Dolwin tablet: Each tablet contains Naproxen USP 500 mg.


Dolwin (Naproxen) belongs to a group of medicines called Non-Steroidal Anti-inflammatory drugs (NSAIDs), which are used to reduce inflammation and pain in joints and muscles. Naproxen reduces the prostaglandin synthesis by inhibiting the enzyme, cyclo-oxygenase. Thus it produces anti-inflammatory, analgesic and antipyretic actions.


Naproxen cannot cure arthritis but is used to give relief of some symptoms such as inflammation, swelling, stiffness and joint pain.
