Excipient with known effect: Pharmaceutical form Hard gelatin capsule — green and dark grey. For the symptomatic treatment of acute episodes of diarrhoea associated with Irritable Bowel Syndrome in adults aged 18 years and over following initial diagnosis by a doctor.
Adults and children over Two capsules 4 mg initially, followed by one capsule 2 mg after each loose stool. The usual dose is capsules 6 mg — 8 mg a day. The total daily dose should not exceed 6 capsules 12 mg. Symptomatic treatment of acute episodes of diarrhoea associated with irritable bowel syndrome in adults aged 18 and over Two capsules 4 mg to be taken initially, followed by 1 capsule 2 mg after every loose stool, or as previously advised by your doctor.
The maximum daily dose should not exceed 6 capsules 12 mg. Paediatric population Loperamide hydrochloride is contraindicated in children less than 12 years of age. Elderly No dose adjustment is required for the elderly. Renal Impairment No dose adjustment is required for patients with renal impairment. Hepatic Impairment Although no pharmacokinetic data are available in patients with hepatic impairment, loperamide hydrochloride should be used with caution in such patients because of reduced first pass metabolism see section 4.
Method of administration Oral use. The capsules should be taken with liquid. Loperamide hydrochloride must not be used when inhibition of peristalsis is to be avoided due to the possible risk of significant sequelae including ileus, megacolon and toxic megacolon.
Loperamide must be discontinued promptly when ileus, constipation or abdominal distension develop. Moderate The plasma concentration of loperamide, a P-glycoprotein P-gp substrate, may be increased when administered concurrently with nifedipine, a mild P-gp inhibitor. Major Loperamide should be avoided in combination with nilotinib. Nilotinib also prolongs the QT interval and the manufacturer advises against use with other drugs that prolong the QT interval.
If concurrent administration is unavoidable, the manufacturer of nilotinib recommends interruption of nilotinib treatment. If nilotinib must be continued, closely monitor the patient for QT interval prolongation. In addition, if these drugs are used together, the plasma concentrations of loperamide may increase. Nilotinib is an inhibitor of all 4 enzymes and P-gp, further increasing the risk of toxicity.
Monitor for cardiac toxicities i. Moderate Loperamide should be used cautiously and with close monitoring with norfloxacin. Quinolones have been associated with a risk of QT prolongation and TdP. Although extremely rare, torsade de pointes has been reported during post-marketing surveillance of norfloxacin.
These reports generally involved patients with concurrent medical conditions or concomitant medications that may have been contributory. Moderate Loperamide should be used cautiously and with close monitoring with octreotide. Arrhythmias, sinus bradycardia, and conduction disturbances have occurred during octreotide therapy.

The authors concluded that there may be moderate risks in infants exposed to loperamide in early pregnancy. There are no adequate and well-controlled studies in pregnant women. Loperamide should be used with caution during pregnancy and only when the potential maternal benefit outweighs any potential fetal risk.
As with all medications, women should consult their health care professional prior to self-treatment during pregnancy. While manufacturers do not recommend loperamide use during lactation ; the American Academy of Pediatrics generally considers the use of loperamide compatible with breast-feeding as use during lactation is unlikely to adversely affect the infant.
Small amounts of loperamide may appear in human breast milk, based on data of the excretion of loperamide in human breast milk at low levels following use of a prodrug, loperamide oxide. As with all medications, women should consult their health care professional prior to self-treatment during lactation.
Loperamide interferes with peristalsis by a direct action on the circular and longitudinal muscles of the intestinal wall to slow motility. By increasing the transit time of the intestinal contents, loperamide reduces fecal volume, increases the bulk density and the viscosity of the feces, and decreases the loss of electrolytes and fluids from the body.
