Merck's Drug Propecia Linked To Sexual Dysfunction

zaxios writes "Merck — the pharmaceutical giant previously featured on Slashdot for drawing up a 'hit list' of doctors that criticized its drug Vioxx, and creating a fake medical journal to endorse its products — is embroiled in a new scandal. USA Today is reporting on two new studies that show Propecia, Merck's $250 million prescription medication for baldness, can make men irreversibly impotent. Lawsuits have been filed in the United States and Canada from men claiming to have permanently lost their sexual function after taking the drug. All this is reminiscent of Merck's difficulties with Vioxx, a once $2.5-billion-a-year drug, which was withdrawn from the market in 2004 after a study showed it doubled the risk of heart attack and stroke in users."

    ...Propecia is an anti-androgen! Duh.

  2. This drug really screws up female fertility by Anonymous Coward · · Score: 5, Interesting

    20 years ago, I knew a lady who worked at Merck, about the time Propecia was "discovered". In reality, it was developed as a drug for another purpose (something to do with the prostate) and the hair growth was a side effect. She, and no other females, were allowed in the production area, as exposure caused irreversible infertility in females, and it was really bad for pregnant women.

  3. Not surprised by BlueParrot · · Score: 5, Interesting

    I'm transsexual and take testosterone blockers in order to help feminise my body, and changes in sex drive were quite noticeable. Propecia's active substance, finasteride, is essentially a testosterone blocker ( thou admittedly a weaker one than what I am taking ) so I'm not at all surprised it can have such side effects.

    Unfortunately it only grows pubic hair. Would have been a hit in the 70s, but these days...

    My other reason for cutting it all off was that I have exceptionally oily skin and it's much easier to get all the sebaceous cysts cut out with short hair, and I get a bunch of cool scars :)

    FINALLY! I thought a thread related to sexual function was bound to have some sexy anecdotes, but it took until this to find one.

    Whether a drug is worth the risk for the benefits should be up to the PATIENT, not some damned ambulance chaser!

    Right, and in this case the patients weren't warned of the risk of irreversible impotence, only reversible impotence that was supposed to go away after they stopped taking the drug. They weren't in any position to weigh up the real risks and benefits, and have every right to sue the pharmaceutical company for that.
