Lidocaine-Prilocaine

This medication is a patch that contains 2 amide-type anesthetics for numbing a small area, lidocaine and prilocaine. It is used on normal, unbroken skin to prevent pain before certain procedures such as inserting a needle for injections or drawing blood. It is also used before certain vaccinations (measles/mumps/rubella-MMR, diphtheria/pertussis/tetanus/poliovirus-DPTP, H. influenzae b, hepatitis B). It works by temporarily numbing the skin and surrounding area. This medication should not be used in premature infants (infants born before 37 weeks of pregnancy).

If you miss a dose, contact your doctor to establish a new dosing schedule.

This medicine comes with a Patient Information Leaflet. Read it carefully for instructions on how to use this product. Ask your doctor, nurse, or pharmacist any questions that you may have about this medicine. Clean and dry the skin before applying the patch. Peel away the protective liner and place the disc on the procedure site, usually 1 hour before the procedure or as directed by your doctor. Do not touch the white round part that contains the medication. Firmly press down on the edges of the patch to make sure it is well attached. Gently press on the center of the patch. Using a ballpoint pen, mark on the patch the time it was placed. Remove the patch and clean the area thoroughly, usually shortly before the procedure or as directed by your doctor. The length of time for the medication to stay on the skin depends on your age and the type of procedure you are having. Do not leave it in place for longer than directed since the chance for side effects may be increased. Carefully fold the patch in half with the sticky sides together and discard out of reach of children and pets. Do not re-use the patch. Wash hands immediately after use unless you are treating an area on the hands. This patch may be harmful if placed in the mouth or swallowed. If you are applying this product on a child, make sure the patch stays in place and that your child does not put the patch in his/her mouth. You may want to use a second covering to prevent the child from touching the patch. Use this medication only on normal, intact skin. Do not use on open wounds/cuts/scrapes/burns/rashes (including diaper rash) or mucous membranes. Do not use this product in the ears or near the eyes. Avoid getting the product in your eyes, nose, ears, or mouth. If this medication gets in the eyes, rinse the affected eye immediately and completely with water or saline. Numbness in the eye can lead to injury because you cannot feel particles in the eye or other dangers. Therefore, protect the eye until feeling returns. The numbing effect should start within 1 hour. The area may be numb for several hours after removing the patch. Protect the area from injury. Be careful not to bump, rub, or scratch the area or expose it to heat/cold until feeling returns.
