Medicines and products for vomiting

The honest headline about vomiting medicines: the most important product is not a pill at all - it is ORS. Antiemetic drugs have their place, but only with the right drug, for the right patient, ideally on prescription.

ORS - the cornerstone. Oral rehydration solution replaces the water, salt and potassium vomiting removes. Low-osmolarity WHO-formula sachets are cheap, everywhere, and life-saving in children. This is the product every home should stock.

Antiemetics (vomit-stopping drugs):

• Ondansetron: effective for gastroenteritis vomiting, chemotherapy and post-operative nausea. In children it is used selectively (a doctor decides); in pregnancy only when the doctor judges benefits outweigh unknowns.
• Domperidone: common for nausea with bloating and slow stomach emptying. Long-term or high-dose self-medication is unsafe - it can disturb heart rhythm; use short courses on advice.
• Metoclopramide: similar territory, with movement-related side effects if misused - prescription drug.
• Doxylamine with B6: the established, evidence-backed combination for pregnancy nausea - under a doctor's guidance.
• Antihistamines (promethazine, cinnarizine, meclizine): mainly for motion sickness and vertigo; sedating - no driving after.

For children: antiemetics are mostly NOT recommended without a doctor; the treatment is ORS and time. Never give leftover adult antiemetics to a child.

What to avoid: self-prescribed antibiotics for 'stomach infection' (most are viral), painkillers on an empty stomach during a vomiting illness, and stopping essential medicines because of vomiting without medical advice.

Probiotics have modest evidence for shortening infectious diarrhoea-vomiting illnesses and are safe adjuncts.

Ayurvedic view (interpretive): classical antiemetic preparations exist within an interpretive framework of limited evidence; ginger preparations are the exception with genuine supporting evidence. None replaces ORS or prescription antiemetics when those are needed.

Remember: ORS first, always. Antiemetics are targeted tools - ondansetron selectively, domperidone briefly, pregnancy nausea via the doctor, motion sickness via antihistamines - and for children, fluids over pills.
