Voltaren Pain Relief Gel 12 Hourly is a medicated product containing a non-steroidal anti-inflammatory drug in the form of an emulsion gel. The active ingredient, diclofenac, penetrates deep into the skin and provides pain relief for up to 12 hours, without a tablet. It works differently from heat or cooling rubs, that work by heating or cooling the skin. The Emulgel technology used in Voltaren Pain Relief Gel 12 Hourly has an added permeation enhancer, which helps the active ingredient diclofenac to penetrate deeply through the skin and reach the site of the pain, inflammation, and swelling. This formula combines the qualities of a gel and a cream, that has an appealing smell, is easy to rub in and rapidly absorbed, and even provides a cooling and soothing effect when applied to the skin. It is effective for reducing inflammation and relieving muscle pain, and is particularly suitable for women with mild osteoarthritis.
