WELCOME. We’re glad you’re here.

GREENSTONE, a US-based company owned by Pfizer Inc., has been providing Authorized Generic versions of original brand-name drugs for over 25 years.

What is an Authorized Generic?

An Authorized Generic drug is made by the manufacturer of the original brand-name drug but does not use the brand name on the label and may have a different color or marking. GREENSTONE Authorized Generics are available at generic pricing.* All generics are bioequivalent to the brand (meaning they work in the same manner when given in the same way and at the same dose) and meet FDA's quality and manufacturing standards.

Committed to high-quality generics.

• GREENSTONE Authorized Generics are manufactured to the same standards and at the same facilities as Pfizer brand-name drugs^†
• GREENSTONE Authorized Generics carry the legacy of the brand-name products' years of clinical research, data, and patient and physician experience
