1. What Aldactone is and what it is used for
Aldactone contains the active substance spironolactone. Aldactone belongs to a group of medicines called ‘diuretics’ - you may know these as ‘water’ tablets. You may have gone to your doctor because you had swollen ankles or were short of breath. This can happen when your heart’s pumping action has become weak because of too much fluid in your body. This is called ‘congestive heart failure’. Pushing extra fluid around your body means your heart has to work harder. Your doctor has given you Aldactone to help you lose the extra fluid from your body. This will mean your heart has to do less work. You lose the extra fluid as urine, so you may need to go to the toilet more often while you are taking Aldactone.
You can also take Aldactone for the following illnesses:
• ‘Nephrotic syndrome’ - a kidney disorder that causes too much fluid in your body
• ‘Ascites’ - too much fluid in your abdomen and ‘oedema’ -accumulation of fluid beneath skin or in one or more cavities of the body that produces swelling, for example caused by cirrhosis of the liver
• ‘Malignant ascites’- fluid containing cancer cells that collect
in the abdomen
• ‘Primary aldosteronism’ - extra fluid in your body caused by too much of a hormone called ‘aldosterone’.
If you have these illnesses, Aldactone will help your body to get
rid of the extra fluid. You must talk to a doctor if you do not feel better or if you feel worse.
Children should only be treated under guidance of a paediatric specialist.
Do not take Aldactone if:
• you are allergic to spironolactone or any of the other ingredients of this medicine (listed in section 6)
• you cannot pass urine
• you have severe kidney disease
• you have Addison’s disease; (a hormone deficiency characterised by extreme weakness, loss of weight and low blood pressure)
• you have hyperkalaemia (raised blood potassium levels)
• you are breast-feeding
• you are taking water tablets (potassium sparing diuretics) or any potassium supplements
• you are taking eplerenone (a medicine for high blood pressure). Children with moderate to severe kidney disease must not take Aldactone.
Warnings and precautions
Talk to your doctor or pharmacist before taking Aldactone if:
• you suffer from kidney disease especially children with hypertension or liver disease. Your doctor will routinely assess you particularly if you are elderly
• you have difficulty passing urine
• you have a disease that can result in electrolyte balance disturbance in your blood such as potassium or sodium
• you have severe heart failure
• you are pregnant
If you experience reduced kidney function or kidney failure you may have severe increases in the levels of potassium in your blood. This can affect the way your heart functions and in extreme cases this can be fatal.
Concomitant administration of Aldactone with certain medicines, potassium supplements and food rich in potassium may lead to severe hyperkalaemia (increased potassium blood level). The symptoms of severe hyperkalaemia might include muscle cramps, irregular heart rhythm, diarrhoea, nausea, dizziness or headache. Other medicines and Aldactone Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without prescription. Your doctor may wish to alter your dose of Aldactone if you are taking any of the following:
• digoxin or carbenoxolone
• medicines for high blood pressure including angiotensinconverting enzyme (ACE) inhibitors
• other diuretics
• non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, indomethacin, mefenamic acid or ibuprofen
• potassium supplements
• heparin or low molecular weight heparin (medicines used to prevent blood clots)
• medicines known to cause hyperkalaemia (raised blood potassium levels)
• trimethoprim and trimethoprim-sulfamethoxazole Aldactone reduces your responsiveness to noradrenaline. If you are going to have an operation where you will be given an anaesthetic, tell the doctor in charge that you are taking Aldactone.

Your doctor will start you on a low starting dose and gradually increase the dosage as needed to obtain the desired effect.

Your doctor will work out the number of tablets that you should give.
If you take more Aldactone than you should If you accidentally take too many tablets, contact your doctor or nearest hospital accident and emergency department immediately. The symptoms of an overdose are feeling drowsy, dizzy, feeling dehydrated and you may feel confused. You may also feel or be sick, suffer from diarrhoea and may have skin rashes that will appear as flat red areas of skin with overlapping small raised bumps. Changes in your blood sodium and potassium levels may leave you feeling weak and suffering from tingling, prickling or numbness of the skin and/or muscle spasms but these symptoms are unlikely to be associated with severe overdosage.
