This medication is used to treat male pattern baldness
(androgenetic alopecia) at the crown and in the middle of the scalp. It
should be used by adult men only.
This medication works by decreasing the amount of a
natural body hormone (DHT). Decreasing the amount of DHT leads to increased
hair regrowth and slower hair loss. Hair growth on other parts of the body
is not affected by finasteride.
Women and children should not use this
medication.
Finasteride is not approved for prevention of prostate
cancer. It may slightly increase the risk of developing a very serious form
of prostate cancer. Talk to your doctor about the benefits and
risks.
Read the Patient Information Leaflet if available from
your pharmacist before you start taking finasteride and each time you get a
refill. If you have any questions, ask your doctor or
pharmacist.
Take this medication by mouth with or without food as
directed by your doctor, usually once a day.
Since this drug can be absorbed through the skin and
lungs and may harm an unborn baby, women who are pregnant or who may become
pregnant should not handle this medication or breathe the dust from the
tablets. It may cause abnormal sex organ development in an unborn male
infant.
Use this medication regularly to get the most benefit
from it. Remember to use it at the same time each day. It may take up to 3
months to notice a benefit.
You must continue to take this medication to maintain
your hair growth. When you stop taking finasteride, any gain in hair
quantity is generally lost within 12 months.
Tell your doctor if your condition does not get better
or if it gets worse.
Decreased sexual ability/desire may occur. In some men,
this medication can decrease the amount of semen released during sex. This
is harmless, but has continued in some men even after stopping treatment.
If any of these effects last or get worse, tell your doctor or pharmacist
promptly.
Remember that this medication has been prescribed
