Propecia can cause serious side effects

As many of our clients have come to learn, this past April, the Food and Drug Administration (FDA) updated the warning to finasteride, Merck & Co.’s drug Propecia™ and Proscar™ marketed to treat both male pattern baldness and enlarged prostate. Propecia Findings make me suspicious that this drug may have done permanent damage to these men

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.

On the heels of that warning, the Journal of Sexual Medicine has published a report by Dr. Michael Irwig of George Washington University. The report contains a study of men who under age 40 who reported experiencing side effects for three months or more after taking Propecia to treat hair loss. 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™.

Dr Irwig notes that the “findings make me suspicious that this drug may have done permanent damage to these men,” and, “The chances that they will improve? I think it’s lower and lower the longer they have these side effects.”
