It is important to be educated regarding the variety of laxatives for constipation. Whether you suffer from constipation-predominant irritable bowel syndrome (IBS-C), chronic idiopathic constipation (CIC), or just find yourself temporarily bound up, you need to know about the safety and effectiveness of each type of laxatives before making your selection. As you can see, there are a variety of different options -- the information below will help you to decide which one is right for you.

Bulk Laxatives

Bulk laxatives use the power of fiber to soften the stool and stimulate a bowel movement. There are three basic types of bulk laxatives, each of which uses a different ingredient: psyllium, calcium polycarbophil, or methylcellulose. As with all laxatives, it is essential to drink plenty of fluids when using bulk laxatives.

Osmotic Laxatives

Osmotic laxatives work by increasing the amount of fluid secreted within the intestines, resulting in softer and easier-to-pass stools. The three major osmotic laxatives are Miralax, Lactulose, and Milk of Magnesia.

Herbal Stimulant Laxatives

A variety of herbs have a reputation for having laxative effects. Aloe latex, cascara sagrada, frangula, rhubarb, and senna are all examples of herbal stimulant laxatives. Due to possible health concerns, herbal stimulant laxatives are recommended to be used on a short-term (no longer than one week) basis only. For more information on safety concerns of these natural remedies:

Stimulant Laxatives

Stimulant laxatives work by speeding up the movement of intestinal muscles, thus inducing a bowel movement. Many of the well-known products sold in your drug store are stimulant laxatives, including Carters Little Pills, ExLax, and Dulcolax. Stimulant laxatives are generally best-used as a short-term treatment for constipation.

Stool Softeners

Stool softeners do just what they say they do -- they soften the stool so that it is easier to pass. Most stool softeners contain a medication called docusate. Brand names include Colace, Doxinate, and Fleet Sof-Lax. Stool softeners are generally recommended for short-term use, but can be taken for a longer time with the blessing of your physician.
