Imodium (loperamide hydrochloride) is an over-the-counter antidiarrheal medication designed to provide rapid and effective relief from acute diarrhea. As an opioid receptor agonist, it works by slowing intestinal motility, allowing for increased water absorption and more formed stools. Trusted by healthcare professionals and consumers alike, Imodium offers a clinically proven solution to restore normal digestive function, reduce discomfort, and help individuals resume daily activities with confidence. Its targeted mechanism ensures symptomatic relief without central nervous system depression when used as directed.

Common use

Imodium is indicated for the control and symptomatic relief of acute, non-specific diarrhea. It is commonly used in cases of traveler’s diarrhea, viral gastroenteritis, or dietary indiscretion. The medication is suitable for adults and children ages 6 and above, providing a reliable option for managing temporary gastrointestinal disturbances. It is not intended for chronic diarrheal conditions unless directed by a physician.

Dosage and direction

For adults and children 12 years and older: Take two caplets (4 mg) initially, followed by one caplet (2 mg) after each loose stool. Do not exceed 8 mg in 24 hours.
For children ages 6–11: Administer one caplet (2 mg) initially, then one caplet after each subsequent loose stool. Maximum daily dose should not exceed 6 mg. Always use the measuring device provided for liquid formulations. Take with water if needed; may be taken with or without food. Discontinue use if diarrhea persists beyond 48 hours.

Precautions

Do not use if you have a fever or if stools are bloody. Avoid in cases of known hypersensitivity to loperamide or any component of the formulation. Use with caution in patients with hepatic impairment, as metabolism may be affected. Elderly patients may be more susceptible to side effects and should use the lowest effective dose. Not recommended during pregnancy or breastfeeding unless advised by a healthcare provider.

Contraindications

Imodium is contraindicated in patients with abdominal pain without diarrhea, acute dysentery (characterized by blood in stools and high fever), pseudomembranous colitis associated with antibiotic use, or known obstructive bowel disorders. Do not administer to children under 6 years of age.

Possible side effects

Common side effects may include constipation, dizziness, drowsiness, or nausea. Rare but serious side effects can include allergic reactions (rash, itching, swelling), severe abdominal distention, or paralytic ileus. Discontinue use and seek medical attention if tachycardia, urinary retention, or significant central nervous system effects such as stupor occur.

Drug interaction

Loperamide may interact with P-glycoprotein inhibitors (e.g., quinidine, ritonavir) and CYP3A4 inhibitors (e.g., ketoconazole, erythromycin), potentially increasing systemic absorption and risk of adverse effects. Concurrent use with other central nervous system depressants may enhance sedative effects. Consult a healthcare provider before use if taking prescription medications.

Missed dose

Imodium is taken as needed based on bowel movements rather than on a fixed schedule. If a dose is missed after a loose stool, take it as soon as remembered unless it is nearly time for the next loose stool. Do not double the dose.

Overdose

Overdose may manifest as central nervous system depression, including drowsiness, lethargy, or uncoordinated movements. In severe cases, respiratory depression or paralytic ileus may occur. Seek immediate medical attention. Naloxone may be used in cases of respiratory depression, though response may be incomplete due to loperamide’s peripheral action.

Storage

Store at room temperature (20–25°C), away from moisture, light, and heat. Keep packaging intact until use. Do not use if blister seals are broken or packaging is compromised. Keep out of reach of children and pets.
