What ALDACTONE is used for

What ALDACTONE does

ALDACTONE is used:
To treat essential hypertension (high blood pressure with an unknown cause)
To treat oedematous disorders (swelling with fluid), including congestive cardiac failure
For the diagnosis and treatment of primary aldosteronism (a hormone disorder causing fluid retention)
As add-on therapy in malignant hypertension (a very serious form of high blood pressure)
Where there is a low amount of potassium (a mineral) in the blood caused by another diuretic (fluid-removing medicine)
ALDACTONE improves the blood pressure lowering action of thiazide diuretics while at the same time reducing or preventing potassium loss due to these medicines.
For the prevention of low amounts of potassium in the blood in patients taking digitalis (a type of heart drug)
For the treatment of hirsutism (excess body hair in women)

How ALDACTONE works

ALDACTONE acts by working against a hormone called aldosterone. Too much aldosterone causes increased amounts of sodium (a mineral) and water to be retained by the kidneys, while too much potassium is removed from the body. ALDACTONE works against the effects of aldosterone.
ALDACTONE acts by removing excess fluid and by lowering blood pressure. It may be given alone or with other diuretics (fluid-removing medicines). It improves the effectiveness of other medicines used to lower blood pressure.
ALDACTONE also has a moderate ability to act against male sex hormones (anti-androgenic effect). Because of this, ALDACTONE is effective in the treatment of female hirsutism (excess body hair). It reduces hair growth, thickness and hair colour. Increased urine flow is unlikely to be a problem when ALDACTONE is used to treat hirsutism. This is because aldosterone levels are not normally high in patients with hirsutism.
The safety of ALDACTONE for the treatment of hirsutism in women of child-bearing age has not been established by specific studies.
Your doctor may recommend combined use with oral contraceptives to provide both regular menstrual cycles and adequate contraception.
Your doctor, however, may prescribe ALDACTONE for another purpose.
Ask your doctor if you have any questions about why ALDACTONE has been prescribed for you.
There is no evidence that ALDACTONE is addictive.

How to take ALDACTONE

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 box, ask your doctor or pharmacist for help.
Your doctor or pharmacist will tell you how many tablets you will need to take each day. This depends on your condition and whether or not you are taking any other medicines.

How much to take

Daily doses of ALDACTONE in adults can range from 25 mg to 400 mg. Depending on the dose and your condition, ALDACTONE may be taken once a day or divided into separate doses.
In the treatment of hirsutism (excess body hair) in females, your doctor may tell you to take ALDACTONE every day or in repeating cycles with a break in between.
Follow your doctor's instructions exactly regarding the dose you should take and how often you should take it.
Doses of ALDACTONE in children are measured according to body weight and will be calculated by your doctor.

If you forget to take it

If you forget to take ALDACTONE, do not try to make up for missed doses by taking more than one dose at a time.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much ALDACTONE.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
Keep telephone numbers for these places handy.
Overdose may cause nausea and vomiting. Sometimes, drowsiness, mental confusion, rash, diarrhoea or dehydration may occur.

While you are taking ALDACTONE

Things you must do

Take ALDACTONE exactly as your doctor has prescribed.
Tell all doctors, dentists and pharmacists who are treating you that you are taking ALDACTONE.
This is especially important if you are going to receive an anaesthetic agent while being treated with ALDACTONE.
If you are about to have any blood tests tell your doctor that you are taking ALDACTONE.
ALDACTONE may interfere with the results of some tests.
Tell your doctor if you're taking other types of medicines to treat high blood pressure.
Tell your doctor if you're taking medicines to prevent blood clots
Tell your doctor if you become pregnant while you are taking ALDACTONE.
If it is possible for you to become pregnant, you should use adequate contraception while you are taking ALDACTONE.
Examples of adequate contraception are oral contraceptives ("the Pill") or intra-uterine devices (IUDs).
Stop taking ALDACTONE if you become pregnant or you think you may be pregnant.
Go to your doctor regularly for a check-up.
Your doctor may do blood tests to check your sodium and potassium levels and see how your kidneys are working.
Your doctor may do the blood test weekly at the start of your treatment, monthly for the first 3 months of treatment then quarterly for a year, and then every 6 months when increasing your dose.
You may need to stop taking ALDACTONE if your blood is high in potassium or if your kidneys are not working properly.

Things you must not do

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 ALDACTONE, too much potassium can cause serious problems, such as disturbances to the heart rhythm.
Do not drive or operate machinery until you know how ALDACTONE affects you.
ALDACTONE may cause drowsiness or dizziness in some people and may affect alertness.
Do not give this medicine to anyone else even if their symptoms seem similar to yours.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking ALDACTONE.
Like other medicines, ALDACTONE can cause some side effects. If they occur, they are most likely to be minor and temporary. However, some may be serious and need medical attention.
ALDACTONE helps most people with essential hypertension, oedematous disorders, primary aldosteronism, malignant hypertension and hirsutism 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 treatment if you get some of the side effects.
