Brand-name vs biosimilar drugs Dupixent is only available as a brand-name drug. Dupixent contains the active ingredient dupilumab, which is a biologic drug. It doesn’t come in a biosimilar version. A biosimilar medication is a drug that’s similar to a brand-name medication (the parent drug). Biologics are made from living cells. It’s not possible to make an exact copy of these drugs. A generic, on the other hand, refers to medications made from chemicals. A generic is an exact copy of the active drug in a brand-name medication. Biosimilars are considered to be just as safe and effective as their parent drug. And like generics, biosimilars tend to cost less than brand-name medications.Why are costs different for brand-name drugs vs. generic drugs? Brand-name drugs can be expensive because of the research needed to test their safety and effectiveness. The manufacturer of a brand-name drug can sell it for up to 20 years. When the brand-name drug’s patent expires, multiple manufacturers can create generic versions. This marketplace competition may lead to lower costs for generics. Also, because generics contain the same ingredients as brand-name drugs, they don’t require the same costly testing. Ways to reduce long-term drug costs If you take Dupixent long term, you may be able to lower its cost in the following ways: Getting a 3-month supply You may be able to get a 90-day supply of Dupixent. If approved by your insurance company, getting a 90-day supply of the drug could reduce your number of trips to the pharmacy and help lower the cost. If you’re interested in this option, check with your doctor, pharmacist, or insurance provider.

Using this type of service may help lower the drug’s cost and allow you to receive your medication without leaving home. Some Medicare plans may help cover the cost of mail-order medications.
