Naproxen for Migraine and Headache: UK Guide & Online Prescription
Naproxen is an effective first-line NSAID for mild to moderate migraine attacks — especially when taken early. This guide covers mechanism, dosing in the migraine context, when to use it vs triptans, combination therapy, and how to get a prescription online.
When to get urgent help: Call 999 or go to A&E if you have a sudden, severe headache peaking within a minute, headache with fever and a stiff neck, new weakness, slurred speech or vision loss, vomit blood or pass black, tarry poo, or have swelling of the lips, face or tongue or difficulty breathing. Contact NHS 111 or your GP (same day if possible) if you have a new headache after 50, a worsening headache, or ongoing stomach pain while taking naproxen.
▶ Naproxen for migraine at a glance
Naproxen 500mg is an NSAID effective for mild to moderate migraine, particularly when taken at the first sign of an attack. It inhibits prostaglandin production, reducing the inflammatory component of migraine pain. For moderate to severe migraine, triptans are typically more effective and should be considered first-line. Naproxen can also be combined with a triptan for enhanced relief. Prescription-only at 500mg via Access Doctor. GPhC pharmacy #9011198.

How Naproxen Treats Migraine
Naproxen is a non-selective NSAID that works by inhibiting cyclooxygenase (COX-1 and COX-2) enzymes, reducing the synthesis of prostaglandins — inflammatory mediators that sensitise cranial pain receptors and contribute to the throbbing quality of migraine pain.
Unlike simple analgesia (paracetamol), naproxen targets the inflammatory component of migraine. Its long plasma half-life of 12–17 hours means a single dose can provide relief across the duration of many migraine attacks without needing repeat dosing. This also makes it particularly useful for menstrual migraine, where attacks are often prolonged.
Naproxen for other pain conditions: This guide covers naproxen specifically in the migraine context. For musculoskeletal pain, dysmenorrhoea, gout, and arthritis, see the naproxen pain relief prescribing guide.
Naproxen vs Triptans: Which Should You Use?
| Factor | Naproxen 500mg | Triptans (e.g. sumatriptan) |
|---|---|---|
| Best for | Mild to moderate migraine; early treatment; menstrual migraine | Moderate to severe migraine; established attacks |
| Mechanism | Anti-inflammatory (COX inhibition) | Vasoconstriction + trigeminal pain pathway blockade (5-HT1B/1D agonist) |
| Onset | 1–2 hours to peak effect | 30–60 minutes (rizatriptan fastest) |
| Duration | 12–17 hours | Varies; 4–6 hours typical |
| Contraindications | Peptic ulcer, severe renal/hepatic impairment, heart failure, anticoagulants | Cardiovascular disease, uncontrolled hypertension, basilar/hemiplegic migraine |
| Combined use | Naproxen + triptan combination is superior to either alone in clinical evidence | |
For moderate to severe migraine, or when naproxen has not been fully effective, triptans such as sumatriptan are typically more effective. See the triptans comparison guide to understand your options.

Start Consultation →Dosing Guidance
| Situation | Dose | Notes |
|---|---|---|
| Acute migraine attack | 500mg at first sign; may repeat 250–500mg after 6–8 hours if needed | Maximum 1,000mg in 24 hours for migraine. OTC naproxen max 750mg/day. |
| Menstrual migraine | Perimenstrual prophylaxis regimen | Naproxen is particularly effective for menstrual migraine. For the full perimenstrual dosing protocol, see the menstrual migraine guide → |
OTC vs prescription naproxen: Naproxen 250mg is available over the counter at pharmacies only for period pain (in women aged 15–50). Prescription naproxen 500mg provides the stronger dose recommended for migraine treatment in clinical guidelines. Access Doctor can prescribe 500mg following a clinical assessment.
How to Take Naproxen During a Migraine Attack
1
Take at the very first sign
Naproxen is most effective when taken at the earliest prodromal warning sign or immediately at headache onset. Waiting until pain is severe significantly reduces response rates.
2
Take with food and water
Take with food or milk to reduce stomach irritation. Drink a full glass of water — dehydration worsens both headaches and naproxen absorption.
3
Rest in a quiet, dark environment
Once medicated, rest in a dark, quiet room if possible. Reducing sensory stimulation helps limit the headache phase severity.
4
Do not repeat too soon
If pain persists after 6–8 hours, a repeat dose is appropriate. Do not exceed the maximum daily dose prescribed.
5
Monitor frequency of use
Keep a count of how many days per month you use naproxen for headache. If it exceeds 10 days per month regularly, discuss with your prescriber — medication overuse headache risk increases above this threshold.
Naproxen + Triptan Combination Therapy
Combining naproxen with a triptan provides significantly better migraine relief than either drug alone, according to multiple randomised controlled trials. The combination addresses both the vascular component (triptan) and the inflammatory component (naproxen) of migraine simultaneously.
Sumatriptan/naproxen sodium fixed-dose combination (Treximet) is licensed in the US but not currently licensed as a combined product in the UK. However, UK prescribers can prescribe both separately to be taken together. Discuss this approach with your Access Doctor prescriber.
Who Should Not Take Naproxen
- Active or history of peptic ulcer disease — NSAIDs increase GI bleed risk
- Severe renal, hepatic, or cardiac failure
- Third trimester of pregnancy — risk of premature closure of the ductus arteriosus
- Known NSAID hypersensitivity — including aspirin-exacerbated respiratory disease
- Concurrent anticoagulant use (warfarin, DOACs) — use with extreme caution; increased bleeding risk
- Concomitant use with other NSAIDs — never take two NSAIDs simultaneously
Medication Overuse Headache (MOH)
Using any acute headache medication — including naproxen — on more than 10–15 days per month regularly can paradoxically worsen headache frequency, a condition called medication overuse headache (MOH), or rebound headache.
MOH is the most common driver of chronic migraine (15+ headache days per month). If you suspect MOH, discuss managed withdrawal with your prescriber and consider preventive treatment. See the chronic migraine guide and migraine prevention guide.
UK Safety and Prescribing Information
Key UK points for naproxen:
- Legal status: naproxen is a prescription-only medicine (POM) for migraine. The only pharmacy (P) pack is naproxen 250 mg for period pain in women aged 15–50.
- Maximum dose: follow your prescription and do not exceed the stated daily maximum. Take it with food and do not combine it with ibuprofen, aspirin for pain, or another NSAID.
- Medication-overuse headache: keep NSAIDs and other simple painkillers to fewer than 15 days a month, and triptans to fewer than 10 days a month.
- Interactions: tell your prescriber if you take anticoagulants, low-dose aspirin, SSRIs, steroids, lithium, methotrexate or blood pressure medicines, which raise bleeding or kidney risks.
- Supply: Access Doctor supplies MHRA-licensed UK medicines, dispensed by a GPhC-registered pharmacy (#9011198) after a prescriber’s assessment. Buying prescription-only medicines without a prescription is illegal in the UK.
Pregnancy and breastfeeding: Avoid naproxen in pregnancy unless a doctor advises it, and do not use it in the third trimester; paracetamol is the preferred painkiller. Naproxen is not usually used while breastfeeding — ibuprofen is generally preferred. Check with your GP, midwife or pharmacist.
Driving: naproxen can occasionally cause dizziness, drowsiness or blurred vision. Do not drive until you know how it affects you.
NHS: migraine medicines are available on NHS prescription. Charges apply in England unless you are exempt; prescriptions are free in Scotland, Wales and Northern Ireland.
Frequently Asked Questions
How does naproxen help with migraines?
Naproxen inhibits COX-1 and COX-2 enzymes, reducing prostaglandin production. This reduces the inflammatory component of migraine pain, decreases the throbbing quality, and has anti-inflammatory effects on sensitised cranial blood vessels. Its long half-life (12–17 hours) means a single dose often covers the duration of an attack.
Is naproxen better than ibuprofen for migraine?
Both are NSAIDs and work similarly. Naproxen has a longer half-life (12–17h vs ibuprofen 2h), meaning fewer repeat doses during a prolonged attack. Prescription naproxen 500mg is a stronger dose than standard OTC ibuprofen 400mg. Either can be combined with a triptan for moderate–severe attacks.
Can naproxen be taken with sumatriptan?
Yes. Combining naproxen with a triptan produces better migraine relief than either drug alone in clinical trials. This is particularly useful for prolonged attacks. Always follow prescriber instructions and disclose your full medication list.
How quickly does naproxen work for a migraine?
Naproxen reaches peak absorption within 1–2 hours. For best results, take it at the very first sign of a migraine attack, before pain becomes severe. Early treatment significantly improves response rates.
Who should not take naproxen?
Naproxen is not suitable for people with active peptic ulcer disease, severe renal or hepatic impairment, severe heart failure, known NSAID hypersensitivity, or those in the third trimester of pregnancy. Use with caution in people taking anticoagulants. A clinical consultation screens for contraindications before prescribing.
What is medication overuse headache?
Medication overuse headache (MOH) develops when any analgesic, including naproxen, is used on more than 10–15 days per month regularly. MOH causes paradoxical worsening of headache frequency. If you are using headache medication very frequently, discuss this with a prescriber.
Is naproxen prescription-only in the UK?
Mostly, yes. Naproxen for migraine and other pain is a prescription-only medicine in the UK. The only exception is a pharmacy pack of naproxen 250mg tablets licensed for period pain in women aged 15 to 50, which a pharmacist can sell without a prescription. Your GP or a registered online prescriber can prescribe it after checking it is safe for you.
