Nausea can often be managed at home with a combination of dietary changes, natural remedies, over-the-counter medications, and simple physical techniques. The best approach depends on what’s causing it, but most episodes respond well to small, practical interventions you can start immediately.
Start With What You Eat and Drink
When you’re nauseous, your instinct may be to avoid food and drink entirely. That’s fine briefly, but staying hydrated matters, especially if you’ve been vomiting. The key is starting extremely small: one teaspoon of clear liquid every 10 minutes, gradually increasing to one tablespoon every 20 minutes, then two tablespoons every 30 minutes as your stomach settles.
Good options for those first sips include water, apple juice, white grape juice, low-salt broth, ginger ale, plain gelatin, or an electrolyte drink like Pedialyte or Gatorade. Once clear liquids stay down, move to soft bland foods: mashed potatoes, rice, pureed fruits, yogurt, or cereal with milk. Cold or room-temperature foods tend to work better than hot ones because they produce less smell, which can retrigger nausea.
Throughout the process, eat small amounts every few hours rather than full meals. Sip liquids slowly through a straw rather than gulping. Avoid anything fried, greasy, spicy, or strongly flavored. Dry saltine crackers, plain toast, and pretzels are reliable standbys when you’re testing whether your stomach is ready for solids.
Ginger: The Best-Studied Natural Remedy
Ginger has genuine anti-nausea effects. In animal studies, it speeds up the movement of food through the digestive tract and blocks serotonin receptors in the gut, the same pathway that prescription anti-nausea drugs target. Clinical trials in humans have tested doses ranging from 250 mg to 2 g per day, split into three or four portions. Notably, 1 g per day worked just as well as 2 g, so more isn’t necessarily better.
You don’t need capsules to get this benefit. Ginger tea (fresh sliced ginger steeped in hot water, then cooled to lukewarm), ginger chews, or flat ginger ale all deliver the active compounds. If you prefer a standardized dose, ginger supplements are widely available in 250 mg capsules.
Peppermint Inhalation
Inhaling peppermint oil is a surprisingly effective technique. In a clinical trial of surgical patients, those who inhaled peppermint aromatherapy had significantly less nausea in the 24 hours afterward (about 53%) compared to those who didn’t (about 74%). The benefit was strongest in the first hour. Peppermint’s active ingredient, menthol, works through two routes: it acts on the brain’s emotional processing centers through the olfactory pathway, and it relaxes the smooth muscle of the digestive tract, reducing the spasms that contribute to the urge to vomit.
The simplest approach is putting a drop or two of peppermint essential oil on a tissue or cotton ball and breathing it in slowly. Peppermint tea, cooled to lukewarm, combines the aromatherapy benefit with gentle hydration.
Acupressure at the P6 Point
There’s a pressure point on your inner wrist called P6 (or Neiguan) that has been used in clinical settings, including at Memorial Sloan Kettering Cancer Center, for nausea relief. To find it, hold your hand with your palm facing you and fingers pointing up. Place three fingers from your other hand across your wrist, just below the crease where your wrist bends. The spot directly below your index finger, between the two large tendons you can feel there, is P6.
Press firmly with your thumb for two to three minutes, then repeat on the other wrist. This is the same principle behind the anti-nausea wristbands sold for motion sickness and morning sickness. It won’t work for everyone, but it’s free, has no side effects, and can be done anywhere.
Over-the-Counter Medications
Several categories of OTC drugs target nausea, and the right choice depends on the cause.
- Antihistamines for motion sickness: Meclizine (Bonine), dimenhydrinate (Dramamine), and diphenhydramine (Benadryl) all work by calming the vestibular system, the part of your inner ear that senses motion. They’re most effective when taken before the motion starts. Drowsiness is the main side effect.
- Bismuth subsalicylate for stomach upset: The active ingredient in Pepto-Bismol coats the stomach lining and reduces irritation. For nausea from overeating, food that didn’t agree with you, or a stomach bug, it’s a solid option. The standard dose is two chewable tablets every half hour as needed, up to a maximum of 16 tablets (eight doses) in 24 hours. Don’t use it for more than two days running.
- Antacids for acid-related nausea: If your nausea comes with heartburn or a sour taste, the cause may be stomach acid. A basic antacid or an acid-reducing tablet can resolve the nausea by addressing the underlying irritation.
- Phosphorated carbohydrate solutions: Products like Emetrol contain a sugar and phosphoric acid mixture that can calm the stomach muscles. These work for nausea from stomach flu or motion sickness and are available without a prescription.
Pregnancy Nausea
Morning sickness affects the majority of pregnant people, typically in the first trimester. Vitamin B6 is the most commonly recommended first-line option. The American College of Obstetricians and Gynecologists also recognizes the combination of vitamin B6 with doxylamine, an antihistamine found in some over-the-counter sleep aids (half of a 25 mg scored tablet provides the standard 12.5 mg dose). This combination has been studied extensively and has a long safety record in pregnancy.
Ginger is also considered safe during pregnancy at the doses described above. The same dietary strategies apply: small frequent meals, bland foods, and steady sipping of clear fluids. Many pregnant people find that eating a few crackers before getting out of bed in the morning helps prevent the wave of nausea that hits on an empty stomach.
When Nausea Needs More Than Home Care
For severe or persistent nausea, such as that caused by chemotherapy, surgery, or chronic conditions, doctors can prescribe stronger medications. The most widely used class works by blocking serotonin from binding to specific receptors in the gut and brainstem. Serotonin is the chemical messenger that triggers the vomiting reflex, and these drugs intercept the signal before it reaches the brain’s vomiting center. These prescriptions are highly effective but require a doctor’s evaluation.
Rehydrating After Vomiting
If you’ve been vomiting, replacing lost fluids and electrolytes is critical. Plain water alone isn’t ideal because it lacks the sodium and sugar your body needs to absorb fluid efficiently. The World Health Organization’s oral rehydration formula is simple to make at home: 4 and a quarter cups of water, half a teaspoon of salt, and 2 tablespoons of sugar. Stir until dissolved and sip slowly.
If you don’t want to measure, you can approximate by adding half a teaspoon of salt to 4 cups of a diluted sports drink (mix 1.5 cups of regular Gatorade or Powerade with 2.5 cups of water). Broth-based versions work too: dissolve one regular-sodium bouillon cube in 4 cups of water with a quarter teaspoon of salt and 2 tablespoons of sugar. The goal is small, steady sips rather than large gulps, which can trigger vomiting again.
Warning Signs That Need Urgent Attention
Most nausea resolves on its own or with the strategies above. But certain combinations of symptoms signal something more serious. Get to an emergency room or urgent care if your nausea and vomiting come with chest pain, severe abdominal cramping, blurred vision, confusion, high fever with a stiff neck, or rectal bleeding. Vomit that contains blood, looks like coffee grounds, or is green also warrants immediate evaluation.
Dehydration itself can become dangerous. Signs include excessive thirst, dark urine, infrequent urination, dry mouth, and dizziness when you stand up. If you can’t keep any fluids down for an extended period and notice these symptoms, you likely need IV fluids, which means a trip to a medical facility.
