Voltaren Emulgel is an anti-inflammatory topical gel for the temporary relief of muscle and back pain such as acute tissue injuries including sprains, strains, tendinitis and sports injury. The active ingredient, diclofenac, penetrates into the skin to the source of inflammation, to relieve pain 2x faster (50% pain relief at 2 days vs 5 days for placebo). Voltaren Emulgel has a triple benefit: it provides pain relief, reduces inflammation and helps get you moving sooner.* The emulsion gel combines the properties of a gel and a cream, so it both cools and has a moisturising effect.
