Where is Finasteride used?

Finasteride is used for the treatment of an enlarged prostate gland called benign prostatic hyperplasia (BPH). This is in the class of medications called 5-alpha reductase inhibitors that decrease the amount of the hormone dihydrotestosterone (DHT) in your body. DHT usually causes your prostate to develop larger. Low levels of DHT help prevent your prostate from developing larger.

This medication may also be used for the treatment of male pattern hair loss. Finasteride blocks the body’s production of a male hormone in the scalp that stops the growth of the hair.

How does Finasteride work?

Finasteride works by blocking the action of an enzyme in the body called 5-alpha reductase. This enzyme is called DHT which is responsible for converting the male hormone testosterone into a more active form. Enlargement of the prostate gland is dependent upon testosterone being converted to DHT within the prostate gland. By blocking 5-alpha reductase, this medicine prevents the formation of DHT and this helps shrink the prostate.

How is Finasteride taken?

The recommended dosage is based on your medical condition, age, and response to the treatment. This is to be taken by mouth usually once a day or as directed by your doctor. It may take 6 to 12 months to notice a benefit. You may take each dose with or without a meal. Swallow the tablet as a whole with a full glass of water. Do not break, chew, or crush it. Drink plenty of fluids while having this medication. Doing so may lessen the risk of certain side effects. Remember to take it at the same time and in the same way each day.
