Naproxen typically starts working for pain relief within about 30 to 60 minutes after taking a dose. Its pain-relieving effects can last up to 7 to 12 hours. For chronic inflammation conditions, it might take about 3 days to start relieving symptoms and up to 2 to 4 weeks to reach its peak anti- inflammatory effect. The time for naproxen to fully work can vary depending on the reason for use, form of the medication, and individual factors such as other health conditions or medications being taken. It is generally advised to take naproxen with food to reduce stomach upset. In summary:
- Pain relief onset: 30 to 60 minutes
- Full pain relief peak: up to 4 hours
- Chronic inflammation relief onset: about 3 days
- Peak inflammation effect: 2 to 4 weeks
These times vary among individuals and usage context.
