Yaz vs Drospirenone: are they the same?
Yaz is a commercial brand whose active ingredient is exactly Drospirenone. This page explains what that means in practice: where they differ (brand, manufacturer, price, available strengths), why they are clinically equivalent, and when the brand or an authorised generic is the better choice.
Are they the same?

The practical differences are manufacturer, excipients (rarely matters except in specific sensitivities), tablet appearance and price. The brand is preferred by some patients for personal reasons or insurance coverage; the generic is the default when cost matters.
