Voveran Emulgel (Diclofenac Sodium) is a topically applied NSAID (non-steroidal anti-inflammatory drug) that works by relieving pain. It is indicated for the treatment of painful joints (especially in the ankles, knees, wrists, elbows and hands). 
This gel works by inhibiting the enzyme known as COX (cyclooxygenase), thereby decreasing the amount of inflammatory prostaglandins that are formed. As a result of this, pain and swelling may be relieved. 
Voveran Emulgel (Diclofenac Sodium) is provided as a non-greasy formula which should be gently massaged into the skin. 
Directions of use:
It should be applied 4 times per day, in the morning, after eating lunch, and again after dinner followed by a final application just before going to bed. 
However, it is important to note that the required frequency of application could vary depending on individual circumstances. 
Caution:
It is important that excess gel is not applied, and if your hands are being treated, do not wash them for at least 1 hour after application.
