Laxatives are medicines that help resolve constipation or empty the bowel of fecal matter before procedures or surgery involving the lower bowel. There are several different types available (see differences below) and each type works in a particular way.
Bulk-forming laxatives are the safest type and can take 12 hours to three days to work. Stimulant laxatives work within 6 to 8 hours and should be used only for a short time. If you are experiencing constipation, you may have tried lifestyle changes, such as eating more fiber and increasing your fluids.
