Why is this medication prescribed?
To treat the pain of post-herpetic neuralgia, prescription lidocaine transdermal (Dermalid, Lidoderm, Ztildo) is utilised (PHN; burning, stabbing pains, or aches that may last for months or years after a shingles infection). For modest pain in the shoulders, arms, neck, and legs in adults and children 12 years of age and older, nonprescription (over-the-counter) lidocaine (Absorbine Jr, Aspercreme, Lidocare, Salonpas, among others) is also offered. Lidocaine is a member of the local anaesthetics drug class. It functions by preventing pain signals from being sent by nerves.
How should this medicine be used?
Prescription-only transdermal lidocaine is available as a 1.8% topical system (Ztlido) and as a 5% patch (Dermalid, Lidoderm). Only once daily, as needed, is prescription lidocaine transdermal used to treat pain. Never use more than three lidocaine 5% patches or lidocaine 1.8% topical systems at once, and do not wear them for longer than 12 hours each day (12 hours on and 12 hours off). Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Follow the lidocaine transdermal directions exactly. Apply it only as directed by your doctor, neither more nor less frequently.
Non-prescription transdermal lidocaine is available as a 4% patch (Absorbine Jr, Aspercreme, Lidocare, Salonpas, among others). Up to three applications per day are made, each lasting no longer than eight hours. Apply non-prescription lidocaine patches precisely as instructed. Use just as indicated by the instructions on the package. Do not use more or less of it, or use it more frequently or for a longer period of time.
How many lidocaine patches or topical systems you can use at once, as well as how long you can wear the patches, will be determined by your doctor. Serious negative effects may result from applying too many patches or topical systems or from leaving them on for too long.
To clean, dry, intact skin, use the lidocaine patch or topical system as prescribed. Select a location where clothing that is too tight won’t rub the patch. Applying the patch or topical system to skin that is open, cut, inflamed, red, or suffering from a rash, burn, or another skin condition is not advised. When applying lidocaine, if irritation or a burning feeling develops, remove the patch or system and wait until the discomfort subsides before applying it again. Before removing the release liner, prescription patches and topical systems can be cut into smaller sizes with scissors. Prior to installing a new patch, make sure you uninstall the existing one.
Keep your eyes away from the transdermal lidocaine solution. If lidocaine transdermal does get in contact with your eye, flush it out with water or saline as away, then cover it until your sensibility returns.
Avoid using hot pads or electric blankets on the treated region while you are wearing a lidocaine transdermal patch or system. After moderate heat exposure, such as 15 minutes on a medium-hot heating pad, you can use the lidocaine 1.8% topical system. Avoid tightly bandaging the injured region.
While using the prescription lidocaine 5% transdermal patch, avoid bathing, swimming, or taking a shower. You can take a 10-minute shower while wearing the prescription lidocaine 1.8% topical system, or you can submerge it in water for up to 15 minutes. Do not rub the skin or the lidocaine 1.8% topical system if it becomes moist. Instead, gently pat the skin.
Press hard on the margins of the lidocaine 1.8% topical system or elevated portions to reattach it if it totally falls off or lifts at the edges. Apply a fresh lidocaine topical system for a maximum of 12 hours of use if the lidocaine 1.8% topical system fully comes off more than once and does not adhere to the skin.
After using lidocaine patches or a topical method, wash your hands.
If your discomfort persists for more than seven days or if it gets better before getting worse, stop using the non-prescription lidocaine 4% patch and notify your doctor.

Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org
