Antidiarrheals are medications used to treat diarrhoea, which is the frequent passage of loose or watery stools. Diarrhea can be caused by a variety of factors, such as food poisoning, viral or bacterial infections, certain medications, and other medical conditions. Antidiarrheals help to reduce the severity of symptoms, such as abdominal cramping, nausea, bloating, and urgency. The most common types of antidiarrheals are antimotility agents, which reduce the speed of the small intestine’s peristalsis. This allows more time for fluid and electrolytes to be absorbed, thus reducing the frequency of loose stools. Other common antidiarrheals are adsorbents, which help reduce the amount of toxins and bacteria in the intestines. These medications are usually taken orally and may come in the form of pills, capsules, liquids, or powders. Antidiarrheals are typically taken for a brief period of time until the underlying cause of the diarrhea has been identified and treated. If symptoms persist, a doctor should be consulted. Before taking antidiarrheals, it is important to know about potential side effects, such as constipation, dizziness, drowsiness, etc.
