What is Naproxen?

Naproxen is a powerful pain relief medication classified as a non-steroidal anti-inflammatory drug (NSAID). It belongs to the same group as ibuprofen, aspirin, and diclofenac but provides stronger anti-inflammatory benefits than aspirin and ibuprofen while carrying fewer risks compared to diclofenac.

This medication is commonly used to relieve pain caused by inflammation, such as sprains, strains, and arthritis. It is particularly effective for conditions like osteoarthritis, rheumatoid arthritis, and juvenile arthritis. Naproxen is available for adults over 18 years old and comes in 250mg or 500mg tablet strengths, with each pack containing 56 tablets.

To protect your stomach, always take Naproxen with food. If you need long-term treatment (more than two weeks), a stomach-protective medicine like Omeprazole may be recommended.

You can purchase Naproxen online from Courier Pharmacy after completing a quick online consultation.

What is the active ingredient in Naproxen 500mg Gastro-Resistant Tablets?

Naproxen 500mg Gastro-Resistant Tablets contain Naproxen 500mg as the active ingredient. This anti-inflammatory medicine is designed to provide effective pain relief while reducing inflammation and stiffness.

You can purchase Naproxen online from Courier Pharmacy after completing a quick online consultation.

What is Naproxen used for?

Naproxen is a non-steroidal anti-inflammatory drug (NSAID) that helps reduce pain and inflammation. It works by lowering the levels of hormones that cause swelling and discomfort. This medication is commonly used to treat:

  • Muscle pain
  • Rheumatoid arthritis
  • Menstrual cramps
  • Gout

You can buy Naproxen online from Courier Pharmacy after completing a short online consultation.

How does Naproxen work?

Naproxen reduces pain and inflammation by blocking cyclooxygenase (COX) enzymes, which are responsible for producing prostaglandins. These chemicals contribute to swelling and discomfort at injury sites. By lowering prostaglandin levels, Naproxen helps relieve symptoms of arthritis, muscle pain, and other inflammatory conditions.
