What is the difference between Flector patch and Voltaren gel? My wife needs diclofenac because she?

Without getting into a very in depth discussion of Pharmaceuticals, Voltaren gel and Flector patch are virtually the same drug. The active ingredient, which is called Diclofenac, is what is going to treat your wife's condition. Each of the products obviously contain Diclofenac, but are placed in a different inactive ingredient, called a base used to deliver the drug so that it dissolves properly etc... The Flector is Diclofenac, placed in a fancy sounding base called Epolamine and Voltaren Gel a.k.a Diclofenac is placed in a base called Sodium, both of which are inactive ingredients which will not enhance or decrease the effectiveness of the Diclofenac which is the ACTIVE ingredient in both of these products. Any further questions, please ask. I hope this helps until you can speak with your health care provider.

Flector Patch and Voltaren Gel contain the same medicine (diclofenac).

Diclofenac is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by reducing hormones that cause inflammation and pain in the body. Diclofenac is used to treat pain or inflammation caused by arthritis or ankylosing spondylitis.

The Flector Patch is designed to deliver diclofenac at a constant rate. Using the Voltaren Gel should work just as well... you may need to apply it more often.
