sleepy, nausea, and slurred speech. Serious problems from a lidocaine or tetracaine overdose could include seizures (convulsions), slow breathing, coma, heart failure, or respiratory failure (when breathing stops).

Do not let this medicine touch your eyes. If it does, rinse your eyes with water.

Do not use a skin patch if it is cut or damaged.

Avoid touching the sticky side of a skin patch while you are applying it.

Do not get a "live" vaccine while using lidocaine and tetracaine. The vaccine may not work as well and may not fully protect you from illness. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, and varicella (chickenpox).

Medicine applied to the skin is not likely to interact with other drugs you take. However, some drugs can lead to conditions that may make using lidocaine and tetracaine topical harmful for you. Inform all your healthcare providers about all the medicines you use, including prescription and over-the-counter medicines, vitamins, and herbal products.
