You should not receive this medicine if you have had an allergic reaction to lidocaine, tetracaine, or any other numbing medicines (such as lidocaine, procaine, Carbocaine®, Marcaine®, Novacaine®, or Sensorcaine®).
A nurse or other trained health professional will give you this medicine.
The patch is applied to your skin about 20 to 30 minutes before your procedure. Do not cover the vent holes in the top of the skin patch while you are wearing it. Tell your doctor if you still have feeling in the skin after 30 minutes have passed.
This medicine is for use on the skin only. Do not get it in your eyes, nose, or mouth. Do not use it on skin areas that have cuts or scrapes. If it does get on these areas, rinse it off right away.
Do not apply this medicine to a large area of skin, or to broken or irritated skin.
Do not cover the treated area with a bandage unless your doctor has told you to.
Do not cut the patch or tear it apart in any way. This could cause medicine to leak out of the patch and burn your skin.
Make sure your doctor knows if you are pregnant or breastfeeding, or if you have liver disease.
Tell your doctor if you have had breathing problems caused by general anesthesia during a surgery.
It is very important to check with your doctor first about using this medicine before having medical tests to examine your breasts or other medical procedures. Using this medicine before having a medical test for your breasts or before having certain other medical procedures may increase your risk of serious side effects.
You may not have feeling in your treated skin areas for several hours after using the skin patch. Be careful not to accidentally injure the skin by scratching or rubbing it while it is still numb. Avoid exposing the skin to very hot or cold temperatures until your feeling returns.
If you need to have an MRI (magnetic resonance imaging) scan, the skin patch must be removed before your scan.
