Common use

Imodium is commonly used to manage symptoms of acute, non-specific diarrhea in adults and children above a specified age. It is also frequently utilized by travelers to prevent or treat diarrhea associated with changes in diet or water quality. Additionally, it can offer symptomatic relief for patients with chronic conditions such as irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD), though consultation with a healthcare provider is advised for long-term use.

Dosage and direction

For adults and children 12 years and older, the initial dose is two caplets (4 mg) after the first loose stool, followed by one caplet (2 mg) after each subsequent loose stool. Do not exceed 8 mg in 24 hours. For children aged 6–11, use only under medical supervision with age-appropriate formulations. Always take with water unless otherwise directed, and do not use for more than two days unless advised by a physician.

Precautions

Do not use if you have a fever or if there is blood or mucus in your stool. Avoid use in cases of acute dysentery, which may be worsened by antimotility agents. Use with caution in patients with hepatic impairment, as metabolism may be affected. Discontinue use if abdominal distention occurs. Pregnant or breastfeeding individuals should consult a healthcare provider before use.

Contraindications

Imodium is contraindicated in patients with a known hypersensitivity to loperamide or any component of the formulation. It should not be used in children under 6 years of age. Avoid in patients with abdominal pain without diarrhea, acute ulcerative colitis, pseudomembranous colitis associated with antibiotic use, or bacterial enterocolitis caused by invasive organisms.

Possible side effects

Common side effects may include constipation, dizziness, drowsiness, or nausea. In rare cases, allergic reactions such as skin rash, itching, or swelling may occur. Serious side effects like severe abdominal pain, bloating, or symptoms of toxic megacolon are uncommon but require immediate medical attention if experienced.

Drug interaction

Loperamide may interact with certain medications, including P-glycoprotein inhibitors (e.g., quinidine, ritonavir) and CYP3A4 inhibitors (e.g., ketoconazole, erythromycin), potentially increasing loperamide plasma concentrations. Concurrent use with other central nervous system depressants may enhance drowsiness or dizziness. Always inform your healthcare provider of all medications you are taking.

Missed dose

As Imodium is taken as needed for diarrhea symptoms, a missed dose is not applicable. Do not double the dose; simply take the next dose after the next loose stool, adhering to the maximum daily limit.

Overdose

Overdose may result in symptoms such as constipation, central nervous system depression, or respiratory depression. In case of suspected overdose, seek immediate medical attention or contact a poison control center. Treatment is supportive and may include activated charcoal if ingestion was recent.

Storage

Store at room temperature (20–25°C or 68–77°F), away from moisture, light, and heat. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
