  1. Contents of the pack and further information

1. What is Aldoleo and what is it used for

Aldoleo contains two active substances: chlorthalidone and spironolactone. Chlorthalidone and spironolactone belong to a group of medicines called diuretics. They are medicines that increase the elimination of fluids from the body.

Aldoleo is used to reduce swelling caused by fluid accumulation (edema) due to certain kidney, liver, or heart diseases, and to reduce high blood pressure (hypertension).

Children should only be treated under the supervision of a pediatrician.

2. What you need to know before you take Aldoleo

Do not take Aldoleo:

  • If you are allergic to spironolactone or chlorthalidone or any of the other ingredients of this medicine (listed in section 6).
  • If you are allergic to a group of medicines called thiazides or to other sulphonamide-derived drugs.
  • If you have a disease called Addison's disease, which causes damage to the adrenal cortex, leading to a hormonal deficiency.
  • If you have high potassium levels in your blood (hyperkalemia).
  • If you are taking potassium supplements or other medicines used to treat high blood pressure or heart problems (heart failure): potassium-sparing diuretics (including eplerenone) or a combination of an angiotensin-converting enzyme inhibitor (ACE) and an angiotensin receptor antagonist (ARA).
  • If you have high calcium levels in your blood (hypercalcemia).
  • If your kidneys have severe problems functioning (severe renal insufficiency or acute renal failure with no urine production (anuria)).
  • If you are a child suffering from moderate to severe kidney disease (renal insufficiency).
  • If your liver has severe problems functioning (liver insufficiency).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Aldoleo.

Inform your doctor if you suffer from any of the following conditions:

  • if you have liver or kidney problems,
  • if you experience a decrease in vision or eye pain, they could be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or increased pressure in the eye, and they can occur within a few hours to a week after taking Aldoleo,
  • if you have a disease called lupus erythematosus,
  • if you are diabetic,
  • if you are going to undergo surgery,
  • if you are taking other diuretics,
  • if you have high uric acid levels (gout),
  • if you have high cholesterol and triglyceride levels,
  • if you have had allergies or bronchial asthma.

The concomitant administration of Aldoleo with certain medicines, potassium supplements, and foods rich in potassium can cause severe hyperkalemia (increased potassium levels in the blood). The symptoms of severe hyperkalemia may include muscle cramps, irregular heartbeat, diarrhea, nausea, dizziness, or headache.

Children and adolescents

It is recommended that they do not take this medicine.

Taking Aldoleo with other medicines

  • Other medicines for treating high blood pressure (antihypertensives).
  • Medicines that can alter the balance of electrolytes in the body (e.g., ammonium chloride, cholestyramine, trimethoprim/sulfamethoxazole (co-trimoxazole)).
