About Naprosyn EC Tablets

Naprosyn EC Tablets contain naproxen, a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain, swelling, and inflammation. Naprosyn works by reducing the substances in the body that cause pain and inflammation, helping to improve mobility and comfort in inflammatory conditions.

Naprosyn 250mg & 500mg EC Tablets are commonly prescribed for adults to manage musculoskeletal pain, arthritis, gout, and period pain. The enteric-coated (EC) formulation helps protect the stomach by allowing the tablet to dissolve in the intestine rather than the stomach.

Naprosyn EC Tablets are available in two strengths:

  • Naprosyn 250mg Enteric-Coated Tablets
  • Naprosyn 500mg Enteric-Coated Tablets
