Numbs the skin to make needle sticks less painful.
HOW IT'S SUPPLIED:
Cream containing lidocaine 2.5% and prilocaine 2.5%
5- and 30-gram tube
Discs containing 1 gram of medicine
HOW IT WORKS:
Absorbed into the skin and numbs the nerve endings and pain receptors there so that pain is not felt.
THINGS TO DISCUSS WITH YOUR DOCTOR:
* Should be applied two hours before the procedure to the area that the doctor plans to treat.
* Should not be put over scratched or broken skin or near eyes
* The cream should be applied very thick (about 1\4 inch thick) to the site of the procedure.
* Do not rub the cream into the skin. Instead, cover it with saran wrap being careful not to press on the cream so it stays thick.
* Skin numbness lasts for about an hour after the medicine is removed.
* The skin under the medicine may become pale or light red in color. This goes away a few hours after the medicine is removed.
* May cause an allergic reaction
* Using too much cream at one time may cause changes in the heartbeat.
* Do not use in people who have methemoglobinemia or liver disease.
