Naproxen is a commonly prescribed NSAID known for relieving pain, reducing inflammation, and lowering fever across a range of conditions. Its broad applications and long-lasting effects make it a common choice for managing both acute and chronic conditions.
How Naproxen Works
Naproxen works by blocking the COX-1 and COX-2 enzymes, which play a key role in producing pain- and inflammation-causing substances. These enzymes help produce prostaglandins, chemicals that trigger inflammation, fever, and pain. Blocking their production reduces symptoms quickly and efficiently.

- Arthritis (osteoarthritis, rheumatoid arthritis)
- Gout attacks
- Muscle aches and back pain
- Tendinitis and bursitis

Naproxen Mechanism of Action: Explained Simply
- COX Enzyme Inhibition: Naproxen blocks COX-1 and COX-2, reducing prostaglandin production.
- Pain Relief: Less prostaglandin = reduced pain sensitivity.
- Anti-Inflammatory Effect: Swelling and redness decrease.
- Fever Reduction: Acts on the brain’s hypothalamus to regulate body temperature.
