1. What is Dutrozen and what is it used for

Dutrozen is used in men with an enlarged prostate gland (benign prostatic hyperplasia) - a non-cancerous enlargement of the prostate gland caused by excessive production of a hormone called dihydrotestosterone.
Dutrozen is a combination of two different active substances, dutasteride and tamsulosin.
Dutasteride belongs to a group of medicines called 5-alpha reductase inhibitors, and tamsulosin belongs to a group of alpha-blockers.
An enlarged prostate gland can lead to problems with urination, such as difficulty urinating and frequent urination. It can also cause a decrease in urine flow and a weak urine stream. If left untreated, it can lead to complete blockage of urine flow (acute urinary retention). This situation requires immediate treatment. In some cases, surgery may be necessary to remove or reduce the size of the prostate gland.
Dutasteride reduces the production of dihydrotestosterone, which helps to reduce the size of the prostate and alleviate symptoms. It also reduces the risk of acute urinary retention and the need for surgery. Tamsulosin acts by relaxing the muscles in the prostate, making it easier to urinate and quickly alleviating symptoms.

2. Important information before taking Dutrozen

When not to take Dutrozen:

  • if you are a woman(this medicine is for men only).
  • if you are a child or adolescent under 18 years of age
  • if you are allergic to dutasteride, other 5-alpha reductase inhibitors, tamsulosin, soy, peanuts (soy lecithin), or any of the other ingredients of this medicine (listed in section 6).
  • if you have low blood pressurethat causes dizziness or fainting (orthostatic hypotension).
  • if you have severe liver disease. If any of the above applies to you, do not take this medicine until you have consulted your doctor.

Warnings and precautions

Before taking Dutrozen, discuss it with your doctor.
In some clinical studies, more patients taking dutasteride and another alpha-blocker, such as tamsulosin, experienced heart failure than patients taking only dutasteride or another alpha-blocker.
Heart failure is a condition in which the heart does not pump blood as it should.

  • Tell your doctor if you have liver disease.If you have had liver disease, you may need to have additional tests while taking Dutrozen.
  • Tell your doctor if you have severe kidney disease.
  • Cataract surgery (cloudy lens).If you are scheduled to have cataract surgery, your doctor may recommend stopping Dutrozen for a while. Before surgery, tell your eye doctor that you are taking Dutrozen or tamsulosin (or have taken them in the past). Your doctor will take appropriate precautions to prevent complications during surgery.
  • Women, children, and adolescentsshould not touch damaged Dutrozen capsules, as the active substance may be absorbed through the skin. If skin contact occurs, wash the affected area immediately with soap and water.
  • Use a condom during sexual intercourse.Dutasteride has been found in the semen of men taking Dutrozen. If your partner is pregnant or may become pregnant, avoid exposing her to contact with semen. Dutasteride may affect the development of a male fetus. It has been shown that dutasteride reduces sperm count, semen volume, and sperm motility, which may lead to reduced fertility in men.
  • Dutrozen affects the result of the prostate-specific antigen (PSA) test, which is sometimes performed to detect prostate cancer. Despite this, your doctor may still order this test to detect prostate cancer. If you are having a PSA test, tell your doctor that you are taking Dutrozen. PSA levels should be regularly checked in patients taking Dutrozen.
  • In a clinical study of patients with an increased risk of prostate cancer, patients taking dutasteride were diagnosed with high-grade prostate cancer more oftenthan patients who did not take dutasteride. The effect of dutasteride on the risk of high-grade prostate cancer is not clear.
  • Dutrozen may cause breast enlargement and tenderness.If these symptoms become troublesome or if you notice breast lumpsor discharge from the nipple, contact your doctor, as these may be signs of a serious condition, such as breast cancer. If you have any questions about taking Dutrozen, contact your doctor or pharmacist.
