Is aldactone and spironolactone the same?

Are Aldactone and spironolactone the same medication?

Yes. Aldactone is a brand name, and spironolactone is the generic (active) drug. They contain the same active ingredient, spironolactone, so they are considered equivalent in that sense.

What does that mean for dosing and switching?

Because they use the same active ingredient, switching between Aldactone and generic spironolactone is typically treated as switching between brand and generic versions. Your prescriber or pharmacist may still adjust dosing or monitor you, especially if you have conditions where small changes could matter (for example, kidney disease or potassium issues).

Are there differences at the pill level?

The active drug is the same, but the inactive ingredients (the fillers/coatings) can differ between brands and generics. Those differences usually do not change how the medication works, but they can matter for people with specific sensitivities.

Why do people get different names on prescriptions?

Prescriptions often show the generic name (spironolactone), while the pharmacy may dispense a brand (like Aldactone) depending on what’s available and what’s covered by insurance.
