Follow up on an earlier question: Finally, the PF people at Pfizer told me that while the firm recommends that the Lipitor pills NOT be broken in half or cut in half, they do say that it is perfectly okay to do this under doctor's prescription or recommendation, and that there is no negative downside at all to cutting Lippy in half. However, they do recommend not breaking them if no need to. So there. Case solved. Happy camper I am.
