How to take this drug

Adults usually take 250mg to 500mg twice daily (morning and evening). Always take naproxen with food or a glass of milk to protect your stomach. Swallow the tablet whole with water. Do not take more than 1,250mg in a day. Start with the lowest dose that controls your pain.

What if I Miss a Dose?

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.

What to watch out for

Buy only from trusted pharmacies — avoid 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 — make sure you check the expiry date before buying.

Common Side Effects

Stomach pain or upset
heartburn or indigestion
feeling dizzy
mild headache
feeling bloated or gassy

Serious Side Effects

Black or bloody stool (this could mean bleeding in your stomach — go to the hospital immediately)
sudden chest pain or difficulty breathing
severe skin rash or swelling of the face and throat (this could be a dangerous allergic reaction)

Drug Interactions

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 — inform your doctor. Avoid drinking alcohol while taking naproxen as it increases the chance of stomach ulcer and bleeding.
