Now you will have to decide as to what is more important for you. FDA says hair loss treatment drug Propecia may cause sexual problems in men

Hair loss or baldness is a common problem these days. People suffering from these problems always try to overcome it, but it is hard to believe that the medicines prescribed for baldness may cause sexual problems. Here is a case of one drug called Finasteride. Its brand name is Propecia and Proscar. With the name of proscar it is used to treat benign prostate hypertrophy (BPH) and with the name of Propecia it is used to treat baldness.

Propecia was approved by US food and drug administration (FDA) in 1997 and Proscar was approved in 1992 by the same authority. Propecia is used widely by Americans for baldness and in some users it caused decreased libido and in some users it caused male infertility and poor semen quality. When they stopped taking the drug the symptoms improved, but in some cases the symptoms remained for more than three months after stopping the medicine. Now you have to be cautious while taking treatment for baldness or prostate enlargement.

US food and drug administration reviewed 421 reports of sexual dysfunction from 1998 to 2011 reported to Propecia. FDA suggests that in case of Propecia 59 people reported sexual problems, while 131 cases of erectile dysfunction and 68 cases of decreased libido with Proscar were reported from 1992 to 2010. Condition lasted longer than three months after drug discontinuation.

FDA has announced label changes for both drugs, saying they could cause sexual side effects in men who take them.

The drugs are sold by famous company Merck and although FDA has ordered to change the label on both Propecia and Proscar, and has ordered to write warning about sexual problems, still it is not a final result about relation of sexual problems and use of propecia.

Pamela Eisele, a spokeswoman for Merck said in a statement “because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a casual relationship to drug exposure”. She further said “Merck believes that propecia and proscar are generally well tolerated and effective for their prospective indicated use  when used in accordance with their approved labeling”.

    I asked my doctor recently about a Fenasteride article stateing that it might cause cancer with prolonged use and he told me that the pill was safe,now this why are doctors not doing there homework about the effects of these pills do they not care or is getting paid by the company who makes these pills more inportant to them. Someone at the top needs to check these doctors out a least in WA state they do…I have actually over heard a doctor tell a patient not to worry the insurance will foot the bill.
