Fast-Acting Relief from Travel Sickness and Motion Sickness
Kwells Tablets Overview
Kwells Tablets are an antiemetic medicine used to prevent and relieve travel sickness and motion sickness, including nausea, vomiting and dizziness. They contain hyoscine hydrobromide, which works on the balance centres of the inner ear and the brain to reduce sickness symptoms.
In the UK, Kwells is an over-the-counter pharmacy medicine commonly used for car, sea and air travel.
Understanding Travel and Motion Sickness
What causes motion sickness
Motion sickness occurs when the brain receives conflicting signals from the eyes, inner ear and body movement. This sensory mismatch triggers symptoms such as nausea, vomiting, sweating and dizziness.
It is particularly common during car journeys, boat trips, flights and amusement rides, and can affect both adults and children.
Why prevention matters
Once nausea develops, it can be difficult to control. Medicines like Kwells are often most effective when taken before travel begins, helping prevent symptoms rather than trying to treat them after onset.
What Are Kwells Tablets?
Kwells Tablets contain hyoscine hydrobromide, an antimuscarinic medicine that reduces stimulation of the vomiting centre in the brain. It has been used for many years as an effective treatment for motion-related nausea.
The tablet form allows flexible dosing and fast absorption.
How Do Kwells Tablets Work?
Action on the balance system
Hyoscine works by blocking acetylcholine in the vestibular system (inner ear) and central nervous system. This reduces abnormal nerve signalling that leads to nausea and vomiting during motion.
Rapid onset of action
Kwells Tablets typically begin working within 20–30 minutes, making them suitable for short journeys as well as longer trips.
What Kwells Helps With — and What It Does Not
What it helps with
Kwells Tablets are used to prevent and relieve:
- travel sickness
- motion sickness
- nausea and vomiting related to movement
- dizziness associated with travel
They may also be used in other situations causing motion-related nausea, under professional advice.
What it does not treat
Kwells does not:
- treat nausea caused by infection or food poisoning
- cure vertigo from medical conditions
- prevent migraine-related nausea
- replace medical assessment for persistent vomiting
Ongoing or unexplained symptoms should be reviewed.
Who Are Kwells Tablets For?
Kwells Tablets may be suitable for:
- adults and children (age guidance applies)
- people prone to car, sea or air sickness
- individuals seeking fast-acting relief
- those needing short-term nausea prevention
A pharmacist can advise on correct dosing and suitability.
Who Should Avoid Kwells
Kwells Tablets should not be used if:
- you have glaucoma
- you have urinary retention or prostate problems
- you have gastrointestinal obstruction
- you are allergic to hyoscine
Caution is advised in older adults due to anticholinergic effects.
How to Take Kwells Tablets
Kwells Tablets are usually taken 20–30 minutes before travel, then repeated as directed if needed. Tablets should be swallowed whole with water.
Do not exceed the recommended dose. Alcohol should be avoided as it can increase side effects.
Safety, Warnings and Side Effects
Kwells is generally effective but may cause side effects such as dry mouth, blurred vision, drowsiness or dizziness due to its anticholinergic action.
If drowsiness occurs, avoid driving or operating machinery.
When to Seek Medical Advice
Speak to a GP or pharmacist if:
- symptoms persist despite treatment
- nausea occurs without travel
- side effects are troublesome
- the medicine is needed frequently
Further assessment may be required.
Use in Pregnancy and Breastfeeding
Kwells should be used during pregnancy or breastfeeding only on professional advice, as safety should be assessed individually.
How Kwells Compares to Other Travel Sickness Treatments
Kwells vs antihistamines
Some antihistamines can reduce motion sickness but often cause drowsiness. Kwells acts directly on the balance system and may be preferred for faster onset.
Kwells vs non-drug measures
Positioning, fresh air and avoiding reading can help, but medicines like Kwells provide more reliable symptom control for susceptible individuals.

Kwells Tablets (12 Tablets) provide fast, effective relief from travel and motion sickness by acting on the inner ear and brain to reduce nausea and vomiting. Taken before travel, they help prevent symptoms and improve comfort during journeys.
