There is no specific medicine to treat people with norovirus illness.
If you have norovirus illness, you should drink plenty of liquids to replace fluid lost from vomiting and diarrhea. This will help prevent dehydration.
Dehydration can lead to serious problems. Severe dehydration may require hospitalization for treatment with fluids given through your vein (intravenous or IV fluids).
Watch for signs of dehydration in children who have norovirus illness. Children who are dehydrated may cry with few or no tears and be unusually sleepy or fussy.
If you think you or someone you are caring for is severely dehydrated, call the doctor.
Antibiotic drugs will not help because they fight bacteria, not viruses.
