No generic versions of Premphase have been approved in the United States. The drug is protected by a patent until January 2015, which prevents manufacturers from making generic versions. Also, Premphase contains a complex estrogen mixture that would be difficult to duplicate. In order for the FDA to approve a generic Premphase, this estrogen component would have to be identical to the brand-name medication.
