Common side effects of solifenacin
These common side effects of solifenacin happen in more than 1 in 100 people. They're usually mild and do not last long. There are things you can do to help cope with them:
Dry mouth
Try chewing sugar-free gum or sucking sugar-free sweets.
Having a dry mouth can cause tooth decay or a fungal infection. It also might stop medicine that you put under your tongue from dissolving properly, such as medicine for angina.
Headache
Make sure you rest and drink plenty of fluids. Avoid alcohol. Ask your pharmacist to recommend a painkiller. Talk to your doctor if your headache is severe or does not go away.
Feeling sick (nausea)
Try taking your tablets with food. It may also help if you avoid rich or spicy food.
Constipation
Get more fibre into your diet, 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.
Bloating and indigestion
Eat less foods that cause wind, like lentils, peas, beans and onions. It might also help to eat smaller and more frequent meals, eat and drink slowly, and exercise regularly. Ask your pharmacist about remedies you can buy to help with indigestion.
Stomach pain
Try to rest and relax. It can help to eat and drink slowly and have smaller and more frequent meals. Putting a heat pad or a covered hot water bottle on your stomach may also help.
If you're in a lot of pain or your pain does not go away, speak to your doctor.
Blurred vision
Do not drive, ride a bike or use tools or machinery until you can see clearly again. Do not take your next dose of solifenacin if your vision is still blurred. Speak to your doctor or pharmacist if your vision does not return to normal.
Talk to your 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.
