Side effects of tolterodine

These common side effects of tolterodine happen in more than 1 in 100 people. There are things you can do to help cope with them:

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.

Make sure you rest and drink plenty of fluids. Avoid drinking alcohol. Ask your pharmacist to recommend a painkiller.

Talk to your doctor if your headache is severe or does not go away.

Do not drive, cycle, use tools, or operate machinery. Avoid drinking alcohol, as this may make your symptoms worse.

Drink lots of fluids, such as water or squash, to avoid dehydration. Signs of dehydration include peeing less than usual or having dark, strong-smelling pee. Do not take any other medicines to treat diarrhoea without speaking to a pharmacist or doctor.

If you take the combined contraceptive pill or progestogen-only pill and you have severe, watery diarrhoea or any diarrhoea that lasts for more than 24 hours, your contraception may not protect you from pregnancy. Look on the pill packet to find out what to do.

Speak to a pharmacist or doctor if diarrhoea lasts more than 1 or 2 days.

Try small frequent sips of water to avoid dehydration. Signs of dehydration include peeing less than usual or having dark, strong-smelling pee.

If you take the combined pill or progestogen-only pill and you're being sick, your contraception may not protect you from pregnancy. Check the pill packet for advice.

Speak to a pharmacist or doctor if you're being sick for more than 1 to 2 days.

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 trapped wind.

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 sudden severe pain, speak to your pharmacist or doctor.

Ask your pharmacist or optician to recommend some eye drops. If you wear contact lenses and these become uncomfortable, you might want to wear glasses instead while you're taking tolterodine.

Do not drive or ride a bike until you can see clearly again. Do not take your next dose of tolterodine. Speak to your doctor or pharmacist if your blurred vision does not go away.

Try to relax when you pee. Do not try to force the flow of pee. If it does not happen, try again later.

Talk to a doctor urgently if you cannot pee at all.

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.
