7. Product details
1. Why am I using DUTATAM 500/400?
DUTATAM 500/400 contains the active ingredient dutasteride and tamsulosin hydrochloride.
Dutasteride belongs to a group of medicines called 5-alpha reductase enzyme inhibitors and tamsulosin hydrochloride belongs to a group of medicines called alpha-blockers.
DUTATAM 500/400 is used to treat men with benign prostatic hyperplasia (BPH).
BPH is a non-cancerous enlargement of the prostate gland which is located at the lower portion of the urinary bladder surrounding the urethra (urine carrying tube). In men with BPH, the prostate gland becomes large enough to squeeze the urine tube running through it. If this tube is squeezed it narrows, making it more difficult to pass urine and you may have some or all of the following symptoms.
- difficulty in starting to urinate
- an interrupted, weak urinary stream
- more frequent urination, especially at night
- feeling that you need to urinate right away
- leaking or dribbling
- a feeling that you cannot empty your bladder completely
As the disease progresses, untreated BPH can lead to an increased risk of complete blockage of urine flow (acute urinary retention) and/or the need for surgery.
Prostate growth is caused by a hormone in the blood called dihydrotestosterone (DHT). The dutasteride component of DUTATAM 500/400 lowers DHT production in the body, leading to shrinkage of the enlarged prostate in most men. The tamsulosin hydrochloride component of DUTATAM 500/400 acts by relaxing the smooth muscle in your prostate gland, making it easier to pass urine.
Just as your prostate became large over a long period of time, reducing the size of your prostate and improving your symptoms may take time.
Your doctor may have prescribed DUTATAM 500/400 for another reason. Ask your doctor if you are unsure why DUTATAM 500/400 was prescribed for you.
DUTATAM 500/400 is not addictive.
2. What should I know before I use DUTATAM 500/400?
Warnings
Do not use DUTATAM 500/400 if:
- you are allergic to dutasteride, tamsulosin, or any of the ingredients listed at the end of this leaflet. Always check the ingredients to make sure you can use this medicine.
- you are allergic to any other 5 alpha reductase enzyme inhibitors
- you are a woman or child.
- you have a history of a sudden drop in blood pressure upon standing up (known as orthostatic hypotension)
- you have severe liver or kidney disease
- you are taking other medications that relax the smooth muscle of your blood vessels (e.g. Flomaxtra, Minipress)

- the packaging is torn or shows signs of tampering
Check with your doctor if you:
- have any other medical conditions
- suffer from any liver or kidney conditions
- are going to have cataract surgery
- are taking any medicines to lower your blood pressure (alpha blocker medicines that relax the smooth muscles within blood vessels)
- are taking an antifungal medicine (e.g. ketoconazole)
- you have an allergy to Sulphur
- take any medicines for any other condition
During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?
Pregnancy and breastfeeding
Check with your doctor if your partner is a pregnant or intend to become pregnant or is breast feeding.
Women who are pregnant or may be pregnant, and children, must avoid handling punctured or leaking capsules. If skin contact occurs wash the area immediately with soap and water.
If dutasteride is absorbed through the skin by a woman who is pregnant with a male baby, it may cause the male baby to be born with abnormalities of the genital organs.
Dutasteride has been found in the semen of men taking dutasteride. If your partner is or may be pregnant, you must avoid exposing her to your semen as dutasteride may affect the normal development of a male baby. You must use a barrier form of contraception.
3. What if I am taking other medicines?
Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.
Tell your doctor or pharmacist if you are allergic to any foods, dyes, preservatives or any other medicines.
Some medicines may interfere with DUTATAM 500/400 and affect how it works.
- long-term combination of dutasteride with medicines that are potent inhibitors of the enzyme CYP3A4 (e.g. ritonavir, indinavir, nefazodone, itraconazole, ketoconazole) may increase the concentration of dutasteride in the blood
- antifungal medicines such as ketoconazole can lead to an increase in the concentration of tamsulosin hydrochloride in the blood
- antidepressants known as selective serotonin reuptake inhibitors (e.g. paroxetine) can lead to an increase in the concentration of tamsulosin hydrochloride in the blood
Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect DUTATAM 500/400.
4. How do I use DUTATAM 500/400?

5. What should I know while using DUTATAM 500/400?
Things you should do
Tell your doctor if, you:
- have not taken DUTATAM 500/400 as directed.
- are having a blood test, tell your doctor you are taking DUTATAM 500/400 as this medicine decreases your prostate-specific antigen (PSA) levels.
The PSA test helps your doctor to tell if you have prostate disease, including prostate cancer. If you have a higher than normal amount of PSA in your blood it could mean that you have a higher risk of prostate cancer. Men taking DUTATAM 500/400 should have their PSA measured 6 months after starting treatment and then regularly after that. You could still be at risk for prostate cancer even though your PSA is lower. Your doctor can still use PSA to help detect prostate cancer, by comparing your test results each time you have a PSA test.
Remind any doctor, dentist or pharmacist you visit that you are taking DUTATAM 500/400.
Things to be careful of
If you are having a cataract operation and are taking or have previously taken DUTATAM 500/400, the pupil may dilate poorly and the iris (the coloured part of the eye) may become floppy during the operation (floppy iris syndrome). This can be managed if your surgeon knows that you are taking DUTATAM 500/400 before you have the operation. If you are going to have eye surgery tell your surgeon that you are taking or have taken DUTATAM 500/400.
In a clinical study of men at increased risk of developing prostate cancer, a serious form of prostate cancer was reported more often in men taking DUTATAM 500/400 than men who did not take DUTATAM 500/400. The reasons for this is currently unknown but may be due to the design of the clinical study.
Be careful if you are switching from another tamsulosin containing medicine to DUTATAM 500/400 as you may experience dizziness or light headedness when standing up.
If you feel dizzy or lightheaded at any time whilst taking DUTATAM 500/400, sit or lie down until the symptoms pass.
Things you should not do
- Do not stop using this medicine suddenly or change the dose.

Continue to take this medicine as your symptoms improve.
If you do not take your medicine as directed it may interfere with your doctor's ability to monitor your PSA levels. - Do not donate blood whilst taking DUTATAM 500/400 or for 6 months after you stop treatment.
- Do not give this medicine to anyone else even if they have similar symptoms to you.
- Do not use this medicine to treat any other complaints.

In clinical studies where patients were taking both the individual components of DUTATAM 500/400, the rate of heart failure (meaning your heart does not pump blood as well as it should) was higher than in patients taking the individual components alone. However, this was seen in less than 1% of patients.
