Kisunla (donanemab-azbt) is a prescription drug that’s used to treat Alzheimer’s disease. Kisunla’s cost may depend on factors such as your dosage, the pharmacy you use, and whether you have health insurance.

Note: As a person’s condition progresses, they may need help reading or understanding certain information about their treatment plan. This article contains details that may help caregivers learn more about Kisunla’s cost.

The price you pay for Kisunla can vary. Your cost may depend on your treatment plan, the pharmacy you use, and your insurance coverage (if you have it).

Kisunla is given as an intravenous (IV) infusion (an injection into your vein over a period of time) by a healthcare professional. So, your cost may also depend on how much you have to pay to receive Kisunla at an infusion center or your doctor’s office.

To find out how much you’ll pay for Kisunla, talk with your doctor or insurance provider.

Kisunla 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 exclusively 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 have questions about how to pay for your prescription, talk with your doctor or pharmacist.

If you have insurance, you may need to get prior authorization before your insurance provider will cover Kisunla. This means your insurer and your doctor will discuss Kisunla in regard to your treatment. Then, the insurance company will determine whether the drug is covered. If Kisunla requires prior authorization and you don’t receive it before you start treatment, you could pay the full cost of the drug.

Be sure to ask your insurance company whether Kisunla requires prior authorization.
