Naproxen: Uses, Side Effects, Dosage, Interactions and more
How Does Naproxen Work?
Naproxen works through a specific biochemical mechanism in the body. This powerful medication blocks specific enzymes called cyclooxygenase (COX-1 and COX-2). These enzymes produce compounds called prostaglandins that trigger inflammation, pain and fever when tissue gets injured.
Naproxen blocks these enzymes and:
Reduces prostaglandin production throughout the body
Decreases inflammation at injury sites
Lowers pain receptor sensitivity
Diminishes fever response

How & When to Take Naproxen?
You will get the best results from naproxen when you take it the right way.
Adults should take tablets whole with water after meals or with a snack to avoid stomach upset.
The right timing makes a difference with naproxen. Your doctor will likely suggest taking it at set times each day. Sticking to morning and evening doses often works well for twice-a-day plans. This helps maintain a consistent level of medicine in your blood throughout the day.
Take this medicine with food or a glass of milk. This protects your stomach's lining from irritation.
Stay upright for at least 10 minutes after you swallow the pill so it can reach your stomach safely.

FAQs
What is naproxen commonly used to treat?
Doctors prescribe naproxen to treat several inflammatory conditions. The medication works well for osteoarthritis, rheumatoid arthritis, juvenile arthritis, and ankylosing spondylitis. Naproxen helps with acute gout attacks, bursitis, tendinitis, and menstrual cramps. People often use it for common aches like headaches, muscle pain, dental pain, and backaches.
Is it safe to take naproxen every day?
You need medical supervision to take naproxen daily. Long-term use increases your risk of stomach ulcers that might develop without any warning signs. Doctors suggest using the lowest dose that works for the shortest time possible. You should talk to your doctor about other pain management options if you keep taking them.
What are the differences between Naproxen and Ibuprofen?
Naproxen gives you longer-lasting relief (8-12 hours per dose) than ibuprofen (4-6 hours). This makes naproxen better suited for overnight pain control. Ibuprofen starts working faster and gives you quick relief.
Can naproxen cause stomach problems or ulcers?
Yes - naproxen can create stomach ulcers even with brief use. Your risk goes up the longer you take it. Watch for signs like severe indigestion, stomach pain, heartburn, or nausea. Some ulcers develop without any warning signs. Elderly patients face higher risks of these complications.
What should I avoid while taking naproxen?
You should avoid:
Other NSAIDs like ibuprofen or aspirin
Too much caffeine
Drinking alcohol
Avoid taking it on an empty stomach
Let your doctor know about all medicines, vitamins, and supplements you take.
How long does it take for naproxen to start working?
Naproxen usually starts working within an hour. The best results come after three days of taking it twice daily. Arthritis patients get better results from consistent use rather than occasional doses.
Can I take naproxen with other painkillers?
You can safely take paracetamol with naproxen for short periods. In stark comparison to this, combining naproxen with other anti-inflammatory drugs like ibuprofen or aspirin increases side effects without better pain relief.
Is naproxen safe during pregnancy or breastfeeding?
Doctors strongly warn against naproxen use after week 20 of pregnancy because it might harm your baby's circulation and affect amniotic fluid levels. Small amounts of naproxen pass into breast milk. Most babies handle it well, but some show signs of drowsiness and vomiting. Better alternatives exist for both pregnancy and breastfeeding.
What are the common side effects of naproxen?
Users often experience digestive issues like indigestion, heartburn, stomach discomfort, nausea, or gas. Headaches, dizziness, and drowsiness happen frequently. Some people notice ear ringing or slight hearing changes. These side effects usually improve as your body adjusts to the medicine.
Can naproxen affect kidney or liver function?
Naproxen affects both organs significantly. The medication can lead to kidney failure through reduced blood flow. About 4% of long-term users show higher liver enzymes. Patients with existing kidney or liver conditions need careful monitoring and might need different doses or alternative medications.
