Imodium

Loperamide, the active ingredient in Imodium, is an antidiarrheal (peripheral opioid receptor agonist) presented as an oral dosage form for oral use. It treats acute nonspecific diarrhea, chronic diarrhea associated with inflammatory bowel disease, and irritable bowel syndrome with diarrhea in adults.

GNH USA supplies Imodium as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Imodium is an antidiarrheal that acts on peripheral µ‑opioid receptors to reduce intestinal motility. It is indicated for: - Acute nonspecific diarrhea: decreases stool frequency and improves consistency. - Chronic diarrhea associated with inflammatory bowel disease: helps control bowel movements and reduces urgency. - Irritable bowel syndrome with diarrhea (IBS‑D): alleviates diarrheal episodes and abdominal discomfort.

Common Side Effects: - Constipation: reduced bowel movements may become hard or infrequent. - Nausea: mild stomach upset may occur. - Abdominal cramps: occasional discomfort or cramping. - Dizziness: transient light‑headedness. - Dry mouth: reduced salivation. - Headache: mild to moderate pain.

Serious or Rare Side Effects: - Severe constipation or bowel obstruction: risk of impaction. - Toxic megacolon: rare but life‑threatening colonic dilation. - Allergic reactions: rash, itching, or swelling. - Cardiac arrhythmia: QT prolongation with high plasma levels. - Ileus: paralytic intestinal obstruction. - Urinary retention: difficulty voiding.

Before using Imodium, consider the following precautions: - Assess hydration status: ensure adequate fluid replacement. - Avoid use in children under 2 years: risk of serious side effects. - Do not exceed recommended duration: prolonged use may mask underlying disease. - Use with caution in hepatic impairment: metabolism may be reduced. - Store at room temperature: keep in the original pack, protect from moisture.

Imodium may interact with several medicines. Monitor the following: Major Interactions (Avoid): - CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): can raise loperamide levels and increase cardiac risk. - Concomitant antidiarrheals (e.g., diphenoxylate): may cause severe constipation. Moderate Interactions (Monitor Closely): - CYP3A4 inducers (e.g., rifampicin): may reduce efficacy. - Opioid analgesics: additive central nervous system effects. - Anticholinergic agents: may exacerbate constipation.
