Propecia, a pill taken by mouth is a new and effective treatment for male pattern baldness. A net increase in scalp hair count and hair regrowth was seen in over 80% of men for whom it was prescribed. Improvements were seen as quickly as 3 months after starting the medicine. PROPECIA not only led to a decrease in hair loss but also significantly increased the rate of hair regrowth. These effects were maintained for over 2 years with continued PROPECIA therapy. It was concluded from these studies that as long as PROPECIA therapy is continued it will remain effective in facilitating hair regrowth.

This drug is taken by mouth. 1 tablet per day. PROPECIA is the brand name for finasteride, which acts to inhibit the conversion of the androgen (male hormone) testosterone into 5-alpha-dihydrotesterone (DHT). In men each hair follicle contains tiny amounts of DHT. As male pattern baldness begins the amount of DHT contained in each follicle increases. PROPECIA through its inhibitory action serves to reverse this process by decreasing the amount of DHT in the hair follicle and in blood.

In multiple clinical studies adverse reactions were noted to be rare and did not affect most men. The most common adverse reaction was decreased libido that appeared to occur in less then 2.0% of men taking this medicine. The problem quickly resolved in all cases upon the discontinuation of the medication.

PROPECIA does not appear too have any significant interactions with other drugs taken concomitantly. PROPECIA tablets are film coated, however a crushed or broken tablet should not be handled by women who are pregnant or who may be pregnant due to potential adverse effects of this medication on the male fetus. Caution should be used when men with liver disorders take PROPECIA. This medicine is broken down by liver-enzymes. Therefore, in patients with liver disease, PROPECIA can cause hepatitis (liver inflammation), although this problem is seen very rarely.
