Answers to Frequently Asked Questions about Propecia lawsuits

What is Propecia?

Propecia is a drug containing the active ingredient finasteride, sold as a treatment for androgenic alopecia, also known as male pattern baldness, which is characterized as hair loss in men. Propecia belongs to a class of prescription medicines known as 5-alpha-reductase inhibitors.

Propecia (finasteride 1mg) was approved by the FDA in 1997 as a prescription drug for the treatment of male pattern baldness.

The precursor of Propecia is Proscar (finasteride 5mg) which contained five times the active ingredient found in Propecia and is aimed at curing the symptoms of benign prostatic hyperplasia also know as BPH or enlarged prostate. Proscar was approved by the FDA in 1992.


Why are lawsuits being filed against the manufacturer of Propecia?

The primary reason why people have filed lawsuits against Merck is because of injuries resulting from usage of the drug. Plaintiffs claim that the manufacturer:

  • Failed to take “reasonable care” in designing, testing and bringing the drug to market.
  • Knew or should have known that Propecia increases the risk of persistent and permanent side effects, even after discontinuing use of the drug.
  • Failed to provide proper warnings and even concealed known risks from consumers and doctors.
  • Had misled customers by not disclosing the sexual side effects prior to April 2011 (the FDA had enforced a revision afterwards which cautioned of “libido disorders, ejaculation disorders, and orgasm disorders that continued after discontinuation of the drug”)
  • Knew that the public and scientific community would rely on the medication’s label and the “the presumption that the dangers did not exist,” yet sold the drug without the necessary warnings.

What side effects have been linked to Propecia?

The following serious side effects have been observed in patients who were prescribed Propecia:

  • Gynecomastia (swelling of breasts in males)
  • Erectile dysfunction
  • Impotence
  • Genital shrinkage
  • Penile fibrosis (Peyronie’s disease)
  • Decreased libido (less desire for sex)
  • Ejaculation disorders
  • Decrease in the amount of semen
  • Body disfigurement
  • Endocrine system failure
  • Male breast cancer
  • Testicular pain
  • Breast lumps
  • Breast pain
  • Nipple discharge
  • Prostate cancer
  • Depression
  • Anxiety
  • Insomnia
  • Memory loss
  • Slurred speech
  • Disassociative states (haziness, dullness)


It should be noted that the causal links between Propecia and sexual dysfunction have not been established scientifically however the numerous reports coming from patients suggest a wider range of adverse effects than previously reported by the manufacturer. This warrants further investigation.

Do the side effects of Propecia not subside once you stop taking the drug?

Although the Propecia label says that male infertility and/or semen quality should normalize or improve after drug discontinuation, a 2003 study concluded that sexual dysfunction was solved only in 50% of the patients who discontinued use of Propecia. In addition to this,  in 2011, both Propecia and Proscar’s labels were revised to include erectile dysfunction that persisted after drug discontinuation.

I am currently taking Propecia. What should I do?

If you are currently taking Propecia and you are worried or have questions about the drug’s side effects, do not stop using the drug without consulting with your health care professional first. If you have suffered any of the more serious side effects and have a persistent and permanent injury as a result of using Propecia, call us or fill in the online form to see if you can file a Propecia lawsuit.

What do I have to gain from filing a lawsuit against the manufacturer of Propecia?

Those who have been affected by Propecia experience sexual dysfunction and cognitive impairment. This can be a great cause of trouble not only physically but also emotionally. Some men report having anxiety attacks and depression as a result of their impaired sexual function. The harm caused by this drug may be irreversible and deadly. By filing a lawsuit against the pharmaceutical company that manufactures Propecia, you have a change of obtaining relief and financial compensation for:

  • Current and future medical expenses
  • Home health care
  • Lost income
  • Persistent side effects and permanent disability
  • Pain and suffering


When applicable, a lawsuit allows you to seek punitive damages which deter a manufacturer from future reckless behavior. By suing Big Pharma for dangerous medication that was not properly tested, you have a chance of preventing others in repeating the same fate. Unfortunately, drug manufacturers have to be brought to justice before they change their behavior as their primary incentive is financial gain with health and moral implications being second.
