What the medication is used for

AURO-DUTASTERIDE is used alone (monotherapy) in the treatment of symptomatic benign prostatic hyperplasia (BPH) in men with enlarged prostates.

AURO-DUTASTERIDE is also used in combination with the alpha blocker, tamsulosin, in the treatment of moderate to severe symptomatic BPH in men with enlarged prostates. Combination therapy was also shown to be better than tamsulosin, but not AURO-DUTASTERIDE at reducing the risk of acute urinary retention (or where patient suddenly cannot urinate at all) and/or the need for BPH related surgery.

AURO-DUTASTERIDE is not approved for use in the prevention of prostate cancer.

What it does

Prostate growth is caused by a hormone in the blood called dihydrotestosterone (DHT). AURO-DUTASTERIDE belongs to a group of medicines called 5 alpha-reductase enzyme inhibitors. AURO-DUTASTERIDE lowers DHT production in the body, leading to a shrinkage of the enlarged prostate in most men, which leads to improvements in BPH symptoms and improved urinary flow, reduced risk of acute urinary retention (or where patient suddenly cannot urinate at all), and reduced risk of the need for BPH related surgery.

AURO-DUTASTERIDE is also used with another medicine called tamsulosin, an alpha blocker, which acts by relaxing smooth muscle in the prostate and bladder neck at the site of obstruction, resulting in improvements in BPH symptoms and improved urinary flow.

Symptoms of BPH may be seen to improve after 3 months of treatment with AURO-DUTASTERIDE however, it may take up to 6 months to know if treatment with AURO-DUTASTERIDE will be beneficial.

Warnings and precautions

Serious Warnings and Precautions

  • AURO-DUTAS TERIDE is for use by men only
  • Women who are pregnant, or who may become pregnant, should not handle AURO-DUTASTERIDE as it may pass through the skin. AURO-DUTASTERIDE may affect the normal development of the external genital organs in a male baby.

Heart failure (the heart does not pump blood as well as it should) was reported more often in patients taking dutasteride and an alpha-blocker, tamsulosin, in clinical studies than in patients taking dutasteride. It is not known if taking AURO-DUTASTERIDE and an alpha-blocker caused heart failure.

BEFORE you use AURO-DUTASTERIDE, talk to your doctor or pharmacist if:

  • You have or have had liver problems.
  • You have or have had prostate cancer or urinary tract disease.

What are the special precautions about AURO-DUTASTERIDE?

  • Do not donate blood while taking AURO-DUTASTERIDE and for at least 6 months after you have stopped taking AURO-DUTASTERIDE in order to prevent giving AURO-DUTASTERIDE to a pregnant woman through blood transfusion. • In a clinical study of men aged 50 to 75 years with a recent negative biopsy for prostate cancer and an increased prostate specific antigen (PSA) blood test, men taking AURO-DUTASTERIDE had a serious form of prostate cancer more often than men who did not take AURO-DUTASTERIDE.

You must see your doctor regularly. While taking AURO-DUTASTERIDE, you must have regular checkups, including digital rectal examination and PSA examination. Follow your doctor’s advice about when to have these checkups.

Checking for prostate cancer
A man can have BPH and prostate cancer at the same time. Prior to treatment with AURO-DUTASTERIDE, you should have a thorough urological evaluation to determine the severity of your condition, and to rule out the need for immediate surgery or the possibility of prostate cancer.

About Prostate Specific Antigen (PSA)
If a doctor asks you to have a Prostate Specific Antigen (PSA) test which is used for screening prostate cancer, you should tell your doctor that you are taking AURO-DUTASTERIDE. AURO-DUTASTERIDE can lower the PSA test result. A low PSA level may give you a false sense of security about your risk for prostate cancer. Your doctor is aware of this effect and can still use PSA to see if you might have prostate cancer. Increases in your PSA levels while on treatment with AURO-DUTASTERIDE (even if the PSA levels are in the normal range) should be evaluated by your doctor.
