Emulgel gel contains diclofenac, a nonsteroidal anti-inflammatory drug (NSAID). Diclofenac works by reducing substances in the body that cause pain and inflammation. Emulgel is used to treat joint pain caused by osteoarthritis in the hands, wrists, elbows, knees, ankles, or feet. Emulgel gel may not be effective in treating arthritis pain elsewhere in the body.
