Several things reliably help with nausea, ranging from simple home remedies like ginger and peppermint to over-the-counter antihistamines and prescription medications. What works best depends on the cause. Motion sickness, pregnancy, post-surgical recovery, and stomach bugs each respond to slightly different approaches, but a handful of strategies help across nearly all of them.
Why You Feel Nauseated
Nausea starts in the brain, not the stomach. Your body has four separate systems that can trigger it: the digestive tract itself, a specialized area in the brainstem that monitors your blood for toxins, the balance organs in your inner ear, and higher brain centers involved in stress, anxiety, and pain. All four feed into a network of neurons in the brainstem that coordinates the queasy feeling, gagging, and ultimately vomiting.
The brainstem’s toxin detector sits outside the blood-brain barrier, meaning it can sample chemicals circulating in your bloodstream and spinal fluid directly. When it picks up something potentially harmful (medications, infections, metabolic byproducts), it fires signals that start the nausea cascade. This is why so many different situations, from food poisoning to chemotherapy to a hangover, produce the same miserable sensation.
Ginger
Ginger is one of the most studied natural remedies for nausea, and it genuinely works. A meta-analysis found that roughly 1,000 mg of ginger per day, taken for at least four days, reduced nausea better than placebo in pregnant women. For chemotherapy patients, doses of 500 mg to 1,000 mg significantly reduced acute nausea (the kind that hits within 24 hours of treatment), though it was less effective for delayed nausea that shows up days later.
You can get ginger through capsules, ginger chews, freshly grated ginger steeped in hot water, or even flat ginger ale (though most commercial ginger ales contain very little actual ginger). Capsules make it easiest to hit the 1,000 mg target. For motion sickness, the typical recommendation is 1,000 mg about an hour before travel.
Peppermint Oil Inhalation
Inhaling peppermint essential oil is surprisingly effective. A pooled analysis of clinical trials found that peppermint inhalation reduced post-surgical nausea scores significantly within two to six hours. In pregnancy studies, daily peppermint oil treatment lowered symptom severity at both 48 and 96 hours. The effect was even more pronounced in chemotherapy patients, where nausea scores dropped by more than two points on a standard scale at 48 and 72 hours compared to placebo.
The simplest method is placing a drop or two of peppermint oil on a cotton ball and holding it near your nose, breathing normally. Some hospitals now offer this to patients recovering from anesthesia.
Acupressure at the P6 Point
There’s a pressure point on your inner wrist called P6 (Neiguan) that can ease nausea when pressed firmly. To find it, hold your hand palm-up with fingers pointing toward the ceiling. 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 tendons you can feel running up your forearm, is P6. Press firmly with your thumb for two to three minutes.
Memorial Sloan Kettering Cancer Center recommends this technique for chemotherapy-related nausea. Wristbands designed to apply constant pressure to this point (often marketed for seasickness) work on the same principle.
What and How to Eat
When you’re nauseated, the goal is to avoid triggering your already-irritated digestive system. Stick to foods that are low in fat, low in fiber, mild in flavor, and easy to chew. The classic BRAT diet (bananas, rice, applesauce, toast) follows this logic, but you’re not limited to those four foods. Plain crackers, boiled potatoes, broth, and plain pasta all fit. Avoid greasy, spicy, or strongly scented foods.
Eating patterns matter as much as food choices. Small amounts eaten frequently work better than full meals. An empty stomach can actually worsen nausea because stomach acid has nothing to work on, so nibbling a few crackers every hour or two often helps more than waiting until you feel “ready” to eat. Cold or room-temperature foods tend to be better tolerated than hot foods because they produce less aroma.
Staying Hydrated
Dehydration is the most common complication when nausea leads to vomiting, and it can create a vicious cycle since dehydration itself makes nausea worse. Small, frequent sips work better than drinking a full glass at once. If you’ve been vomiting, plain water alone isn’t ideal because you’ve lost electrolytes too.
Oral rehydration solutions are specifically designed for this situation. The World Health Organization formula uses a nearly equal ratio of glucose to sodium (75 milliequivalents of sodium per liter with 13.5 grams of carbohydrate) at a low osmolality of 245 mOsm/L, which maximizes fluid absorption. Commercial products like Pedialyte approximate this ratio. In a pinch, diluted fruit juice with a pinch of salt, or alternating sips of broth and water, can help replace what you’ve lost.
Over-the-Counter Medications
Several OTC options target nausea through different pathways. Antihistamines like dimenhydrinate (Dramamine) and meclizine (Bonine) block histamine receptors involved in the nausea response. They’re particularly effective for motion sickness and inner-ear-related nausea. The tradeoff is drowsiness, though meclizine tends to cause less sedation than dimenhydrinate.
Bismuth subsalicylate (Pepto-Bismol) works differently, coating the stomach lining and reducing irritation. It’s better suited for nausea from stomach upset, mild food poisoning, or overindulgence rather than motion sickness. Antacids can help if your nausea is tied to acid reflux.
Prescription Options
When OTC remedies aren’t enough, doctors most commonly prescribe medications that block serotonin receptors in the gut and brain. Your digestive tract releases serotonin when it’s irritated or damaged, and that serotonin activates receptors that trigger the nausea signal. Blocking those receptors interrupts the process. These medications are standard for preventing nausea after surgery, during chemotherapy, and after radiation therapy. They’re sometimes prescribed off-label for severe pregnancy nausea, though safety data in pregnancy is limited.
For pregnancy-related nausea specifically, a combination of vitamin B6 and the antihistamine doxylamine is a first-line prescription treatment. It’s available as a delayed-release tablet, typically started at two tablets at bedtime, with the dose gradually increased over several days if symptoms persist, up to a maximum of four tablets daily. Vitamin B6 on its own (typically 25 mg taken three times a day) is often tried first before adding doxylamine.
Warning Signs That Need Medical Attention
Most nausea resolves on its own or responds to the approaches above. But certain combinations of symptoms signal something more serious. Seek emergency care if nausea and vomiting occur alongside chest pain, severe abdominal cramping, blurred vision, confusion, a high fever with a stiff neck, or rectal bleeding.
You should also get prompt medical attention if your vomit contains blood, looks like coffee grounds, or is green. Signs of significant dehydration (dark urine, dizziness when standing, dry mouth, infrequent urination) mean you need help rehydrating, possibly with IV fluids. Nausea paired with a sudden severe headache, especially one unlike any you’ve had before, also warrants an urgent evaluation.
