Kwells 0.3mg tablets are used for the fast and effective prevention and control of travel sickness. Travel sickness happens when the brain receives mixed messages. Visual messages from the eyes inform the brain that the immediate surrounds are stationary, but a delicate balancing organ in the ear tells the brain that you are moving. This conflicting information triggers the nausea we associate with travel sickness.

The active substance in Kwells tablets is Hyoscine Hydrobromide. Hyoscine Hydrobromide temporarily reduces the effect of movement on the balance organs of the inner ear and the nerves responsible for nausea.

Because Kwells tablets melt in the mouth, absorption into the bloodstream is very rapid and they can be taken up to 20 - 30 minutes before travelling or at the onset of sickness.


If Kwells have been prescribed for you by your doctor, follow instructions they may have given you. If you purchase the product without a prescription, then follow these directions closely.

The tablets can be sucked, chewed or swallowed.  They have a score line so they can be halved if necessary. The tablets can be taken up to 30 minutes before travelling to prevent travel sickness or at the onset of nausea.


Take one tablet every 6 hours, as required.  Do not take this medicine more than 3 times in 24 hours.


Consult your doctor or pharmacist before taking Kwells tablets.

Children over 10 years:

Give your child half or one tablet every 6 hours, as required.

  • Do not give your child this medicine more than 3 times in 24 hours.

Kwells tablets should not be given to children under 10 years of age.
