Sexual Side Effect Warnings Added to Propecia, Proscar Labeling

Two popular prescription drugs, Propecia and Proscar, will see additions to their labels warning patients of potential sexual dysfunction side effects that last beyond discontinuation of the drugs. According to Reuters, the Propecia label will warn of problems with libido, ejaculation and orgasms that continued after use of the drug was ended, and Proscar's label will warn of decreased libido. Both drugs already contained warnings of possible erectile dysfunction, which were added by the U.S. Food and Drug Administration (FDA) last year.

Some patients and lawsuits claim that Merck it knew about serious side effects but did nothing to notify consumers about them.

Propecia is a popular drug that combats hair loss and Proscar is a drug commonly prescribed to fight enlarged prostates. Multiple studies have shown adverse sexual side effects with use of the drug finasteride (Proscar and Propecia) and also with dutasteride (Avodart), and more recent research has indicated that these effects may be irreversible. The FDA is changing the current labeling due to widespread reports from patients of the side effects lasting even after discontinuation of use of the drug. These side effects include erectile dysfunction, reduced ejaculation, depression, and loss of libido. The manufacturer of Propecia and Proscar is pharmaceutical giant Merck & Co.

Merck and its drugs have been the source of complaints over sexual dysfunction for quite some time, but especially in the past year. Some patients and lawsuits claim that Merck it knew about serious side effects but did nothing to notify consumers about them. In response to mounting claims against the drug, Merck actually pulled its Propecia website earlier this spring (though it is now back up). The website, www.propecia.com, contained a message saying “You are encouraged to report negative side effects of prescription drugs to the FDA.”

Propecia and Proscar are popular drugs with many benefits, but users and prospective users should consult their doctor and discuss the risks before starting or continuing use. These FDA warnings on the drugs’ labels are a welcome addition, as many users have reportedly experienced serious sexual side effects from use of these drugs.
