1. What is Spironol and what is it used for

Spironol contains the active substance spironolactone. Spironol belongs to a group of medicines called diuretics, also known as water tablets.
The reason for the patient's visit to the doctor may be swelling of the ankles or shortness of breath. These symptoms may occur if the heart's pumping function weakens due to too much fluid in the body. This is called congestive heart failure.
The need to pump excess fluid throughout the body means that the heart has to work harder. The doctor prescribes Spironol to the patient to get rid of excess fluid from the body. As a result, the heart will be able to work less hard.
Excess fluids are removed in the urine, so during Spironol treatment, it may be necessary to use the toilet more often.
Spironol may also be used in the following conditions:

• Nephrotic syndrome - a kidney disorder that causes excess fluid in the body.
• Ascites - excess fluid in the abdominal cavity and edema - fluid accumulation under the skin or in at least one body cavity (causing swelling), for example, due to liver cirrhosis.
• Ascites caused by malignant tumors - excess fluid due to the accumulation of cancer cells in the abdominal cavity.
• Primary hyperaldosteronism - excess fluid in the body due to too high a concentration of a hormone called aldosterone.
• Hypertension - as an additional medicine in patients who do not respond sufficiently to other antihypertensive medicines.

If the patient has the above conditions, Spironol will help get rid of excess fluid from the body.
If, after taking Spironol, the patient does not feel better or feels worse, they should consult a doctor.
Children should only be treated under the supervision of a pediatrician.

2. Important information before taking Spironol

When not to take Spironol:

• if the patient is allergic to spironolactone or any of the other ingredients of this medicine (listed in section 6);
• if the patient has Addison's disease (a deficiency of certain hormones, characterized by extreme weakness, weight loss, and low blood pressure);
• if the patient has hyperkalemia (elevated potassium levels in the blood);
• if the patient is unable to urinate (anuria);
• if the patient has severe kidney disease;
• if the patient is breastfeeding;
• if the patient is taking potassium-sparing diuretics (potassium-sparing diuretics) or any other medicines to supplement potassium levels;
• if the patient is taking eplerenone (a medicine used to treat high blood pressure).

Spironolactone is contraindicated in children and adolescents with moderate or severe renal impairment.

Warnings and precautions

Before starting Spironol, the patient should discuss it with their doctor or pharmacist.

Taking Spironol with certain medicines, potassium supplements, or potassium-rich foods may lead to severe hyperkalemia (elevated potassium levels in the blood). Symptoms of severe hyperkalemia may include muscle cramps, heart rhythm disturbances, diarrhea, nausea, dizziness, or headache.
In the event of kidney dysfunction or failure, the patient may experience a dangerous increase in potassium levels in the blood. This can affect heart function and, in extreme cases, lead to death.
