How Fenak 50 mg Tablet Works

Fenak 50 mg Tablet contains diclofenac and belongs to a class of medicines called nonsteroidal anti-inflammatory drugs (NSAIDs). When your body experiences injury or joint damage, it produces natural chemicals called prostaglandins, which trigger pain, fever, and swelling. This medicine works by blocking the specific enzymes (known as COX enzymes) responsible for making these prostaglandins. By lowering the production of these chemicals in your body, Fenak 50 mg Tablet effectively reduces both the painful sensations and the physical swelling in your joints and muscles.
