So, if you don't keep up with health news I do because of my medically related graduate work. There's been a lot of news on the arthritis drugs
Vioxx,
Celebrex and now
Aleve (Naproxen). All these drugs have had studies come out in the last few months showing they bring an increase of risk of cardiovascular disease (heart attack, stroke, etc).
I'm not trying to downplay the risk, but very few articles actually site the risk to a given person. For most people, the risk of having cardiovascular event in the next 3 years is less than one percent. Which means an increase of 2.5 times the norm (Vioxx) is still minimal and barely statistically significant (unless you are at high CV risk).
I was happy to stumble upon
this article. Basically, it reports that a some people think the risk involved is well worth the amount of pain relief. The actions of Merck (maker of Vioxx) have probably caused more of a media frenzy than the results deserve, and may mean the demise of a whole family of drugs (COX inhibitors) that otherwise would be effective.
Bottom Line: Anything you put into your body that is not natural (whether it's a hip replacement or tylenol) will result in some kind of effect not exclusive to the desired one. Get used to it, and weigh the risk.
