Proscar contains a medicine called finasteride. This belongs to a group of medicines called 5 alpha reductase inhibitors. Proscar shrinks the prostate gland in men when it is swollen. The prostate gland is found underneath the bladde (but only in men). It produces the fluid found in semen. A swollen prostate gland can lead to a condition called benign prostatic hyperplasia or BPH. BPH means that your prostate gland is swollen. It can press on the tube that urine passes through on its way out of your body. This can lead to problems such as- feeling like you need to pass urine more often, especially at night, feeling that you must pass urine right away, finding it difficult to start passing urine, when you pass urine the flow of urine is weak, when you pass urine the flow stops & starts, & feeling that you cannot empty your bladder completely. In some men, BPH can lead to more serious problems such as urinary tract infections, a sudden inability to pass urine & the need for surgery.
