Understanding Vomiting and When to Act
Vomiting is the forceful expulsion of stomach contents and is typically preceded by a feeling of nausea. It is often a protective reflex to rid the body of harmful substances. However, prolonged or severe vomiting can lead to complications, primarily dehydration. For most adults, vomiting from a common stomach bug will resolve within a day or two with at-home care. However, certain symptoms warrant immediate medical attention, including:
- Vomiting for more than 48 hours.
- Being unable to keep down fluids for 12 hours or more.
- Signs of severe dehydration, such as excessive thirst, infrequent or dark urine, dry mouth, or dizziness upon standing.
- Vomit containing blood or resembling coffee grounds.
- Vomiting accompanied by a severe headache, stiff neck, or chest pain.
Over-the-Counter Medications
For mild to moderate cases, several over-the-counter (OTC) medications can provide relief. These antiemetics work in different ways to help calm the stomach and stop the vomiting reflex.
- Bismuth subsalicylate (e.g., Pepto-Bismol): This medication protects the stomach lining and reduces irritation, making it effective for nausea and vomiting caused by gastrointestinal issues.
- Dimenhydrinate (e.g., Dramamine): As an antihistamine, it is primarily used for preventing and treating nausea, vomiting, and dizziness associated with motion sickness.
- Meclizine (e.g., Bonine, Dramamine Less Drowsy): Another antihistamine effective for motion sickness, often preferred by those who want to avoid the sedative effects of dimenhydrinate.
- Phosphorated carbohydrate solution (e.g., Emetrol): This medication is specifically designed to calm the stomach and relieve nausea caused by upset stomachs or overindulgence in food and drink.
Prescription Antiemetics
In more severe cases or for specific medical conditions, a healthcare provider may prescribe a stronger antiemetic.
- Ondansetron (Zofran): This serotonin antagonist is highly effective for nausea and vomiting caused by chemotherapy, radiation, or surgery. It works by blocking serotonin receptors in the brain and gut.
- Metoclopramide (Reglan): A dopamine antagonist that stimulates movement in the stomach and intestines, often used for conditions like gastroparesis and for chemotherapy-induced vomiting.
- Promethazine (Phenergan): An antihistamine sometimes prescribed for severe nausea and vomiting, though it can cause significant drowsiness.
- Scopolamine (Transderm Scop): An anticholinergic medication that is available as a patch, primarily used to prevent nausea and vomiting from motion sickness or post-surgical anesthesia.
Natural Remedies and At-Home Strategies
Before reaching for medication, several natural methods can effectively soothe an upset stomach.
Hydration and Diet Staying hydrated is crucial, especially after vomiting. Sip on small amounts of clear liquids to avoid overwhelming your stomach.
- Sip clear fluids: Water, broth, clear sodas (flat), and sports drinks with electrolytes can prevent dehydration.
- Suck on ice chips or popsicles: This can be easier to tolerate than drinking large amounts of liquid.
- Follow the BRAT diet: Bananas, rice, applesauce, and toast are bland foods that are easy to digest.
- Eat smaller, more frequent meals: This puts less strain on your digestive system.
Herbal and Aromatherapy
- Ginger: This traditional remedy is known for its anti-nausea properties. You can consume it as ginger tea, ginger candy, or supplements.
- Peppermint: The aroma of peppermint oil can help reduce feelings of nausea. It can be inhaled or consumed as peppermint tea.
- Lemon: The refreshing scent of lemon, or adding a slice to water, can also help alleviate nausea.
Lifestyle Adjustments
- Rest: Take it easy and avoid vigorous activity, which can worsen nausea.
- Fresh air: Stepping outside or rolling down a car window can sometimes provide relief from nausea.
- Acupressure: Applying pressure to the P-6 acupressure point on the wrist can help alleviate symptoms.

What to Avoid While Vomiting
To aid your recovery and avoid aggravating your stomach, it is important to steer clear of certain things.
- Greasy, fried, and spicy foods: These are difficult to digest and can irritate the stomach lining.
- Strong odors: Cooking smells, perfumes, and other strong scents can trigger a gag reflex.
- Caffeine and alcohol: These substances can further irritate your stomach and contribute to dehydration.
- Dairy products: For some people, dairy can increase gassiness and diarrhea.
- Chugging fluids: Drinking too quickly can re-trigger vomiting.
Conclusion
For most adults, mild vomiting can be managed effectively with simple at-home strategies, including staying hydrated with small sips of clear fluids, eating bland foods like those in the BRAT diet, and incorporating herbal remedies such as ginger or peppermint. Over-the-counter medications like Pepto-Bismol and Dramamine offer targeted relief for specific causes like GI upset or motion sickness. For more severe or persistent symptoms, a doctor may prescribe stronger antiemetics, such as ondansetron. Knowing what can adults take to stop vomiting involves assessing the cause and severity of symptoms while being aware of the red flags that signal a need for professional medical evaluation. For ongoing or severe issues, always consult a healthcare provider for a proper diagnosis and treatment plan. For further reading on nausea and vomiting, visit MedlinePlus.
