▶ Quick summary
Naproxen is a prescription NSAID used for musculoskeletal pain, gout, arthritis, period pain, and other inflammatory conditions. Standard dose: 250–500mg twice daily with food. Longer-acting than ibuprofen — twice-daily dosing is sufficient for most conditions. A proton pump inhibitor (PPI) should be co-prescribed to protect the stomach. Available via online consultation at Access Doctor. GPhC pharmacy #9011198.
250–500mg
Standard dose twice daily with food
12–17h
Plasma half-life — twice-daily dosing sufficient

Conditions Naproxen Is Prescribed For
Naproxen is licensed and prescribed in the UK for conditions where inflammation is driving the pain. It is more effective than paracetamol for these conditions because it acts at the source of the problem — the inflammatory process itself — rather than simply modulating pain perception.
- Musculoskeletal pain — sprains, strains, back pain, neck pain; reduces both pain and the swelling that slows recovery
- Acute gout — NICE first-line treatment for acute gout attacks; rapidly reduces the intense inflammation caused by uric acid crystals in the joint
- Osteoarthritis — reduces joint pain and stiffness; most effective during inflammatory flares
- Rheumatoid arthritis — reduces joint inflammation, morning stiffness, and pain
- Period pain (dysmenorrhoea) — particularly effective because menstrual pain is prostaglandin-mediated; naproxen directly reduces prostaglandin production
- Tendinitis and bursitis — reduces peri-articular inflammation; commonly prescribed for shoulder, elbow, and knee tendinopathy
- Post-operative and post-procedure pain — used alongside paracetamol in multimodal analgesia
Dosing and How to Take Naproxen
| Indication | Typical dose | Notes |
|---|---|---|
| General musculoskeletal pain / arthritis | 250–500mg twice daily with food | Take morning and evening; always with food or immediately after a meal |
| Acute gout | 750mg initially, then 250mg every 8 hours | Continue until attack resolves, typically 7–10 days; with food |
| Period pain (dysmenorrhoea) | 500mg at onset, then 250mg every 6–8 hours | During painful days only; start at first sign of pain for best effect |
| Maximum dose | 1,000mg daily (general use); up to 1,250mg day 1 only for acute gout (dose then reduces) | Do not exceed without prescriber review |
Always take naproxen with food. NSAIDs inhibit prostaglandins in the gastric mucosa. Without food, naproxen significantly increases the risk of stomach irritation, ulceration, and bleeding. This is the most important safe-use rule for naproxen.
Gastric Protection: The PPI Requirement
NICE guidelines and standard UK clinical practice recommend co-prescribing a proton pump inhibitor (PPI) such as omeprazole or lansoprazole with naproxen for most patients. NSAIDs reduce the stomach’s natural protective prostaglandins, increasing the risk of ulceration and gastrointestinal bleeding. A PPI counters this by reducing stomach acid production.
PPI co-prescribing is particularly important if you are over 65, taking anticoagulants, have a history of peptic ulcer disease, or are taking naproxen for more than a few days.
When you complete a naproxen consultation at Access Doctor, our prescribers will assess whether a PPI is appropriate and can prescribe both together if indicated.
Who Should Not Take Naproxen
- Active peptic ulcer disease or GI bleeding history — NSAIDs significantly worsen or trigger GI bleeding
- Severe renal impairment — NSAIDs reduce renal blood flow; can precipitate acute kidney injury in at-risk patients
- Heart failure — NSAIDs cause sodium and water retention; contraindicated in significant cardiac failure
- Recent heart attack or stroke — avoid NSAIDs in the period following a heart attack or stroke — discuss timing with your prescriber
- Third trimester of pregnancy — risk of premature closure of the ductus arteriosus and impaired renal function in the neonate; contraindicated
- NSAID hypersensitivity / aspirin-sensitive asthma — naproxen is contraindicated if previous allergic reaction to any NSAID
- Severe hepatic impairment — use with caution; avoid in severe liver disease
Stop naproxen and seek urgent care if you develop: dark or tarry stools, vomiting blood or material resembling coffee grounds, severe abdominal pain, or swollen ankles with reduced urine output. These may indicate GI bleeding or kidney problems.
Drug Interactions
| Drug/class | Interaction |
|---|---|
| Anticoagulants (warfarin, DOACs) | Increased bleeding risk — NSAIDs inhibit platelet function; co-prescribe PPI and monitor INR if unavoidable |
| Other NSAIDs (ibuprofen, diclofenac, aspirin) | Never combine two NSAIDs — multiplies GI risk with no additional benefit |
| SSRIs / SNRIs (antidepressants) | Increased GI bleeding risk when combined with NSAIDs — PPI strongly recommended |
| Antihypertensives (ACE inhibitors, ARBs) | NSAIDs can reduce antihypertensive efficacy and increase risk of renal impairment |
| Lithium | NSAIDs reduce renal lithium clearance; can raise lithium levels to toxic range |
| Diuretics | NSAIDs reduce diuretic efficacy; increased risk of renal impairment |
| Methotrexate | NSAIDs can reduce methotrexate excretion; risk of toxicity — avoid combination or seek specialist advice |
Naproxen vs Other Pain Relief Options
| Medicine | Best for | Duration | Key difference |
|---|---|---|---|
| Paracetamol | Non-inflammatory pain, fever, headache | 4–6 hours | No anti-inflammatory action; no stomach risk; safe in pregnancy |
| Naproxen | Inflammatory pain, gout, arthritis, dysmenorrhoea | 8–12 hours (twice daily dosing) | Longer-acting than ibuprofen; NICE first-line for gout |
| Ibuprofen 600mg | Inflammatory pain, period pain, dental pain | 4–6 hours (three times daily) | Faster onset; more frequent dosing; lower risk of CV events vs naproxen at equivalent doses per some studies |
| Diclofenac gel | Localised joint or soft tissue pain | Variable | Topical — fewer systemic side effects; no GI risk; useful for osteoarthritis of accessible joints |

Start Consultation →Frequently Asked Questions
What pain conditions is naproxen prescribed for?
Naproxen is prescribed for conditions driven by inflammation: musculoskeletal injuries (sprains, strains, back pain), gout, osteoarthritis, rheumatoid arthritis, period pain (dysmenorrhoea), tendinitis, and bursitis. It is more effective than paracetamol for these conditions because it reduces the inflammation causing the pain.
What is the dose of naproxen?
The standard prescription dose for most pain conditions is 250–500mg twice daily, taken with food. For acute gout, higher doses are used short-term (750mg initially, then 250mg every 8 hours). Maximum 1,000mg/day for general use. Always follow your prescriber’s instructions.
Do I need a PPI with naproxen?
NICE guidance and standard UK clinical practice recommend co-prescribing a PPI (such as omeprazole or lansoprazole) with naproxen for most patients. NSAIDs reduce the stomach’s natural protective prostaglandins, increasing ulcer and bleeding risk. A PPI counteracts this.
Can I take naproxen with paracetamol?
Yes — naproxen and paracetamol work by different mechanisms and can be safely combined for better pain relief. Never take naproxen alongside ibuprofen, diclofenac, or any other NSAID.
How long does naproxen take to work?
Initial pain relief typically begins within 1 hour. For chronic inflammatory conditions such as arthritis, full anti-inflammatory benefit builds over several days of regular dosing. Gout attacks typically show meaningful improvement within 24–48 hours.
Who should not take naproxen?
Naproxen should be avoided if you have active peptic ulcer disease, severe kidney or liver disease, heart failure, recent heart attack or stroke, aspirin-sensitive asthma, or are in the third trimester of pregnancy. Use with caution in people over 65 and those taking anticoagulants.
