Medical Therapy

Treatment consists mainly of replacing fluids and salts lost because of diarrhea. Oral replacement is satisfactory for most people, but some may need to receive fluids intravenously. In most cases, the disease resolves within 4 to 8 days without antibiotics. Severe infections may last 3 to 6 weeks. Antibiotics such as trimethoprim-sulfamethoxazole, norfloxacin, ciprofloxacin, or furazolidone may be given when the person is very young or very old, when the disease is severe, or when there is a high risk of the infection spreading to other people. The severity of the symptoms and the length of time the stool contains Shigella are reduced with antibiotics. Antidiarrheal drugs (such as diphenoxylate or loperamide) may prolong the infection and should not be used.
