Authorized Generics
Exclusively Through the Costco Member Prescription Program!
Authorized Generics (AGs) offer members a choice when it comes to prescription medications. An AG is identical to the brand name product and is priced as a generic. AGs serve as an alternative to high cost brand name products and as an option for members that prefer to purchase medications manufactured in the same facilities and with the same standards as the brand name product.

What is an Authorized Generic?

Authorized Generics (AGs) are drugs manufactured by the brand name company or a partner company that specializes in making AGs. Most AGs are manufactured in the US or in Europe and are marketed as a generic under private label. AGs are identical to the brand name drug in dosage, strength, color, shape, performance and quality but are priced as generics.

What is the difference between an Authorized Generic and a generic Drug?

An Authorized Generic (AG) is the brand company's own product repackaged and marketed as a generic drug. An AG is identical to the brand name product.

A generic drug is bioequivalent to the brand name product and meets the FDA's quality and manufacturing standards. It has the same active ingredients, dosage form, strength, route of administration, and intended use as the brand name drug. A generic drug may differ from the brand-name product in its inactive ingredients, color, shape, and size.


Are Authorized Generics priced similarly to generic drugs?

Authorized Generics, being identical to the brand name product, are typically priced higher than generic drugs. For this reason, Costco is partnering with different brand manufacturers to bring Authorized Generics at a competitive price to Costco members exclusively through the Costco Member Prescription Program (CMPP).

Drug Name/Strength Quantity CMPP Price*
Atorvastatin 10mg by Apotex 90 $15.99

Do all brand medications have Authorized Generics?

Not all brand medications have an Authorized Generic.

What Authorized Generics are available at Costco Pharmacy?

Costco Pharmacy has partnered with GREENSTONE, a Pfizer Company, to provide Costco members competitive pricing on high quality Authorized Generics (AGs)

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