What DETRUSITOL is used for
DETRUSITOL is used to treat symptoms of an overactive bladder, for example urinary frequency, urgency or incontinence.
DETRUSITOL belongs to a group of medicines called antispasmodics. It helps to control the release of urine by reducing spasm, and relaxing the smooth muscle of the bladder wall.
It also increases the storage volume of the bladder, and can act on the brain to delay the desire to urinate.
Ask your doctor if you have any questions about why DETRUSITOL has been prescribed for you.
This medicine is not addictive.
This medicine is available only with a doctor's prescription.

How to take DETRUSITOL
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
How much to take
The usual dose is 1mg or 2mg twice daily. Your doctor will prescribe the dose that is right for you.
How to take it
Swallow the tablets whole with a full glass of water.
When to take it
Take your medicine at about the same time each day. Taking DETRUSITOL at the same time each day will have the best effect. It will also help you remember when to take it.
It does not matter if you take DETRUSITOL before or after food.
How long to take it
Continue taking your medicine for as long as your doctor tells you. This medicine helps to control your condition, but does not cure it. It is important to keep taking your medicine even if you feel well.
Your doctor should re-assess your condition at regular intervals, for example after 6 months, to determine how long you need to keep taking DETRUSITOL for.
If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not try to make up for missed doses by taking more than one dose at a time. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poison Information Centre – the telephone number in Australia is 131 126 and in New Zealand is 0800 POISON or 0800 764 766 – or go to the Accident and Emergency (Casualty) Department at your nearest hospital if you think you or anyone else may have taken too much DETRUSITOL. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
The symptoms of taking too much DETRUSITOL may include shortness of breath, fits, fast heart beat, inability to pass urine, dilated pupils, feeling excited or hallucinations.
While you are using DETRUSITOL
Things you must do
If symptoms of your overactive bladder do not improve, or if they become worse, tell your doctor.
If you are about to start taking any new medicine, remind your doctor and
pharmacist that you are taking DETRUSITOL.
If you become pregnant while taking DETRUSITOL, tell your doctor.
Tell all doctors, dentists, and pharmacists who treat you that you are taking DETRUSITOL.
If you are going to have surgery, tell the surgeon or anaesthetist that you are taking DETRUSITOL. It may affect other medicines used during surgery.
Always discuss with your doctor any problems or difficulties during or after taking DETRUSITOL.
Things you must not do
Do not take DETRUSITOL to treat any other complaints unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you or their symptoms seem similar to yours.
Do not stop taking your medicine or lower the dosage unless your doctor tells you to, even if you are feeling better.
Things to be careful of
Be careful driving or operating machinery until you know how DETRUSITOL affects you. This medicine may cause dizziness and blurred vision in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
Be careful when drinking alcohol while you are taking this medicine. If you drink alcohol, dizziness may be worse.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking DETRUSITOL. This medicine helps most people with an overactive bladder, but it may have unwanted side effects in a few people. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.
Do not be alarmed by the following lists of possible side effects. You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor or pharmacist if you notice any of the following and they worry you:
- Dry mouth
- Constipation, stomach pain or diarrhoea
- Dry eyes
- Swollen ankles
Tell your doctor immediately if you notice any of the following:
- Swelling of the face, lips, mouth, tongue or throat which may cause difficulty in swallowing or breathing
- Dizziness or confusion
- Fast heartbeat or palpitations
- Shortness of breath and swelling of the feet or legs
- Blurred vision
- Difficulty or pain in urinating (passing water)
- Hallucinations (seeing, hearing or feeling things that are not really there)
Tell your doctor or pharmacist if you notice anything that is making you feel unwell. Other side effects not listed above may also occur in some people.
After using DETRUSITOL
Keep your tablets in the blister until it is time to take them.
If you take the tablets out of the blister they may not keep well.
Keep your tablets in a cool dry place where the temperature stays below 25° Celsius.
Do not store DETRUSITOL or any other medicine in the bathroom or near a sink. Do not leave it on a windowsill or in the car. Heat and dampness can destroy some medicines.
Keep DETRUSITOL where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
