[Outline]
Imodium
- For achieving control and symptomatic relief of acute nonspecific diarrhea and chronic diarrhea associated with inflammatory bowel disease
- For reducing the volume of discharge from ileostomies
Imodium A-D, Imodium A-D EZ Chews, loperamide
- Indicated to control the symptoms of diarrhea, including traveler's diarrhea
See Supplemental Patient Information
- Administer appropriate fluid and electrolytes as fluid and electrolyte depletion often occur in patients who have diarrhea. The use of loperamide does not preclude the need for appropriate fluid and electrolyte therapy
- Do not use when inhibition of peristalsis is to be avoided due to the possible risk of significant sequelae including ileus, megacolon and toxic megacolon. Discontinue the drug immediately if constipation, abdominal distention or ileus develop
- Loperamide provides only symptomatic treatment of diarrhea; hence, appropriate treatment should be given for any underlying etiology
- Toxic megacolon has been reported in AIDS patients when treated with loperamide for infectious colitis; hence, use cautiously and stop the therapy at the earliest signs of abdominal distention
- Advise patients to discontinue therapy and consult their physician if there is no improvement in 48 hours
- Use cautiously in patients with hepatic impairment because of reduced first pass metabolism; and closely monitor such patients for signs of CNS toxicity
- Very rare cases of allergic reactions including anaphylaxis and anaphylactic shock have been reported during therapy
Cautions: Use cautiously in
- Pediatric patients
- High environmental temperature
- Advanced HIV disease
Supplemental Patient Information
- Advise patients to consult their physician if their diarrhea gets worse or lasts for more than 48 hrs or if they note blood or mucus in their stools and develop a fever or abdominal distention
- Caution patients against driving a car or operating machinery because loperamide may cause tiredness, dizziness, or drowsiness
- Advise patients to drink plenty of clear fluids in order to prevent dehydration associated with diarrhea
Pregnancy Category:C
Breastfeeding: Loperamide use during breastfeeding is unlikely to affect the infant. This information is based upon LactMed database (available at http://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?LACT last accessed 8 April 2011). As per manufacturer's data, loperamide is not recommended during breastfeeding.
