Kesimpta is a biologic drug, which means it’s made from parts of living organisms. It doesn’t come in a biosimilar form. Biosimilars are like generic drugs. But unlike generics, which are made for nonbiologic drugs, biosimilars are made for biologic drugs.

Why is there such a cost difference between biologic drugs and biosimilar drugs?

Biologic drugs can be expensive because of the research and testing needed to ensure their safety and effectiveness. The manufacturer of a biologic drug can sell it for up to 12 years. When the biologic drug’s patent expires, other drugmakers can create biosimilar versions. This competition in the market may lead to lower costs for biosimilars. And because biosimilars are very similar to biologic drugs, they don’t need to be studied again. This can also lead to lower costs for biosimilars.

If you take Kesimpta long term, you may be able to lower your costs in the following ways:

  • Look into getting a 90-day supply of your medication. You may be able to get a 90-day supply of Kesimpta if approved by your insurance company. This could reduce your number of trips to the pharmacy and help lower the cost of the drug. If you’re interested in getting a 90-day supply of Kesimpta, talk with your doctor, pharmacist, or insurance provider.
  • Use a mail-order pharmacy to get your medication. Using a mail-order pharmacy might help lower your cost for Kesimpta. Plus, you could get your medication without leaving home. Some Medicare plans may help cover the cost of mail-order drugs. You may also be able to get a 90-day supply of the drug through mail order. If you don’t have health insurance, talk with your doctor or pharmacist. They may be able to suggest online pharmacy options that could work for you.

If you still have questions about the cost of Kesimpta, talk with your doctor or pharmacist. They may be able to give you a better idea of what you’ll pay for this drug. But if you have health insurance, you’ll need to talk with your insurance provider to learn the actual cost you’d pay for Kesimpta.

Examples of questions you may want to ask your doctor or insurance provider include:

  • Does Kesimpta’s cost vary according to the dosage I’m prescribed?
  • What other treatment options do I have if I can’t afford Kesimpta?
  • How can I get a 90-day supply of Kesimpta?
