Voltaren Emulgel is a medicated product containing a non-steroidal anti-inflammatory drug, or NSAID, in the form of an emulsion gel. The active ingredient (diclofenac) penetrates the skin to provide relief for pain and inflammation.
It works differently from heat or cooling rubs, which contain ingredients that stimulate nerves in the skin to provide a sensation of heating or cooling. Voltaren Emulgel instead allows an anti-inflammatory (diclofenac) to penetrate the skin deep down in order to relieve pain and reduce inflammation where you need it.
