Hi, I was at the ER today and the doctor prescribed Naprosyn (naproxen) 375 mg 3 times a day. I already have Naproxen at home but it is 500 mg. Can I take that?

OK to take 500, Although it's always best to err on the side of caution. With anti-inflammatory medications, take the lowest dose that gives you relief. Chronic use of anti-inflammatory drugs (NSAIDS) can be rough on the kidneys. Taking a slightly higher dose than prescribed should be OK for a short period.
