What this medicine is used for
Finasteride is for use by men only.
Finasteride is used to treat a medical condition in men called benign prostatic hyperplasia
(BPH). BPH is a condition where your prostate gland (which is near your bladder) has
become bigger, making it more difficult for you to pass urine. This can lead to symptoms
weak or interrupted stream of urine
feeling that you cannot empty your bladder completely
a delay before you start to pass urine
needing to pass urine often, especially at night
feeling that you must pass urine right away
BPH occurs only in men and is common over the age of 50 years. The prostate gland
takes years to grow. Therefore, the symptoms of BPH take a long time to develop. In
some men, BPH can lead to serious problems, including urinary tract infections and
the sudden inability to pass urine at all (acute urinary retention). BPH may also
require surgery to improve the flow of urine.
How it works
Finasteride works by slowly reducing the size of your prostate gland. This may lead
to gradual improvement in your urine flow and other symptoms over several months.
Finasteride also helps reduce the risk of developing a sudden inability to pass urine
and the need for surgery. This may happen whether or not you notice any improvement
or change in your symptoms.
