Medicine to prevent motion sickness

Motion sickness occurs when the brain receives mismatched information from the eyes, inner ear, and body about movement. Medicines can dampen balance signals or reduce the nausea response. They may cause drowsiness, dry mouth, blurred vision, or reduced alertness, depending on the product.

A tablet, patch, or other option may suit different journeys and medical histories. Motion sickness can still cause nausea, dizziness, sweating, and vomiting if exposure is strong or treatment is unsuitable.

Ask a pharmacist or clinician which product is suitable and when to take it. Do not drive, operate machinery, or drink alcohol until you know how it affects alertness. Check advice carefully for children, pregnancy, glaucoma, prostate symptoms, and other medicines.

Choose a seat with less movement, look toward the horizon, keep fresh air moving, and avoid reading during travel. Eat light food and sip fluids. If travel commonly causes vomiting, arrange a travel health consultation before departure.

Seek medical help for severe or persistent vomiting, inability to keep fluids down, fainting, confusion, severe headache, chest pain, or breathing difficulty. Get advice if dizziness continues after the journey, symptoms occur without movement, or the medicine causes marked sleepiness or vision changes.

Which option fits my journey and medical history? When should I take it, and how long might drowsiness last? What should I do if I still develop nausea or vomiting? Is another cause of dizziness worth checking?
