Consumer Medicine Information
This leaflet answers some common questions about Spiractin.
It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking Spiractin against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, talk to your doctor or pharmacist.
Keep this leaflet with your medicine. You may need to read it again.
Spiractin is used:
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that Spiractin is addictive.
In fluid build-up and high blood pressure
Spiractin is a fluid tablet or diuretic. It helps reduce the amount of excess fluid in the body by increasing the amount of urine produced. This also helps to lower blood pressure.
In hyperaldosteronism and low potassium levels in the blood
In hyperaldosteronism, the adrenal glands produce too much of a hormone called aldosterone. Spiractin works by stopping the effects of aldosterone.
By stopping the effects of aldosterone, Spiractin also helps to maintain normal levels of potassium in the blood by retaining potassium in the body.
In women with excess hair
All women produce small amounts of the male sex hormone, testosterone. Women with excess facial or body hair tend to be especially sensitive to the action of testosterone on hair growth. Spiractin reduces the growth of hair by stopping the effects of testosterone.

Follow all directions given to you by your doctor and pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the bottle, ask your doctor or pharmacist for help.
Your doctor will tell you how many tablets you need to take each day. This depends on your condition and whether or not you are taking other medicines.
Swallow the tablets with a glass of water.
Depending on the dose and your condition, Spiractin may be taken once a day or divided into separate doses.
Take Spiractin with or immediately after food.
Continue taking your medicine for as long as your doctor tell you to.
The length of treatment will depend on your condition. Spiractin is usually taken long term.
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 take a double dose to make up for the dose that you missed.
If you are not sure what to do, ask your doctor or pharmacist.
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital if you think you or anyone else may have taken too much Spiractin. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much Spiractin, you may feel drowsy, weak, confused or sick, vomit, have diarrhoea or pins and needles of the hands or feet.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Spiractin.
Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine. This is especially important if you are going to receive an anaesthetic agent while being treated with Spiractin.
If you become pregnant while taking this medicine, tell your doctor immediately. If it is possible for you to become pregnant, you should use adequate contraception while you are taking Spiractin. Examples of adequate contraception are oral contraceptives ("the Pill") or intra-uterine devices (IUDs). Stop taking Spiractin if you become pregnant or you think you may be pregnant.
If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.
Keep all of your doctor's appointments so that your progress can be checked. Your doctor may ask you to have blood tests to check your sodium and potassium levels and see how your kidneys are working.
Do not take Spiractin 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.
Do not stop taking your medicine or lower the dose without checking with your doctor.
Do not take potassium supplements or use salt substitutes that contain potassium.
Do not consume a diet rich in potassium. Dried fruit, bananas and oranges are some foods that contain high amounts of potassium. Consuming some of these foods is usually safe but do not consume excessive amounts.
If you are taking Spiractin, too much potassium can cause serious problems, such as disturbances to the heart rhythm.
Be careful driving or operating machinery until you know how Spiractin affects you. This medicine may cause drowsiness or dizziness in some people. If you have any of these, do not drive, operate machinery or do anything else that could be dangerous.
