Is desvenlafaxine available as a generic drug?
Yes. Desvenlafaxine (the active ingredient in products such as Pristiq) has generic versions available in some markets, depending on the country and manufacturer.
What brand-name product does generic desvenlafaxine replace?
In the U.S., the main brand associated with desvenlafaxine is Pristiq (desvenlafaxine extended-release). Generic desvenlafaxine extended-release products are intended to provide the same active ingredient and dosing.
How can I tell if a prescription is for generic desvenlafaxine?
Ask your pharmacist for the active ingredient on the label:
- The generic should list “desvenlafaxine” (often with “extended-release”).
- The brand will list “Pristiq” (or another brand), but the active ingredient will still be desvenlafaxine.
Is it the same as the extended-release formulation?
Typically, generic desvenlafaxine is supplied as an extended-release product to match the original brand formulation. If your prescription is for “extended-release,” you usually want the generic with the same release type.
