Are Kwells Travel Sickness Tablets Right for You?

 

If the thought of a long car journey, a choppy ferry crossing, or a winding mountain road fills you with dread, you are not alone. Motion sickness affects a significant number of people in the UK, and it can turn what should be an enjoyable trip into a genuinely miserable experience. Kwells travel sickness tablets are a well-established, over-the-counter option that can help prevent and relieve the nausea, dizziness, and vomiting associated with travel. Each pack contains 12 tablets, making it a practical choice to keep in your bag before any journey. You can browse the full range of travel health products in our travel collection at Cured Pharmacy.

Each tablet contains 300 micrograms of hyoscine hydrobromide as the active ingredient. Hyoscine is one of the most widely used medicines for motion sickness and has a long track record of clinical use. The tablets can be swallowed whole or dissolved under the tongue, which is particularly useful if you are already feeling queasy and struggling to swallow.

 

How Do Kwells Tablets Work to Prevent Motion Sickness?

 

Motion sickness happens when your brain receives conflicting signals — your eyes might tell it you are sitting still, while your inner ear senses movement. This mismatch triggers the nausea and vomiting response. Hyoscine hydrobromide works by blocking muscarinic receptors in the central nervous system, specifically interrupting the nerve signals that travel between the vestibular system (your inner ear balance organs) and the vomiting centre in the brain.

  • Hyoscine crosses the blood-brain barrier and acts centrally to reduce vestibular stimulation.
  • It blocks acetylcholine at muscarinic receptors, dampening the signals that trigger nausea.
  • Effects begin within 30 minutes of taking the tablet, making pre-journey timing important.
  • Each dose lasts approximately four to six hours, covering most short-to-medium journeys.

 

Who Is Kwells Suitable For?

 

Kwells tablets are suitable for adults and children aged 10 years and over. They are particularly useful for people who experience nausea or vomiting on car journeys, boat trips, coach travel, or flights. If you have tried other remedies without success, hyoscine hydrobromide offers a different mechanism of action to antihistamine-based alternatives, which some people find more effective.

  • Adults and teenagers aged 10 and over who experience motion sickness.
  • Travellers who need a fast-acting, short-duration remedy for journeys up to six hours.
  • People who prefer a tablet that can be dissolved under the tongue rather than swallowed.
  • Those who have not responded well to antihistamine-based travel sickness medicines.

If you are unsure whether Kwells are appropriate for your specific health situation — for example, if you have glaucoma, an enlarged prostate, or a heart condition — it is always worth speaking to a pharmacist before purchasing.

Specifications of Kwells Travel Sickness 12 Tablets

 

What Is Kwells and What Is It Used For?

 

Kwells Travel Sickness Tablets are an over-the-counter medicine used to prevent and relieve the symptoms of motion sickness. These symptoms include nausea, vomiting, and dizziness that occur during travel by car, boat, plane, or coach. The active ingredient is hyoscine hydrobromide 300 micrograms per tablet. Kwells are licensed for use in adults and children aged 10 years and over and are available without a prescription from UK pharmacies.

 

What Do You Need to Know Before Using Kwells?

 

Before taking Kwells, it is important to check whether this medicine is appropriate for you. There are certain conditions and medicines that may make Kwells unsuitable or require extra caution.

Do not take Kwells if you:

  • Are allergic to hyoscine hydrobromide or any other ingredient in the tablet.
  • Have narrow-angle glaucoma (increased pressure in the eye).
  • Have myasthenia gravis (a condition causing muscle weakness).
  • Are under 10 years of age.
  • Have difficulty passing urine (urinary retention).

Take care and speak to a pharmacist or doctor if you:

  • Have an enlarged prostate gland.
  • Have a bowel obstruction or other gastrointestinal problems.
  • Have epilepsy or a history of seizures.
  • Are pregnant or breastfeeding — seek medical advice before use.
  • Are elderly, as you may be more sensitive to anticholinergic effects.

Medicines that may interact with Kwells:

  • Alcohol — increases sedative effects; avoid drinking during treatment.
  • Antihistamines (e.g. chlorphenamine) — combined anticholinergic effects may be enhanced.
  • Tricyclic antidepressants (e.g. amitriptyline) — increased risk of anticholinergic side effects.
  • Other anticholinergic medicines — additive effects possible.
  • Sedatives or sleeping tablets — increased drowsiness risk.

 

How Should You Use Kwells Tablets?

 

Always read the patient information leaflet supplied with your pack before taking Kwells. Follow the dosage instructions carefully and do not exceed the maximum recommended dose in any 24-hour period.

  1. Take the tablet 20 to 30 minutes before your journey begins.
  2. Swallow the tablet whole with water, or place it under your tongue to dissolve (sublingual use).
  3. If symptoms persist during a long journey, a further dose may be taken after six hours.
  4. Do not take more than three tablets in any 24-hour period.
  5. Do not drive or operate heavy machinery after taking Kwells, as drowsiness may occur.
Age Group Dose Frequency Maximum in 24 hours
Adults and children aged 10+ 1 tablet (300 micrograms) Every 6 hours as needed 3 tablets
Children under 10 years Not suitable

If you are travelling with younger children and need suitable remedies, you may find helpful options in our baby and toddler collection — though always confirm suitability with a pharmacist first.

 

What Are the Possible Side Effects of Kwells?

 

Like all medicines, Kwells can cause side effects, although not everyone experiences them. Most side effects are related to the anticholinergic action of hyoscine hydrobromide and are generally mild.

Common side effects:

  • Drowsiness or sedation
  • Dry mouth
  • Blurred vision
  • Dizziness

Less common side effects:

  • Difficulty urinating
  • Constipation
  • Increased heart rate (tachycardia)
  • Skin flushing
  • Confusion or disorientation (more likely in elderly patients)
  • Allergic reactions such as skin rash

If you experience a fast or irregular heartbeat, severe confusion, difficulty breathing, or signs of an allergic reaction (swelling of the face, lips, or throat), stop taking Kwells immediately and seek urgent medical attention.

 

How Should You Store Kwells Tablets?

 

  • Store below 25°C in a dry place away from direct heat and sunlight.
  • Keep the tablets in their original blister packaging until use.
  • Keep out of the sight and reach of children.
  • Do not use after the expiry date printed on the pack.
  • Do not dispose of medicines via wastewater or household waste — return unused tablets to your pharmacy.

Frequently Asked Questions

Where can I buy Kwells travel sickness tablets online in the UK?

You can buy Kwells Travel Sickness 12 Tablets directly from Cured Pharmacy, a GPhC-registered UK online pharmacy, for just £3.99. They are classed as a General Sale List medicine, meaning no prescription is needed. You can also browse our full travel collection for other journey essentials.

How do Kwells travel sickness tablets work in the body?

Kwells contain hyoscine hydrobromide, which is an anticholinergic medicine that crosses the blood-brain barrier and blocks muscarinic receptors in the central nervous system. This interrupts the nerve signals sent from the inner ear's vestibular system to the brain's vomiting centre, reducing the sensation of nausea. The result is that the conflicting sensory signals that cause motion sickness are effectively dampened before they trigger symptoms.

How do I take Kwells tablets step by step?

Take one Kwells tablet 20 to 30 minutes before your journey starts — this gives the medicine time to be absorbed and take effect. You can either swallow the tablet whole with water or place it under your tongue to dissolve, which is useful if you are already feeling unwell. Do not take more than three tablets in any 24-hour period, and leave at least six hours between doses.

When is the best time to take Kwells before travelling?

The best time to take Kwells is 20 to 30 minutes before you begin your journey, while you are still feeling well. Taking the tablet after nausea has already started is significantly less effective, as the medicine works best as a preventative rather than a cure. If you are going on a long journey, you can take a further tablet after six hours if needed.

What are the side effects of Kwells tablets and how do I manage them?

The most common side effects of Kwells are drowsiness, dry mouth, and blurred vision — these are typical of anticholinergic medicines and usually mild. To manage drowsiness, avoid alcohol and do not drive or operate machinery after taking a tablet. If you experience more serious effects such as a rapid heartbeat, difficulty urinating, or confusion, stop taking the tablets and speak to a pharmacist or GP.

Who is eligible to take Kwells travel sickness tablets?

Kwells are suitable for adults and children aged 10 years and over who experience nausea, vomiting, or dizziness during travel. They are not suitable for children under 10, people with narrow-angle glaucoma, those with urinary retention, or anyone with myasthenia gravis. If you are pregnant, breastfeeding, or taking other medicines, speak to a pharmacist before use.

Can children take Kwells tablets for travel sickness?

Kwells tablets are suitable for children aged 10 years and over at the same dose as adults — one tablet up to three times in 24 hours. They are not licensed for use in children under 10, so a different product would be needed for younger children. Always supervise children when taking any medicine and keep tablets out of their reach at all times.

What happens if I miss a dose of Kwells during a journey?

If you forget to take a Kwells tablet before your journey and symptoms have not yet started, take one as soon as you remember — provided at least six hours have passed since any previous dose. Do not take two tablets at once to make up for a missed dose. If you have already taken three tablets in the past 24 hours, wait until the following day before taking any more.

What are the alternatives to Kwells for motion sickness?

Common alternatives include antihistamine-based tablets such as cinnarizine (Stugeron) or promethazine (Phenergan), which work via a different mechanism and may suit people who cannot take anticholinergic medicines. For longer journeys, hyoscine patches (Scopoderm) deliver the same active ingredient through the skin over 72 hours. You can explore related options in our sickness and nausea collection.

Can I drink alcohol while taking Kwells tablets?

No — you should avoid alcohol while taking Kwells, as it significantly increases the sedative effects of hyoscine hydrobromide and raises the risk of drowsiness and impaired coordination. This is particularly important if you are driving to a port or airport before boarding a ferry or flight. Even small amounts of alcohol can enhance the sedative effect, so it is safest to avoid it entirely during treatment.

Are Kwells tablets safe to take during pregnancy?

Kwells are not recommended during pregnancy without medical advice, as the safety of hyoscine hydrobromide in pregnancy has not been fully established. If you are pregnant and experiencing travel sickness, speak to your GP or midwife before taking any medicine. They can advise on the safest options for your individual circumstances.

How long do the effects of Kwells tablets last?

Each Kwells tablet provides protection against motion sickness for approximately four to six hours, making it well suited to short-to-medium length journeys. For longer trips, a further tablet can be taken after six hours, up to a maximum of three tablets in 24 hours. If your journey exceeds 24 hours, speak to a pharmacist about whether continued use is appropriate.

How long can you keep taking Kwells for travel sickness?

Kwells are intended for short-term use during travel and should not be taken continuously for extended periods without medical guidance. The maximum dose is three tablets per 24 hours, and use should be limited to the duration of your journey. If you find you need motion sickness medication very frequently, it is worth discussing longer-term options with your GP.

What does the latest research say about hyoscine for motion sickness?

Hyoscine hydrobromide remains one of the most clinically studied and widely recommended medicines for motion sickness, with evidence supporting its effectiveness in reducing nausea and vomiting during travel. The NHS lists it as a first-line treatment option for motion sickness in adults and children aged 10 and over. Research continues to confirm that it acts faster than antihistamine alternatives, though it has a shorter duration of action.

Can I take Kwells with other medicines I am already using?

Kwells can interact with several medicines, including antihistamines, tricyclic antidepressants, other anticholinergic drugs, and sedatives — all of which may increase the risk of side effects such as drowsiness or dry mouth. Always tell your pharmacist about any medicines you are currently taking before starting Kwells. If you are managing other conditions and need related products, our pain relief collection may also be of interest for your travel kit.

How Should You Use Kwells Travel Sickness Tablets?

Kwells tablets are straightforward to use, but getting the timing right makes a real difference to how well they work. Always read the patient information leaflet before taking this medicine, and follow the steps below for best results.

What Is the Correct Dose of Kwells Travel Sickness Tablets?

The dose of Kwells is the same for adults and children aged 10 and over. It is important not to exceed the maximum daily dose, regardless of how long your journey lasts. The table below summarises the recommended dosing.

When Is the Best Time to Use Kwells Travel Sickness Tablets?

Timing is everything with Kwells. The tablets need to be taken before travel starts — ideally 20 to 30 minutes before you set off — so that the hyoscine hydrobromide has time to be absorbed and reach the brain before the conflicting sensory signals of motion begin. If you are catching an early morning ferry or coach, plan ahead the night before so you do not forget. Taking Kwells reactively, once nausea has already set in, is far less effective than using it preventatively.

How Long Can You Use Kwells Travel Sickness Tablets For?

Kwells are designed for short-term use during travel only. Each dose lasts approximately four to six hours, and you can take up to three tablets in any 24-hour period. They are not intended for continuous daily use over extended periods. If you find yourself needing motion sickness medication very regularly — for example, for a lengthy cruise or repeated long-haul travel — speak to your GP or pharmacist about whether a longer-acting option such as a hyoscine patch might be more appropriate for your needs.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

Work really well

What Are the Most Common Side Effects of Kwells Tablets?

Because hyoscine hydrobromide is an anticholinergic medicine, most of its side effects stem from the way it blocks certain nerve signals throughout the body — not just in the brain. These effects are generally mild and tend to resolve once the medicine wears off. That said, it is worth knowing what to expect before you travel.

  • Drowsiness or sedation
  • Dry mouth
  • Blurred vision
  • Dizziness
  • Headache

What Are the Less Common Side Effects of Kwells Tablets?

Some people experience side effects that are less frequent but still worth being aware of, particularly if you are elderly or taking other medicines that have anticholinergic properties. These effects are more likely at higher doses.

  • Difficulty urinating or urinary retention
  • Constipation
  • Increased heart rate (tachycardia)
  • Skin flushing or redness
  • Confusion or disorientation (particularly in older adults)
  • Restlessness or agitation
  • Skin rash or itching

What Are the Serious Side Effects of Kwells Tablets?

Serious side effects from Kwells are uncommon when the medicine is used as directed, but they can occur. You should stop taking Kwells immediately and seek urgent medical attention if you experience any of the following.

  • A fast, pounding, or irregular heartbeat
  • Severe difficulty passing urine
  • Sudden worsening of confusion or disorientation
  • Signs of an allergic reaction: swelling of the face, lips, tongue, or throat; difficulty breathing; or a widespread skin rash
  • Eye pain or sudden changes in vision (which could indicate raised eye pressure)

What Should You Do If You Experience Side Effects of Kwells?

For mild side effects such as a dry mouth or slight drowsiness, these usually resolve on their own as the medicine wears off. Staying hydrated and resting in a cool environment can help. Do not drive, cycle, or operate machinery if you feel drowsy after taking Kwells. If side effects are troublesome or do not improve, stop taking the tablets and speak to a pharmacist. You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Kwells Interact With Other Medicines?

Yes — Kwells can interact with a number of other medicines, and these interactions can increase the risk or severity of side effects. The most clinically significant interactions involve medicines that also have anticholinergic or sedative properties. Always tell your pharmacist about everything you are currently taking, including over-the-counter products and herbal remedies.

  • Alcohol: Significantly increases drowsiness — avoid during treatment.
  • Antihistamines (e.g. chlorphenamine, cetirizine): Combined anticholinergic effects may be enhanced.
  • Tricyclic antidepressants (e.g. amitriptyline): Increased risk of dry mouth, urinary retention, and confusion.
  • Sedatives or hypnotics: Additive sedation — use with caution.
  • Other anticholinergic medicines: Risk of cumulative anticholinergic toxicity.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
