According to Metamucil's Online FAQ, the product does not contain any chemicals that "cause [the] immediate evacuation" of the bowels that characterize incontinence. Rather, Metamucil usually relieves constipation with 12 to 72 hours. However, if you are suffering from constipation, a considerable amount of shrunken, dessicated feces has collected in your large intestine. As the soft, psyllium-containing waste enters the large intestine, catastalsis forces it through the passage where it eventually meets the dessicated feces. These continuous, wavelike contractions push the soft feces into the hard form, filling the intestines and forcing the hard stool toward the anus. As this new feces builds up behind the slow, hard feces, so too does the pressure against the anus. If the pressure exceeds the strength on the anal sphincter (a ring of muscles that opens and closes the anus), incontinence will result.
It makes for one hell of a Cleveland Steamer
