How does naproxen work?
Naproxen blocks enzymes (COX-1 and COX-2) that produce prostaglandins, substances that cause pain, swelling, and inflammation. By reducing prostaglandins, naproxen helps relieve discomfort and stiffness.

Who can take naproxen?
Most adults and children over 12 can take naproxen for pain relief. However, it is usually prescribed rather than bought over the counter.
Who might not be able to take naproxen?
Naproxen may not be suitable if you:
- Have a history of stomach ulcers or bleeding
- Have heart, liver, or kidney disease

- Are pregnant, especially in the third trimester
Speak to a doctor if you’re unsure whether naproxen is safe for you.
Can I take naproxen if I’m pregnant or breastfeeding?
Naproxen isn’t usually recommended during pregnancy, especially in the later stages, as it may affect the baby’s circulation and kidney function. If you’re breastfeeding, check with your doctor before taking it.
What if I miss a dose?
If you forget a dose, take it as soon as you remember. If it’s nearly time for your next dose, skip the missed one – don’t take two doses at once.

Naproxen is highly effective for reducing pain and inflammation. It usually starts working within an hour, and its effects can last up to 12 hours, making it useful for long-term pain management.
What should I do if I take too much?
Taking too much naproxen can cause stomach pain, nausea, vomiting, drowsiness, and serious complications like internal bleeding. Seek immediate medical help if you’ve taken more than the prescribed dose.
What dose of naproxen is usually taken?
The usual dose depends on what it’s being used for:
- Arthritis and long-term pain: 250mg to 500mg twice daily
