1. What is Tamiron and what is it used for

The active substance of Tamiron is tamsulosin hydrochloride, which belongs to the group of selective alpha-1A/1D adrenergic receptor antagonists. It reduces the tension of the smooth muscles of the prostate and urethra, making it easier for urine to flow through the urethra and facilitating urination. Additionally, it reduces the feeling of pressure on the bladder. Tamiron is used in men to treat symptoms of benign prostatic hyperplasia (enlargement of the prostate gland). These symptoms may include difficulty urinating (weak urine flow), urinating in drops, pressure on the bladder, and the need to urinate frequently at night and during the day.

2. Important information before taking Tamiron

When not to take Tamiron:

• if you are allergic to tamsulosin hydrochloride or any of the other ingredients of this medicine (listed in section 6). Hypersensitivity may manifest as sudden, localized itching of soft tissues (e.g., throat or tongue), difficulty breathing, and/or itching and rash (angioedema).
• if you experience fainting due to low blood pressure when changing position (when sitting or standing up).
• in patients with severe liver function disorders.

Warnings and precautions

Before starting to take Tamiron, discuss it with your doctor or pharmacist.

• periodic medical examinations are necessary to monitor the progression of the disease being treated.
• rarely, during tamsulosin treatment, as with other drugs in this group, fainting may occur. If you experience initial symptoms of dizziness or weakness, you should sit or lie down until these symptoms pass.
• you should inform your doctor if you have severe kidney function disorders.
• if you are being prepared for or have been scheduled for eye surgery due to cataracts or increased eye pressure (glaucoma), you should inform the ophthalmologist that you have taken Tamiron, are currently taking it, or plan to take it. The ophthalmologist may then take appropriate precautions in the form of appropriate medications and surgical techniques. You should ask your doctor about the need to postpone or temporarily stop taking the medicine during eye surgery due to cataracts or increased eye pressure (glaucoma).

The medicine should not be given to children or adolescents under 18 years of age, as it has no effect in this patient group.
