A dose of Proscar, used to reduce symptoms of enlarged prostate (benign prostatic hyperplasia or BPH), has five times more finasteride than a dose of Propecia, used to reduce male pattern hair loss. " April 13, 2012 -- The baldness drug Propecia and the BPH drug Proscar may cause infertility and more sexual problems than previously thought, the FDA warns. Both drugs are known to cause erectile dysfunction in some men. Now labels on both drugs will include new warnings: There's no definitive proof that either Propecia or Proscar actually causes these problems. But the FDA has received enough reports of these side effects to cause concern. Even if the drugs do cause these sexual side effects, they've been reported in only a small number of men. For example, in Propecia clinical trials, 3.8% of men taking the drug and 2.1% of men getting an inactive placebo reported sexual problems. Moreover, the warnings are based on relatively small numbers of reported problems. zithromax side effects in children Along with its needed effects, finasteride (the active ingredient contained in Propecia) may cause some unwanted effects.

There are a number of side effects associated with this medication, although new studies suggest. Finasteride, a hair-loss medication reportedly used by footballer Wayne Rooney, 'could cause permanent impotence and shrink genitals in some men' says the Daily Mail. The first is a US TV interview with a man who claimed his genitals shrunk after taking Propecia (finasteride), a drug used to treat male pattern baldness. The second, more verifiable source, is a study that found that finasteride could cause persistent loss of libido and erectile dysfunction. There are a number of significant concerns with both sources. Firstly, there is no hard evidence to back the claims of the man who was interviewed. And the second study included only a very small sample of men, all of whom were experiencing persistent sexual problems, and who were recruited via a website that was set up by men who claimed that finasteride had caused them sexual side effects. This may not necessarily reflect the experiences of all men who take finasteride. While the manufacturers of Propecia concede that loss of libido and erectile dyfunction are known side effects of the drug, they report that these types of side effects are uncommon (clinical trials have observed frequency of 1.8% for loss of libido and 1.3% for erectile dysfunction). Finasteride is used to treat men with benign prostatic hyperplasia (BPH) and male pattern hair loss, also called androgenetic alopecia. Men with BPH usually have difficulty urinating, a decreased flow of urination, hesitation at the beginning of urination, and a need to get up at night to urinate. Finasteride will make these symptoms less severe and reduce the chance that prostate surgery will be needed. It may be used alone or in combination with other medicines such as an alpha-blocker (doxazosin, Cardura®) to treat BPH. For men with hair loss, finasteride will increase the number of scalp hairs but will not increase the amount of body hair. Finasteride blocks the action of an enzyme called 5-alpha-reductase. This enzyme changes testosterone to another hormone that causes the prostate to grow or hair loss in males. It will increase testosterone levels in the body, which decreases prostate size and increases hair growth on the scalp.
