Data not available


Loperamide is considered contraindicated in patients with abdominal pain in the absence of diarrhea. Loperamide is not recommended as primary therapy in patients with acute dysentery characterized by blood in the stools and high fever, acute ulcerative colitis, bacterial enterocolitis caused by invasive organisms including Salmonella, Shigella, and Campylobacter, and in patients with pseudomembranous colitis associated with the use of broad-spectrum antibiotics. Loperamide is not recommended in infants less than 24 months of age.

Fluids and electrolytes should be replaced as necessary.

The use of loperamide is not recommended in patients in whom peristalsis is to be avoided due to the possible risk of significant sequelae (including ileus, megacolon, and toxic megacolon). Loperamide should be discontinued immediately in patients who develop constipation, abdominal distention, or ileus.

Whenever indicated and/or appropriate, the underlying etiology of the diarrhea should be determined and treated appropriately.

There are isolated reports of toxic megacolon in AIDS patients with infectious colitis (both viral and bacterial pathogens) treated with loperamide. Therefore, it is recommended to discontinue loperamide therapy in AIDS patients at the first sign of possible abdominal distention.

There are rare reports of allergic reactions including anaphylaxis and anaphylactic shock. Loperamide therapy should be stopped and a physician notified if symptoms get worse, diarrhea lasts for more than 48 hours, if blood is observed in the stools, or abdominal swelling or bulging occurs.

Caution is recommended in patients with hepatic dysfunction. In addition, these patients should be monitored closely for signs of central nervous system (CNS) toxicity.

Loperamide should be used with special caution in young children because of the greater variability of response in this age group. Dehydration, particularly in younger children, may further influence the variability of response to loperamide.

Loperamide may impair the mental abilities necessary for potentially hazardous tasks such as driving a car or operating machinery.

Other Comments

Maximum recommended dose for adults is 16 mg per day.

The duration of treatment for acute diarrhea generally does not exceed 48 hours.

Therapy should be accompanied by fluid and electrolyte replacement as needed.

Tolerance to the antidiarrheal effect of loperamide has not been reported.

Response and Effectiveness

Some effects may be seen within 20 minutes; however, takes about 2.5 hours (oral solution) or 5 hours (capsules) for loperamide to reach its peak effect.
