Patient Reviews: How Kwells Has Made a Difference

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.

You don't need a prescription for Kwells travel sickness tablets. Kwells tablets are available over-the-counter from pharmacies.

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.

Orders before 3pm on weekdays can be dispatched the same day, intended for a next-day delivery.

How does Kwells work?

Kwells travel sickness tablets 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 blocking 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?

You can swallow Kwells whole with a glass of water.

If you have difficulty swallowing, you can chew or suck Kwells tablets.

Kwells tablets can be taken with or without food.

When should I take Kwells?

Kwells can be taken in one of two ways:

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

You can take one Kwells tablet every 6 hours as required.

Do not take more than 3 Kwells tablets in any 24-hour period.

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 more Kwells tablets to make up for the forgotten dose.
