2mg caplets — fast-acting anti-diarrheal
Order FDA-Approved Loperamide 2mg — Fast Diarrhea Control, Same as Imodium A-D
2mg caplets, 24-count pack
Loperamide HCl 2mg is an OTC anti-diarrheal medication used to control and relieve symptoms of acute diarrhea, including traveler's diarrhea. It is the active ingredient in Imodium A-D. Loperamide slows intestinal movement and decreases stool frequency, allowing the body to reabsorb water and electrolytes more effectively. It is one of the most effective and widely used OTC anti-diarrheal agents available.
Loperamide 2mg is indicated for the relief of acute diarrhea (including traveler's diarrhea), control of chronic diarrhea associated with inflammatory bowel disease (under medical supervision), and reduction of the volume of discharge from ileostomies. It is approved for OTC use and does not require a prescription for standard adult doses.
Loperamide acts on opioid receptors in the gut wall (mu-opioid receptors) to slow intestinal peristalsis — the rhythmic contractions that move stool through the intestines. By slowing gut motility, it allows more time for water and electrolytes to be reabsorbed from the stool, resulting in firmer stools and reduced frequency of bowel movements. It also reduces intestinal secretions. It acts locally in the gut and does not enter the bloodstream significantly at therapeutic doses.
Adults and children 12 and over: Take 2 caplets (4mg) after the first loose stool. Then 1 caplet (2mg) after each subsequent loose stool. Do not exceed 8mg (4 caplets) in 24 hours for self-treatment. Drink plenty of fluids to prevent dehydration. Do not use for more than 2 days without medical advice. Discontinue if diarrhea does not improve within 48 hours.
Loperamide 2mg OTC is for adults and children 12 and older. Do not use for diarrhea with fever or if stool contains blood. Not for children under 12 unless directed by a doctor. Avoid in patients with acute dysentery or bacterial enterocolitis. Consult a doctor if diarrhea is accompanied by high fever or if you have inflammatory bowel disease.
Loperamide is generally safe at OTC doses. Possible side effects include constipation, stomach cramping, bloating, nausea, and dizziness. Serious side effects are extremely rare at recommended doses. Do not exceed the labeled dose — overdose at very high doses can cause serious heart rhythm problems. Stop use if symptoms worsen or if fever or blood in stool develops.

Loperamide 2mg typically starts working within 1 hour of the first dose, with significant improvement within 2–4 hours. It works by slowing intestinal motility and reducing the frequency of bowel movements. Source: MedlinePlus: Loperamide.
Adults: Take 2 tablets (4mg) as an initial dose, then 1 tablet (2mg) after each loose stool. Do not exceed 8mg (4 tablets) in 24 hours for OTC use. If diarrhea does not improve after 2 days, consult a doctor. Children under 12: consult a doctor before use.
Loperamide is FDA-approved and safe when used as directed for acute diarrhea. The FDA warns against exceeding recommended doses — extremely high doses can cause dangerous heart rhythm problems. Always use as directed.
Do not use loperamide if you have blood in stool, black/tarry stools, or fever — these may indicate a bacterial infection requiring antibiotics rather than stool-hardening. Also avoid if you have Clostridioides difficile infection. Consult a doctor if diarrhea is accompanied by fever over 101°F.
Loperamide physically slows intestinal movement to reduce stool frequency. Bismuth subsalicylate (Pepto-Bismol) has anti-inflammatory and antibacterial properties. For travel diarrhea, loperamide is faster and stronger; Pepto-Bismol is better for nausea, indigestion, and mild stomach upset.
