I have a history of migraines and recently got this from my doctor to take. Well I have taken it about 2-3 wks now. I take it every 12 hours for grinding/jaw pain/daily headaches til I figure out what is causing them. The usual adult dose for pain is 250 every 6 to 8 hours or 500 mg twice daily using regular naproxen tablets. The usual dose for Naprelan controlled release tablets is 750 to 1000 mg given once daily. For EC-Naprosyn, the usual dose is 375-500 mg twice daily. Naproxen is not a good drug for treating migraine at the doses of 500 mg or 825 mg used in the studies we found. Abstract Background: Migraine is a common, disabling condition and a burden for the individual, health services, and society. We included six studies using naproxen 275 mg, 500 mg, or 825 mg to treat attacks of moderate or severe pain intensity. Overall, 1241 participants took naproxen (275 mg to 825 mg), 229 took sumatriptan 50 mg, 173 took naratriptan 2.5 mg, and 1092 took placebo. The Naproxen 500 mg tablet is a powerful pain reliever. Many people who deal with severe pain daily swear by it. They understand the risks involved, and they accept those risks in exchange for the pain relief they receive. Headaches should usually go away after the first week of taking naproxen. Talk to your doctor if they last longer than a week or are severe.
