1. What TERAZOSINA ZENTIVA is and what it is used for

This medicinal product contains the active substance terazosin, which belongs to a class of medicines called
alpha-adrenergic antagonists or "alpha-blockers". Terazosin works by relaxing blood vessels, thereby lowering
blood pressure, and by relaxing the bladder and muscles of the urinary system to help urine flow in patients
with prostate problems (benign prostatic hyperplasia).
TERAZOSINA ZENTIVA is indicated:

  • for the treatment of high blood pressure (mild to moderate hypertension);
  • for urinary obstruction due to enlargement of the prostate (benign prostatic hyperplasia).

2. What you need to know before taking TERAZOSINA ZENTIVA

Do not take TERAZOSINA ZENTIVA

  • if you are allergic to terazosin, to similar substances (quinazolines such as prazosin, doxazosin) or to any of the other ingredients of this medicine (listed in section 6);
  • if you have previously experienced a temporary loss of consciousness while urinating (micturition syncope).

Warnings and precautions
Talk to your doctor or pharmacist before taking TERAZOSINA ZENTIVA.
While taking this medicine, your doctor should monitor you, especially after taking the first dose or if your doctor has increased your dose, as you may experience dizziness due to a marked drop in blood pressure, particularly when standing up (orthostatic hypotension). If you experience dizziness, lightheadedness, weakness, drowsiness or temporary loss of consciousness, lie down or sit down and contact your doctor immediately.
The risk of low blood pressure is higher if:

  • you are taking medicines for erectile dysfunction (phosphodiesterase type 5 inhibitors such as sildenafil, tadalafil, vardenafil; see section “Other medicines and TERAZOSINA ZENTIVA”);
  • you have a prostate problem (benign prostatic hyperplasia);
  • you are over 65 years old;
  • you restart treatment after missing a dose of this medicine (see section “If you forget to take TERAZOSINA ZENTIVA”); in this case, be especially careful and consult your doctor.

To reduce the risk of low blood pressure, take exactly the dose prescribed by your doctor. Take the first dose of this medicine just before going to bed and avoid sudden movements, especially if you are elderly.
Take TERAZOSINA ZENTIVA with caution and consult your doctor if:

  • you have a heart condition (aortic or mitral stenosis) causing fluid accumulation in the lungs (pulmonary edema);
  • you have severe heart problems (severe heart failure);
  • you have had a heart attack (right ventricular infarction) caused by problems in the blood vessels supplying the lungs (pulmonary embolism) or by fluid accumulation in the membrane surrounding the heart (pericardial effusion);
  • you have had a heart attack in a part of the heart called the left ventricle, associated with low blood pressure;
  • you are scheduled for eye surgery (cataract surgery) and are currently taking or have previously taken tamsulosin or any other medicine belonging to the class of medicines known as alpha-adrenergic antagonists or "alpha-blockers" (alpha-1 adrenergic antagonists); in this case, inform your surgeon;
  • you are taking other medicines that may affect liver function;

3. How to take TERAZOSIN ZENTIVA

Take this medicine exactly as prescribed by your doctor or pharmacist. If you have
any doubts, consult your doctor or pharmacist.
Take the tablet by mouth with a glass of water.
The first time you take TERAZOSIN ZENTIVA or if your dose is changed by your doctor,
you must take the first tablet in the evening before going to bed. Afterwards, you may take the tablets in the morning.
The tablet can be divided into equal parts.
The dose should be adjusted according to your health condition. Therefore, your doctor will evaluate the most suitable dose for you and may adjust it, bearing in mind the following:

Recommended initial dose
The maximum initial dose is 1 mg (half a 2 mg divisible tablet), to be taken in the evening before going to bed, to avoid a sudden drop in blood pressure (see section “Warnings and precautions”).

Subsequent doses
Subsequent doses depend on the type of therapy:

Treatment of high blood pressure (mild to moderate hypertension)
Your doctor may double the dose of terazosin each week until the desired effect is achieved.
The maximum recommended maintenance dose is 20 mg per day. Do not exceed this dose.

Treatment of high blood pressure in combination with other medicines (thiazide diuretics and other antihypertensive agents)
If, during treatment with TERAZOSIN ZENTIVA, a diuretic or another medicine for high blood pressure (antihypertensive) is prescribed for you, your doctor may reduce or discontinue treatment with TERAZOSIN ZENTIVA. If treatment is restarted, it will begin again with the lowest dose, gradually increasing the dose. Your doctor will determine the appropriate dose for you to avoid sudden drops in blood pressure (see section “Other medicines and TERAZOSIN ZENTIVA”).

Treatment of benign prostatic hyperplasia
The recommended initial dose is half a 2 mg tablet per day for 7 days. Afterwards, your doctor may double the dose every week or every two weeks, depending on your health condition. The treatment follows this schedule:

  • half a 2 mg tablet per day for 7 days;
  • 2 mg tablets for 14 days;
  • 5 mg tablets for 7 days.

The usual maintenance dose ranges between 5 mg and 10 mg, taken once daily.
Your doctor should assess your response to treatment every four weeks.
At the beginning of therapy or when your doctor changes the dose, transient side effects may occur. If these effects persist, inform your doctor, who may consider reducing the dose (see section “Possible side effects”).

Use in elderly patients
If you are elderly, your doctor will carefully determine the initial dose of TERAZOSIN ZENTIVA. If treatment with this medicine is interrupted, it is recommended to restart with the initial dose.

Use in patients with liver problems (hepatic impairment)
If you have liver problems, the optimal dose should be determined with particular caution.
If you have severe liver problems (severe hepatic dysfunction), the use of TERAZOSIN ZENTIVA should be avoided (see section “Warnings and precautions”).

If you take more TERAZOSIN ZENTIVA than you should
In case of overdose, a sudden drop in blood pressure may occur. If you experience symptoms of low blood pressure, lie down and contact your doctor immediately.
If you have taken or ingested an excessive dose of this medicine, contact your doctor immediately or go to the nearest hospital.

If you forget to take TERAZOSIN ZENTIVA
Do not take a double dose to make up for the forgotten tablet.
If you forget to take the tablet for several days, inform your doctor, as it may be necessary to restart treatment with the lowest dose. In this case, take TERAZOSIN ZENTIVA with caution, as you may experience a decrease in blood pressure (see section “Warnings and precautions”).

If you stop taking TERAZOSIN ZENTIVA
If you are taking this medicine for the treatment of high blood pressure, do not stop treatment unless otherwise advised by your doctor.
If treatment with TERAZOSIN ZENTIVA needs to be interrupted, your doctor will need to re-establish the optimal dose, starting again with the recommended initial dose of 1 mg at bedtime.

If you have any doubts about how to use this medicine, consult your doctor or pharmacist.
