Finasteride Tablets contain a medicine called finasteride. This belongs to a group of medicines called Type II ‘5-alpha reductase inhibitors’.
Finasteride Tablets are used for the treatment of male pattern hair loss (also known as androgenetic alopecia). Finasteride Tablets increase hair growth on the scalp and prevent further hair loss in men. Men with mild to moderate, but not complete hair loss, can benefit from using Finasteride Tablets.
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.
Finasteride Tablets lower 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.
- are a woman (because this medicine is for men). It has been shown in clinical trials that Finasteride Tablets do not work in women with hair loss.
- are allergic (hypersensitive) to finasteride or any of the other ingredients of this medicine (listed in Section 6).
- are already taking finasteride or dutasteride used for a prostate problem called benign prostatic hyperplasia (BPH).
Do not take Finasteride Tablets 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 Finasteride Tablets if:
- you are going to have a blood test for prostate cancer called PSA (prostate-specific antigen). This is because Finasteride Tablets can affect the result of this test.
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 Finasteride Tablets. If you experience any of these symptoms stop taking Finasteride Tablets and contact your doctor for further medical advice as soon as possible.
Impaired sexual function that may contribute to mood alterations, including suicidal thoughts, has been reported in some patients. If you experience symptoms of impaired sexual function, contact your doctor for further medical advice. Your doctor may consider stopping the treatment (see section 4 below for more information about these side effects).
Impaired sexual function has also been reported without mood alterations or suicidal thoughts.
A patient card reminding of the above is provided with the package of Finasteride tablets

- the number of men who developed prostate cancer was lower in men taking finasteride compared with those taking nothing
- the number of men who had a high score in a tumour grading system was higher in some of those taking finasteride compared to those taking nothing
- the effect of long-term use of finasteride on tumours of this kind is unknown.
