All you have to do is manage symptoms, especially diarrhea, and avoid complications until the illness passes. In most cases, dehydration caused by diarrhea is the main complication.
Extra precautions should be taken to prevent dehydration in children.
The goal of treatment is to replace fluids and electrolytes lost through vomiting and diarrhea. If dehydration is severe and can't be managed at home, you may need treatment in the hospital, where fluids and electrolytes may be given to you by inserting a needle into your vein (intravenously).
Medicines that stop diarrhea (such as Imodium) can help with your symptoms. But these medicines shouldn't be used in children or in people with a high fever or bloody diarrhea. Antibiotics are rarely used and only for certain types of food poisoning or in severe cases. Pregnant women with listeriosis or toxoplasmosis may receive antibiotics.
