@toddybob Welcome to Mayo Connect. I'm no doctor, but have lived for a long time with pain due to arthritis, among other issues. After long, long, long term use of oral NSAID (non-steroidal anti-inflammatory drug) medications I am considered to be at high risk for damage from constant use. I have been advised not to take them orally for more than a few days at a time. I do not, however, currently have either kidney or liver failure.

Voltaren gel is my salvation on really bad days. It is far more effective for me than the rubs that are primarily made up of ingredients give a warming or cooling effect, probably because it has anti-inflammatory properties. I find using it after a warm shower seems to be more effective.

I discussed the risks with both my primary doc & my pain management doc. I also did a lot of reading. Here is what I get from all of it - Yes, Voltaren is an NSAID, so it carries some of the same risks as if it was taken internally. However, used topically, a LOT LESS or the drug makes its way into the bloodstream and organs than when taken orally, thus it is considered safer. But, it should only be used according to directions for the number of times per day and the amount.

So if your wife does not already have kidney or liver function issues, and it is okay with her docs, it is probably safe for her to try.
Has someone recommended Voltaren to her? There are also generic versions on the market that are a little less expensive.
