Scopoderm travel sickness patches contain a substance called hyoscine hydrobromide, which is one of the most widely used medications to treat travel sickness.
Hyoscine is absorbed through your skin via the self adhesive Scopoderm patch. Each patch contains 1.5mg of hyoscine and can be kept on for up to three days. It must be removed after 3 days and replaced if required.
What does it do?
The hyoscine works by reducing the conflict in your brain, which can happen while travelling. You begin to feel travel sick when there is a conflict between what your inner ear vestibular balance mechanism can sense and what your eyes can see.
Hyoscine blocks receptors called muscarinic (or cholinergic) in the vomiting centre from receiving messages from the vestibular system. This prevents the internal confusion, which causes the feeling of nausea.
How to use Scopoderm patches
This medicine works best before you start to feel ill, so it's recommended that you put on a patch 5 to 6 hours before travel. However, you can also use the patch during travel to help reduce nausea.
To ensure that you put on the patch correctly, follow these steps:
• Remove the patch from its seal and peel off the clear, hexagonal plastic backing. Hold the patch by its edge and be careful to avoid touching the sticky side.
• To put the patch on, find a dry, hairless area of skin behind your ear and press the silver-colored sticky side in place. Hold the patch there and count slowly to ten.
• Next, wash your hands thoroughly.
• When you remove the patch, wash your hands thoroughly afterwards, as well as washing the area of skin where the patch has been.
If the patch comes off accidentally during your journey, throw away the patch, wash the area, as advised above, and put a new patch on behind the other ear.
Each patch lasts for up to 3 days (72 hours). You can use Scopoderm patches for longer journeys - just take the patch off after 3 days and put a new one behind the other ear.
Cautions when using Scopoderm patches
• It's important to always wash your hands after inserting or removing a Scopoderm patch. You should also try to avoid touching the patch whilst it's on. This is because, if you touch your eyes with hyoscine on your fingers, the substance can temporarily blur your vision.
• Also, do not take other anti-sickness medicines whilst using Scopoderm patches.
• Provided that you have applied the patch properly, you can swim, bathe or shower with little risk of it coming off. However, it is best not to stay in the water too long.
• Do not cut the patches in an attempt to reduce the dosage. This may release a much larger dose in a short time period.
• Side effects of Scopoderm patches
• 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 under the tongue, e.g. 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.
• Redness, itching, or irritation of the skin where a patch has been.
• Changes in size of pupils.
• Decreased sweating.
If any of these effects are severe, or if you experience any other side effects, take the patch off and consult a doctor. Also seek medical assistance if any side effect lasts for over 24 hours, after removing the patch. However, it is rare for the symptoms to persist this long.
Due to the potential side effect of drowsiness, you must not drive or operate machinery whilst wearing a Scopoderm patch.
When not to use Scopoderm patches
• Serious gastrointestinal, kidney disease, or heart disease.
• Epilepsy
• Pregnancy or breastfeeding.
• Glaucoma.
• Have a history of bladder or bowel obstruction.
• If you've had a bad reaction to hyoscine, or other anti-sickness medication in the past.
• Ulcerative colitis.
• Diarrhea or fever.
• Down's Syndrome
If you are aged over 60 and are not fit and well, you may be more likely to experience dizziness with Scopoderm. Remove the patch and stop using Scopoderm if this happens.
