4 Special warnings and special precautions for use). Method of administration Oral use. The capsules should be taken with liquid. 1. • in children less than 12 years of age. • in patients with acute dysentery, which is characterised by blood in stools and high fever.
• in patients with acute ulcerative colitis. • in patients with bacterial enterocolitis caused by invasive organisms including Salmonella, Shigella and Campylobacter. • in patients with pseudomembranous colitis associated with the use of broad- spectrum antibiotics.
Imodium must not be used when inhibition of peristalsis is to be avoided due to the possible risk of significant sequelae including ileus, megacolon and toxic megacolon. Imodium must be discontinued promptly when ileus, constipation or abdominal distension develop.
4 Special warnings and precautions for use Treatment of diarrhoea with Imodium is only symptomatic. Whenever an underlying etiology can be determined, specific treatment should be given when appropriate. The priority in acute diarrhoea is the prevention or reversal of fluid and electrolyte depletion.
This is particularly important in young children and in frail and elderly patients with acute diarrhoea. Use of this medicine does not preclude the administration of appropriate fluid and electrolyte replacement therapy. Since persistent diarrhoea can be an indicator of potentially more serious conditions, this medicine should not be used for prolonged periods until the underlying cause of the diarrhoea has been investigated.
In acute diarrhoea, if clinical improvement is not observed within 48 hours, the administration of Imodium should be discontinued and patients should be advised to consult their doctor. Patients with AIDS treated with this medicine for diarrhoea should have therapy stopped at the earliest signs of abdominal distension.
There have been isolated reports of obstipation with an increased risk for toxic megacolon in AIDS patients with infectious colitis from both viral and bacterial pathogens treated with loperamide hydrochloride. Although no pharmacokinetic data are available in patients with hepatic impairment, this medicine should be used with caution in such patients because of reduced first pass metabolism, as it may result in a relative overdose leading to CNS toxicity.
