The most effective remedies for vomiting depend on what’s causing it, but the immediate priorities are always the same: stop the stomach irritation, replace lost fluids, and ease back into eating. For most cases of acute vomiting from a stomach bug or food that didn’t agree with you, a combination of small sips of clear fluids, rest, and a temporary break from solid food will resolve things within 12 to 24 hours.
Start With Small Sips, Not Big Gulps
The single most important thing you can do after vomiting is prevent dehydration. Your body loses water, sodium, and potassium every time you throw up, and replacing those is more urgent than eating. But drinking a full glass of water right away can trigger another round of vomiting. Instead, take small sips every few minutes and gradually increase the amount as your stomach settles.
Good options include water (plain, carbonated, or flavored), sports drinks, clear broth, apple or white grape juice, gelatin, ice pops, and weak tea. Coffee is fine if it’s black, but milk or cream can irritate an already sensitive stomach. Flat ginger ale or cola are traditional choices, though the sugar content can sometimes make nausea worse. If plain water is all you can manage, that’s enough to start.
For children, the approach is similar but the stakes are higher because they dehydrate faster. Offer a teaspoon or tablespoon of fluid at a time, every five to ten minutes. Oral rehydration solutions designed for kids are ideal because they contain the right balance of sugar and electrolytes. Signs of dehydration to watch for in children include fewer wet diapers, no tears when crying, and a dry mouth.
Over-the-Counter Medications That Help
Several drugstore medications can reduce nausea and vomiting. The most widely available are antihistamines, which work by blocking signals in the brain that trigger the vomit reflex. Dimenhydrinate (sold as Dramamine) and meclizine (sold as Bonine or Dramamine-N) are particularly effective for motion sickness and vertigo-related nausea. Diphenhydramine (Benadryl) also has anti-nausea properties, though drowsiness is a common side effect with all of these.
Bismuth subsalicylate (Pepto-Bismol) is another option that coats the stomach lining and can calm nausea from food-related illness. It won’t stop vomiting caused by motion sickness or inner-ear problems, but it’s useful for the garden-variety stomach upset.
Ginger and Acupressure: What Actually Works
Ginger has genuine anti-nausea effects. It speeds up stomach emptying and contains compounds that block some of the same receptors that prescription anti-nausea drugs target. Ginger tea, ginger chews, or even flat ginger ale made with real ginger can help take the edge off. Capsules containing dried ginger root are another option if the taste doesn’t appeal to you.
Pressing on a specific point on your inner wrist, known as the P6 or Neiguan point, also has real evidence behind it. It’s located about three finger-widths below the base of your palm, between the two tendons on the inside of your forearm. A Cochrane review pooling data from more than 3,000 patients found that P6 stimulation was superior to a placebo for both nausea and vomiting after surgery. For nausea specifically, pooled data showed P6 stimulation performed as well as or better than anti-nausea medication. You can press the point firmly with your thumb for a few minutes, or use an acupressure wristband (often marketed for motion sickness) that applies constant pressure.
When and What to Eat Again
Don’t rush back to food. Wait until you’ve gone at least a few hours without vomiting before trying anything solid. When you do start eating, keep portions small and stick to bland, low-fat options. The classic BRAT diet (bananas, rice, applesauce, toast) is a fine starting point, but you don’t need to limit yourself to just those four foods.
Other well-tolerated options include plain crackers, potatoes, broth-based soup, gelatin, cooked vegetables, eggs, refined-flour pasta, hot cereal like Cream of Wheat, lean poultry that’s baked or steamed, and creamy peanut butter on white toast. Popsicles and custard are also easy on the stomach while providing some calories. The goal is to avoid anything greasy, spicy, heavily seasoned, or high in fiber for the first day or two. Dairy should be low-fat or fat-free if you include it at all. Citrus juices and tomato-based foods can irritate the stomach lining, so hold off on those until you’re feeling solidly better.
Pregnancy-Related Nausea
Morning sickness responds to a different set of tools. The first-line treatment recommended by medical guidelines is a combination of vitamin B6 and doxylamine, an antihistamine found in some over-the-counter sleep aids. This combination is the only FDA-approved treatment specifically for nausea and vomiting during pregnancy. The typical approach starts with two tablets at bedtime, then adds a morning dose if symptoms persist into the next afternoon.
Eating small, frequent meals throughout the day, keeping crackers by the bed to eat before standing up in the morning, and avoiding strong smells can all reduce the frequency of episodes. Ginger is also considered safe during pregnancy and can provide mild relief. Acupressure wristbands are worth trying, though study results for pregnancy-related nausea have been mixed compared to the stronger evidence for post-surgical nausea.
Preventing the Spread
If a stomach virus is behind the vomiting, the pathogen (most commonly norovirus) is extremely contagious and can survive on household surfaces for days. Clean any contaminated surfaces with a disinfectant specifically registered to kill norovirus. The EPA maintains a list of approved products, and you can verify yours by checking for an EPA registration number on the label. Bleach-based cleaners and products containing hydrogen peroxide are among the most effective, with contact times as short as one to five minutes. Quaternary ammonium disinfectants (found in many spray cleaners) also work but need to stay wet on the surface for about ten minutes. Wash contaminated clothing and linens in hot water and dry on the highest heat setting.
Signs That Need Medical Attention
Most vomiting runs its course without complications, but certain warning signs mean you should get to urgent care or an emergency room. Vomit that contains blood, looks like coffee grounds, or is bright green indicates something more serious than a stomach bug. Fecal odor in vomit is a medical emergency that suggests a bowel obstruction.
Dehydration is the other major concern. If you notice excessive thirst, dark urine, very infrequent urination, dizziness when standing, or significant weakness, you likely need intravenous fluids. In children, these signs develop faster, and any child who can’t keep small sips of fluid down for more than a few hours should be evaluated. Vomiting that lasts more than 24 hours in adults, or that follows a head injury, also warrants prompt evaluation.
