Dutasteride/Tamsulosin hydrochloride is used to treat men with an enlarged prostate (benign prostatic hyperplasia) - a non-cancerous growth of the prostate gland, caused by producing too much of a hormone called dihydrotestosterone.
Dutasteride/Tamsulosin hydrochloride is a combination of two different medicines called dutasteride and tamsulosin. Dutasteride belongs to a group of medicines called 5-alpha reductase inhibitors and tamsulosin belongs to a group of medicines called alpha-blockers.
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. Sometimes surgery is necessary to remove or reduce the size of the prostate gland.
Dutasteride lowers the production of a hormone called 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. Tamsulosin acts by relaxing the muscles in your prostate gland, making it easier to pass urine and rapidly improving your symptoms.
- if you’re a woman (because this medicine is for men only).
- if you’re a child or adolescent less than 18 years old.
- if you’re allergic to dutasteride, other 5-alpha reductase inhibitors, tamsulosin or to any of the other ingredients of this medicine (listed in section 6).
- if you have low blood pressure which makes you feel dizzy, lightheaded or faint (orthostatic hypotension).
- if you have a severe liver disease.
- If you think any of these apply to you, don’t take this medicine until you have checked with your doctor.
Talk to your doctor, pharmacist or nurse before taking Dutasteride/Tamsulosin hydrochloride.
- In some clinical studies, more patients taking dutasteride and another medicine called an alpha blocker, like tamsulosin, experienced heart failure than patients taking only dustasteride or only an alpha blocker. Heart failure means your heart does not pump blood as well as it should.
- Make sure your doctor knows about liver problems. If you have had any illness affecting your liver, you may need some additional check-ups while you are taking Dutasteride/Tamsulosin hydrochloride.
- Make sure your doctor knows if you have severe problems with your kidney.
- Cataract (cloudy lens) surgery. If you are going to have surgery to remove a cataract, your doctor may ask you to stop taking Dutasteride/Tamsulosin hydrochloride for a while before your operation. Tell your eye specialist before your operation that you are taking Dutasteride/Tamsulosin hydrochloride or tamsulosin (or have previously taken it). Your specialist will need to take appropriate precautions to help prevent complications during your operation.
- Women, children and adolescents must not handle leaking Dutasteride/Tamsulosin hydrochloride capsules, because the active ingredient can be absorbed through the skin. Wash the affected area immediately with soap and water if there is any contact with the skin.
- Use a condom during sexual intercourse. Dutasteride has been found in the semen of men taking Dutasteride/Tamsulosin hydrochloride. 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. Dutasteride has been shown to decrease sperm count, semen volume and sperm motility. This could reduce your fertility.
- Dutasteride/Tamsulosin hydrochloride 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/Tamsulosin hydrochloride. Men taking Dutasteride/Tamsulosin hydrochloride 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.
- Dutasteride/Tamsulosin hydrochloride may cause breast enlargement and tenderness. If this becomes troublesome, or if you notice breast lumps or nipple discharge you should talk to your doctor about these changes as these may be signs of a serious condition, such as breast cancer.
- Mood changes and depression
Depressed mood, depression and, less frequently, suicidal thoughts have been reported in patients taking another medicine from the same therapeutic class (5-alpha reductase inhibitor) by mouth. If any of these symptoms occur, contact your doctor for further medical advice as soon as possible.
- Contact your doctor or pharmacist if you have any questions about taking Dutasteride/Tamsulosin hydrochloride.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
