1996 – Early research shows finasteride (Propecia, Proscar) linked to sexual side effects

Posted in Propecia / Proscar

In 1996, that is, 16 years before the FDA required that Merck & Co., Inc. update warning labels for products containing finasteride, such as the hair loss drug Propecia and the BPH drug Proscar, a study by S.C. Chueh et al. was published in The Journal of The Formosan Medical Association titled “Treating benign prostatic hyperplasia with finasteride in Chinese men: one-year experience.” acknowledging that very risk.

About their study, the Chueh (1996) team wrote “To evaluate the long-term efficacy and safety of finasteride in the treatment of symptomatic benign prostatic hyperplasia (BPH), 50 patients with symptomatic BPH were initially evaluated in a double blind, placebo-controlled study for 6 months. The patients were then treated with finasteride in an open extension study in which all received the same dose of finasteride (5 mg/day) for another 6 months.”

Though prostate size decreased with finasteride treatment, researchers found that 4% of subjects suffered decreased libido, and another 4% suffered impotence.  After the study period (12 months), another 2% suffered decreased libido.  While this study was overall small in size, and not actually intending to test the prevalence of sexual side effects in finasteride patients, it can be used in a Propecia lawsuits or a Proscar lawsuit to demonstrate to a court that the Merck knew, or should have known, the risks associated with its products.
