Generic Silenor

Because Silenor (doxepin tablets) is protected by patents, no generic version of this medication is available at this time. The first patent is set to expire in March 2013, which is the earliest predictable date that a generic version may be manufactured. It's important to note that doxepin is the active ingredient in this product, but it is not the same thing as a "generic version."

Is Doxepin a Generic Silenor?

No -- doxepin hydrochloride is the active ingredient in Silenor, but it is not a generic version of it.

There are generic versions of doxepin capsules (not tablets, like Silenor), but these capsules come in much higher strengths and are not equivalent to Silenor.
