Spironolactone manufacturers?

Which companies manufacture spironolactone (brand and generic)?

Spironolactone is available from many generic manufacturers and branded product makers, depending on the country and formulation (tablets vs. other forms). The exact manufacturer on your prescription label usually reflects the specific generic “product” dispensed at the pharmacy rather than a single global supplier.

What determines the manufacturer on your prescription?

In most markets, spironolactone’s active ingredient is generic, so the “manufacturer” you see can change based on:
- the specific generic product name (including strength, dosage form, and manufacturer listed on the package)
- pharmacy supply contracts/substitution
- whether you’re using a branded version (if available locally)

How to find the exact manufacturer for the spironolactone you have

Check the box or bottle label for:
- the drug name and strength (e.g., spironolactone tablets 25 mg)
- the label text near “Manufactured for/Distributed by”
- the National Drug Code (NDC) number (US), which ties to a specific product/manufacturer

If you share your country and the strength + whether it’s tablets or another form, I can help you narrow down how to identify the current manufacturer from the label (and any brand/generic options commonly sold there).
