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

Dutasteride/tamsulosin is used in men to treat enlarged prostate (benign prostatic hyperplasia) – a non-cancerous growth of the prostate caused by overproduction of a hormone called dihydrotestosterone, in patients already controlled with dutasteride and tamsulosin administered together.

This medicine is a combination of two different medicines called dutasteride and tamsulosin. Dutasteride belongs to a group of medicines known as 5-alpha reductase enzyme inhibitors, and tamsulosin belongs to a group of medicines known as alpha-blockers.

As the prostate enlarges, it may cause urinary problems such as difficulty in urine flow 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 not treated, there is a risk that urine flow may become completely blocked (acute urinary retention). This 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 size of the prostate and relieve symptoms. This reduces the risk of acute urinary retention and the need for surgery. Tamsulosin works by relaxing the muscles of the prostate, making urination easier and rapidly improving symptoms.

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

Do not take dutasteride/tamsulosin

• if you are allergic (hypersensitive) to dutasteride, to other 5-alpha reductase enzyme inhibitors, to tamsulosin, to soy, peanuts, or to any of the other ingredients of this medicine (listed in section 6).
• if you suffer from fainting due to a drop in blood pressure when changing posture (sitting and standing) (orthostatic hypotension).
• if you have severe liver disease.
• if you are a woman, child, or adolescent.

Consult your doctor if you think you are in any of these situations.

This medicine is for men only. It must not be taken by women, children, or adolescents.

Warnings and precautions

Talk to your doctor before starting to take this medicine:

• in some clinical studies, the number of patients who experienced heart failure was higher in those taking dutasteride and another medicine called an alpha blocker, such as tamsulosin, than in patients taking only dutasteride or only an alpha blocker. Heart failure means that your heart does not pump blood as it should.

• if you have liver problems. If you have any condition affecting your liver, you may need additional monitoring during treatment with this medicine.

• if you have kidney problems.

• if you are scheduled for cataract surgery (cloudy lens), inform your ophthalmologist that you are currently taking or have previously taken this medicine. Your ophthalmologist will need to take appropriate precautions to avoid complications during surgery.

• women, children, and adolescents must 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 should be washed immediately with water and soap.

• 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, since 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.

• this medicine affects the blood PSA test (prostate-specific antigen), which is sometimes used to detect prostate cancer. Your doctor may still use this test to detect 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 this medicine. Men taking this medicine should have regular PSA monitoring.

• in a clinical study conducted in men at high risk of developing prostate cancer, men who took dutasteride more frequently developed a more severe type of prostate cancer than those who did not take dutasteride. The effect of dutasteride on this severe type of prostate cancer is not clear.

• this medicine may cause breast enlargement and 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 male breast cancer.

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 group (oral 5-alpha-reductase inhibitor). If you experience any of these symptoms, contact your doctor as soon as possible for further medical advice.

Taking dutasteride/tamsulosin with other medicines

Inform your doctor or pharmacist if you are using, have recently used, or might need to use any other medicines. This includes any medicines purchased without a prescription.

Do not take dutasteride/tamsulosin with these medicines:

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

The use of dutasteride/tamsulosin with these medicines is not recommended:

• ketoconazole (used to treat fungal infections).

Certain medicines may interact with dutasteride/tamsulosin, increasing the risk of adverse 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 HIV)
• itraconazole or ketoconazole (for fungal infections)
• nefazodone (an antidepressant)
• cimetidine (for stomach ulcers)
• warfarin (for blood clotting)
• erythromycin (an antibiotic used to treat infections) in combination with paroxetine (an antidepressant) or in combination with terbinafine (used to treat fungal infections)
• terbinafine (for fungal infections)
• diclofenac (used to treat pain and inflammation).

Inform your doctor if you are taking any of these medicines.

Taking dutasteride/tamsulosin with food and drinks

Take this medicine 30 minutes after the same meal each day.

Do not take dutasteride/tamsulosin with alcoholic beverages. Alcohol may worsen the adverse effects of this medicine.

Pregnancy, breastfeeding, and fertility

Pregnant women (or those who may be pregnant) must avoid contact with broken capsules. Dutasteride is 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.

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 male fertility.

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

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine.

Driving and using machines

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

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