Doxazosin generic and brand name?

What are the generic and brand names of doxazosin?

Doxazosin is the generic name for a prescription medicine used for conditions such as high blood pressure and benign prostatic hyperplasia (BPH). [1][2]

Common brand names that sell doxazosin include:
- Cardura [1][2]
- Cardura XL (extended-release) [1][2]

Is “doxazosin” the same medicine as Cardura and Cardura XL?

Yes. Cardura and Cardura XL are brand products that contain doxazosin, with Cardura XL being the extended-release formulation. [1][2]

Are there other brand names or only these two?

Brand availability can vary by country and manufacturer, but Cardura and Cardura XL are the main widely recognized brands for doxazosin. [1][2]

How do generic doxazosin and brand doxazosin differ?

Generic doxazosin is the same active ingredient (doxazosin) as the brand products. The key difference is typically the manufacturer and excipients, not the drug’s intended effect; extended-release versions (like Cardura XL) differ by release mechanism rather than by brand vs generic. [1][2]

What should patients check on the label?

To make sure they’re matching the right product, check whether it’s:
- immediate-release doxazosin (often associated with Cardura), or
- extended-release doxazosin (often associated with Cardura XL). [1][2]
