Many people use over-the-counter laxatives to treat occasional constipation. Some of the most popular laxatives used include products that contain magnesium salts. Although the use of laxatives can acutely relieve symptoms of constipation, overuse can lead to the development of chronic constipation. Patients should exercise caution whenever using over-the-counter laxatives.
Constipation
Constipation typically involves difficulty in the passing of bowel movements. Symptoms often include hard stools, excessive straining, abdominal pain, rectal bleeding and irregular bowel movements. There are many causes of constipation including abnormal intestinal function, medications and diet. If left untreated, constipation can result in bowel obstruction and fecal impaction.
Osmotic Laxatives for Occasional Constipation
Many people will experience occasional episodes of constipation. In most cases, acute constipation can be treated with over-the-counter laxatives. Osmotic laxatives that contain magnesium salts are often used to treat occasional constipation. Osmotic laxatives relieve constipation by drawing water from tissues into the colon resulting in softer stools and the stimulation of intestinal motility, states MayoClinic.com.
Milk of Magnesia
Milk of Magnesia contains magnesium hydroxide and is classified as a saline osmotic laxative. According to Phillips' Milk of Magnesia product labeling, the usual dose for adults is 2 to 4 tablespoonfuls per day for occasional constipation. Each tablespoon contains 1200mg of magnesium hydroxide. The product further advises consumers to contact a physician if they require the use of laxatives for more than seven days. Milk of magnesia is also used as an effective antacid in the treatment of acid reflux.
Magnesium Citrate
Magnesium citrate is an oral solution that is primarily used as an osmotic laxative. Patients should take magnesium citrate according to the directions on the label or as instructed by a physician. Since magnesium citrate can be a potent laxative, adverse side effects include diarrhea and electrolyte imbalances, states the American Cancer Society.
Laxatives and Chronic Constipation
Since the use of laxatives can cause diarrhea and interfere with certain medications, patients should talk to a health care provider before using over-the-counter laxatives. Although laxatives may be an effective treatment for occasional episodes of constipation, prolonged use can affect intestinal contractions. As a result, frequent use of laxatives may lead to the development of chronic constipation.
