Loperamide is a medicine that can help if you have acute diarrhoea. Acute diarrhoea in adults starts suddenly and in most cases eases within a few days. The main treatment is to have lots to drink to prevent dehydration. The most common cause of acute diarrhoea is an infection. Many bacteria, viruses, and other germs can cause diarrhoea. In most cases the diarrhoea settles as your body's immune system clears the infection. Antidiarrhoeal medicines like loperamide may not be necessary; however, they can be helpful if you wish to reduce the number of trips that you need to make to the toilet. Most people only need to take loperamide for a day or so.
