Diarrhoea Relief - Loperamide Capsules helps to relieve the symptoms of acute diarrhoea, so you can get on with your life without any disruptions. Diarrhoea Relief - Loperamide Capsules contain the active ingredient, Loperamide, that works to slow the muscular contractions of the intestine, to help relieve diarrhoea. How does Loperamide work? Loperamide reduces the speed at which the gut contents are pushed through the intestines, allowing more time for water and electrolytes to be reabsorbed from the gut contents back into the body. It results in firmer stools that are passed less frequently. Approved by Claire Makey - Pharmacist on the 27/04/2021. For more information, view our medical team
