What Dutasteride is and what it is used for
The active ingredient is dutasteride. It belongs to a group of medicines called 5-alpha reductase
Dutasteride is used to treat men with an enlarged prostate (benign prostatic hyperplasia) - a noncancerous growth of the prostate gland, caused by producing too much of a hormone called
As the prostate grows, it can lead to urinary problems, such as difficulty in passing urine and a need to
go to the toilet frequently. It can also cause the flow of the urine to be slower and less forceful. If left
untreated, there is a risk that your urine flow will be completely blocked (acute urinary retention). This
requires immediate medical treatment. In some situations surgery is necessary to remove or reduce
the size of the prostate gland. Dutasteride lowers the production of dihydrotestosterone, which helps to
shrink the prostate and relieve the symptoms. This will reduce the risk of acute urinary retention and
the need for surgery.
Dutasteride may also be used with another medicine called tamsulosin (used to treat the symptoms of
an enlarged prostate).
What you need to know before you take Dutasteride

are allergic to dutasteride, other 5-alpha reductase inhibitors, soya, peanuts or to any of the other
ingredients of this medicine (listed in section 6)

Tell your doctor if you think any of these apply to you.
This medicine is for men only. It must not be taken by women, children or adolescents.
Warnings and precautions

alpha blocker. Heart failure means your heart does not pump blood as well as it should

your liver, you may need some additional check-ups while you are taking Dutasteride

Dutasteride affects a blood test for PSA (prostate-specific antigen), which is sometimes used to
detect prostate cancer. Your doctor should be aware of this effect and can still use the test to detect
prostate cancer. If you are having a blood test for PSA, tell your doctor that you are taking
Dutasteride. Men taking dutasteride should have their PSA tested regularly. In a clinical study of
men at increased risk of prostate cancer, men taking dutasteride had a serious form of prostate
cancer more often than men who did not take dutasteride. The effect of dutasteride on this serious
form of prostate cancer is not clear
