Can I Buy Generic Invega Sustenna?
Invega Sustenna is manufactured by Janssen Pharmaceutica N.V. for Janssen Pharmaceuticals, Inc. It is protected by patents and exclusivity rights that prevent any
generic Invega Sustenna from being manufactured in the United States.
When Will a Generic Version Be Available?
The first patent is set to expire in April 2013. This is the earliest predictable date that a generic version could become available.
However, other circumstances could come up to extend or shorten this exclusivity period. This could include such things as lawsuits or other patents for new
Invega Sustenna uses. Once the patent expires, there may be several companies that manufacture a generic Invega Sustenna drug.
Is Paliperidone Palmitate a Generic Invega Sustenna?
No --
paliperidone palmitate is the active ingredient in Invega Sustenna, not a generic version of it. What can be confusing is that the active ingredient of a drug is often referred to as the "generic name." The generic name is different from a generic version of a medicine.
In order for there to be a generic version of a medicine, the original medicine must have gone off-patent, and another company besides the original manufacturer must make the product.
