How does this medication work? What will it do for me?
Dutasteride belongs to a class of medications called 5-alpha-reductase inhibitors and is used to relieve symptoms of benign prostatic hyperplasia (BPH) in men with enlarged prostates. BPH is a noncancerous enlargement of the prostate gland that usually occurs in men after the age of 50.
Dutasteride works to reduce the production of dihydrotestosterone (DHT), a hormone that causes enlargement of the prostate gland. Dutasteride relieves symptoms of BPH by reducing the size of the prostate and improving the flow of urine.
This medication improves symptoms associated with BPH, such as:
- decreased urine flow
- difficulty urinating
- getting up to urinate during the night
- hesitation at the start of urination
It may take 6 months or more to see the full effects of this medication. Dutasteride reduces the likelihood of prostate surgery for men with BPH. It must be taken on a regular basis to be effective. If the medication is stopped, the prostate will start to grow again.
