PROSCAR is for use by men only.
Please read this leaflet before you start taking PROSCAR. Also, read it each time you renew your
prescription, just in case anything has changed. Remember, this leaflet does not take the place of careful
discussions with your doctor. You and your doctor should discuss PROSCAR when you start taking your
medication and at regular checkups.
What is PROSCAR?
PROSCAR is a medication used to treat symptoms of benign prostatic hyperplasia (BPH) in men with an
enlarged prostate. PROSCAR may also be used to reduce the risk of a sudden inability to pass urine and
the need for surgery related to BPH in men with an enlarged prostate.
PROSCAR may be prescribed along with another medicine, an alpha-blocker called doxazosin, to help
you better manage your BPH symptoms.
Who should NOT take PROSCAR?
PROSCAR is for use by MEN only.
Do Not Take PROSCAR if you are:
• a woman who is pregnant or may potentially be pregnant. PROSCAR may harm your unborn
baby. Do not touch or handle crushed or broken PROSCAR tablets (see “A warning about
PROSCAR and pregnancy”).
• allergic to finasteride or any of the ingredients in PROSCAR. See the end of this leaflet for a
complete list of ingredients in PROSCAR.
A warning about PROSCAR and pregnancy:
Women who are or may potentially be pregnant must not use PROSCAR. They should also not handle
crushed or broken tablets of PROSCAR. PROSCAR tablets are coated and will prevent contact with the
active ingredient during normal handling, provided that the tablets are not broken or crushed.
If a woman who is pregnant with a male baby absorbs the active ingredient in PROSCAR after oral use or
through the skin, it may cause the male baby to be born with abnormalities of the sex organs. If a woman
who is pregnant comes into contact with the active ingredient in PROSCAR, a doctor should be consulted.
How should I take PROSCAR?
Follow your doctor’s instruction.
• Take one tablet by mouth each day. To avoid forgetting to take PROSCAR, you can take it at the
same time every day.
• If you forget to take PROSCAR, do not take an extra tablet. Just take the next tablet as usual.
• You may take PROSCAR with or without food.
• Do not share PROSCAR with anyone else; it was prescribed only for you.
What are the possible side effects of PROSCAR?
PROSCAR may increase the chance of a more serious form of prostate cancer.
The most common side effects of PROSCAR include:
• trouble getting or keeping an erection (impotence)
• decrease in sex drive
• decreased volume of ejaculate
• ejaculation disorders
• enlarged or painful breast. You should promptly report to your doctor any changes in your breasts
such as lumps, pain or nipple discharge.
The following have been reported in general use with PROSCAR and/or finasteride at lower doses:
• allergic reactions, including rash, itching, hives, and swelling of the lips, tongue, throat, and face
• rarely, some men may have testicular pain
• trouble getting or keeping an erection that continued after stopping the medication
• problems with ejaculation that continued after stopping the medication
• male infertility and/or poor quality of semen. Improvement in the quality of semen has been
reported after stopping the medication.
• decrease in sex drive that continued after stopping the medication
• in rare cases, male breast cancer has been reported.
You should discuss side effects with your doctor before taking PROSCAR and anytime you think you are
having a side effect. These are not all the possible side effects with PROSCAR. For more information, ask
your doctor or pharmacist.
Call your doctor for medical advice about side effects. You may report side effects to FDA at: 1-800-FDA1088.
What you need to know while taking PROSCAR:
• You should see your doctor regularly while taking PROSCAR. Follow your doctor’s advice
about when to have these checkups.
• Checking for prostate cancer. Your doctor has prescribed PROSCAR for BPH and not for
treatment of prostate cancer — but a man can have BPH and prostate cancer at the same time.
Your doctor may continue checking for prostate cancer while you take PROSCAR.
• About Prostate-Specific Antigen (PSA). Your doctor may have done a blood test called PSA for
the screening of prostate cancer. Because PROSCAR decreases PSA levels, you should tell your
doctor(s) that you are taking PROSCAR. Changes in PSA levels will need to be evaluated by your
doctor(s). Any increase in follow-up PSA levels from their lowest point may signal the presence of
prostate cancer and should be evaluated, even if the test results are still within the normal range.
You should also tell your doctor if you have not been taking PROSCAR as prescribed because
this may affect the PSA test results. For more information, talk to your doctor.
How should I store PROSCAR?
• Store PROSCAR tablets in a dry place at room temperature.
• Keep PROSCAR in the original container and keep the container closed.
PROSCAR tablets are coated and will prevent contact with the active ingredient during
normal handling, provided that the tablets are not broken or crushed.
Keep PROSCAR and all medications out of the reach of children.
Do not give your PROSCAR tablets to anyone else. It has been prescribed only for you.

What is BPH?
BPH is an enlargement of the prostate gland. The prostate is located below the bladder. As the prostate
enlarges, it may slowly restrict the flow of urine. This can lead to symptoms such as:
• a weak or interrupted urinary stream
• a feeling that you cannot empty your bladder completely
• a feeling of delay or hesitation when you start to urinate
• a need to urinate often, especially at night
• a feeling that you must urinate right away.
In some men, BPH can lead to serious problems, including urinary tract infections, a sudden inability to
pass urine (acute urinary retention), as well as the need for surgery.
What PROSCAR does:
PROSCAR lowers levels of a hormone called DHT (dihydrotestosterone), which is a cause of prostate
growth. Lowering DHT leads to shrinkage of the enlarged prostate gland in most men. This can lead to
gradual improvement in urine flow and symptoms over the next several months. PROSCAR will help
reduce the risk of developing a sudden inability to pass urine and the need for surgery related to an
enlarged prostate. However, since each case of BPH is different, you should know that:
• Even though the prostate shrinks, you may NOT notice an improvement in urine flow or
• You may need to take PROSCAR for six (6) months or more to see whether it improves your
• Therapy with PROSCAR may reduce your risk for a sudden inability to pass urine and the need
for surgery for an enlarged prostate
