This kind of laxative should be taken with at least 1 full glass of water or juice. Be sure to separate bulk-forming laxatives from other oral medicines by 2 hours. Stool softeners include docusate calcium and docusate sodium. These agents do not necessarily cause a bowel movement, but will soften the stool to decrease straining. Take stool softeners with a full glass of water.
Mineral oil acts as a lubricant for easier passing of the stool.
Mineral oil is not recommended for long-term use. Lactulose and sorbitol are other types of laxatives. Take these with at least 1 full glass of water or fruit juice. Stimulant laxatives include bisacodyl, or Dulcolax, magnesium preparations, phenolphthalein, cascara, and senna. Stimulants are not recommended for long-term use.
