The symptoms of food poisoning resolve for most patients within a few days without treatment, according to Mayo Clinic. In severe cases, common treatments include administering fluids intravenously to prevent dehydration or prescribing antibiotics if the patient is dealing with certain types of bacterial food poisoning.
Pepto-Bismol or Imodium A-D often provide relief for adult patients dealing with non-bloody diarrhea without a fever, reports Mayo Clinic. Patients who choose to treat mild food poisoning at home can prevent dehydration by sucking on ice chips and drinking small amounts of clear liquids when possible. After the stomach settles, it is best to begin eating again by choosing bland foods, such as crackers, toast, bananas and rice.
