6. Contents of the package and additional information

Zayasel contains terazosin, a substance that is a selective alpha-1 adrenergic blocker, blocking some receptors in the prostate, at the neck of the bladder and in the prostatic capsule, thereby improving symptoms of benign prostatic hyperplasia (enlargement). It also produces a decrease in blood pressure without being accompanied by an increase in heart rate secondary to it.

Zayasel is indicated for the symptomatic treatment of benign prostatic hyperplasia. It is also indicated for the treatment of essential, mild or moderate arterial hypertension.

Do not take Zayasel

• If you are allergic to terazosin or any of the other components of this medication (listed in section 6).

• If you have ever experienced syncope (loss of consciousness) during urination.

• If you have heart failure or inflammation of the heart covering.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Zayasel.

Be especially careful with Zayasel:

When taking the first two doses as it may cause a significant drop in blood pressure. Symptoms of dizziness, drowsiness, drowsiness, and palpitations may occur, so be cautious with driving and performing hazardous tasks until you have checked how this medication affects you.

• When restarting treatment after its interruption, a similar effect may occur.

• After the initial intake of the medication, following a too rapid increase in dose or simultaneous use of another antihypertensive medication (to lower blood pressure), syncope (loss of consciousness) may occur (observed in less than 1 in 100 patients). This can be prevented by limiting the initial dose of Zayasel to 1 mg and administering other blood pressure medications with caution.

• If you are undergoing eye surgery for cataracts, please inform your doctor before the operation if you are taking or have taken Zayasel previously. This is because this medication may cause complications during the operation, which must be taken into account and controlled by your ophthalmologist if you have been previously informed.

• Zayasel should be used with caution in patients with liver dysfunction.

• A decrease in hemoglobin, white blood cell, and some liver function tests may occur in some patients.

Children and adolescents

The use of Zayasel is not indicated in children, as its safety and effectiveness have not been determined in this age group, as this medication is directed at treating diseases specific to adults.

Older patients

Care should be taken when administering the first dose, when increasing the dose, or when restarting treatment after an interruption, due to the high incidence of postural hypotension (low blood pressure when standing up) in this age group.

Other medications and Zayasel

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication.

Angiotensin-converting enzyme (ACE) inhibitors and DIURÉTICOS (medications used to increase urine production).

Anti-inflammatory (AINE) medications (used to treat hay fever, inflammation, and allergies).

Theophylline (medication used to treat asthma).

Nitrates (medications used to treat chest pain and angina).

Metformin, acarbose (medications used to lower blood sugar).

Sildenafil, tadalafil, vardenafil (medications used to treat erectile dysfunction).

General anesthetics (medications used to induce anesthesia).

Warfarin (medication used to thin the blood).

Some patients taking an alpha-blocker for the treatment of high blood pressure or benign prostatic hyperplasia may experience dizziness or fainting caused by a decrease in blood pressure when sitting or standing up quickly.

Some patients have experienced these symptoms when taking medications for erectile dysfunction (impotence) with alpha-blockers like Zayasel. To reduce the likelihood of these symptoms, you should be receiving your daily dose of alpha-blocker regularly before starting treatment for erectile dysfunction.

If you are taking other antihypertensive medications (to lower high blood pressure), consult your doctor. Concomitant administration with other antihypertensive medications may involve a reduction in the antihypertensive dose and/or adjustment of the Zayasel dose.

Hypotension (low blood pressure) has been observed when terazosin has been used with medications for erectile dysfunction (phosphodiesterase inhibitors) such as sildenafil and vardenafil.

Administration of Zayasel with food, drinks, and alcohol

This medication can be taken with or without food. Do not consume alcohol while taking this medication.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or intend to become pregnant, consult your doctor or pharmacist before using this medication.

The safety of terazosin during pregnancy has not been established. Zayasel should not be used during pregnancy unless clearly necessary. Your doctor will evaluate the use of this medication if you are pregnant.

If you are breastfeeding, it is not recommended that you take Zayasel. There is no information available on whether terazosin is excreted in breast milk. Inform your doctor before breastfeeding your child if you are taking Zayasel.

Driving and operating machinery

Do not drive or operate machinery until you have checked how this medication affects you, as it may cause dizziness, especially at the beginning of treatment.

Zayasel tablets contain sodium

The recommended dose must be determined by the doctor for each patient:

Benign prostatic hyperplasia (prostate enlargement):

For all patients, the initial dose is 1 mg at bedtime. This treatment regimen must be strictly followed to avoid the possibility of acute hypotension. Zayasel 5 mg tablets are not indicated for initial treatment. For the initial dose, you must use other presentations of this medication.

After 3 or 4 days, the dose may be increased to 2 mg according to each patient's response. The dose may then be increased gradually to achieve the desired clinical response.

The recommended maintenance dose is 5 mg once a day. In cases where the clinical response justifies it, the dose may be increased up to a maximum of 10 mg per day (two Zayasel 5 mg tablets).

If treatment is interrupted for several days, it is necessary to start again according to the initial administration regimen.

Hypertension:

For all patients, the initial dose is 1 mg at bedtime. This treatment regimen must be strictly followed to avoid the possibility of acute hypotension. Zayasel 5 mg tablets are not indicated for initial treatment. For the initial dose, you must use other presentations of this medication.

The daily dose may be doubled at approximately weekly intervals to achieve the desired result.

The recommended maintenance dose is 1 to 5 mg per day. However, some patients may improve with doses as high as 20 mg per day.

If treatment is interrupted for several days, it is necessary to start again according to the initial administration regimen.

Older patients

The dose should be kept as low as possible and increased under close supervision

Liver insufficiency

The dose of patients with liver dysfunction should be adjusted carefully.

Inform your doctor if you are taking or are about to start taking other medications to treat high blood pressure, as you may need to reduce your Zayasel dose.

Use in children and adolescents

This medication should not be administered to children and adolescents as the efficacy and safety of terazosin have not been studied in this population.

If you take more Zayasel than you should

In case of overdose or accidental ingestion, consult your doctor, pharmacist, or call the Toxicological Information Service, phone 91 562 04 20, indicating the medication and the amount ingested. If you take more Zayasel than you should, you may experience acute hypotension.

If you forget to take a dose, take it as soon as you remember. Then continue using Zayasel according to your doctor's instructions.

Do not take a double dose to compensate for the missed doses.

If you interrupt treatment with Zayasel
