What kind of laxative is best?
Use occasionally. Bulk-forming laxatives, which contain psyllium or other fiber (such as Metamucil, Fibercon, Citrucel and generics), are effective, gentle-acting and less likely to produce side effects than stimulants. Some also have sorbitol or other sugar alcohols, which have laxative properties. Lubricating laxatives (such as mineral oil and glycerin) make stool oily and thus easier to pass. Some stool softeners also work this way. Osmotic laxatives (such as milk of magnesia) contain magnesium salts or sodium biphosphate. They are fast-acting. Follow directions, and don’t take large doses.
