What should you know about OTC nausea relief?

Nausea may accompany acid reflux, gastritis, food poisoning, gastroenteritis, gallstones, heat exhaustion, hepatitis A, or hypoglycaemia. Treating the feeling alone can hide a worsening problem. Antacids may help when burning reflux is the trigger, while anti-sickness products act on nausea pathways; neither is a universal remedy. Product effects and interactions vary, particularly with sedating medicines.

Rest in a cool, well-ventilated place and take small sips of water or an oral rehydration drink. Eat small portions of plain food when ready, and avoid rich meals, alcohol, and strong odours. Read the active ingredients before taking anything, and ask a pharmacist to check it against your medicines and health history. Keep track of vomiting, pain, fever, bowel changes, and urine output.

Get urgent care for severe or localised abdominal pain, blood in vomit or stool, fainting, confusion, severe headache, yellow skin or eyes, or inability to retain fluids. Prompt assessment is also needed for signs of dehydration, suspected low blood sugar, heat illness, or symptoms that recur without an obvious trigger. Do not keep escalating OTC doses when the cause is unclear.

Ask what cause is most plausible, which relief option is safe with your medicines, and how long you should monitor symptoms before arranging a review.
