The case against the case against pill-splitting.

I had thought pill-splitting was a dangerous practice born of financial desperation. People, I feared, were only getting half the dose they needed. Not necessarily, reports Ryan Nakashima of the AP. It depends on what pill you split. If you're supposed to take a 20-milligram dose of Lipitor and split the pill, that's not good. But if you buy a 40-milligram Lipitor pill and split it, that's fine. What is lovely about this is that the 40-milligram pill and the 20-milligram dose cost exactly the same.
