A. Mishna Berura (328: 55- 56) seems to prohibit. However, some Poskim permit with a shinui or a change from the usual way to do it, when the water used is pure and does not contain any medical substances. The reason being is that it is not a cure but rather only a cleansing of the lower bowel. (Daas Torah (328: 49), Shemiras Shabbos K' 34: 11. permits even without a shinui. See similar in Piskei Teshuvos 328).
Horav Shlomo Miller's opinion is that it could be done when needed and only when using only clear water without any medical additives.
