Last reviewed July 2026
Who is this for?
Naproxen is a painkiller and anti-inflammatory drug that works by reducing the chemicals in your body that cause pain, swelling, and fever. It belongs to the same family as ibuprofen but lasts longer in the body.
Inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby decreasing pain, inflammation, and fever.

If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not take a double dose to make up for the one you missed.
Buy only from trusted pharmacies, avoiding roadside or market sellers, as fake drugs are common in Nigeria. Do not use naproxen for long periods without a doctor's supervision, as it can damage your stomach and kidneys over time. In Nigeria this drug is available as Cedax Tablet and Naroxine Tablet, so make sure you check the expiry date before buying.
Avoid taking naproxen together with other painkillers like ibuprofen or diclofenac as this increases the risk of stomach bleeding. If you are on blood pressure drugs like lisinopril or amlodipine, naproxen can reduce their effect, so inform your doctor. Avoid drinking alcohol while taking naproxen as it increases the chance of stomach ulcer and bleeding.
