Indications

Loperamide + Simethicone is used to treat the symptoms of acute diarrhea in adults and adolescents over 12 years, when the diarrhea comes with gas-related discomfort in the abdomen such as bloating, cramping or flatulence.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Loperamide binds to the opiate receptor in the gut wall. This reduces propulsive peristalsis, so food and fluid move through the intestine more slowly, and more water and electrolytes are taken back into the body. Loperamide also increases the tone of the anal sphincter. Simethicone is a surface-active agent with anti-foaming properties, so it may relieve gas-related symptoms that come with diarrhea.

Most of the Loperamide that is swallowed is absorbed from the gut. But because of significant first pass metabolism, systemic bioavailability is approximately 0.3%. Simethicone is not absorbed.

Plasma protein binding of Loperamide is 95%. The liver extracts almost all of it, where it is mainly metabolized, conjugated and excreted through the bile. Loperamide has a half-life of about 11 hours. Unchanged Loperamide and its metabolites leave the body mainly in the faeces.

Pregnancy & Breastfeeding

Nobody has established that Loperamide with Simethicone is safe in human pregnancy. Animal studies show no signs of teratogenic or embryotoxic effects. Even so, it shouldn't be given during pregnancy, especially in the first trimester, unless there is a clinical reason for it.

Small amounts of Loperamide may pass into human breast milk. For that reason, this medicine is not recommended during breast feeding.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.

Dosage Reference

⚠️ Reference ranges from official sources only. Consult your doctor for personalized dosing.

Adults: For adults and children 12 years of age and older, the dose of Loperamide + Simethicone is 2 tablets after the first loose bowel movement, then one tablet or caplet after each loose bowel movement that follows. The maximum is 4 tablets or caplets a day, for no more than 2 days. Children 6 to 11 years of age: this medicine is not recommended for children under 12 years except on the advice of a physician. The proposed dose is 1 tablet after the first loose bowel movement and 1/2 tablet or caplet after each one after that. The daily maximum is 3 tablets or caplets for ages 9 to 11 years, or 2 tablets or caplets for ages 6 to 8 years, and it should not be used for longer than 2 days. Children under 12 years of age: the tablet should be used with special caution, because response varies more in children and swallowing may be difficult. Geriatrics (over 65 years of age): no dose adjustment is needed for the elderly. Renal impairment: no dosage adjustment is needed. Hepatic impairment: no pharmacokinetic data are available for patients with hepatic impairment. The tablet should still be used with caution in these patients because first pass metabolism is reduced. Administration: take the tablet by mouth. It can be taken at any time of day. Caplets should be taken with a full glass of water (250 mL). Chewable tablets should be chewed fully and then swallowed. Drink plenty of clear fluids, which helps prevent the dehydration that may come with diarrhea. Take it only on an empty stomach, which means 1 hour before or 2 hours after a meal.
