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

What silodosin is

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 in these tissues. This makes it easier for you to urinate and relieves your symptoms.

What silodosin is used for

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

• difficulty starting urination,
• feeling of incomplete bladder emptying,
• increased need to urinate, including during the night.

2. What you need to know before taking Silodosin Stada

Do not take silodosin

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

Warnings and precautions

Talk to your doctor or pharmacist before taking this medicine:

• If you are scheduled for eye surgery due to cataracts (clouding of the lens), it is important that you immediately inform your ophthalmologist that you are currently taking or have previously taken silodosin. This is because some patients treated with this type of medicine have experienced loss of iris muscle tone (the colored circular part of the eye) during this type of surgery. The ophthalmologist can then take appropriate precautions regarding the medical and surgical techniques to be used. Ask your doctor whether you need to delay or temporarily interrupt treatment with silodosin prior to cataract surgery.

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

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

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

• If you have kidney problems, consult your doctor.

If you have moderate kidney problems, your doctor will start treatment with silodosin cautiously and possibly at a lower dose (see section 3 “How to take Silodosin Stada”). If you have severe kidney problems, you should not take this medicine.

• Since benign prostatic enlargement and prostate cancer may cause the same symptoms, your doctor will examine you to rule out prostate cancer before starting treatment with silodosin. Silodosin is not effective for treating prostate cancer.

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

Children and adolescents

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

Taking silodosin with other medicines

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

In particular, inform your doctor if you are taking:

• medicines that lower blood pressure (especially alpha1-blockers such as prazosin or doxazosin), as there may be a potential risk that the effect of these medicines is increased when used together with this medicine.

• antifungal medicines (such as ketoconazole or itraconazole), medicines used for HIV/AIDS infection (such as ritonavir), or medicines used after organ transplantation to prevent organ rejection (such as cyclosporine), as these medicines may increase blood levels of silodosin.

• medicines used to treat difficulty achieving or maintaining an erection (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.

Pregnancy and fertility

Pregnancy

This medicine is not used in women, as silodosin is used for the treatment of men with benign prostatic enlargement.

Fertility

Silodosin may reduce the amount of semen, and therefore may temporarily affect the ability to father a child.

Driving and use of machines

Do not drive or operate machinery if you experience weakness, dizziness, drowsiness, or blurred vision.

This medicine contains sodium

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

3. How to take Silodosin Stada

Follow exactly the instructions for use of this medicine as given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

The recommended dose is one 8 mg silodosin capsule per day taken orally.

Take the capsule always with food, preferably at the same time each day. Do not break or chew the capsule; swallow it whole, preferably with a glass of water.

Patients with kidney problems

If you have moderate kidney problems, your doctor may prescribe a different dose. For this purpose, the 4 mg silodosin hard capsule formulation is available.

If you take more silodosin than you should

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately or call the Toxicology Information Service at telephone number: 91 562 04 20, indicating the medication and the amount ingested. If you experience dizziness or feel weak, inform your doctor immediately.

If you forget to take silodosin

You may take the capsule later on the same day if you forgot to take it earlier. If it is almost time for the next dose, do not take the missed dose. Do not take a double dose to make up for the forgotten capsule.

If you stop taking silodosin

If you stop treatment, your symptoms may return.

If you have any further questions about the use of this medicine, ask your doctor or pharmacist.

4. Possible adverse effects

Like all medicines, this medicine can cause adverse effects, although not everyone will experience them.

Contact your doctor immediately if you experience any of the following allergic reactions, as they could be serious: swelling of the face or throat, difficulty breathing, feeling faint, skin itching, or hives.

The most common adverse effect is a reduction in the amount of semen released during sexual intercourse. This effect resolves after stopping treatment with silodosin. Inform your doctor if you are planning to have children.

Dizziness, including dizziness upon standing, and occasionally fainting, may occur.

If you feel weak or dizzy, sit or lie down immediately until symptoms subside. If you experience dizziness upon standing or fainting, inform your doctor as soon as possible.

Silodosin may cause complications during cataract surgery (eye surgery due to lens clouding; see section “Warnings and precautions”).
