FDA inaction on hair loss drug’s suicide, depression, erectile dysfunction risk sparks lawsuit


Consumer advocacy group Public Citizen filed a lawsuit on Sept. 8 on behalf of the Post-Finasteride Syndrome Foundation (PFSF) against the Food and Drug Administration for the agency’s failure to act on a petition submitted by the foundation 4 years ago.

The September 2017 petition requested that the FDA take the popular hair-loss drug (1 mg finasteride, Propecia) off the market because of evidence of serious risk of patient injury, including depression and suicidal ideation.

As an alternative, PFSF requested that the FDA require the drug’s manufacturers revise the safety information on the labeling and add boxed warnings to disclose the potential for side effects, another of which is erectile dysfunction.

Public Citizen points to a recent analysis of the VigiBase global database, which tracks adverse effects from global pharmacovigilance agencies, lists 356 reports of suicidality and 2,926 reports of psychological adverse events in finasteride users. Yet, 4 years after submitting the petition, the FDA has neither granted nor denied it.

The lawsuit claims that FDA has acted unlawfully in failing to act on PFSF’s petition, and further cites “88 cases of completed suicide associated with finasteride use” per data from the VigiBase database.

“On the same day that PFSF submitted the petition, FDA’s docket management division acknowledged receipt and assigned the petition a docket number,” Michael Kirkpatrick, the Public Citizen attorney serving as lead counsel for PFSF, told this news organization.

Yet, to date, “there has been no substantive response to the petition. The lawsuit filed today seeks to force FDA to issue a decision on PFSF’s petition,” Mr. Kirkpatrick said.

“The FDA needs to act in a timely way to protect the public from the risks associated with use of Propecia. The FDA’s failure to act exposes consumers to potentially life-threatening harm,” he added in a statement.

The complaint filed today by Public Citizen in the U.S. District Court for the District of Columbia is available online.

This news organization reached out to the FDA for comment but did not receive a response by press time.
