VHOSPITAL.CLINIC · Drug Reference
Spironolactone dosing must be individualised to the patient's condition, weight, kidney and liver function, and other medications. Dosing depends on diuretic class and indication. Loop diuretics are the most potent; thiazides are preferred for hypertension. Take in the morning to avoid nocturia.
Do not exceed the prescribed dose of Spironolactone. If you miss a dose, follow the specific guidance provided with your prescription — generally take it as soon as you remember unless it is nearly time for the next dose.
Can I take a higher dose of Spironolactone if my symptoms don't improve?
No. Never increase the dose of Spironolactone without medical advice. If your current dose is insufficient, contact your healthcare provider to discuss a dose adjustment or alternative treatment.
Why should I take my diuretic in the morning?
Diuretics increase urine production for several hours after taking them. Taking them in the morning allows this effect to occur during the day rather than disrupting sleep with nocturia (frequent nighttime urination).
Describe your symptoms and concerns and get a structured clinical assessment — possible causes, red flags, and recommended next steps.
