Head-to-head comparisons of medication uses, side effects, warnings, and more.
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 patch 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. While Lidoderm can be used for temporary relief of minor pain, Voltaren gel is specifically for arthritis pain and is not recommended for use on the back or hips. Both medications have generic forms. Voltaren gel is available over-the-counter, whereas certain strengths of Lidoderm require a prescription. Both medications can cause skin irritation, but Voltaren gel also carries risks of serious side effects like heart attack and stroke due to its NSAID properties.
Lidocaine 5% patch (Lidoderm) is a prescription medication used to relieve nerve pain caused by a shingles infection, also called postherpetic neuralgia (PHN). It's a local anesthetic that works by numbing your nerves to help reduce pain. You apply the patch directly to the painful area of your skin once a day, and it can be worn for up to 12 hours in a 24-hour period. Common side effects include temporary skin irritation, redness, and a mild burning sensation where the patch is applied.
Diclofenac sodium topical gel (Voltaren gel) and diclofenac sodium topical solution (Pennsaid) can help ease arthritis pain from osteoarthritis. They're applied to the skin of the affected joints, typically 2-4 times daily, depending on which topical product you use. Some common side effects of topical diclofenac include dry skin, redness, and itching. Because diclofenac is a non-steroidal anti-inflammatory drug (NSAID), these topical products can also raise the risk for NSAID-related side effects, such as blood clots and high blood pressure. While the diclofenac sodium topical solutions are only available by prescription, you can get diclofenac sodium 1% topical gel over-the-counter or by prescription.
