Drug Name

Proscar (Finasteride)

Drug Uses

Proscar is used for treating benign prostatic hyperplasia (BPH), which is enlargement of the prostate gland and reducing symptoms, including a weak or interrupted urinary stream, feeling that you cannot empty your bladder completely, delay or hesitation when you start to urinate, frequent urination especially at night, feeling that you must urinate right away; reducing the risk of developing a sudden inability to pass urine; and reducing the need for surgery.

How Taken

Use Proscar as directed by your doctor.

• Proscar may be taken with or without food.
• Continue to use Proscar even if you feel well. Do not miss any doses.
• Using Proscar at the same time each day will help you to remember.

Drug Class and Mechanism

Proscar is an enzyme inhibitor. It works by lowering levels of a hormone called DHT (dihydrotestosterone), which is a major cause of prostate growth; lowering DHT leads to shrinkage of the enlarged prostate gland.

Missed Dose

If you miss a dose of Proscar , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Storage
