What is a biosimilar?

Biosimilars are drugs made from living material, such as bacteria or plant cells. They are modeled after another type of drug called a biologic that is also made from living material. 

Why do people use biosimilars?

Biosimilars can be used to treat a variety of health issues, including:

• Chronic skin diseases, such as psoriasis 
• Chronic bowel disease 
• Diabetes
• Arthritis
• Certain kidney conditions

• Multiple sclerosis 

• Macular degeneration 

• Certain cancers

Biosimilars are:

As safe as biologics

As effective as biologics

Less expensive than biologics

How does a biosimilar get FDA-approval?

By being shown to work in the exact same way as the reference product. 

Are biosimilars the same as generic drugs?

They are similar but not the same. 

Generics, made from chemicals, are the exact same as brand name drugs. 

Biosimilars, made from living materials, are very similar to the reference product.

Why aren’t they the exact same? 

Biologics and biosimilars are both made from living materials, so both have some variability. 

Rx

Some biosimilars are interchangeable with their reference products.  

This means you don’t need a new prescription to substitute the biosimilar for the biologic.  

(Biosimilars that aren’t interchangeable need a new prescription.)
