Over-the-counter nausea remedies: what to know

Nausea may come from a stomach infection, food poisoning, reflux, motion, heat, low blood sugar or a medicine. Vomiting and diarrhoea can remove fluid and salts, while abdominal pain or fever may point to an illness needing assessment. [Gallstones](/conditions/gallstones/) and [Hepatitis A](/conditions/hepatitis-a/) are examples of conditions in which nausea can occur, so symptom relief should not delay care when other symptoms are concerning.

Sip fluids often rather than drinking a large amount at once. Once settled, choose small portions of simple food and avoid alcohol, rich meals and strong smells. A pharmacist can help compare an antacid, rehydration product or other remedy with your medicines and medical history. Read active ingredients and directions carefully; seek advice before treating a child, an older adult, or someone who is pregnant or has a long-term condition. Keep prescribed medicines separate from self-care products unless a professional confirms the combination is suitable.

Seek urgent care for severe abdominal pain, fainting, confusion, chest pain, blood in vomit, a rigid abdomen or marked dehydration. Contact a clinician if symptoms do not settle, fluids will not stay down, vomiting repeatedly returns, or nausea comes with yellow skin or eyes. Nausea with overheating, weakness or confusion may signal [Heat Exhaustion](/conditions/heat-exhaustion/).

Ask which cause is most plausible, whether you need fluid replacement, which ingredient is appropriate, and how long you should self-treat before arranging a review.
