Propecia contains a medicine called finasteride. This belongs to a group of medicines called Type II ‘5-alpha reductase inhibitors’.
Propecia is used for the treatment of male pattern hair loss (also known as androgenetic alopecia). Propecia increases hair growth on the scalp and prevents further hair loss in men. Men with mild to moderate, but not complete hair loss, can benefit from using Propecia.
On average your hair grows about 1 centimetre (half an inch) each month. Hair grows from hair follicles, which are located under your skin.
A single scalp hair grows continuously for 2-4 years (growth phase) and then stops growing for 2-4 months (rest phase). After this the hair falls out. In its place a new healthy hair begins to grow, and the cycle is repeated. The hairs on your scalp are always in different stages of this cycle so it is normal to lose scalp hair every day.
Male pattern hair loss is a common condition in which men experience thinning of the hair on the scalp, often resulting in a receding hairline and/or balding on the top of the head. This condition is thought to be caused by a combination of genetic factors and a particular hormone, DHT (dihydrotestosterone).
DHT causes a decrease in the growth phase and thinning of the hair (see picture). This leads to male pattern hair loss. These changes can start to occur in some men in their 20s and become more common with age. Once hair loss has occurred over a long period of time, the hair may be permanently lost.
Propecia lowers the levels of DHT in the scalp. This helps to reverse the balding process, leading to an increased hair growth and prevention of further hair loss.
Do not take Propecia if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist.
Talk to your doctor or pharmacist before taking Propecia if:
Infertility has been reported in men who took finasteride for a long time and had other risk factors that may affect fertility. Normalisation or improvement of seminal quality has been reported after discontinuation of finasteride. Long-term clinical studies about the effects of finasteride on fertility in men have not been conducted.
See section 4.
Mood alterations such as depressed mood, depression and, less frequently, suicidal thoughts have been reported in patients treated with Propecia. If you experience any of these symptoms stop taking Propecia and contact your doctor for further medical advice as soon as possible.
Propecia should not be used in children. There are no data demonstrating efficacy or safety of finasteride in children under the age of 18.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Propecia does not usually affect other medicines.
