Cautions with other medicines
Some medicines and Buscopan can interact with each other and increase the chances of you having side effects.
Do not take Buscopan at the same time as some motion sickness medicines, such as domperidone or metoclopramide.
This is because they can stop each other from working. Metoclopramide and domperidone increase the movement of the gut, whereas Buscopan reduces it.
Some medicines increase the risk of side effects if you take them at the same time as Buscopan, including:
- medicines for allergies, such as antihistamines
- some medicines for depression, such as amitriptyline
- some medicines for mental health problems like schizophrenia or bipolar disorder, such as clozapine or chlorpromazine
- amantadine, a medicine for Parkinson's disease
- quinidine or disopyramide (heart medicines)
- some inhaled asthma medicines, including salbutamol, ipratropium and tiotropium
Do not take Buscopan together with other irritable bowel syndrome (IBS) remedies, as they work in the same way. You're unlikely to get extra relief for your symptoms, and it may cause more side effects. Take only 1 IBS remedy, unless your doctor tells you to take more than 1.
Mixing Buscopan with herbal remedies and supplements
There's not enough information to say that complementary medicines and herbal remedies are safe to take with Buscopan.
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.
Important: Medicine safety
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.
