Committed to providing quality generic medications to help patients lead healthier lives

Welcome.

GREENSTONE, a US-based company owned by Pfizer Inc., one of the world’s premier biopharmaceutical companies, has been providing Authorized Generic versions of original brand-name drugs for over 25 years. GREENSTONE also provides Authorized Generics from other manufacturers in addition to several generic products. GREENSTONE Authorized Generics carry the legacy of the brand-name products' years of clinical research, data, and patient and physician experience.

GREENSTONE currently offers more than 75 different generic medications, covering a broad range of diseases. And, we’re always adding new generics to our portfolio. At GREENSTONE, we understand that access to generic medication is important; in fact, nearly 9 in 10 prescriptions filled in the United States today are for generic medications.

GREENSTONE also offers a Pharmacy Locator Service that can personally assist in locating your GREENSTONE medication at a nearby pharmacy. This helps ensure that month to month, pill to pill, your generic will look the same.
