If you’re throwing up, the most important first steps are to stop eating, take small sips of water, and let your stomach rest. What you take next depends on the cause: over-the-counter options like bismuth subsalicylate (Pepto-Bismol) work well for stomach bugs, antihistamines like dimenhydrinate (Dramamine) are best for motion sickness, and ginger can help with mild nausea from various causes. Staying hydrated matters more than any medication.
Let Your Stomach Rest First
Right after vomiting, skip food and drinks for a couple of hours. Your stomach needs a short break before you put anything back in. Once that window passes, start with ice chips or tiny sips of water every 15 minutes. This tests whether your stomach can hold anything down without triggering another round.
Once water stays down, move to other clear fluids: clear broth, watered-down electrolyte drinks, ice pops, or gelatin. When you’ve kept liquids down for a few hours, try small amounts of bland food like plain toast, crackers, bananas, applesauce, or plain oatmeal. You don’t need to limit yourself strictly to those foods. Brothy soups, boiled potatoes, and unsweetened dry cereal are also gentle enough for a recovering stomach.
As you feel better, add more nutritious options: cooked carrots, sweet potatoes without skin, avocado, skinless chicken or turkey, fish, and eggs. Most people can return to normal eating within a day or two.
Over-the-Counter Medications That Help
The right OTC medication depends on why you’re vomiting.
Bismuth subsalicylate (Pepto-Bismol, Kaopectate) works by coating and protecting your stomach lining. It’s your best bet for nausea and vomiting caused by stomach flu, food poisoning, or general stomach upset. It also helps with diarrhea, which often accompanies these conditions.
Antihistamines like dimenhydrinate (Dramamine) and meclizine (Dramamine Less Drowsy) are designed for motion sickness. They work by dulling your inner ear’s ability to sense motion and blocking the signals that tell your brain to trigger nausea. The key with these is timing: they work best when you take them before you start feeling sick, not after vomiting has already started. If you know you’re prone to carsickness or seasickness, take a dose before your trip.
When You Need a Prescription
For vomiting that doesn’t respond to OTC options, doctors often prescribe ondansetron (Zofran). It works by blocking serotonin, a chemical your body releases that can trigger nausea and vomiting. Ondansetron was originally developed for chemotherapy patients but is now widely used for severe stomach bugs and other causes of persistent vomiting. It comes in tablets, liquid, and a dissolving film you place on your tongue, which is helpful when you can’t keep a pill down.
For children six months and older with vomiting from a stomach bug, a single oral dose of ondansetron is sometimes given in emergency departments to stop the cycle so the child can start drinking fluids again. Rehydration typically begins 15 to 30 minutes after the dose. A single dose is standard for kids because multiple doses haven’t shown additional benefit, and diarrhea is a common side effect.
Ginger as a Natural Option
Ginger is one of the few natural remedies with real clinical evidence behind it. Studies have tested daily doses of 975 to 1,500 mg, divided into three or four portions throughout the day. That’s roughly equivalent to a few cups of strong ginger tea or ginger capsules from a health food store. Fresh ginger sliced into hot water, ginger chews, or ginger ale made with real ginger (check the label, most commercial brands use flavoring only) are practical ways to get it in when your stomach is unsettled.
Ginger tends to work best for mild to moderate nausea. It’s well studied in pregnancy-related nausea and morning sickness specifically, but many people find it helpful for general stomach upset as well.
Hydration Is the Priority
Vomiting drains your body of water, sodium, potassium, and other electrolytes faster than most people realize. Plain water helps, but it doesn’t replace what you’ve lost. Oral rehydration solutions like Pedialyte contain a specific balance of sodium, potassium, and glucose designed to maximize absorption. The World Health Organization’s formula uses 75 mmol/L each of sodium and glucose plus 20 mmol/L of potassium, a ratio that pulls water into your system more efficiently than water alone.
Sports drinks like Gatorade or Powerade aren’t ideal replacements. They contain too much sugar and not enough sodium compared to proper rehydration solutions. If an oral rehydration solution isn’t available, diluting fruit juice half and half with water or sipping clear broth are reasonable alternatives. Weak decaffeinated tea also works.
Signs of Dehydration to Watch For
In adults, the early signs of dehydration include extreme thirst, dark-colored urine, urinating less than usual, tiredness, and dizziness. As it progresses, you may notice confusion, sunken eyes, or skin that stays pinched up instead of flattening back immediately when you pull it. In infants and young children, warning signs include no wet diapers for three hours, no tears when crying, a sunken soft spot on the head, and unusual irritability or sleepiness.
Seek medical attention if vomiting has lasted 24 hours or more, if you can’t keep any fluids down, if you notice blood or black color in your vomit or stool, or if you develop a fever of 102°F or higher. Confusion and excessive sleepiness in anyone, especially children, are also red flags that dehydration has become serious.
What to Avoid While Recovering
Dairy products, greasy or fried foods, spicy dishes, and acidic foods like tomato sauce and citrus are all harder for an irritated stomach to handle. Caffeine and alcohol are also poor choices since both can worsen dehydration and irritate your stomach lining. Carbonated drinks may feel soothing but can increase bloating and discomfort for some people.
Eating large meals too quickly is a common mistake during recovery. Even once you feel hungry again, small portions every couple of hours are easier on your system than a full plate. Your stomach needs a gradual ramp-up, not a sudden return to normal volume.
