From the Guidelines
The duration of naproxen use that could cause neurocognitive changes is not precisely established, but potential risks generally increase with long-term use (months to years) rather than short-term use. Most patients taking naproxen as directed for acute pain (typically 7-14 days) are unlikely to experience significant neurocognitive effects. However, elderly patients and those with pre-existing cognitive impairment may be more susceptible to these effects even with shorter durations of use. Naproxen, like other NSAIDs, may affect cognition through several mechanisms including altering cerebral blood flow, increasing oxidative stress, or affecting neurotransmitter systems 1.
Key Considerations
- The exact duration of naproxen use that leads to neurocognitive changes is not well-defined, but long-term use is associated with higher risks 1.
- Elderly patients and those with pre-existing cognitive impairment are at higher risk of neurocognitive effects from naproxen use.
- Naproxen may impact cognition through various pathways, including changes in cerebral blood flow and oxidative stress.
- Patients taking naproxen should be aware of potential cognitive changes, such as confusion, memory problems, or difficulty concentrating, and consult their healthcare provider if these symptoms occur.
Recommendations for Use
- For patients requiring short-term pain management, naproxen can be used as directed without significant concern for neurocognitive effects.
- For patients needing long-term pain management, alternative pain management strategies should be considered to minimize potential neurocognitive risks 1.
- Periodic cognitive assessments may be beneficial for patients on long-term naproxen therapy to monitor for any adverse effects on cognition.

The FDA drug label does not answer the question.
From the Research
Neurocognitive Changes and Naproxen
- The exact duration of naproxen use required to cause neurocognitive changes is not specified in the provided studies 2, 3, 4, 5, 6.
- A study published in 2003 found that treatment with naproxen for 1 year did not slow cognitive decline in patients with mild-to-moderate Alzheimer's disease 3.
- Another study published in 2017 found that acute administration of naproxen (750 mg) had no effect on memory in healthy young adults 6.
- There is no direct evidence in the provided studies to suggest a specific duration of naproxen use that causes neurocognitive changes.
- The studies primarily focus on the effects of naproxen on Alzheimer's disease, acute pain, and gastrointestinal and cardiovascular adverse events, rather than neurocognitive changes in general 2, 3, 4, 5.
Relevant Studies
- A 2002 study discussed the potential of selective COX-2 inhibitors and nonselective NSAIDs, such as naproxen, in treating Alzheimer's disease 2.
- A 2020 study reviewed the efficacy and safety of naproxen for acute pain, but did not address neurocognitive changes 5.
- A 2022 study examined the gastrointestinal and cardiovascular adverse events associated with NSAIDs, including naproxen, but did not discuss neurocognitive effects 4.
