Common side effects of Buscopan
These common side effects of Buscopan happen in more than 1 in 100 people. There are things you can do to help cope with them:
Dry mouth
Chew sugar-free gum or suck sugar-free sweets.
Some people with IBS find that chewing gum or sugar-free sweets make their IBS worse. If this happens, do not use gum or sweets. You may find cold unsweetened drinks or sucking on ice lollies or ice-cubes helps your dry mouth.
Constipation
Get more fibre into your diet, such as fresh fruit, vegetables and cereals, and drink plenty of water. Try to exercise more regularly, for example, by going for a daily walk or run.
Blurred vision
Do not drive, cycle or use tools or machinery 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 does not return to normal.
Speak to a doctor or pharmacist if the advice on how to cope does not help and a side effect is still bothering you or does not go away.
