Not all meds may be broke up or crushed and it would be dangerous, especially the time-released drugs. That would be what druggies do to get a high (not insinuating you are). When they are broke or crushed you would get the entire 12 hours or whatever in one blast!
A good rule of thumb is that if it doesn't have the cut line in the pill then it shouldn't be broke in half.
I didn't know this either until I went on Oxycontin and my doctor told me about it. Since I was throwing up on the full dose I thought I could only use half a dose too, Duh! I never thought about the time-release business getting affected by doing it or connecting it to what addicts do since I have never done illegal drugs. Luckily I asked the doctor "first"!!
Maybe it is ok to do with your pills, I was never on them so i don't know about them. You should first ask your doctor or pharmacist. JEAN
