How Lidocaine/menthol patch works
Lidocaine/menthol patch is a combination of two medications.
- Lidocaine is a local pain reliever. It eases skin discomfort by numbing the nerves and making them less sensitive to pain or irritation. Lidocaine works locally, which means it lowers pain in the area of skin closely around or directly in contact with the medication.
- Menthol is a chemical found in peppermint or other mint plants. It works by causing a cooling sensation that makes the nerves on your skin less sensitive to pain.

Pharmacist tips for Lidocaine/menthol patch
- Don't use more than one patch of lidocaine/menthol patch at a time. Also, avoid using other topical pain medications while you use lidocaine/menthol patch. This is because lidocaine can be found in many over-the-counter pain medications that you apply on your skin. Using too much lidocaine can cause you to absorb more of the medication, which can lead to skin irritations or more serious side effects, such as seizure, heart rhythm problems, and coma.
