Lawsuit Blames Hair Loss Drug For Sexual Dysfunction And Mental Problems
A Connecticut law firm has filed a lawsuit against pharmaceutical manufacturer Merck & Co. on behalf of men who have taken Propecia, a prescription drug that combats hair loss but, its critics say, can also cause severe side effects such as sexual dysfunction and mental impairment.
One Connecticut patient…said that he stopped taking Propecia three years ago after experiencing trouble breathing, sexual dysfunction, anxiety attacks and memory loss. He asked not to be named because his mother still does not know of the severe side effects the drug caused.

Propecia Website Down
Patients looking for information about Propecia may have to search more than anticipated now that the Propecia website has been taken down. The move has sparked speculation about Propecia lawsuits and Propecia side effects.
Although the warning label in the US alerts patients to the possibility of sexual side effects, the label also states that the side effects are temporary… Warning labels in Europe reportedly contain information that the sexual side effects could be permanent.

Canadian Men in Class Action Lawsuits Say Drug They Took for Baldness Has Left Them Impotent
More than 500 Canadian men feel they weren’t warned properly about a prescription baldness medication they say has left them impotent, even years after they stopped taking it.
Sean Ramsaran, 26, was prescribed Propecia by his dermatologist in 2009…and now calls himself ‘a useless person…I have nightmares, flashbacks to experiences I had while on the drug.’
'[Merck] acted responsibly and appropriately with respect to Propecia and Proscar throughout the development, marketing and post-marketing monitoring of these medicines,' wrote spokeswoman Lainie Keller in an email. She added there is no scientific data showing the drugs cause persistent impotence after discontinuing use.

Are Hair-Loss Drugs Safe?
Since 2011, 1,245 lawsuits have been filed against Propecia's manufacturer, Merck, alleging that the company failed to warn users of a constellation of sexual and cognitive side effects — which patients and physicians call Post-Finasteride Syndrome... This spring, the National Institutes of Health added PFS to its rare-diseases database. And in March, a California woman filed the first wrongful death suit against Merck.
Merck said the company "stands behind the demonstrated safety and efficacy profile of Propecia." In recent years, it also added depression and persistent sexual problems to its list of possible side effects, deep in the fine print. It intends to defend itself vigorously when the first cases go to court, likely in 2016. The company will undoubtedly argue that millions use Propecia without harm, and that serious problems are rare. Not rare enough, says Steven Rossello, a 32-year-old who filed the first suit against Merck, in 2011.

Finasteride, the Controversial Drug that Medical Authorities Continue to Defend
English translation here: Part 2
In June 2016, 25-year-old Romain took his life. According to his family, his death can be blamed on post-finasteride syndrome. Finasteride is sold by Merck & Co., which may now be subject to civil or criminal prosecution in France.
[F]inasteride trials using a control group were at first limited to a duration of one year, which was then extended for another year–but only for certain patients: those who were healthy. So these trials…all had one failing: they included people in good health and avoided the inclusion of other categories of patients.”

A Pill the Doctor Gave Me Destroyed My Life. Patients are now filing lawsuits against the pharmaceutical company
English translation here
| The night Thorben Weber lost his manhood ended with, paradoxically, a stunning sunrise in front of his bedroom window. It was July 2015 when he drew his curtains open and looked out at the gently rolling hills of the Black Forest. His body looked the same as always. But nothing worked like it used to. In the ensuing weeks, Weber lost his girlfriend, his apartment and his self-respect.
Neurologists, urologists, dermatologists…they all said Weber was just imagining the discomfort. It took weeks before a professor of andrology at Münster University…made a diagnosis that could explain all the symptoms. ‘You have the Post-Finasteride Syndrome,’ said Michael Zitzmann.

Finasteride Was Once Considered a Miracle Cure for Hair Loss. Now It’s Going to Court
English translation here
A pill has destroyed Thomas Meier. It’s small, it’s pink and it was supposed to help him with something silly: hair loss…His hair got a little bit thicker, but unpleasant things started happening. ‘I was having erectile problems’ [he] explained. Later on, this was followed by loss of libido, depression and panic attacks.
According to one [study], finasteride users were three times more prone to develop mental health problems than men in the control group… In July 2018 the manufacturers ultimately added to the leaflets that the sexual side effects were nonreversible… And yet the medicine is still on the market.

Court Let Merck Hide Cecrets About a Popular Drug’s Risks
On the morning of March 5, 2013, about 45 minutes before his wife got home, John Pfaff stepped onto the railroad tracks a block away and into the path of a southbound Amtrak train. He was killed on impact. Kelly Pfaff blames Merck for her husband’s death at age 40. In a lawsuit filed in 2015, she alleges that the pharmaceuticals company for years knew but concealed from the public that Propecia could cause the persistent sexual dysfunction and depression that led to her husband’s suicide.
[C]onfidential documents reviewed by Reuters accuse Merck of exaggerating the drug’s safety record… [They] allege that in revisions to the drug’s original 1997 label, Merck understated the number of men who experienced sexual symptoms in clinical trials, and how long those symptoms lasted.

Judge Orders Merck Documents on Anti-baldness Drug Propecia Unsealed
A US judge granted a Reuters request to unseal Merck & Co. documents produced in lawsuits related to its anti-baldness treatment Propecia, finding that the public’s right to access outweighed the drug maker’s arguments for keeping the information secret.
[P]laintiffs’ lawyers cited internal company communications to allege that in revisions to the drug’s original label, Merck understated the number of men who experienced sexual symptoms in clinical trials and how long those symptoms lasted. Merck settled before responding to the allegations in court. ‘Merck’s arguments for keeping the documents sealed,’ [Judge Peggy] Kuo wrote, ‘are so weak that they would not overcome even a low presumption of access under the common law.’

Exclusive: Merck Anti-baldness Drug Propecia Has Long Trail of Suicide Reports, Records Show
Newly unsealed court documents and other records show that Merck & Co and US regulators knew about reports of suicidal behavior in men taking the company’s anti-baldness treatment Propecia when they decided not to warn consumers of those potential risks in a 2011 update of the popular drug’s label.
Since…2011…the FDA has received more than 700 reports of suicide and suicidal thoughts among people taking Propecia or generic versions… Those included at least 100 deaths. [I]n the first 14 years the drug was on the market, the agency received 34 such reports, including 10 deaths… To this day, the US label contains no mention of suicide or suicidal thoughts.

A young man who claimed to be depressed after taking a hair loss tablet for five years killed himself by jumping off a bridge, an inquest heard. Jack Hogg, 24, from Exeter, Devon, was not losing his hair but had been self medicating with finasteride. In the months before his death he became concerned about its side effects including depression.
The inquest heard Jack had researched post-finasteride syndrome online which gave a very bleak outlook and led him to believe he had ruined his life. He died from multiple injuries in the fall from 24 metres from the road bridge.
