About Kwells

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.

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 that are designed to dissolve and be absorbed from under the tongue, eg sublingual glyceryl trinitrate (GTN) tablets, become less effective. This is because the tablets do not dissolve properly in a dry mouth. To resolve this, drink a mouthful of water before taking sublingual tablets.

Other possible side effects include:

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

Cautions

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.

• Are over 60 years of age.
• Are under medical care, especially for heart, metabolic, gastrointestinal, kidney conditions, 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.
