Voltarol Emulgel is a topical medication primarily used for relieving pain and reducing inflammation. It contains the active ingredient diclofenac diethylammonium, which belongs to a group of medicines known as non-steroidal anti-inflammatory drugs (NSAIDs). Voltarol Emulgel is designed for external application and is effective in treating conditions such as muscle and joint pain, including strains, sprains, and symptoms associated with conditions like osteoarthritis. The emulgel formulation allows for the active ingredient to penetrate deeply into the skin to the site of pain and swelling. It is commonly recommended for its localized action, which tends to offer relief with minimal systemic absorption and side effects compared to oral NSAIDs.
