Voltaren Emulgel is used to treat inflammation of muscles, joints, tendons, and ligaments, due to trauma (eg. sports injuries, sprains and strains); soft tissue rheumatism and localised rheumatic conditions (eg. bursitis; aches and pains).Effect:Voltaren Emulgel contains the non-steroidal anti-inflammatory drug (NSAID), diclofenac. Diclofenac works to relieve pain and reduce inflammation (swelling). The Emulgel technology helps the gel to penetrate deeply into the skin to enhance delivery of diclofenac to the site of pain. Voltaren Emulgel has a cooling, moisturising effect with no strong odours.
