Diasis Syrup is used to treat bacterial and protozoal infections, including giardiasis, amebiasis, and enteritis in children. Additionally, it helps manage infectious diarrhoea caused by bacteria or protozoa. It contains furazolidone and metronidazole, which kill the bacteria and microorganisms that cause infections. In some cases, this medicine may cause side effects such as fever, nausea, headache, a metallic taste, and discolouration of urine. Inform the doctor if your child is taking any other medication or has any pre-existing medical conditions.
