In early 2012, before the Propecia and Proscar Warning Labels were changed to include more information about sexaul side effects, a study published by Venkataram Mysore in Indian Dermatology Online Journal titled “Finasteride and sexual side effects” aimed to further clarify the relationship between finasteride (the active chemical in the the two aforementioned drugs) and long-term sexual side effects.

As such, the author states, “Finasteride, a 5-alpha reductase inhibitor, widely used in the medical management of male pattern hairloss, has been reported to cause sexual side effects. This article critically examines the evidence available and makes recommendations as to how a physician should counsel a patient while prescribing the drug.”

The author explains, “Pattern hair loss in males is androgenic in etiology. Antiandrogens such as finasteride are therefore useful in the management of the condition. Androgens, especially testosterone increases the libido. Any drug which interferes with the action of androgens is therefore assumed, by the lay person, to induce impotence.”

Continuing, it is noted “A number of studies have looked at the problem of side effects caused by finasteride.[6–11] These studies which are discussed below reveal that sexual adverse effects occur at the rates of 2.1% to 3.8%, erectile dysfunction (ED) being the commonest followed by ejaculatory dysfunction and loss of libido. These effects occurred early in the therapy and returned to normal on stopping or over a time on continuous use of the drug. The only causal relation between finasteride and sexual adverse effects is decreased ejaculatory volume because of predominant action of DHT on prostate.”

Due to the fact that a number of people have used Propecia and Proscar (Merck & Co., Inc.) without sufficient knowledge of the possibility of sexual side-effects, a number of Propecia lawsuits and Proscar lawsuits have been filed.  If you or a loved one used one of these drugs and suffered sexual side-effects, you too may be entitled to significant financial compensation.  For a free, no-obligation case consultation, contact our team of Proscar lawyers and Propecia lawyers at the information provided below.  We have the experience, resources, and skills required to win the justice you deserve.
