Iodoquinol is a medication primarily used to treat infections caused by certain parasites, particularly Entamoeba histolytica, which can lead to amoebic dysentery. It works by inhibiting the growth of these parasites in the intestines, helping to alleviate symptoms and clear the infection. This drug is usually taken orally and is often prescribed when other treatments are not effective. While generally well-tolerated, some people may experience side effects such as nausea or skin rashes. It's important to follow a healthcare provider's instructions when using iodoquinol to ensure safe and effective treatment.
