What are Kwells?

Kwells is a fast and effective treatment for motion sickness. It contains 300mcg of the active ingredient hyoscine hydrobromide, also known as scopolamine.

Kwells travel sickness tablets are easy to take and can be swallowed whole, chewed or sucked. The tablets melt in your mouth and are absorbed quickly into your bloodstream, making them work fast.

You can take Kwells 20 to 30 minutes before travelling or when your symptoms start.

If you can't get to your local pharmacy, you can buy Kwells online from Prescription Doctor's trusted online UK pharmacy. We make it fast and convenient to buy travel sickness tablets online and have them delivered to your door.

What is motion sickness?

Motion sickness is the feeling of nausea and general malaise which may occur when travelling in a car, boat or plane.

The feeling occurs due to conflicting signals between the vestibular system and the brain. The vestibular system is the part of the body which senses balance, orientation and motion.

When the vestibular system detects motion, but no motion is perceived by the eyes, the conflicting signals trigger the vomit centre in the brain. Likewise, if motion is perceived by the eyes but not sensed by the rest of the body, such as with VR headsets, the same result can occur.

Symptoms of motion sickness include:

  • Cold sweats
  • General feeling of illness
  • Nausea
  • Paling of the skin
  • Stomach ache
  • Vomiting

What natural methods can I try to prevent motion sickness?

If you are susceptible to motion sickness, there are some things you can do to minimise your risk of experiencing motion sickness.

Before taking a journey, avoid any foods which may exacerbate your symptoms such as alcoholic beverages, spicy food or heavy meals.

When travelling by car, try sitting in the front or in the middle of the car. Try to look ahead at the horizon and avoid using electronic devices or reading books while travelling. If you take a particularly long car journey, remember to take frequent breaks to stretch your legs and drink some water.

When travelling by boat, try sitting in the middle of the boat whenever possible. You can also stand on the deck and look out at the horizon. Limit your time looking at books, screens, or the waves when travelling by boat.

When travelling by aircraft, sitting by the window rather than the aisle can reduce your feeling of sickness. Especially if your seat is situated at the front of the aircraft or over the wings. You can suck on hard-boiled sweets during take-off and landing to relieve the feeling of pressure in your ears.

Ginger and peppermint sweets and chewing gum have been known to reduce the feeling of nausea and sickness in some people.

If your motion sickness is particularly serious, Kwells is an effective treatment to help improve your symptoms.

How does Kwells work?

Kwells contain 300mcg (0.3mg) of a muscarinic agonist called hyoscine hydrobromide (Scopolamine).

The active ingredient blocks nerve signals between the vestibular system and vomit centre of the brain. By preventing these signals, the brain is unaware of the conflicting messages between the eyes and the vestibular system, which prevents the vomit centre from being triggered.

Hyoscine hydrobromide can settle contractions in the walls of the stomach and decrease the production of saliva. 

When taken before travelling in a vehicle, Kwells is effective at preventing motion sickness from developing, giving you peace of mind when you travel.

How long does Kwells travel sickness tablets take to work?

Kwells travel sickness tablets start working in as little as 30 minutes.

How long do the effects of Kwells last?

Kwells can provide relief from travel sickness for up to 4 hours.

How do I take Kwells?

Kwells can be taken in two ways:

  • Take one tablet half an hour before you travel
  • Take one tablet as soon as you notice symptoms of motion sickness

Like other tablets, Kwells can be swallowed whole with a glass of water, but you may also chew or suck the tablets if you find it difficult to swallow tablets.

Kwells tablets can be taken with or without food.

What should I do if I forget to take Kwells before travelling?

If you forget to take Kwells before travelling, take it as soon as you remember.

Do not take moe Kwells tablets to make up for the forgotten dose.

What should I do if I take too many Kwells Tablets?

If you take more Kwells tablets than you should, symptoms of an overdose may occur.

Symptoms of an overdose of Kwells include:

  • Blurred vision
  • Difficulty urinating
  • Fast or irregular heartbeat
  • Hallucinations
  • Sensitivity to light

If you experience any of the above symptoms, seek immediate medical attention or go straight to your nearest accident and emergency department. Take the medicine packaging with you, even if it's empty, so that the doctors know what and how much of it you took.
