Iodex UltraGel is a pain relief gel which provides effective and long-lasting relief from multiple types of body pain such as neck and shoulder pain, back pain and joint pain. It contains the formulation of one of the World’s Top Topical Pain Relievers- Voltaren (1.16% w/w Diclofenac Diethylamine, an NSAID with emulgel formula – for topical use). This formula helps permeate through the skin 7 Times more (vs 5% diclofenac sodium gel formulation). It, therefore, provides much better penetration, reduces internal swelling/inflammation (which is generally the cause of the pain) & treats pain at its root.
