An article that appeared recently in Time Magazine details long lasting sexual side effects suffered by men taking Propecia to combat hair loss. Dr. Michael Jasin, Medical Director of the Jasin Hair Transplant Institute in Tampa, Florida has warned patients to be aware of the downsides to Propecia as a cure for baldness and does not prescribe Propecia as part of his hair restoration practice.
Dr. Jasin believes in staying informed and educating his patients. He firmly believes that the best patient is an informed patient. Earlier this year, Dr. Jasin, posted a blog on hair loss medications which contained information about the side effects of finasteride (Propecia). In the article, he noted that while sexual side effects are rare, they can often be serious. The adverse effects include impotence, abnormal ejaculation, abnormal sexual function and testicular pain, but the more recent study notes that ceasing to take Propecia may not reverse the side effects. He also stated that “medicines such as Propecia do not work for all patients and in fact, seldom will trigger hair growth in the temples where hair loss is most noticeable.” For men (and women) suffering from hair loss, the only permanent solution is a hair transplant.

Propecia Problems: Baldness Drug Linked with Long-Lasting Sexual Side Effects
By Alexandra Sifferlin | @acsifferlin | Time Magazine – July 12, 2012
In April, the Food and Drug Administration (FDA) updated the warning to finasteride, Merck & Co.’s drug marketed to treat both male pattern baldness (Propecia) and enlarged prostate (Proscar). The new warnings noted that the sexual side effects associated with the medication, including problems with libido, ejaculations and orgasm, could last even after patients stop taking the drug.
Now a new study published in the Journal of Sexual Medicine finds that side effects may not only continue after stopping finasteride, but they may last for months or even years.
In the study, Dr. Michael Irwig of George Washington University and his colleagues surveyed 54 men under age 40 who reported experiencing side effects for three months or more after stopping the medication Propecia. The patients reported a variety of sexual problems including erectile dysfunction, low libido, trouble having an orgasm, and shrinking and painful genitals. Some men also reported neurological problems like depression, anxiety and cognitive haziness.
For 96% of the men, the sexual problems lasted more than a year after they quit using the drug. None of the men had sexual, medical or psychiatric complaints before taking Propecia.
The study sample was small and the authors acknowledge that it may be skewed to include only men who were most negatively impacted by the drug. Most of the participants were recruited through an Internet forum called Propeciahelp.com, for men experiencing persistent side effects.
Still, the authors argue their findings may signal potentially serious risks for men using finasteride. “Our findings make me suspicious that this drug may have done permanent damage to these men,” Irwig told ABC News. The FDA’s updated warning labels for finasteride were based on a review of post-marketing reports of sexual dysfunction. The agency reviewed 421 post-marketing reports of sexual side effects related to Propecia from 1998 to 2011; out of these cases, 59 reported adverse sexual effects lasting over three months after discontinuing the drug. For Proscar, the FDA reviewed 131 cases of erectile dysfunction and 68 cases of decreased libido from 1992 to 2010. As Healthland reported in April:
Finasteride labels will now warn users that Propecia’s side effects can include libido disorders, ejaculation disorders, and orgasm disorders that continue after discontinuation of the drug and that Proscar can lead to decreased libido that continues after quitting the drug. Both medications will receive a new description of reports of male infertility and poor semen quality that normalized or improved after stopping therapy. “Despite the fact that clear causal links between finasteride (Propecia and Proscar) and sexual adverse events have not been established, the cases suggest a broader range of adverse effects than previously reported in patients taking these drugs,” the FDA said in a statement.
Irwig acknowledges that the number of men experiencing long-lasting side effects from finasteride is small, although the incidence of sexual side effects in clinical trials was around 2%, the incidence of persistent sexual side effects is unknown, but likely less than 0.1%. “But because the medication is prescribed so commonly, it’s still a lot of people, likely several thousand men around the world,” Irwig told ABC News. Both the FDA and Merck maintain that finasteride is safe and effective.
