The most effective immediate strategy when you’re throwing up is to stop eating, take small sips of clear fluids, and let your stomach rest. Most vomiting from common causes like stomach bugs, food poisoning, or motion sickness resolves within 24 to 48 hours with simple home care. The key is preventing dehydration while your body recovers, then gradually reintroducing food.
What to Do Right After Vomiting
Wait at least 15 to 30 minutes after your last episode before drinking anything. Then start with small sips of water, just a tablespoon or two at a time. If that stays down, slowly increase the amount over the next hour or two. Gulping a full glass of water on an empty, irritated stomach often triggers another round of vomiting.
Good options during this phase include water, clear broth, plain gelatin, ice pops (without milk or fruit bits), and ice chips. Peppermint or lemon hard candies can also help settle nausea between episodes. Avoid milk, juice with pulp, coffee, and alcohol, all of which can irritate your stomach further.
Stay upright or prop yourself up at a slight angle rather than lying flat. Fresh air helps too. If you can, sit near an open window or step outside briefly. Deep, slow breaths through the nose can calm the nausea reflex.
Staying Hydrated Is the Priority
Dehydration is the biggest real risk from repeated vomiting. You lose water, sodium, and potassium every time you throw up, and replacing those electrolytes matters more than eating. Oral rehydration solutions (sold as Pedialyte, DripDrop, or store-brand equivalents) are specifically designed for this. The World Health Organization’s formula balances sodium and glucose at concentrations that maximize absorption through the intestinal wall, which plain water can’t do as efficiently.
If you don’t have a rehydration solution on hand, alternate between sips of water and sips of clear broth, which provides sodium. Sports drinks are a second-tier option since they contain more sugar than ideal, but they’re better than nothing. The goal is frequent, tiny amounts rather than large drinks spaced far apart. Think a sip every five minutes rather than a cup every hour.
Ginger Actually Works
Ginger is one of the few natural remedies with solid clinical evidence behind it. Its active compounds block serotonin receptors in the gut that trigger the vomiting reflex, essentially interfering with the chemical signal your body uses to initiate nausea. A systematic review of clinical trials found that ginger supplementation of up to 1 gram per day reduced vomiting episodes by 70% compared to a placebo when taken for more than four days.
For immediate relief, ginger tea, ginger chews, or flat ginger ale (with real ginger, not just flavoring) are practical options. Capsules containing powdered ginger root are available at most pharmacies. Fresh ginger steeped in hot water for 10 minutes makes a simple tea. Even just smelling fresh-cut ginger can ease mild nausea for some people.
Pressure Point on Your Wrist
A technique called P6 acupressure involves pressing a spot on the inside of your wrist, about three finger-widths below your palm, between the two tendons. In a controlled trial of 90 patients with persistent nausea, those who received P6 acupressure had significantly lower nausea severity and vomiting frequency at two, four, and six hours compared to both placebo and control groups. The acupressure group also needed fewer anti-nausea medications over 24 hours.
You can apply firm pressure with your thumb for two to three minutes at a time, or wear “sea bands,” which are elastic wristbands with a plastic nub that presses the spot continuously. It’s free, has no side effects, and you can do it anywhere.
When to Start Eating Again
Return to solid food as soon as you can tolerate it. The old advice to stick strictly to the BRAT diet (bananas, rice, applesauce, toast) for days isn’t well supported. Harvard Health notes there are no studies comparing BRAT to other approaches, and restricting yourself to just those four foods deprives your body of the protein and nutrients it needs to recover.
A better approach: start with bland, easy-to-digest foods and expand from there. Good first meals include brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereal. Once those sit well, add cooked squash, carrots, sweet potatoes without skin, avocado, skinless chicken or turkey, fish, and eggs. These foods are gentle on the stomach but deliver the protein and micronutrients your body needs after being depleted.
Avoid greasy, spicy, or heavily seasoned food for a day or two. Eat small portions rather than full meals. If a food triggers nausea again, back off and try something milder.
Over-the-Counter Medications
Bismuth subsalicylate (the active ingredient in Pepto-Bismol) coats the stomach lining and can reduce nausea from mild stomach bugs or food irritation. Dimenhydrinate (Dramamine) and meclizine work well for motion sickness and vertigo-related vomiting by calming the inner-ear signals that trigger nausea.
For more persistent vomiting, prochlorperazine is available over the counter in the United States. It works by blocking dopamine receptors involved in the vomiting reflex and is more targeted than general antihistamines. If you’re vomiting so frequently that you can’t keep a pill down, some of these medications come in suppository or dissolving tablet forms.
Warning Signs That Need Medical Attention
Most vomiting resolves on its own, but certain symptoms signal something more serious. Get to an emergency room if your vomit contains blood, looks like coffee grounds, or is bright green. The same applies if vomiting comes with chest pain, severe abdominal cramping, blurred vision, confusion, or a high fever with a stiff neck.
Watch for signs of dehydration: excessive thirst, dark urine, dizziness when standing, dry mouth, and urinating much less than normal. These mean you’re losing fluids faster than you’re replacing them.
For timing: adults should see a doctor if vomiting lasts more than two days. For children under two, the threshold is 24 hours. For infants, it’s 12 hours. Recurring bouts of nausea and vomiting lasting longer than a month, or unexplained weight loss alongside vomiting, also warrant a medical visit to rule out underlying causes.
Helping a Child Who’s Throwing Up
Children dehydrate faster than adults because of their smaller fluid reserves. The same sip-by-sip approach applies, but use an oral rehydration solution (like Pedialyte) rather than water alone, since children lose proportionally more electrolytes. Offer a teaspoon every few minutes rather than letting them drink freely.
For babies who are breastfeeding, continue nursing in shorter, more frequent sessions. Formula-fed infants can have small amounts of rehydration solution between feedings. Don’t give young children sports drinks, fruit juice, or soda, as the sugar content can worsen diarrhea that often accompanies vomiting in kids. Popsicles made from rehydration solution are a practical trick for toddlers who refuse to sip from a cup.
