Accidental overdose: Phillip291, 12 aleve in a 12 hour period is too many! I had a patient do the same thing trying to get rid of hip pain and end up in the hospital with very bad GI bleeding. Going to the hospital would be the best but if she won't then take her aleve away and keep an eye on her for the next 24 hours for bleeding. Have her drink 2 liters of water to flush her kidneys. Its too late for zantac. ...Read more

Took 2 aleve (naproxen) this morning. then 12 hours later to 2 more by mistake. will I be OK?

Yes: The usual dosage for this medication is one tablet twice daily. Doubling the dose accidentally will not be harmful, however, you should not continue the higher dose without notifying your primary care physician.

I've taken 12 220mg aleve (naproxen) in the past four hours to aleviate a pain in my tooth. Should I be okay?

NO: You have actually taken a fairly toxic dose of naproxyn sodium: 12x 220mg= 2640 mg ( 2.64 grams). Maximum daily dose of this medicine is 1,500 mg ( 500 mg 3x/day)- in severe cases. Go to the ER now- you have inadvertently poisoned yourself. ...Read more

Can I take 2 ibuprofen 12 hours after I've taken an Aleve (naproxen)?

Can I take 2 ibuprofen 12 hours after I've taken an Aleve (naproxen)?

Bad idea: do not mix NSAIDS: use either Aleve (naproxen) or Advil- not both: taking a double dose of NSAIDS can lead to gastric irritation/bleeding. If you have inadvertently taken both, wait 8 hrs and flood yourself with 8-10 glasses of water. ...Read more

How many hours after taking naproxen can u take aleve?

How many hours after taking naproxen can u take aleve?

12 hours: Aleve is naproxen, so you are talking about the same drug. The dosing interval is 12 hours. If you need something extra for discomfort you can take 2 tylenol (acetaminophen) every 6 hours for the next 2-3 days only. Beyond that, consult your doctor about management. ...Read more
