Key takeaways
Lidoderm (lidocaine) and Voltaren gel (diclofenac) are both used to relieve pain, but they work in different ways and are used for different types of pain. Lidoderm is a local anesthetic that numbs the nerves to reduce pain, and it is available in both prescription and over-the-counter forms. It is mainly used for nerve pain, such as pain from shingles. On the other hand, Voltaren gel is a non-steroidal anti-inflammatory drug (NSAID) that reduces pain and swelling by blocking certain chemicals in the body. It is used to treat pain from osteoarthritis in joints like the knees, hands, and wrists, and is available both by prescription and over-the-counter. While Lidoderm can cause mild skin irritation, Voltaren gel can lead to more serious side effects like heart attack, stroke, and stomach bleeding, especially if used in high doses or for a long time. Additionally, Voltaren gel should not be used on the back or hips, whereas Lidoderm patches can be cut to fit smaller areas of pain.
