What does it do?

Hyoscine hydrobromide patches are used to treat and prevent nausea, vomiting and dizziness. They are also sometimes used for other conditions.

Before you start

  • Tell your doctor if you have liver, bowel, prostate or bladder problems, or if you have angle-closure glaucoma.
  • Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you use it?

Apply the patch to the skin behind your ear. It will start to work in 5 to 6 hours and last up to 3 days.
Remove the patch when no longer required, or, if you need to use the patch for longer than 3 days, remove it and apply a new one behind your other ear.
Do not cut the patch.
Wash your hands after handling the patch to prevent hyoscine hydrobromide accidentally getting into your eyes.

What if you forget a dose?

If you forget to change the patch, remove the old patch and apply a new one as soon as possible.

Can you take other medicines?

Some medicines available without a prescription may react with hyoscine hydrobromide including:

  • some antihistamines (may be in anti-allergy, anti-nausea and cough/cold medicines)
  • other medicines that may cause drowsiness (e.g. pain-killers, anti-nausea and cough/cold medicines – ask your pharmacist)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. valerian) or recreational drugs.
