Who makes spironolactone tablets and generics in the US?
Spironolactone is an older, widely generic medicine, so it’s sold by many manufacturers under different brand names (and mostly as generics). The specific manufacturer for a given prescription depends on the product strength, dosage form (tablet vs. suspension, if applicable), and the pharmacy’s current supply.
How can I check the exact manufacturer on my bottle?
To find the manufacturer for the spironolactone you received, check the following on your prescription label or bottle:
- Generic name (spironolactone) plus the strength (e.g., 25 mg, 50 mg, 100 mg)
- “Manufactured for” / “Distributed by” lines
- The National Drug Code (NDC) number
- Sometimes the company name appears near the NDC
The NDC is the most reliable way to identify the exact product and manufacturer.
If you mean the original brand manufacturer (Aldactone)
Spironolactone’s original brand is Aldactone. The manufacturer information for Aldactone can differ by country and over time, and pharmacies typically fill prescriptions with generics rather than the brand.
Which manufacturer should you ask for if you want a specific one?
If you want a specific manufacturer (for example, for consistency of pill appearance or dosing), ask your pharmacist if they can fill using a particular NDC. Pharmacies often can switch to another NDC that matches a requested manufacturer when available.
