What should you know about vomit nausea medicine?

Nausea and vomiting can happen with gastroenteritis, food poisoning, acid reflux, gastritis, gallstones, heat exhaustion, hepatitis A, or low blood sugar. The right treatment may therefore involve rehydration, correcting blood sugar or heat illness, treating irritation, or using a prescribed anti-sickness medicine. Some products are unsuitable with particular illnesses or medicines and can cause drowsiness, so a pharmacist or clinician should help you choose safely.

Vomiting can remove fluids and salts from the body. Small, frequent sips may be easier to keep down than a large drink. If you cannot keep fluids down, the concern is dehydration and the underlying cause needs assessment rather than repeated self-treatment.

Rest, take small sips of water or an oral rehydration drink, and eat bland food only when you feel able. Avoid alcohol and foods that clearly trigger symptoms. Check with a pharmacist before using an anti-sickness product, especially for a child, during pregnancy, with glaucoma, heart-rhythm problems, or when taking sedating medicines. Do not double doses or use someone else's prescription. Keep track of how often you vomit and whether you are passing urine.

Arrange prompt medical advice if vomiting persists, keeps returning, or leaves you unable to drink, or if you have signs of dehydration such as very little urine, marked dizziness, or unusual drowsiness. Seek emergency help for blood or coffee-ground material in vomit, severe abdominal pain, stiff neck, confusion, fainting, breathing difficulty, or suspected poisoning. Heat-related illness and low blood sugar can also need urgent treatment.

Ask what may be causing the vomiting, whether you need an anti-sickness medicine, and how to take it safely with your current medicines. Ask how much fluid to take, which symptoms require urgent review, and whether testing is needed.
