What should you know about medicine for avoiding vomiting while travelling?

Motion sickness happens when signals from the eyes and balance organs do not agree during travel. Medicines used for prevention may reduce these signals, while others calm nausea. They work best when taken before the journey and may cause sleepiness, dry mouth, blurred vision, or reduced alertness.

Vomiting during a trip can also come from infection, food, migraine, or another illness. [Vomiting](/symptoms/vomiting/) that begins with fever, diarrhoea, severe pain, or a new headache should not be assumed to be motion sickness.

Ask a pharmacist which product suits your age, health conditions, and other medicines. Follow the package directions and test a dose only when you do not need to drive or operate equipment. Choose a seat with less movement, look toward the horizon, keep air flowing, and take small sips of fluid.

Avoid heavy meals and alcohol before travel. Do not combine sedating products unless a clinician advises it. Children, pregnant people, and adults with glaucoma, urinary problems, or breathing conditions should get individual advice before using these medicines.

Get urgent medical help for blood or green vomit, severe or worsening abdominal pain, a stiff neck, confusion, fainting, chest pain, or signs of dehydration such as very little urine. Persistent vomiting after travel also warrants assessment because [Food Poisoning](/conditions/food-poisoning/) and [Gastroenteritis](/conditions/gastroenteritis/) need different care.

Ask when to take the medicine, how long its effect lasts, whether drowsiness is expected, and what to do if you vomit after taking it. Mention pregnancy, children travelling, and every regular medicine.
