Aldactone 100mg

Aldactone 100mg (spironolactone) is a potassium-sparing diuretic used to treat conditions like hypertension, heart failure, and edema. It works by blocking aldosterone, a hormone responsible for fluid retention, helping reduce excess water while maintaining potassium levels.

Additionally, it’s prescribed for hormonal disorders like hyperaldosteronism and even acne or hirsutism in certain cases.

Unlike loop diuretics, Aldactone prevents excessive potassium loss, making it a preferred choice in some patients. However, it requires careful monitoring due to potential side effects like hyperkalemia, dizziness, or breast tenderness.

Uses

• Hypertension (High Blood Pressure) – Helps lower blood pressure by reducing excess fluid retention.
• Heart Failure – Reduces fluid buildup and decreases strain on the heart.
• Edema – Treats swelling caused by liver disease, kidney disease, or heart failure.
• Hyperaldosteronism – Manages excess aldosterone production, which can cause high blood pressure and potassium imbalance.
• Polycystic Ovary Syndrome (PCOS) – Helps with hormonal imbalances, acne, and hirsutism (excessive hair growth).
• Acne & Hirsutism – Used in women to reduce androgen-related skin issues.
• Hypokalemia (Low Potassium Levels) – Helps retain potassium in the body.

How to use Aldactone 100mg ?

Aldactone 100mg should be taken exactly as prescribed by a doctor. It is usually taken once or twice daily, with or without food. Swallow the tablet whole with water. To avoid frequent urination at night, take it earlier in the day. Dosage depends on the condition being treated.

Regular blood tests may be needed to monitor potassium levels. Do not stop or adjust the dose without medical advice. Avoid potassium supplements unless directed by a doctor to prevent hyperkalemia.

How dose it works ?

Aldactone 100mg (spironolactone) works by blocking aldosterone, a hormone that regulates salt and water balance in the body. Aldosterone promotes sodium and water retention while excreting potassium.

By inhibiting its action, Aldactone helps the kidneys remove excess sodium and water while retaining potassium, reducing fluid buildup and lowering blood pressure. This makes it effective for conditions like hypertension, heart failure, and edema.

Additionally, it has anti-androgen properties, which help in treating hormonal conditions like PCOS, acne, and hirsutism by reducing excess male hormones in women.

Dosage

The dosage of Aldactone 100mg (spironolactone) varies depending on the condition being treated.

• Hypertension (High Blood Pressure): 25–100mg daily in one or divided doses.
• Heart Failure & Edema: 25–200mg daily, depending on severity.
• Hyperaldosteronism: 100–400mg daily (short-term diagnosis) or 5–20mg/kg body weight (long-term management).
• PCOS, Acne, Hirsutism: 50–200mg daily, often combined with other treatments.
• Hypokalemia (Low Potassium): 25–100mg daily.

Dosage adjustments may be necessary based on response and potassium levels. Do not self-adjust; overdose risks hyperkalemia.

Benefits of Aldactone 100mg (Spironolactone):

• Reduces High Blood Pressure – Lowers blood pressure by eliminating excess fluid while retaining potassium.
• Treats Heart Failure – Decreases fluid buildup, reducing strain on the heart.
• Manages Edema – Helps with swelling caused by kidney, liver, or heart conditions.
• Controls Hyperaldosteronism – Regulates excessive aldosterone production, preventing potassium loss.
• Improves PCOS Symptoms – Reduces acne, hirsutism (excess hair growth), and hormonal imbalances.
• Prevents Hypokalemia – Maintains potassium levels in patients losing too much through urine.
• Supports Liver Cirrhosis Treatment – Reduces fluid retention and ascites.
