1. What Silodosin TecniGen is and what it is used for

What is silodosin

Silodosin belongs to a group of medicines called alpha-1A adrenergic receptor blockers.

Silodosin is selective for receptors located in the prostate, bladder, and urethra. By blocking these receptors, it causes relaxation of the smooth muscle of these tissues. This makes it easier for you to urinate and alleviates your symptoms.

What silodosin is used for

Silodosin is used in adult men to treat urinary symptoms associated with benign prostatic hyperplasia (BPH), such as:

• difficulty starting urination,
• feeling of not emptying the bladder completely,
• need to urinate more frequently, even at night.

2. What you need to know before you take Silodosin TecniGen

Do not take Silodosin

• if you are allergic to silodosin or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before you start taking silodosin.

• If you are going to have eye surgery for cataracts, it is essential that you inform your ophthalmologist immediately that you are using or have previously used silodosin. This is because some patients treated with this type of medicine have experienced a loss of muscle tone in the iris (the colored part of the eye) during this type of surgery. The ophthalmologist may then take appropriate precautions regarding the medical and surgical techniques to be employed. Ask your doctor if it is necessary to postpone or temporarily interrupt treatment with silodosin when you are going to undergo cataract surgery.

• If you have ever fainted or felt dizzy when standing up, inform your doctor before taking silodosin.

When taking silodosin, dizziness may occur when standing up, and occasionally, fainting, especially when starting treatment or if you are taking other medicines that lower blood pressure. If this happens, sit or lie down immediately until the symptoms disappear and inform your doctor as soon as possible (see also the section "Driving and using machines").

• If you have severe liver problems, you should not take silodosin, as it has not been evaluated in this situation.

• If you have kidney problems, ask your doctor for advice.

If your kidney problems are moderate, your doctor will start treatment with silodosin with caution and possibly with a lower dose (see section 3).

If your kidney problems are severe, you should not take silodosin.

• Since benign prostatic hyperplasia and prostate cancer can cause the same symptoms, your doctor will examine you to rule out prostate cancer before starting treatment with silodosin. Silodosin is not used to treat prostate cancer.

Children and adolescents

Do not give this medicine to children and adolescents under 18 years of age, as there are no relevant indications for this age group.

Other medicines and Silodosin TecniGen

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

Tell your doctor in particular if you are taking:

• medicines that lower blood pressure(especially alpha-1 blockers, such as prazosin or doxazosin), as there may be a potential risk that the effect of these medicines increases during the use of silodosin,
• antifungal medicines(such as ketoconazole or itraconazole), medicines used for HIV/AIDS(such as ritonavir), or medicines used after transplants to prevent organ rejection(such as cyclosporine), as these medicines may increase the blood levels of silodosin,
• medicines used to treat erection problems(such as sildenafil or tadalafil), as their concomitant use with silodosin may lead to a slight decrease in blood pressure,
• medicines for epilepsy or rifampicin(a medicine used to treat tuberculosis), as the effect of silodosin may be reduced

Treatment with silodosin may lead to abnormal ejaculation (reduced amount of semen expelled during sexual intercourse), which may temporarily affect male fertility. This effect disappears after stopping treatment with silodosin. Inform your doctor if you are planning to have children.
