Report Your Side Effects

Regulatory Agencies

Anyone suffering from persistent finasteride side effects is encouraged to report them to the appropriate agency.

FDA Citizen Petition

In September 2017, the PFS Foundation filed a Citizen Petition with the FDA, asking that the agency "require the immediate removal of Propecia (and generic formulations of finasteride, 1 mg, for androgenic alopecia) from the market." To date, the FDA has not responded to the petition, but it can be accessed here at Regulations.gov.

Merck

Merck & Co., Inc. is the manufacturer of Propecia and Proscar.  To report adverse events to Merck, call the Merck National Service Center at (800)444-2080.

RxISK.org

In addition to agencies like the U.S. Food and Drug Administration and World Health Organization, PFS patients are encouraged to report their persistent side effects to RxISK.org, a global, independent pharmacovigilance organization whose database is used by patients, doctors and pharmacists to research prescription drugs and their side effects, ideally to identify problems early on in the life of a drug.
