Naproxen is a longer-acting anti-inflammatory, usually taken twice a day rather than three or four times. That makes it a common choice for ongoing conditions like arthritis and gout, where steady cover matters more than a quick effect.

What it is used for

Naproxen treats pain and inflammation in arthritis, gout attacks, muscle and joint injuries, back pain and period pain. It is also used for some other inflammatory conditions.

Compared with ibuprofen it lasts longer, which suits pain that is present all day. The trade-off is that the risks common to all anti-inflammatories still apply, and a longer-acting medicine means longer exposure.

How to take it

Take exactly as prescribed — usually once or twice a day, with or just after food. Gastro-resistant tablets must be swallowed whole and not crushed or chewed.

Take the lowest dose that controls your symptoms, for the shortest sensible period. For gout, a short higher-dose course is normal. For arthritis, ongoing use should be reviewed periodically by your GP.

Many people prescribed naproxen long term are also given a stomach-protecting medicine such as omeprazole or lansoprazole. Take it — it is there for a reason, not as an optional extra.

Side effects and risks

Indigestion, heartburn, nausea and stomach pain are the common ones. Taking it with food helps but does not remove the risk.

Like other anti-inflammatories, naproxen carries a small increase in the risk of heart attack and stroke, particularly at higher doses and with longer use — which is another reason for periodic review.

Who should take extra care

Avoid from 20 weeks of pregnancy onwards. Do not take alongside ibuprofen or other anti-inflammatories — that doubles the risk without improving pain relief.

Frequently asked questions

Is naproxen stronger than ibuprofen?
It is longer-acting rather than simply stronger — usually twice daily instead of three or four times. Which suits you better depends on the type and pattern of pain.
Why have I been given omeprazole with naproxen?
To protect your stomach lining. Anti-inflammatories can cause ulcers and bleeding, and a stomach-protecting medicine substantially reduces that risk with long-term use.
Can I take naproxen with ibuprofen?
No. Combining anti-inflammatories increases the risk of stomach bleeding and kidney problems without improving pain relief.
Can I buy naproxen over the counter?
Only a specific low-dose product for period pain in women aged 15 to 50 is available from pharmacies. Other uses need a prescription.
