Necrotizing enterocolitis with perforation was reported in two women following short courses (24 hours and 3 days) of loperamide (the active ingredient contained in Kaopectate 1-D) for the treatment of acute diarrhea with fever. Resected bowel in both cases revealed extensive mucosal hemorrhage and necrosis.
Toxic megacolon has been reported in association with the use of loperamide to treat symptoms of ulcerative colitis and pseudomembranous colitis due to antibiotic therapy. In one patient treated for ulcerative colitis, abdominal symptoms seemed to improve in the days before requiring emergency laparotomy.
Loperamide has also been implicated in a case of appendicitis. A 35-year-old male self-treated traveler's diarrhea with loperamide at greater than the recommended daily dose for seven days. Three days later, an appendalith was noted during an emergency appendectomy. The authors speculated that fecal stasis induced by loperamide increases the risk of fecalith and appendalith formation, the latter being associated with the pathogenesis of appendicitis.
Gastrointestinal side effects reported during loperamide therapy are often likely due to the underlying illness and include nausea, vomiting, dyspepsia, abdominal cramps, and anorexia.
Cases of paralytic ileus associated with abdominal distention have been reported rarely. Many of these reports had occurred in a setting with acute dysentery, overdose, and children less than 2-years-old.

In opioid addicted monkeys, loperamide in high doses did prevent withdrawal symptoms.
A 26-year-old male with a history of opioid and alcohol abuse, began taking loperamide for the treatment of acute diarrhea. Despite denying euphoric effects from the drug, he gradually increased his intake to 320 mg per day.
