Cautions with other medicines
Hyoscine hydrobromide can be affected by some medicines and affect the way other medicines work. Taking it with other medicines can also increase your risk of side effects.
Do not take hyoscine hydrobromide if you're taking medicines such as domperidone or metoclopramide, which are used to increase the movement of food through your gut. Taking these with hyoscine hydrobromide can stop it working properly.
Tell your pharmacist or doctor before taking hyoscine hydrobromide if you're taking any of these medicines:
- amantadine, a medicine for Parkinson's disease
- quinidine or disopyramide, heart medicines
- allergy medicines, such as antihistamines
- some medicines for depression, such as amitriptyline
- some inhaled asthma medicines, including ipratropium or tiotropium
- medicines for mental health problems, such as chlorpromazine or clozapine
Mixing hyoscine hydrobromide with herbal remedies and supplements
There might be a problem taking some herbal remedies and supplements alongside hyoscine hydrobromide, especially ones that cause side effects such as sleepiness, a dry mouth or making it difficult to pee.
Ask a pharmacist for advice.
There's not enough information to say whether other complementary medicines, herbal remedies and supplements are safe to take with hyoscine hydrobromide. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
