Several over-the-counter medications can help stop vomiting, including bismuth subsalicylate (Pepto-Bismol), antihistamines like dimenhydrinate (Dramamine) and meclizine, and phosphorated carbohydrate solutions (Emetrol). Which one works best depends on what’s causing your nausea. If vomiting is severe or won’t stop, prescription options are also available.
Over-the-Counter Medications
The most accessible options are sitting on pharmacy shelves right now, no prescription needed. Each one works a little differently, so matching the right product to your situation matters.
Bismuth subsalicylate (Pepto-Bismol) is one of the most widely used options for general stomach upset, including nausea, indigestion, and vomiting. The standard adult dose is 2 tablets or 2 tablespoons of the liquid every 30 minutes to one hour as needed, up to 16 tablets or 16 tablespoons of regular-strength liquid in 24 hours. It works well for nausea related to food, mild stomach bugs, or general digestive upset.
Antihistamines (Dramamine, meclizine) are the go-to choice when vomiting is triggered by motion sickness, vertigo, or inner-ear problems. These medications work by crossing into the brain and calming the signals that trigger the vomiting reflex. Dimenhydrinate (Dramamine) is taken at 50 to 100 mg and lasts about 8 hours, while meclizine lasts 8 to 24 hours at 25 to 50 mg. Both take roughly 2 hours to kick in, so they’re better as prevention than rescue. One important note: newer “non-drowsy” antihistamines like cetirizine (Zyrtec) and loratadine (Claritin) do not work for nausea because they’re specifically designed not to penetrate the brain.
Phosphorated carbohydrate solutions (Emetrol) are a sugar-and-phosphoric-acid liquid meant for quick, mild relief. Adults take one or two tablespoons, repeated every 15 minutes until the nausea stops, but you shouldn’t continue beyond 5 doses (one hour) without medical guidance.
Ginger: What the Evidence Shows
Ginger is the most studied natural remedy for nausea. Its active compounds, gingerols and shogaols, block the same type of serotonin receptors in the gut that prescription anti-nausea drugs target. That’s not folk medicine speculation; it’s a known pharmacological mechanism.
The clinical evidence is mixed but encouraging in specific circumstances. A systematic review of randomized trials found that taking up to 1 gram of ginger per day for four or more days significantly reduced acute vomiting compared to placebo. However, taking ginger once when you’re already throwing up is less clearly effective. Think of it as something that works better with consistent use over several days, like during pregnancy-related morning sickness or a course of chemotherapy, rather than as a one-time fix. Ginger tea, ginger chews, and capsules are all common delivery methods.
Prescription Options for Severe Vomiting
When over-the-counter products aren’t enough, doctors can prescribe stronger anti-nausea medications. The most commonly prescribed is ondansetron (Zofran), which blocks serotonin receptors that signal the brain’s vomiting center. It’s widely used for vomiting caused by surgery, chemotherapy, food poisoning, and stomach viruses. It works fast, especially in dissolving-tablet form, and is effective against both the initial wave of vomiting and the lingering nausea that can follow for hours or days. If you’re unable to keep anything down and OTC options aren’t cutting it, this is typically what an urgent care or emergency room visit will get you.
What to Eat and Drink While Recovering
What you put in your stomach matters just as much as what medication you take. After your last vomiting episode, wait at least 30 to 60 minutes before trying any fluids. This gives your stomach a chance to settle. Start with small sips of water, ice chips, or clear broth rather than gulping down a full glass.
You’ve probably heard of the BRAT diet: bananas, rice, applesauce, and toast. It’s a reasonable starting point for the first day or two, but there’s no reason to limit yourself to just those four foods. Brothy soups, oatmeal, boiled potatoes, crackers, and unsweetened dry cereal are equally easy on the stomach. Once you can keep bland foods down, transition to more nutritious options like cooked squash, carrots, sweet potatoes without skin, avocado, skinless chicken, fish, and eggs. These are still gentle on digestion but provide the protein and nutrients your body needs to recover.
Avoid dairy, greasy or fried foods, spicy dishes, alcohol, and caffeine until your stomach feels fully normal. Carbonated drinks are a personal call. Some people find flat ginger ale soothing, while others find the carbonation irritating.
Pregnancy and Children
Pregnancy limits your options. Many anti-nausea medications haven’t been well-studied in pregnant women, and some carry risks. Ginger (up to 1 gram daily) is one of the more commonly suggested approaches during pregnancy, and phosphorated carbohydrate solutions are also used for morning sickness at one to two tablespoons upon waking and every three hours as needed. Beyond that, your OB-GYN can prescribe specific medications that have been evaluated for safety during pregnancy. Don’t take bismuth subsalicylate while pregnant, as it contains a compound related to aspirin.
For children, the priority is preventing dehydration rather than stopping the vomiting itself. Oral rehydration solutions (like Pedialyte) in small, frequent sips are the standard approach. Over-the-counter anti-nausea medications intended for adults are not automatically safe for kids, and dosing varies significantly by age and weight.
Warning Signs That Need Medical Attention
Most vomiting resolves on its own within 24 hours. But certain symptoms alongside vomiting signal something more serious. Get to an emergency room if your vomit contains blood, looks like coffee grounds, or is green. Those colors indicate bleeding in the digestive tract or a possible bowel obstruction.
Also seek immediate care if vomiting comes with chest pain, severe abdominal cramping, a high fever with a stiff neck, confusion, blurred vision, or a sudden severe headache unlike any you’ve had before. Signs of dehydration are another red flag: excessive thirst, dark urine, very infrequent urination, dry mouth, and dizziness when you stand up. Dehydration can escalate quickly, especially in young children and older adults, and sometimes requires IV fluids to reverse.
