1. what aldactide is and what it is used for

Aldactide is a diuretic medicine (“water tablet”) used for the treatment of Congestive Heart Failure.

You may have gone to your doctor because of symptoms like swollen ankles and breathlessness. 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. This may lead to weakness. Your doctor has given you Aldactide 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 Aldactide.

You must talk to a doctor if you do not feel better or if you feel worse.

2.what you need to know before you take aldactide

Do not take Aldactide if:

• you are allergic to spironolactone, thiazide, diuretics or sulphonamides (a type of antibiotic) or any of the other ingredients of this medicine (listed in section 6)
• 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 have hypercalcaemia (raised blood calcium levels)
• you cannot pass urine
• you have severe kidney disease
• you are taking other potassium conserving diuretics or potassium supplements, which may induce hyperkalaemia

Warnings and precautions

Talk to your doctor or pharmacist before taking Aldactide if:

• you suffer from liver disease
• you are pregnant
• you have diabetes, gout, systemic lupus erythematosus (lupus), or high blood fats, " (such as high cholesterol)
• you are taking loop diuretics, glucocorticoids or adrenocorticotropic hormones (ACTH) as this may lead to profound diuresis and hypokalaemia (reduced blood potassium levels)
• you are taking other diuretics, which may cause hyponatraemia (reduced blood sodium levels)
• you have kidney problems
• you need your blood potassium levels to be monitored because you are taking other medicines which could cause you to lose too much body fluid
• you experience a decrease in vision or eye pain. These could be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or an increase of pressure in your eye and can happen within hours to a week of taking Aldactide. This can lead to permanent vision loss, if not treated. If you earlier have had a penicillin or sulfonamide allergy, you can be at higher risk of developing this
