Cyclists are big on anti-inflammatory meds, so I thought this might be of interest. Personally, I use Naproxen (Aleve).
I recently read that for Ibuprofen (brand names Advil, Motrin) to work as an anti-inflammatory, you need to take 600 mg. The typically recommended dose is one tablet (200 mg. if memory serves). At the 200 mg. level, it simply acts as an analgesic (i.e. a pain killer). So, instead of 1 tablet every 2 hours, take 3 tablets every 6 hours.
Disclaimer: The above information is 3rd hand, from an electronic design geek, well actually, a staff scientist at National Semiconductor. I read it in an article by Bob Pease in Electronic Design magazine. (He hikes in Nepal.) He was told by a doctor, and purportedly checked it out with some research of his own.
Their web page or my server is broke, otherwise I'd post a link. The article was in the Oct 14 issue, "What's All This Doctoring Stuff, Anyhow? (Part 2).
