Medicines for nausea

Some anti-sickness medicines calm signals between the stomach and brain; others help the stomach move food onward. A clinician may choose differently for a stomach infection, migraine, motion sickness, pregnancy, or a medicine side effect. Nausea can also accompany Acid Reflux, Food Poisoning, Gallstones, Gastritis, Gastroenteritis, Heat Exhaustion, Hepatitis A, or Hypoglycaemia.

Side effects vary. Sleepiness, dry mouth, blurred vision, constipation, or dizziness can occur with some products. Avoid driving or alcohol until you know how a medicine affects you, and do not combine products with similar ingredients without advice.

A pharmacist can check symptoms, current medicines, and suitable formulations. Take only the labelled or prescribed dose. Sip clear fluids regularly, choose small bland meals when able, and avoid strong smells or rich foods if they worsen symptoms. Do not stop a prescribed medicine suddenly; ask the prescriber whether nausea could be a side effect or whether timing can change.

Seek urgent help for severe or worsening abdominal pain, confusion, fainting, blood or coffee-ground material in vomit, green vomit, a stiff neck with severe headache, or inability to keep fluids down. Arrange medical advice when nausea persists, returns often, causes weight loss, or occurs with signs of dehydration such as very little urine, marked thirst, or light-headedness.

Ask what may be causing the nausea, how long to use the medicine, which side effects require action, and whether it interacts with your regular treatment or is suitable during pregnancy, breastfeeding, or childhood.
