When Will There Be a Generic Ambien CR?
The patent for Ambien CR is not expected to expire until 2020. This is the earliest possible date that a generic version of Ambien CR could become available. However, there are other circumstances that could come up to extend the exclusivity period of Ambien CR beyond 2020. This could include such things as other patents for specific Ambien CR uses or lawsuits. Once Ambien CR goes off patent, there may be several companies that manufacture a generic Ambien CR drug.
