I heard it from my pharmacist that Zyprexa tablets shouldn't be cut. They have the hard outer coating and apparently the pills are less effective if that coating is messed with. I don't think doctors know that, because I've done it lots of times. But I do notice that my 7.5 mg tablets work better than did the 5 mg with 1/2 of another 5 mg tablet. Just throwing that out there.
