What should you know about OTC medicines to help with nausea?

Nausea is a symptom rather than a diagnosis. It may occur with food poisoning, gastroenteritis, acid reflux, gastritis, heat exhaustion, low blood sugar, or other problems. An anti-sickness product may reduce the sensation without treating the trigger. Some products cause drowsiness, dry mouth, constipation, or interactions, so a pharmacist should check suitability if you are pregnant, older, treating a chronic condition, or taking regular medicines.

Take small, frequent sips of water or an oral rehydration drink and choose bland foods when you can tolerate them. Avoid alcohol, heavy meals, and strong smells while symptoms are active. Use only a product intended for your age group and follow its label. Do not combine two anti-sickness products without professional advice. Note when nausea began, possible food exposures, vomiting, pain, fever, and medicines taken; this helps a clinician identify the cause.

Seek urgent care for severe abdominal pain, chest pain, confusion, fainting, blood in vomit, a stiff neck, or inability to keep fluids down. Get prompt advice for signs of dehydration, yellowing of the skin or eyes, suspected heat illness, or nausea that keeps returning. Children, pregnant people, and people with diabetes or significant medical conditions may need earlier assessment.

Ask what may be causing the nausea, whether an OTC product is suitable with your medicines, and how to recognise dehydration or another warning sign.
