What FINASTERIDE-1MG is used for
FINASTERIDE-1MG is for use by men only.
FINASTERIDE-1MG is used to treat men with male pattern hair loss to increase hair
growth on the scalp and to prevent further hair loss.
Male pattern hair loss (also known as androgenetic alopecia) is a common condition
in which men experience thinning of the hair on the scalp. This often results in a
receding hair line and/or balding on the top of the head. These changes typically
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.
Male pattern hair loss is thought to be caused by a combination of family history
(heredity) and production of a particular male hormone, called dihydrotestosterone
(DHT). Men with male pattern hair loss have more DHT in the balding part of their
scalp than in other parts, resulting in increased hair loss.
How FINASTERIDE-1MG works
FINASTERIDE-1MG specifically lowers the levels of DHT in the scalp, thus helping to
reverse the balding process.
FINASTERIDE-1MG does not affect hair on other parts of the body.
Men with mild to moderate, but not complete, hair loss can expect to benefit from
the use of FINASTERIDE-1MG. In women who were studied, FINASTERIDE-1MG was not effective
in the treatment of hair loss (androgenetic alopecia).
There should be no need to change your usual hair care routine (for example, shampooing
or haircuts) because you are taking FINASTERIDE-1MG.
FINASTERIDE-1MG is not addictive.

FINASTERIDE-1MG helps most men with male pattern hair loss, but it may have unwanted
side effects in a few men. All medicines can have side effects. Sometimes they are
serious, most of the time they are not. You may need medical treatment if you get
some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
difficulty in achieving an erection that continues after stopping FINASTERIDE-1MG
less desire for sex that continued after stopping FINASTERIDE-1MG
decreased amount of semen released during sex (this decrease does not appear to interfere
with normal sexual function).
It is important to understand that, in clinical trials, these unwanted effects disappeared
in men who stopped taking FINASTERIDE-1MG, as well as in many men who continued treatment.
Problems with ejaculation that continue after stopping medication have been reported
infrequently. Tell your doctor if you notice this and it worries you.
Male infertility and/or poor quality of semen have been reported infrequently. Improvement
in the quality of semen has been reported after stopping FINASTERIDE-1MG.
Tell your doctor immediately if you notice any of the following:
breast swelling and/or tenderness
In rare cases, male breast cancer has been reported.
breast lumps, pain or discharge from the nipples.
skin rash, itchiness
hives or nettlerash (pinkish, itchy swellings on the skin)
blood in semen
depressions (feelings of severe sadness and unworthiness) including suicidal thoughts
These are uncommon side effects that have been reported with FINASTERIDE-1MG.
Tell your doctor immediately or go to accident and emergency at your nearest hospital
if the following happens:
swelling of the lips, tongue, throat or face
These may be symptoms of a serious allergic reaction to FINASTERIDE-1MG, which may
cause difficulty in swallowing or breathing. You may need urgent medical attention.
Serious side effects are rare.
Other side effects not listed above may occur in some men. Tell your doctor or pharmacist
if you notice any other unwanted effects.
