How does this medication work? What will it do for me?
Dutasteride belongs to a class of medications known as 5-alpha-reductase inhibitors. It is used to relieve symptoms of benign prostatic hyperplasia (BPH) for people with enlarged prostates. BPH is a noncancerous enlargement of the prostate gland that usually happens 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
Dutasteride may be prescribed along with another medication called tamsulosin in order to decrease the symptoms of BPH.
It may take 6 months or more to see the full effects of this medication. Dutasteride reduces the likelihood of prostate surgery for people 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.

Are there any other precautions or warnings for this medication?
Before you begin taking a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should take this medication.
Blood donation: People taking this medication should not donate blood until at least 6 months have passed following their last dose. This is to prevent pregnant people from being exposed to dutasteride during a blood transfusion.
Liver disease: If you have liver disease or decreased liver function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Prostate cancer: Dutasteride may be linked to an increased risk of developing a rare type of cancer called high-grade prostate cancer. The risk of developing this cancer while taking this medication is still considered very small. Note that dutasteride is not approved to treat prostate cancer. If you experience worsening symptoms or symptoms that do not improve within 6 months, discuss this with your doctor.
PSA test: Dutasteride can decrease PSA (prostate specific antigen) levels by up to 50%. Doctors often measure PSA levels to test for prostate cancer. PSA levels can still be measured for this purpose, but your doctor will need to adjust the results in order for the test to be accurate. If you are having a PSA test, ensure your doctor knows that you are taking dutasteride.
People who could become pregnant and children: Dutasteride is intended for use by people with a prostate only. People who are pregnant, people who could become pregnant, and children must avoid contact with the medication, as it is absorbed through the skin. If contact occurs, wash the exposed area immediately with soap and water.
Pregnancy: This medication is intended for use by people with a prostate only. People who may be pregnant must avoid touching any pills of dutasteride (even ones that are not leaking). Pregnant people or people who may be pregnant should not handle dutasteride because the medication can be absorbed through the skin and may cause abnormalities in the baby. If you are pregnant and accidentally come into contact with the capsules, wash the contact area immediately with soap and water.
Breast-feeding: It is not known if dutasteride passes into breast milk. Do not handle this medication if you are breast-feeding because the medication can be absorbed through the skin and may affect the baby.
Children: This medication is not intended for use by children. The safety and effectiveness of dutasteride have not been established for use by people in this age group.
