Is it safe to take Naproxen with Ibuprofen?
Naproxen and ibuprofen belong to the same drug class (NSAIDs) and work in exactly the same way. Taking them together gives no additional pain relief but significantly increases the risk of stomach ulcers, gastrointestinal bleeding, and kidney damage. If one NSAID is not controlling your pain, speak to your pharmacist or GP about alternatives rather than adding a second NSAID.
How do Naproxen and Ibuprofen interact?
Both drugs inhibit COX-1 and COX-2 enzymes. Combined use means additive suppression of protective gastric prostaglandins (raising ulcer and bleed risk) and additive reduction of renal blood flow (raising kidney injury risk). Because they compete for the same target, analgesic benefit does not stack — only toxicity does.

Frequently Asked Questions
Can I take naproxen and ibuprofen together?
No. They are both NSAIDs — combining them doubles side-effect risk with no extra pain relief. Choose one, or combine one NSAID with paracetamol instead.
How long after naproxen can I take ibuprofen?
Naproxen is long-acting. Wait at least 8-12 hours after a naproxen dose before considering ibuprofen, and avoid routinely switching between them.
What can I take with naproxen for extra pain relief?
Paracetamol works through a different mechanism and can safely be combined with naproxen at standard doses for most adults.
Is naproxen stronger than ibuprofen?
Naproxen is longer-acting (8-12 hours vs 4-6 hours) and prescription doses are somewhat more potent, but head-to-head they provide broadly similar pain relief.
