Stop eating and drinking immediately
If vomiting is likely from illness, dehydration, or food poisoning, rest
Take small sips of oral rehydration solution or water once vomiting slows
If you can keep fluids down, gradually return to light foods (e.g., crackers, toast, rice, bananas)
Avoid alcohol, greasy/spicy foods, and large meals
Rinse your mouth after vomiting and wait before brushing teeth
Stay upright or on your side to reduce choking risk
If vomiting continues, consider an OTC anti-nausea medication if appropriate for you
Contact a clinician if vomiting lasts more than 24 hours (adults) or 12 hours (children), or if it’s severe
Seek urgent care or emergency help if there is blood in vomit, black/coffee-ground vomit, severe belly pain, stiff neck, severe headache, chest pain, confusion, fainting, signs of dehydration (very little urination, dizziness, very dry mouth), high fever, or inability to keep even small sips down
For children: seek medical advice urgently if the child is under 6 months, very lethargic, has fewer wet diapers, sunken eyes, or persistent vomiting
If you suspect poisoning or ingestion of a harmful substance, call your local poison control or emergency services immediately
