Generic Pediarix

There are no generic versions of Pediarix, as certain laws are currently preventing "biologic" medications from being manufactured in generic form. However, recent legislation has aimed at changing these laws. It is predicted that new laws and regulations will allow generic biologics in the near future.

Generic Pediarix: An Overview

Pediarix® (DTaP, hepatitis B vaccine, and inactivated polio vaccine) is a combination vaccine. It combines three standard childhood vaccines: DTaP (diphtheria, tetanus, and pertussis vaccine), the hepatitis vaccine, and the inactivated polio vaccine. It is given as three separate doses.
 
Pediarix is made by GlaxoSmithKline Biologicals. There are no generic versions of Pediarix.
 
Technically, Pediarix is considered to be a "biologic" medication and is, therefore, under different rules and laws than most other medications. At this point, generic biologics (including generic Pediarix) are not allowed to be made. However, the laws are changing, and it is likely that generic biologics will be permitted in the near future.
 

Biologics and Generics

When the patents for regular drugs expire, other manufacturers can apply to make generic versions. These companies need to submit a little information proving that their product is equivalent to the brand-name drug, but they do not have to repeat all of the human studies to show the drug to be safe and effective. Human studies are very expensive and time-consuming, and generic medications are less expensive because they do not need all the human studies.
 
However, biologics (medications made using live cells or organisms, also known as "biopharmaceuticals") are regulated under a different set of laws. Under these laws, there is no way for a generic biologic to be approved, unless the generic manufacturer completes all of the human studies necessary to approve a brand-new drug.
 
Because such studies are extremely expensive, it is likely that a generic biologic would not be any less expensive than the brand-name product. Essentially, if a generic biologic were to be approved, it would not really be a generic, but a new and separate drug (that would not be equivalent to the brand-name product).
 
However, recent legislation has aimed at changing these laws. It is predicted that new laws and regulations will allow generic biologics in the near future.
