Key takeaways
Diclofenac (Cambia) and Lidoderm (lidocaine 5% patch) are both medications used to relieve pain, but they belong to different classes and have distinct uses. Diclofenac is an oral non-steroidal anti-inflammatory drug (NSAID) that treats conditions like osteoarthritis, rheumatoid arthritis, and menstrual cramps. Lidoderm, on the other hand, is a topical patch that's approved for nerve pain caused by shingles, known as postherpetic neuralgia. Diclofenac is available in various oral forms, such as tablets and capsules, and is taken multiple times a day, while Lidoderm is applied to the skin once a day for up to 12 hours. Common side effects of diclofenac include headaches, dizziness, and stomach issues, while Lidoderm may cause skin irritation and redness. Diclofenac has serious risks like heart attack and stomach bleeding, especially with long-term use, whereas Lidoderm's main concern is absorbing too much medication if used improperly.
