Treatment Instructions for the Lidocaine Patch
What If I Take an Overdose of the Lidocaine Patch?A large overdose with this medication could be quite dangerous. Serious effects are most likely to occur when an overdose of this medication is ingested by mouth, rather than applied to the skin.

What Should I Do If I Miss a Dose?If you forget to apply your dose, apply the missed patch as soon as you remember. However, remember that the patches should be worn for only 12 out of every 24 hours.
How Does the Lidocaine Patch Work?The lidocaine patch contains lidocaine, an anesthetic. It works by inhibiting the nerve impulses that pass along pain signals to the brain. At high enough doses, lidocaine can cause complete numbness. However, typically only enough lidocaine passes from the lidocaine patch into the skin to cause pain relief, not complete loss of sensation.
Clinical EffectsThis medication has been thoroughly evaluated in clinical studies. These studies compared the lidocaine patch to a placebo (a patch with no active ingredients). These studies demonstrated that the lidocaine patch was significantly more effective than the placebo for relieving postherpetic neuralgia.
- The lidocaine patch is usually applied to the skin once a day. It can be worn for up to 12 hours only in each 24-hour period. Up to three patches can be applied at once.
- You can cut the patch to a smaller shape if desired, but make sure to do this before removing the sticky liner.
- Apply the patch to clean, dry, unbroken skin.
- After removing the patch, fold it in half with the sticky side together and dispose out of the reach of children and pets.
- For the medication to work properly, it must be used as prescribed.
