Our study found no significant link between oral finasteride and reports of depression or suicide from 2006 to 2011. However, a significant number of such reports emerged during 2013–2018 and 2019–2023, potentially due to increased awareness of adverse effects following the identification of PFS in 2012. [T]o ensure patient safety, all patients should be screened for mood alterations, depression, and suicidal ideation by a health care professional prior to being prescribed finasteride.
