Pill Name

Proscar (Finasteride)

Pill Uses

Proscar prevents the conversion of testosterone to dihydrotestosterone (DHT) in the body. DHT is involved in the development of benign prostatic hyperplasia (BPH).

Proscar is used to treat symptoms of benign prostatic hyperplasia (BPH) in men with an enlarged prostate.

Proscar may also be used for other purposes not listed in this medication guide.

How Taken Drug

Use Proscar as directed by your doctor.

• The recommended dosage, for men only, is one 5-milligram tablet per day.
• You may take Proscar either with a meal or between meals.
• 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.

Ask your health care provider any questions you may have about how to use Proscar.

Drug Class and Mechanism Action

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 Drug

Take the missed dose as soon as you remember. However, if it is almost time for your next dose, skip the dose you missed and take only your next regularly scheduled dose. Do not take a double dose of this medication.

Storage Drug

Store Proscar at room temperature, below 86 degrees F (30 degrees C). Store away from heat, moisture, and light. Do not store in the bathroom. Keep Proscar out of the reach of children and away from pets.
