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

What is silodosin

Silodosin belongs to a group of medicines called alpha1A-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,
• sensation of not completely emptying the bladder,
• increased need to urinate, including during the night.

2. What you need to know before starting to take/use Silodosin Normon

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

Consult your doctor or pharmacist before starting to take this medicine:

• If you are scheduled for eye surgery due to cataracts (cataract surgery), 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 medication 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 required. Ask your doctor whether it is necessary to delay or temporarily interrupt treatment with silodosin prior to undergoing cataract surgery.

• If you have ever fainted or felt dizzy upon standing 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 medications 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 must not take silodosin, as it has not been evaluated in this condition.

• If you have kidney problems, consult your doctor.

If your kidney problems are moderate, your doctor will start treatment with silodosin cautiously and possibly at a lower dose (see section 3 “Dosage”). If your kidney problems are severe, you must not take this medicine.

• Since benign prostatic enlargement and prostate cancer can cause similar 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 reverses after discontinuation of 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

Inform 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:

• medications 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 may increase during treatment with silodosin.
• 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 in 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.

Driving and use of machines

Do not drive or operate machinery if you feel weak, dizzy, or sleepy, or if you have blurred vision.

This medicine contains less than 23 mg of sodium (1 mmol) per dose; this is essentially “sodium-free”.

3. How to take/use Silodosin Normon

Follow exactly the administration instructions for this medicine 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 medicine and the amount ingested. If you feel dizzy or weak, inform your doctor immediately.

If you forget to take silodosin

You may take the capsule later the same day if you forget 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 a forgotten capsule.

If you stop taking silodosin

If you stop treatment, 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 experiences them.

Contact your doctor immediately if you experience any of the following allergic reactions, as they could have serious consequences: 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 ejaculated during sexual intercourse. This effect disappears 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 resolve. If you experience dizziness upon standing or fainting, please inform your doctor as soon as possible.
