Can You Take Naproxen with Paracetamol?
Last reviewed: · Source: US FDA drug label database
Naproxen and paracetamol can safely be taken together at standard doses — they work in different ways and are commonly combined.
Is it safe to take Naproxen with Paracetamol?
Naproxen (an NSAID) and paracetamol work through completely different mechanisms, so combining them is safe for most adults and gives better pain relief than either alone. This combination is commonly recommended for period pain, back pain, and dental pain. Keep each drug within its own daily maximum and take naproxen with food.
How do Naproxen and Paracetamol interact?
Naproxen inhibits COX enzymes peripherally, reducing inflammatory prostaglandins. Paracetamol acts mainly centrally with minimal anti-inflammatory or gastric effect. There is no pharmacokinetic interaction between them, so their effects are complementary rather than additive in toxicity.

Who should be careful?
People with stomach ulcer history, kidney disease, heart failure, or asthma triggered by NSAIDs should be careful with the naproxen component. People with liver disease or who drink heavily should be careful with the paracetamol component. Check combination cold/flu products for hidden paracetamol.
What if I've already taken Naproxen and Paracetamol?
No action needed at standard doses. Ensure you stay within 1g paracetamol per dose (max 4g/24h) and prescribed naproxen limits.

Frequently Asked Questions
Can I take naproxen and paracetamol at the same time?
Yes, at standard doses this is safe for most adults and provides better pain relief than either alone.
How should I space naproxen and paracetamol?
You can take them together or stagger them so pain relief is more continuous — e.g. naproxen every 8-12 hours with paracetamol between.
Is naproxen with paracetamol better than co-codamol?
For many types of pain, an NSAID plus paracetamol matches or outperforms low-dose codeine combinations, without opioid side effects. Discuss with your pharmacist.
Can I take naproxen, paracetamol, and ibuprofen together?
No — naproxen and ibuprofen are both NSAIDs and must not be combined. Naproxen plus paracetamol is fine.
