This medication is available without a prescription. If you are taking this medication for self-treatment, it is important to read the manufacturer's package instructions carefully so you know when to consult your doctor or pharmacist.

Healthy bowel movements can range from three movements a day to three a week. Stools generally should be passed without excess effort, straining or discomfort. Constipation is the infrequent and/or difficult passage of stool. Because the function of the large intestine or colon is to absorb water, delayed movement through the colon leads to constipation with hardening of the stools and infrequent bowel movements. You should avoid alcohol and caffeinated beverages such as coffee, tea, and cola drinks. These are diuretics, which eliminate water from your body and contribute to dehydration.

If more than three days pass without a bowel movement, the intestinal contents may harden to the point that the person may have difficulty during elimination. The feeling of incomplete evacuation or straining may also be reported as constipation.

Common causes of constipation include:

• Inadequate water intake
• Inadequate fiber in the diet
• A disruption of regular diet or routine; traveling
• Inadequate activity or exercise or immobility
• Eating large amounts of dairy products
• Stress
• Depression
• Eating disorders
• Irritable bowel syndrome
• Pregnancy

Lack of good nerve and muscle function in the bowel may also be a cause of constipation.

  • Eat at regularly scheduled times and try to eat regular meals. Missing meals or eating on the run may affect your digestive system.
  • Watch your diet and the foods you eat. Keep track of what you eat and the types of food that are missing from your diet. Diet and food choices are associated with constipation, so a healthy diet makes sense.
  • Drink lots of fluids, especially water. Drink sufficient amounts of water or other decaffeinated liquids a day. Consult your physician about recommended fluid intake if you are on a fluid-restricted diet. Avoid consuming caffeinated or alcoholic beverages.
  • Know your body’s signals and when you need to go, and try to have a regular time for your bowel movement. This will help make it part of your routine and you won’t feel rushed.
  • Keep track of your daily exercise routine as well as how often and what type of activity you do weekly.
