7 stats that show what providers think about biosimilars

Overcome barriers to adoption with ongoing outreach and education


From the Editors


Market competition will continue to increase and drug costs will decrease as more biosimilars launch. Although 2023 is shaping up to be a big year for biosimilars, barriers remain to widespread acceptance, including provider hesitation. The adoption of biosimilars depends on whether providers prescribe them.

Physicians may be more comfortable initiating treatment with a biosimilar if they’ve prescribed biosimilars in the past with success or if a patient is new to therapy. They’re less likely to switch a patient doing well on their existing drug therapy regimen to a biosimilar.

So, what do physicians think about these innovative products?


80% are concerned about reimbursement1

Some reimbursement policies may not encourage providers to use lower-cost biosimilars. Another challenge for providers is keeping up with the complexity of payor reimbursement strategies as new drugs come to market.


76% are concerned about patient disruption2

Starting a new medication or being switched to a biosimilar can be intimidating for patients who may face potential side effects and cost implications.
