Does Propecia Cause Permanent Impotence?

Thursday, 12 Jul 2012 04:33 PM


Using drugs to combat hair loss can cause erectile dysfunction, according to a new study by The George Washington University School of Medicine and Health Sciences. The research, which will be published in The Journal of Sexual Medicine, suggests men who take the drug finasteride, commonly marketed under the trademark names Propecia and Proscar, may endure an on-going reduction in sex drive, and in some cases, prolonged periods of erectile dysfunction, even after they stop using the medications. Researchers found that the side effects could last for months — even years — after they stopped using the medication.
Researchers interviewed 54 men under the age of 40. All reported sexual problems for at least three months after taking the hair-loss medications. They reported a variety of sexual side effects including erectile dysfunction, and shrinking and painful genitals. Some even reported neurological problems, such as depression and anxiety.
The sexual problems lasted more than a year for 96 percent of the men, and the lasting problems make researchers wonder if the drug has done permanent damage.
The new study follows one released last year that also found a link between hair-loss drugs and sexual side effects.
“The study looked at the reported types and duration of persistent sexual side effects in otherwise healthy men who took finasteride for male pattern hair loss,” Dr. Michael Irwig, Assistant Professor of Medicine, said of the first study. “While finasteride has been associated with reversible adverse sexual side effects in multiple randomized placebo controlled trials, this is the first series to find that symptoms persisted for at least three months despite stopping finasteride,” said Irwig, who was lead author of both studies.
In the 2011 study, Dr. Irwig conducted standardized interviews with 71 men aged 21 to 46 who said they were in good health but claimed they experienced the onset of sexual side effects after they began finasteride. Of the men studied, 94 percent said they developed low sexual desire, 92 percent said they developed erectile dysfunction, 92 percent said they developed decreased arousal, and 69 percent said they developed problems with orgasm. The men said they used finasteride for an average of 28 months, and they reported an average duration of persistent sexual side effects 40 months from the time of stopping finasteride to the interview date.
Additionally, the study found the number of sexual episodes the survey respondents reported per month dropped, and their total sexual dysfunction score increased before and after finasteride use, according to the Arizona Sexual Experience Scale. Although the exact incidence of persistent sexual dysfunction is unknown, Dr. Irwig recommends that men who are considering using finasteride discuss the potential risk for persistent sexual side effects with their doctors.
The FDA was aware of sexual side effects in clinical trials, but the percentage of men affected appeared to be small. After more than 400 reports, the FDA required a label change that warned of sexual side effects for Propecia and Proscar in 2011. Patients have filed a class action lawsuit against pharmaceutical manufacturer Merck over the drug's side effects.
