Efficacy of Plaquenil versus a generic Hydroxychloroquine formulation

March 20, 2008 By Arthritis Center

Question

Has anyone ever questioned or compared the efficacy of Plaquenil versus a generic Hydroxychloroquine formulation? Is there any way to verify that the medications being purchased through my local pharmacy are not counterfit?

Answer

The active ingredient of brand name Plaquenil and generic hydroxychloroquine are the same.  In the United States, the manufacture of prescription drugs is highly regulated and the manufacturer is required, by federal law, to guarantee the integrity of their product, for both brand name and generic formulation.

Founded in 1998, the Arthritis Center at Johns Hopkins is dedicated to providing quality education to patients and healthcare providers alike.
