Ibuprofen and naproxen are both NSAIDs (nonsteroidal anti-inflammatory drugs) and should not be taken together. Combining two NSAIDs significantly increases the risk of gastrointestinal bleeding, stomach ulcers, and kidney damage without providing meaningful additional pain relief.
How This Interaction Works (Mechanism)
Both ibuprofen and naproxen inhibit COX-1 and COX-2 enzymes. Taking them together doubles the COX inhibition in the GI tract, dramatically reducing the protective prostaglandin lining of the stomach. This leads to a much higher risk of peptic ulcers and GI hemorrhage. Both drugs also reduce renal blood flow through prostaglandin inhibition, and combining them can cause acute kidney injury.

Never take ibuprofen and naproxen at the same time. Choose one NSAID and use it at the lowest effective dose for the shortest period. If one NSAID is not providing adequate relief, talk to your doctor about alternative pain management strategies rather than adding a second NSAID. If you need to switch from one to the other, wait at least 12 hours.
