Desvenlafaxine succinate is available as a generic medication [1]. This means that the exclusive marketing rights for the branded version, Pristiq, have expired, allowing other pharmaceutical companies to produce and sell their own versions [1].
When Did Generic Desvenlafaxine Succinate Become Available?
The U.S. Food and Drug Administration (FDA) approved the first generic versions of desvenlafaxine succinate extended-release tablets in late 2019 and early 2020 [2].

What are the Benefits of Generic Medications Like Desvenlafaxine Succinate?

Generic desvenlafaxine succinate is bioequivalent to brand-name Pristiq, meaning it delivers the same amount of active ingredient into the bloodstream over the same period [1].

Patients can typically expect the same therapeutic effects and side effect profiles from the generic version as from Pristiq [1].
