Common side effects
These side effects happen in more than 1 in 100 people.

- fast heart rate
Serious side effects
It happens rarely, but some people may have a serious side effect when taking Buscopan.
Stop taking Buscopan and call a doctor straight away if you:

Serious allergic reaction
In rare cases, it’s possible to have a serious allergic reaction (anaphylaxis) to Buscopan.
What to do about:
- dry mouth – chew sugar-free gum or suck sugar-free sweets
- constipation – eat more high-fibre foods, such as fresh fruit and vegetables and cereals, and drink plenty of water. Try to exercise more regularly, for example, by going for a daily walk or run. If this doesn’t help, talk to your pharmacist or doctor.
- blurred vision – do not drive until you can see clearly again. Do not take your next dose of Buscopan if your vision is still blurry. Speak to your doctor or pharmacist if your vision hasn’t returned to normal a day after taking your last dose.
- fast heart rate – if this occurs regularly after taking Buscopan, try to take your medicine at a time when you can sit or lie down when the symptoms are worst.

You may need to change to a different type of medicine.
Buscopan isn’t usually recommended during pregnancy and while breastfeeding.
Tiny amounts of Buscopan may get into breast milk, but it’s not known if it harms the baby. There’s a small risk that Buscopan may reduce your milk production.

Do not take Buscopan at the same time as some travel sickness medicines, such as domperidone and metoclopramide.
This is because they can cancel each other out and 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 (taken for Parkinson’s disease)
- quinidine or disopyramide (heart medicines)
- some inhaled asthma medicines, including salbutamol, ipratropium, tiotropium
It’s usually best not to take Buscopan together with other 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 advises otherwise.
