Breaking down biosimilars for you
First, let’s break down biologics. These are medications made from living sources. You might have taken one in the past. Or you may be on one now. Biosimilars are FDA-approved medications that are highly similar to the original biologic drug, also known as the reference product. They’re carefully tested. That’s to be sure there's no clinically meaningful differences from the original drugs. You'll have a similar response in your body. You'll take them the same way. And you'll have the same possible side effects. You can be sure that your biosimilar works the same. And it's just as safe as the biologic.
CVS Specialty is available to provide you with personalized support as you start or consider starting on a biosimilar, and will help you stay on track with your medication treatment plan.
So, what exactly ARE biosimilars?
A biosimilar is an FDA approved medicine that has been developed to be highly similar to the original biologic reference product and has no clinically meaningful differences compared to it. Biosimilars work the same way as the original biologic reference product by creating a similar response in your body. They are taken the same way and have the same possible side effects.
Biosimilars are not a new concept and have been available and used successfully for years. Biosimilars may be more cost effective for you and provide greater access to biologic and biosimilar treatment options. When there is more than one medication available to treat a condition, pricing usually becomes more competitive. We work to keep costs the same or less for you as you are making this transition.
Our CVS Specialty CareTeam is ready to assist you with all of your biosimilar needs, from injection training and nursing to connecting you with needs-based and non-needs-based financial assistance programs.
We are always available to chat and answer any questions online 24 hours a day.
We will work with your healthcare provider to obtain a new biosimilar prescription when required by your prescription benefit plan.
Our dedicated teams will help guide you and keep you informed every step of the way.
Keeping you healthy is our top priority.

About Biosimilars
Biologics are medications made from living sources. They're complex to make. Some examples of biologics are insulin, hormones and vaccines. Biosimilars are highly similar to the original biologic (reference product). They're already approved by the U.S. Food and Drug Administration (FDA). Biosimilars have no clinically meaningful differences compared to the biologic. They're as safe and effective. They offer the same treatment benefits. They have the same risks. Both are approved by the FDA to treat conditions like Crohn’s disease, rheumatoid arthritis, ankylosing spondylitis, diabetes and more. Visit Biosimilar Basics for Patients to learn more.
Yes. Biosimilars and generics are both versions of medications already approved by the FDA. Biosimilars are made from living sources. They're complex to make. They have no clinically meaningful differences from original biologic (reference product). Generics are copies of brand-name drugs. They're usually made from chemicals. Like generics, biosimilars may cost less. But lower cost doesn't mean they're not safe or effective. Manufacturers rely on the FDA's finding that the original biologic was safe and effective. Both biosimilars and generics may offer lower-cost options to more people.
Yes. If you're already using a biologic that works well, your provider might suggest that you change to a biosimilar. Especially if it costs less. Sometimes, prescription benefit plans change. They'll only cover a biosimilar. The FDA makes sure that biosimilars are as safe and effective as the original biologic (reference product). They have the same risks and benefits. Most are available in the same strength, dosage and device type as the biologic, too.

Not all original biologics have a biosimilar option.

It depends. Biosimilars may cost less. You have access to more options to treat your condition. That often helps lower costs. But that doesn't mean it's less effective or safe.

Getting Started
It depends. If you fill your prescription for Humira or Stelara at CVS Specialty® and your prescription benefit plan has made a formulary change to no longer cover your original biologic (reference product), CVS Specialty will contact your provider. They’ll go over alternative medications covered by your plan. Your provider can review your prescription benefits plan and select the appropriate covered medication.

It depends. If you already have a prior authorization (PA) for Humira, most prescription benefit plans will transition the existing Humira PA to the covered biosimilar. If your Humira PA has expired or your provider selects another therapy, then a new PA will be required.
If a biosimilar for Stelara or new medication is selected, a new PA is required. Your provider will need to send a new prescription and submit a new PA. Contact your prescription benefit plan for more information.
Yes. If you’re affected, most prescription benefit plans will notify you by mail 30-60 days before changes are made to the list of covered medications. The letter will inform you that your original biologic (reference product) will no longer be covered. It will list covered alternative medications and when the change will happen. CVS Specialty® will contact your provider. They’ll go over alternative medications covered by your plan. CVS Specialty will continue to fill your original biologic until the new medication coverage starts. After that, you’ll receive the alternative medication selected by your provider.

If you know the biosimilar covered by your plan, visit the manufacturer website. Find info on their financial assistance programs.
Yes. CVS Specialty can help connect you to third-party financial assistance programs. If you’re approved for assistance, you typically qualify for one year. Some financial support has an amount limit. You must reapply each year. Funding is different for each manufacturer, organization, foundation or program.

Yes. Many non-profit foundations and patient advocacy groups have resources to help you with out-of-pocket costs.

Prescription benefit plans vary in how they deal with copay cards and patient assistance programs (PAP). Some count the copay toward your deductible or out-of-pocket (OOP) maximum. In these cases, your deductible and OOP costs may be less. Other plans have a copay accumulator program. They don’t count the copay card or PAP towards your deductible or OOP. In those cases, you may be responsible for paying the entire deductible and OOP amounts based on your prescription benefit plan. It’s important to know how your plan deals with PAP and copay cards.
