What is Naproxen? An Essential Guide to a Powerful Pain and Inflammation Reliever
What Is Naproxen? An Essential Guide to Naproxen Uses, Dosage and Side Effects
Medical disclaimer: This article is for informational purposes only. Prescription naproxen requires clinical assessment. Our prescribers are GPhC-registered pharmacist independent prescribers.
Naproxen is one of the most trusted and clinically well-evidenced non-steroidal anti-inflammatory drugs (NSAIDs) in the UK. Used for everything from acute gout attacks to chronic arthritis, period pain, and musculoskeletal injuries, naproxen works by targeting the inflammatory process at its root rather than simply numbing pain signals. This comprehensive guide covers everything you need to know — how it works, what it treats, dosage guidance, side effects, and how to get a prescription online.

The key distinction between naproxen and simple analgesics like paracetamol lies in where they act. Paracetamol primarily works centrally — reducing the brain’s perception of pain signals. Naproxen acts peripherally — reducing the inflammatory process at the site of injury or disease that is generating the pain signals in the first place.
If you have gout, arthritis, or a muscle strain, the pain arises from local inflammation — prostaglandins sensitising pain receptors and causing swelling. Naproxen reduces prostaglandin production, directly addressing the source. Paracetamol cannot do this. For an in-depth comparison, see our guides to paracetamol and ibuprofen 600mg.
Naproxen’s Mechanism: COX Inhibition
What Conditions Does Naproxen Treat?
- Acute gout — NICE first-line treatment; rapidly reduces uric acid crystal-induced joint inflammation
- Rheumatoid arthritis — reduces joint pain, stiffness, and swelling
- Osteoarthritis — reduces arthritic joint pain; use at lowest effective dose
- Back pain — effective for acute and subacute back pain with inflammatory features
- Period pain — highly effective because menstrual cramping is prostaglandin-driven
- Sprains and strains — reduces pain and swelling from soft tissue injuries
- Tendinitis and bursitis — reduces peri-articular inflammation
Dosage and How to Take Naproxen Safely
| Indication | Typical Dose | Duration |
|---|---|---|
| General pain / arthritis | 250–500mg twice daily with food | As directed; regular review needed for prolonged use |
| Acute gout | 750mg initially, then 250mg every 8 hours | Until attack resolves (typically 7–10 days) |
| Period pain | 500mg initially, then 250mg every 6–8 hours | During painful days only |
| Maximum dose | 1000mg per day (general); 1250mg per day for gout short-term | — |
Naproxen has a longer half-life than ibuprofen (12–17 hours vs 2 hours). This means it needs to be taken less frequently — twice daily versus 3–4 times daily for ibuprofen — and provides more consistent, sustained anti-inflammatory effect.
Side Effects and Safety Considerations
- Gastrointestinal — most common; stomach pain, nausea, heartburn, ulceration, GI bleeding (use with food; consider PPI)
- Cardiovascular — small increased risk of heart attack and stroke with long-term use; avoid in people with established CVD
- Renal — may reduce kidney blood flow; use with caution in kidney disease or dehydration
- Blood pressure — NSAIDs can raise blood pressure; monitor in hypertensive patients
- Dizziness/drowsiness — avoid driving if affected
Red flag symptoms: Stop naproxen and seek urgent medical attention if you develop: dark or tarry stools, vomiting blood, severe abdominal pain (GI bleeding), swelling of the face, lips or throat (allergic reaction), or sudden difficulty breathing.

What is naproxen used for?
Naproxen is used for conditions where inflammation causes pain: gout, rheumatoid arthritis, osteoarthritis, period pain, back pain, tendinitis, bursitis, and musculoskeletal sprains. It works by reducing prostaglandin production — targeting the cause of inflammation rather than masking pain.
How does naproxen work?
Naproxen inhibits COX-1 and COX-2 enzymes, blocking prostaglandin synthesis. Prostaglandins sensitise pain receptors, mediate inflammation, and produce fever. By reducing their production, naproxen directly reduces pain, swelling, and heat.
How long does naproxen take to work?
Most people experience initial pain relief within 1 hour of taking naproxen. Full anti-inflammatory effect for chronic conditions builds over 2–3 days of regular dosing.
What are the side effects of naproxen?
Common side effects include headache, dizziness, drowsiness, and stomach irritation. More serious risks with prolonged use include peptic ulcers, GI bleeding, elevated blood pressure, and kidney strain. Taking with food and using a PPI significantly reduces stomach risk.
Should I take naproxen with food?
Yes. Always take naproxen with food or immediately after a meal. This significantly reduces the risk of stomach irritation and ulceration.
Is naproxen available over the counter in the UK?
Lower-dose naproxen (250mg) is available OTC for short-term pain in adults. Prescription-strength doses (up to 500mg twice daily) require a clinical consultation. Access Doctor provides online consultations for prescription naproxen with next-day delivery.
Can naproxen be used for gout?
Yes. Naproxen is a first-line treatment for acute gout attacks in UK clinical guidelines. It rapidly reduces the intense inflammation triggered by uric acid crystals in the joint. A short, high-dose course is typically prescribed.
Can I drive while taking naproxen?
Naproxen can cause dizziness and drowsiness in some patients. If affected, do not drive or operate machinery.
