Voltaren Emulgel 2% is a topical gel containing diclofenac diethylamine that provides up to 12 hours of pain relief. It is specifically formulated to treat muscle and joint injuries, soft-tissue rheumatism (tendonitis), and arthritis pain by reducing inflammation and swelling. This 50g gel formulation is designed for external use only and should be gently massaged into the affected area. The active ingredient, diclofenac diethylamine, belongs to the class of non-steroidal anti-inflammatory drugs (NSAIDs). The emulgel formulation allows for better absorption through the skin to target pain and inflammation directly at the source. For best results, apply 3-4 times daily unless otherwise directed by a healthcare professional.
