"It is not uncommon to experience some abdominal discomfort and flatulence."
Laxatives may cause diarrhea, abdominal discomfort, nausea, vomiting, perianal irritation, and flatulence, as well as a number of other side effects. Prolonged use of a laxative can result in a "laxative habit," or dependence on a laxative to have a bowel movement. Some laxatives contain tartrazine (a yellow food dye), which may cause allergic-type reactions (including bronchial asthma) in susceptible individuals. Obstruction of the esophagus, stomach, small intestine, and colon has occurred when bulk-forming laxatives are administered without adequate fluid intake, or in clients with intestinal stenosis.
