A recent case study published in the Journal of Psychosexual Health highlights the troubling long-term effects of finasteride, a medication commonly prescribed for hair loss. A 26-year-old man reported experiencing significant sexual dysfunction, including orgasm difficulties and numbness in the penis, lasting for 19 months after he stopped taking the drug. He initially took a 1-milligram dose for six months but discontinued it due to side effects such as reduced ejaculation and loss of sexual pleasure. This case underscores the risks associated with finasteride, including post-finasteride syndrome (PFS), which can result in enduring sexual and psychological issues. The FDA has warned about potential side effects like erectile dysfunction and depression, which were echoed in reports from men who acquired the drug through telehealth platforms.
