Several approaches can relieve nausea and vomiting, from simple tricks you can try in the next few minutes to over-the-counter medications and prescription options for more persistent cases. What works best depends on the cause, but a combination of small dietary changes, targeted remedies, and proper hydration resolves most episodes within a day or two.
Fast Relief: Breathing and Aromatherapy
One of the quickest ways to ease nausea costs almost nothing. Sniffing an isopropyl alcohol pad (a standard rubbing alcohol wipe) held about an inch below your nose provides peak relief within four minutes. In emergency department trials, patients who inhaled isopropyl alcohol saw their nausea scores drop from 50 out of 100 down to 20 after 30 minutes. That outperformed a commonly prescribed anti-nausea medication in the same study, and patients reported higher satisfaction with the alcohol pad approach. You can use multiple pads in a row since the effect is short-lived, and no adverse effects were reported. If you don’t have alcohol wipes handy, slow, controlled deep breathing on its own can help interrupt the nausea signal.
Ginger: Dosage That Actually Works
Ginger is one of the most studied natural remedies for nausea, and the effective dose is lower than most people expect. A large trial of 744 cancer patients found that 500 mg to 1,000 mg of ginger per day significantly reduced nausea severity. Higher doses (1,500 mg) did not improve results. That 500 mg dose is roughly a quarter teaspoon of ground ginger, or two standard 250 mg ginger capsules. Capsules, ginger chews, and ginger tea all deliver the active compounds, though capsules make dosing more precise. Start with the lower amount and see how you respond.
Acupressure at the Wrist
Pressing a specific point on the inner wrist, known as PC6, reduces nausea by about 32% compared to a sham treatment. That figure comes from a Cochrane review pooling 40 trials with nearly 5,000 participants. To find the point, place three fingers across your inner wrist starting at the crease where your hand meets your arm. The spot sits just below your index finger, between the two tendons. Press firmly with your thumb for two to three minutes. Sea-Band wristbands apply continuous pressure to this same point and are widely available at pharmacies.
Over-the-Counter Medications
Several types of OTC products target nausea through different pathways:
- Antihistamines like dimenhydrinate (Dramamine) and meclizine work especially well for motion sickness and inner-ear-related nausea. They block signals from the balance system in your ear to the vomiting center in your brain. Drowsiness is the main side effect.
- Bismuth subsalicylate (Pepto-Bismol) coats and calms the stomach lining. It’s a solid choice for nausea from overeating, mild food reactions, or stomach bugs. Not suitable for children under 12.
- Phosphorated carbohydrate solutions (sold as Emetrol) contain a mix of sugars and phosphoric acid that helps settle the stomach. These work for nausea from viral gastroenteritis, upset stomach, and motion sickness.
- Antacids and acid reducers help when nausea stems from acid reflux or indigestion rather than infection or motion.
Matching the product to the cause matters. Motion sickness responds best to antihistamines. Stomach bugs and food-related nausea respond better to bismuth subsalicylate or phosphorated carbohydrate solutions.
Prescription Options
When OTC remedies aren’t enough, doctors most commonly prescribe ondansetron (Zofran). It blocks the chemical signals that trigger the vomiting reflex in your brain and gut. It’s effective for nausea caused by chemotherapy, surgery, stomach infections in children, and opioid medications. The most common side effect is constipation. Oral doses don’t carry the heart rhythm concerns sometimes associated with higher intravenous doses.
Other prescription antiemetics target different brain receptors depending on the cause. Your doctor will choose based on whether the nausea comes from medications, surgery recovery, migraines, or another source.
What to Eat and Drink
You may have heard of the BRAT diet (bananas, rice, applesauce, toast), but it’s no longer recommended as a strict regimen. It lacks protein, calcium, vitamin B12, and fiber, and sticking to it for more than 24 hours can actually slow recovery, particularly in children. The American Academy of Pediatrics considers it too restrictive.
The useful principle behind BRAT still holds: eat soft, bland foods while your stomach is unsettled. But expand beyond those four items. Scrambled eggs, skinless chicken, cooked vegetables, and plain crackers are all gentle options that deliver more nutrition. Eat small portions rather than full meals, and return to your normal diet as soon as you feel able. Your body needs the nutrients to recover.
Staying hydrated matters more than eating when you’re actively vomiting. Take small, frequent sips rather than gulping large amounts. For a simple rehydration drink, the WHO recommends mixing 6 level teaspoons of sugar and half a teaspoon of salt into one liter of clean water. This ratio helps your intestines absorb fluid more efficiently than plain water. Store-bought oral rehydration solutions like Pedialyte follow a similar formula and are convenient if you have them on hand.
Nausea During Pregnancy
Pregnancy nausea affects up to 80% of pregnant people, and treatment options are more limited because of fetal safety concerns. The first-line approach recommended by the American College of Obstetricians and Gynecologists is vitamin B6, sometimes combined with doxylamine (the active ingredient in certain OTC sleep aids like Unisom SleepTabs). A typical doxylamine dose is 12.5 mg, which is half of a scored 25 mg tablet. Ginger at 500 to 1,000 mg daily and acupressure wristbands are also considered safe during pregnancy. Ondansetron is not recommended as a first-line treatment in pregnancy due to a slightly increased risk of oral clefts identified in one study.
Warning Signs That Need Medical Attention
Most nausea and vomiting resolves on its own, but certain symptoms signal something more serious. Vomit that contains blood, looks like coffee grounds, or appears green needs prompt evaluation. The same goes for signs of dehydration: very dark urine, dizziness when standing, dry mouth, or going many hours without urinating.
Call emergency services if nausea and vomiting come with chest pain, severe abdominal cramping, confusion, blurred vision, or a high fever with a stiff neck. For adults, vomiting that persists beyond two days warrants a doctor’s visit. For children under 2, the threshold is 24 hours, and for infants, 12 hours. Unexplained weight loss alongside recurring nausea over a month or more also deserves investigation.
