Generic Xeomin

Xeomin (incobotulinumtoxinA) is a type of "biologic" medicine, which means it is made by using live cells and is regulated under a different set of laws than most other prescription medications. Under these laws, manufacturers are not allowed to make any generic versions of biologic drugs. Although these laws are beginning to change, it is not known when a generic Xeomin will be available.

Can I Buy Generic Xeomin?

Xeomin® (incobotulinumtoxinA) is one of a few different botulinum toxin type A products available. It is approved to treat facial lines between the eyebrows, head and neck spasms (cervical dystonia), and eyelid twitching in certain people.
Xeomin is made by Merz Pharmaceuticals, LLC. It is considered a "biologic" by the U.S. Food and Drug Administration (FDA) and is under different rules and regulations than most other prescription medications. Because it is a biologic therapy, generic versions of Xeomin cannot be made by other manufacturers.

What Is a Biologic?

Biologic products are medicinal products made using living cells or organisms. These cells or organisms are used to make complex mixtures of proteins or molecules, which are then used to make medications or vaccines.
Biologic products include many different types of medicines, such as vaccines, blood products, and gene therapies. Because they are so complex, it can be difficult for a generic manufacturer to make an identical version of the product. For this reason, generic biologics are sometimes called "biosimilars" or "follow-on biologics." Biosimilars or follow-on biologics have similar properties to the existing biologic product, but are not considered identical to the existing biologic product.

When Will a Generic Version Be Available?

It is difficult to predict when generic Xeomin might become available. Previously, regulations did not allow generic biologic versions to be made. However, these regulations are changing to allow generic manufacturers to create biologic products that are similar to ones already approved by the FDA.
