What are Kwells?

Kwells are tablets which manage travel sickness. Motion sickness occurs when the brain is receiving conflicting messages about the body's spatial awareness, causing nausea and vomiting.

How do Kwells work?

Kwells is a type of medicine called an antimuscarinic. It stops the inner ear from sending messages to the brain that the body is moving. These messages conflict with what the eyes tell the brain; that the body is stationary. These messages are received by the vomiting centre within the brain, in turn causing sickness. The medicine also prevents the stomach from receiving triggers from the vomiting centre in the brain. 

How long do Kwells take to work?

Kwells tablets will usually start to work 15 minutes after taking them. 

How effective are Kwells?

Hyoscine is the active ingredient contained in Kwells which is the most effective treatment for travel sickness.

Are Kwells gluten free?

How to avoid travel sickness

There are several things you can do to reduce travel sickness or prevent it from happening. Reducing the amount of motion by sitting in the front seat of the car or the middle of the ferry, getting fresh air and keeping your gaze fixed ahead of you can help. Avoid reading or looking at moving objects, focus on steadying your breath and close your eyes and try consuming ginger which settles the stomach.
