About Kwells travel sickness tablets

Kwells tablets are for the prevention of travel sickness. Kwells tablets can be taken up to 20-30 minutes before travelling to prevent travel sickness, or at the onset of nausea.

Tablets may be sucked, chewed, or swallowed. Adults should take 1 tablet every 6 hours, as required. Do not take more than 3 times in 24 hours. Elderly patients should consult their regular doctor before taking Kwells tablets as they may be at more risk from side effects, especially dizziness.

Separate dosage instructions for children over 10 years (Dr Fox does not supply treatment for under 18s).

Side effects

As with any medicine, there are potential side effects. The most commonly reported side effect is a dryness of the mouth, although this does not last long.

If you experience a dry mouth as a side effect of this medicine you may find that medicines designed to dissolve and be absorbed from the tongue, e.g. Maxalt melts for migraine, do not dissolve properly in a dry mouth. To resolve this, drink a mouthful of water before taking melt in the mouth tablets.

Other possible side effects include:

  • Sleepiness.
  • Dizziness.
  • Blurred vision or other visual disturbance.
  • Changes in size of pupils.
  • Decreased sweating.


Do not take if suffering from:

  • Glaucoma.
  • Paralytic ileus (intestinal nerves/muscles impairing digestive movement).
  • Pyloric stenosis (narrowing of passage between stomach and small bowel).
  • Myasthenia gravis (rare long-term autoimmune condition).
  • Enlarged prostate gland.
  • Allergic to hyoscine hydrobromide.

Kwells tablets may make you feel sleepy. If this happens do not drive or use tools or machines. Do not drink alcohol.

Do not take Kwells tablets if you are pregnant or breastfeeding unless recommended by your doctor.

Before taking Kwells tablets, you should consult your doctor if you:

  • Are under medical care, especially for heart, metabolic, gastrointestinal, kidney conditions, liver or bladder obstruction.
  • Have ulcerative colitis or a known bowel obstruction.
  • Have diarrhoea or fever.
  • Have Down's Syndrome.
  • Suffer from seizure or fits.
  • You are pregnant or breastfeeding.
  • If you have ever had glaucoma.
  • If you have reacted to hyoscine or other anti-sickness medications in the past.

Please note the patient information leaflet suggests seeing your doctor if you are over 60 years of age. If you are fit and well and over 60 there should be no problem taking Kwells. If you take other medications or have other health issues and are over 60, then Dr Fox suggests consulting your GP before using Kwells. If you experience side effects, especially dizziness, then stop the tablets.

Kwells are not suitable for children less than 10 years old.

Other medications

If you are taking some other medicines, you may still be able to use Kwells, but there are some medication interactions with Kwells. Please check and consult your regular doctor if advised.

Kwells 0.3mg hyoscine

Thorpe Park had me in a mess with motion sickness after one lame ride. I was almost comatose, it ruined the day for me but more importantly it ruined it for my girlfriend who loves Thorpe. Back the second day to make amends for the first, this time it took 3 rides to wreck me and actually vomit. I was determined to win so booked another trip with my girl back to the park, she was not confident!! I researched prescription strength anti sickness drugs which I was told for motion sickness are the same as the over the counter products. I read up on Kwells and put my faith in them. At Thorpe I went on everything and not a hint of motion sickness or side effects, I just felt totally normal!! Thoroughly recommend them!!
