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

Do not take Silodosin Viatris

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

Warnings and precautions

Tell your doctor or pharmacist before you start taking Silodosin Viatris

• 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 used Silodosin Viatris. This is because some patients treated with this type of medicine have suffered a loss of muscle tone in the iris (the colored 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 if it is necessary or not to postpone or temporarily interrupt treatment with Silodosin Viatris 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 Viatris.

When taking Silodosin Viatris, dizziness and, occasionally, fainting may occur when standing up, 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 Viatris, 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 Viatris with caution and possibly with a lower dose (see section 3 "Dosage").

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

• 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 Viatris. Silodosin Viatris is not used to treat prostate cancer.

• Treatment with Silodosin Viatris 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 Viatris. Inform your doctor if you are planning to have children.

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 Viatris

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 possible risk of increased effect of these medicines during the use of Silodosin Viatris.
• Antifungal medicines(such as ketoconazole or itraconazole), medicines used for HIV/AIDS infection(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 Viatris.
• Medicines used to treat erection problems(such as sildenafil or tadalafil), as their concomitant use with Silodosin Viatris may lead to a slight decrease in blood pressure.
• Medicines for epilepsy or rifampicin(a medicine used to treat tuberculosis), as they may reduce the effect of Silodosin Viatris.

Pregnancy and fertility

Pregnancy

This is not applicable, as Silodosin Viatris is used to treat men with benign prostatic hyperplasia. Its use is not indicated in women.

Fertility

Silodosin Viatris may reduce the amount of semen, which may temporarily affect the ability to conceive a child.

Driving and using machines

Do not drive or operate machines if you feel faint, dizzy, or sleepy or have blurred vision.

Silodosin Viatris contains sodium.

This medicine contains less than 1 mmol of sodium (23 mg) per capsule: it is essentially "sodium-free".

3. How to take Silodosin Viatris

Follow exactly the instructions of your doctor or pharmacist. If you are unsure, ask 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.

Patient with kidney problems

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

If you take more silodosin than you should

In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone: 91 562 04 20, indicating the medicine and the amount taken. If you feel dizzy or weak, inform your doctor immediately.

If you forget to take silodosin

You can take the capsule later the same day if you forget to take it before. 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 missed capsule.

If you stop taking silodosin

If you stop treatment, it is possible that your symptoms may return.

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