Try Amitiza (lubiprostone): You can try to increase the dose of MiraLAX and take it on a regular basis, rather than when needed. This medication is frequently used as the purgative for colonoscopy, so if you take enough of it, it will clean you out. If you are still not satisfied with it, ask your doctor for a prescription for amitiza (lubiprostone). New prokinetic drugs will soon be available as alternative options.

Magnesium: A magnesium deficiency can contribute to constipation and is a very common mineral deficiency. Magnesium has many functions in your body, one of which is to stimulate the parasympatheric nervous system. Low magnesium can therefore increase sympathetic tone and contribute to constipation. There are many forms of magnesium available otc, including magnesium citrate, magnesium sulfate, and aspartate.
