1. Contents of the pack and other information

1. What Dutasteride/Tamsulosin Stadafarma is and what it is used for

Dutasteride/tamsulosin is used in men to treat an enlarged prostate (benign prostatic hyperplasia) – a non-cancerous growth of the prostate caused by overproduction of a hormone called dihydrotestosterone.

Dutasteride/Tamsulosin Stadafarma is a combination of two different medicines called dutasteride and tamsulosin.

Dutasteride belongs to a group of medicines known as 5-alpha reductase inhibitors, and tamsulosin belongs to a group of medicines known as alpha-blockers.

As the prostate enlarges, it can cause urinary problems such as difficulty in passing urine and a need to urinate more frequently. It may also cause the urine stream to become weaker and less forceful. If benign prostatic hyperplasia is left untreated, there is a risk that urine flow may become completely blocked (acute urinary retention), which requires immediate medical treatment. In some cases, surgery may be necessary to reduce the size of the prostate or to remove it.

Dutasteride reduces the production of dihydrotestosterone, helping to shrink the prostate and relieve symptoms. This reduces the risk of acute urinary retention and the need for surgery. Tamsulosin works by relaxing the muscles in the prostate, making urination easier and rapidly improving symptoms.

2. What you need to know before taking Dutasteride/Tamsulosin Stadafarma

Do not take Dutasteride/Tamsulosin Stadafarma

• if you are a woman (because this medicine is only for men).
  • if you are a child or adolescent under 18 years of age.
  • if you are allergic to dutasteride, other 5-alpha reductase enzyme inhibitors, tamsulosin, soy, peanut, or any of the other ingredients of this medicine (listed in section 6).
  • if you have low blood pressure, causing dizziness, lightheadedness, or fainting (orthostatic hypotension).
  • if you have severe liver disease.

? If you think you are in any of these situations, do not take this medicine until you have consulted your doctor.

Warnings and precautions

Talk to your doctor before starting to take Dutasteride/Tamsulosin Stadafarma:

• In some clinical studies, there was a higher number of patients taking dutasteride and another medicine called an alpha blocker, such as tamsulosin, who developed heart failure compared to patients taking only dutasteride or only an alpha blocker. Heart failure means that your heart does not pump blood as well as it should.

• Make sure your doctor knows if you have liver problems. If you have any condition affecting your liver, you may need additional monitoring during treatment with dutasteride/tamsulosin.

• Make sure your doctor knows if you have severe kidney problems.

• Cataract surgery (cloudy lens). If you are scheduled for cataract surgery, your doctor may ask you to stop taking dutasteride/tamsulosin for a period before the operation. Before surgery, inform your ophthalmologist that you are taking dutasteride/tamsulosin or tamsulosin (or have taken them previously). Your specialist will need to take appropriate precautions to avoid complications during surgery.

• Women, children, and adolescents should avoid contact with broken capsules of dutasteride/tamsulosin, as the active ingredient can be absorbed through the skin. If any contact with the skin occurs, the affected area must be washed immediately with soap and water.

• Use a condom during sexual intercourse. Dutasteride has been found in the semen of men taking dutasteride/tamsulosin. If your partner is pregnant or suspects she might be pregnant, you must avoid exposing her to your semen, as dutasteride may affect the normal development of a male fetus. Dutasteride causes a reduction in sperm count, sperm motility, and semen volume. This may reduce your fertility.

• Dutasteride/tamsulosin affects the serum PSA test (prostate-specific antigen), which is sometimes used to detect prostate cancer. Your doctor may still use this test to screen for prostate cancer, but must be aware of this effect. If you have a blood test to measure your PSA, inform your doctor that you are taking dutasteride/tamsulosin. Men being treated with dutasteride/tamsulosin should have regular PSA monitoring.

• In a clinical study in men at increased risk of prostate cancer, men taking dutasteride developed a higher frequency of a more serious type of prostate cancer than those not taking dutasteride. The effect of dutasteride on this serious type of prostate cancer is not fully understood.

• Dutasteride/tamsulosin may cause breast enlargement and breast tenderness. If this causes discomfort, or if you notice lumps in the breast or nipple discharge, consult your doctor, as these changes may be signs of a serious condition, such as breast cancer.

? Talk to your doctor or pharmacist if you have any questions about taking dutasteride/tamsulosin.

Other medicines and Dutasteride/Tamsulosin Stadafarma

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Do not take dutasteride/tamsulosin with these medicines:

• other alpha blockers (for enlarged prostate or high blood pressure)

It is not recommended to take dutasteride/tamsulosin with these medicines:

• ketoconazole (used to treat fungal infections)

Certain medicines may interact with dutasteride/tamsulosin or increase the risk of side effects. Some of these medicines are:

• PDE5 enzyme inhibitors (used to achieve or maintain an erection), such as vardenafil, sildenafil citrate, and tadalafil
• verapamil or diltiazem (for high blood pressure)
• ritonavir or indinavir (for AIDS)
• itraconazole or ketoconazole (for fungal infections)
• nefazodone (an antidepressant)
• cimetidine (for stomach ulcer)
• warfarin (for blood clotting)
• erythromycin (an antibiotic used to treat infections)
• paroxetine (an antidepressant)
• terbinafine (used to treat fungal infections)
• diclofenac (used to treat pain and inflammation)

?Tell your doctor if you are taking any of these medicines.

Taking Dutasteride/Tamsulosin Stadafarma with food and drink

You should take dutasteride/tamsulosin 30 minutes after the same meal each day.

Pregnancy, breastfeeding, and fertility

Women must not take dutasteride/tamsulosin.

Pregnant women (or women who may be pregnant) must avoid contact with broken capsules. Dutasteride can be absorbed through the skin and may affect the normal development of a male fetus. This risk is particularly important during the first 16 weeks of pregnancy.

?Consult your doctor if a pregnant woman has been exposed to dutasteride/tamsulosin.

Use a condom during sexual intercourse. Dutasteride has been found in the semen of men taking dutasteride/tamsulosin. If your partner is pregnant or suspects she might be pregnant, you must avoid exposing her to your semen.

Dutasteride/tamsulosin has been shown to reduce sperm count, sperm motility, and semen volume. This may reduce your fertility.

Driving and using machines

Some people may experience dizziness during treatment with dutasteride/tamsulosin, which could affect their ability to drive or operate machinery safely.

?Do not drive or operate machinery if you are affected in this way.

Dutasteride/Tamsulosin Stadafarma contains sunset yellow FCF (E110) and soy lecithin

This medicine may cause allergic reactions because it contains sunset yellow FCF. It may cause asthma, especially in patients allergic to acetylsalicylic acid.

This medicine contains soy lecithin. Do not use this medicine if you are allergic to peanut or soy.

This medicine contains less than 1 mmol of sodium (23 mg) per capsule; therefore, it is essentially “sodium-free”.

Mood changes and depression

Depressed mood, depression, and, less frequently, suicidal thoughts have been reported in patients treated with another medicine in the same therapeutic class (oral 5-alpha-reductase inhibitor). If you experience any of these symptoms, contact your doctor for medical advice as soon as possible.

3. How to take Dutasteride/Tamsulosin Stadafarma

Follow exactly the instructions for taking this medicine as given by your doctor or pharmacist. If you do not take dutasteride/tamsulosin regularly, your PSA levels may be affected. If in doubt, consult your doctor or pharmacist again.
