This medication contains 2 amide-type local anesthetics, lidocaine and prilocaine. It is used on normal, unbroken skin or on the outer genital area to prevent pain before certain procedures such as inserting a needle, skin grafts, or skin laser surgery. It works by temporarily numbing the skin and surrounding area. Do not use this product in the ears.
If this product alone cannot completely numb the area being treated, it may be used to numb the area before a lidocaine injection is given to provide enough pain relief for certain procedures (e.g., removal of genital warts).
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.
Use this medication only on normal skin and the genital area. Do not apply to broken/irritated skin or open wounds unless directed by your doctor. Wash your hands before using this product.
Apply this product to the area at the proper time as directed. The length of time for the medication to stay on the skin depends on the type of procedure you are having. It is usually applied at least 1 hour before needle sticks and 2 hours before minor skin procedures. It may be applied by a health care professional before certain genital procedures. In this case, it is recommended that you remain lying down so the medication will stay in place.
To apply, squeeze out the prescribed amount of cream directly onto the skin. You can also squeeze it onto a measuring guide to make sure you get the right dose and then apply it to the area. Do not rub in. Cover with an airtight dressing/bandage as directed by your doctor. Allow the cream to remain in place, usually in a thick layer, as directed by your doctor. Remove the dressing and cream and clean the area thoroughly, usually shortly before the procedure or as directed by your doctor.
Dosage and length of application time are based on your age and medical condition and the procedure you are having. In children, dosage may also be based on weight. Do not use larger amounts than prescribed. Do not use on large areas of skin, apply heat, or leave it in place longer than directed or serious side effects may occur.
If you are applying this product on a child, make sure the medication stays in place and that your child does not put the medication or dressing/bandage in his/her mouth. You may want to use a second covering to prevent the child from touching the cream.
Wash hands immediately after use unless you are treating an area on the hands. 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 area may be numb for several hours after the procedure. Protect the area from injury. Be careful not to bump, rub, or scratch the area or expose it to heat/cold until feeling returns.
Redness, swelling, tingling/burning, or lightening of the skin may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
