What Are Biosimilars?

Biosimilars are FDA-approved drugs that are highly similar to brand-name drugs. Biosimilars are a mixture of molecules composed of living materials.

Are biosimilars the same as generic drugs?

No. Generics have identical active ingredients to brand-name drugs and are made from synthesized chemicals.

Biosimilars are like brand-name drugs and are made from living organisms.

While biosimilars are biologically produced, generic medicines are chemically synthesized. 

Is it safe to switch to a biosimilar?

Biosimilars are FDA approved. They're as safe and effective as their brand-name counterparts.

Biosimilar products have been used in Europe for more than 10 years. A 2017 international task force determined that switching to a biosimilar drug is not associated with any significant safety or therapy risks. This is supported by multiple studies that also show no significant differences in safety or effectiveness for patients who switch from one drug to another and those who do not.

Will switching change my treatment?

No. The process and experience will be the same. You should expect the same effectiveness as you do from the drug you are taking currently.

Why am I being asked to switch?

The biosimilar is a safe and cost-effective option to treat your condition. This allows the health plan to cover these high-cost products while keeping the cost of health care affordable.
