A friend's doc told her that she could cut WB SR in half. I called my pharmacy & the pharmacist said that I could (even though the bottle says not to crush or chew). Today I spoke to a diff pharmacist at the same pharmacy & he said not to split the pill. Some posts say when an SR version is cut in half that it becomes Instant Release, but some say do not do it. This morning I did cut my pill in half & took it. I think that I will not do it again. I also took 10 mg Celexa. I don't understand why some docs & pharmacists say that the SR version can be cut in half. Thanks.
