What is Spironolactone 100mg?

Spironolactone 100mg is a versatile prescription medicine that has been trusted by doctors for decades. It belongs to a class of medicines called potassium-sparing diuretics — commonly known as "water pills" — but it does far more than simply remove excess fluid from the body. Spironolactone also blocks a hormone called aldosterone, which regulates salt and water balance, and counteracts the effects of androgens (male hormones), making it useful across a surprisingly wide range of conditions — from heart failure and high blood pressure to hormonal acne and PCOS in women.

What is Spironolactone 100mg Used For?

• Heart Failure — Spironolactone is used in combination with other medicines to treat high blood pressure and heart failure, lowering blood pressure to reduce the risk of strokes and heart attacks. It is also used to lessen the need for hospitalisation for heart failure. 
• High Blood Pressure (Hypertension) — Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. 
• Fluid Retention (Oedema) — This medicine is used to treat fluid retention in patients with congestive heart failure, liver cirrhosis, or a kidney disorder called nephrotic syndrome. 
• Hyperaldosteronism — Spironolactone is used to diagnose and treat hyperaldosteronism, a condition in which the adrenal gland produces too much of the hormone called aldosterone. 
• Low Potassium (Hypokalaemia) — Spironolactone is used to treat hypokalaemia, which is low potassium levels in the blood. 

How to Take Spironolactone 100mg

• The typical starting dosage is 100mg taken by mouth each day, given as a single dose or split into two doses. Some people may take as little as 25mg per day or as much as 200mg per day. 
• Can be taken with or without food, though taking it with food may help reduce stomach upset.
• Take at the same time each day for the best results and to build a consistent habit.
• For heart failure and oedema: if there is no clinical response after the initial dose, your doctor may add a second diuretic with a more specific mechanism of action. 
• For hormonal acne and PCOS: symptom relief through Spironolactone can happen within 2 to 4 months. 
• Never stop Spironolactone abruptly — always consult your doctor before making changes to your dose.

Common Side Effects

Drowsiness, dizziness, lightheadedness, stomach upset, diarrhoea, nausea, vomiting, or headache may occur. These are usually mild and often settle as your body adjusts to the medication. 

Women taking Spironolactone may also notice:

• Menstrual irregularities or spotting
• Breast tenderness
• At doses of up to 100mg daily, the adverse effect profile is similar to placebo, with the most common effects being menstrual irregularities, increased urination, headache, and dizziness. 

Seek immediate medical attention if you experience signs of high potassium (hyperkalaemia):

Symptoms to watch for include stomach pain, confusion, difficulty breathing, irregular heartbeat, nausea or vomiting, nervousness, numbness or tingling in the hands, feet, or lips, or weakness or heaviness of the legs. 

Important Warnings

Pregnancy — Do Not Use: Spironolactone is not safe during pregnancy due to its potential harm to the fetus, including interference with male genital development. Women of childbearing age should use reliable contraception while on this medication and must inform their doctor immediately if they become pregnant. 

High Potassium Risk: Spironolactone may cause dehydration and electrolyte imbalance. Tell your doctor right away if you have symptoms including unusual dry mouth or thirst, muscle cramps or weakness, slow, fast, or irregular heartbeat, or confusion. 

Use with Caution if You Have: Kidney problems, high levels of potassium in your blood, Addison's disease, or if you are unable to urinate. 

Elderly Patients: Elderly patients are more likely to have age-related kidney problems, which may require caution when taking Spironolactone.
