Depends: The elimination of this laxative depends on the rate of movement of bowel contents. Under usual circumstances most of it should be out of the GI tract in a couple of days, a week at the most.

Milk of magnesia (magnesium hydroxide): Milk of Magnesia (magnesium hydroxide) usually takes effect (leads to a bowel movement ) in half an hour to six hours – but this is variable.

A couple of hours: If it has not worked in a couple of hours you should either take another doe or switch to something like miralax (polyethylene glycol) in combination with enemas.

Check with the dosing on the product label, since generally lower doses are used for acid reduction (1-3 TEAspoons), and higher to move the bowels (1-3 TABLEspoons).

Not for long term: Side effects include hypermagnesemia which could cause heart rhythm trouble. Hypermagnesemia occurs specially in persons with slow kidneys. Would suggest alternating it with other cathartics if you have constipation. Several options exist i.e. Senna preparations, plymerizedethylene glycol preparations called MiraLAX (polyethylene glycol) or its generic form, flaxseed oil, and prune juice. May check with pharmacist too.

Also, if you have long term constipation, you need to make sure a physician has cleared long term treatment i.e. cancer colon was excluded by a scope.
