TERAZOSIN CINFA 5 mg TABLETS

2. What you need to know before taking Terazosin Cinfa

Do not take Terazosin Cinfa:

• If you are allergic to terazosin or any of the other components of this medication (listed in section 6).
• If you have a history of syncope (fainting) during urination.

Warnings and precautions

Consult your doctor or pharmacist before starting to take terazosin.

• After the first or first few doses, a significant drop in blood pressure may occur.
• Symptoms of dizziness, drowsiness, fainting, and palpitations may appear, so caution should be exercised and driving or performing hazardous tasks should be avoided.
• Syncope (fainting) may occur (in less than 1% of patients) after the initial intake of the medication, after a too rapid increase in dose, or due to the simultaneous use of another antihypertensive medication. Syncope can be controlled by limiting the initial dose to 1 mg and administering any other antihypertensive medication with caution.

• Cautious use is necessary in elderly patients due to the high incidence of orthostatic hypotension in this age group.

• If you are going to undergo cataract surgery, please inform your doctor before the operation if you are taking or have previously taken terazosin. This is because terazosin may cause complications during surgery, which can be taken into account and controlled by your ophthalmologist if informed in advance.

Children and adolescents

The safety and efficacy of terazosin in children have not been established.

Use of terazosin with other medications

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

The simultaneous administration with other antihypertensives may imply a reduction in the dose of the antihypertensive and/or an adjustment of the dose of terazosin.

Hypotension has occurred when terazosin is used with phosphodiesterase inhibitors (such as sildenafil and vardenafil).

Some patients who are receiving an alpha-blocker for the treatment of high blood pressure or prostatic hyperplasia may experience dizziness or fainting, which can be 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 terazosin. To reduce the likelihood of these symptoms, you should be receiving your daily dose of alpha-blocker regularly before starting treatment for erectile dysfunction.

You can take Terazosin Cinfa with or without food. Do not consume alcohol while taking this medication.

If treatment is interrupted for several days, therapy should be restarted according to the initial administration regimen.

Hypertension:

The initial dose for all patients is 1 mg (half a tablet of Terazosin Cinfa 2 mg) once a day, at bedtime. This initial treatment regimen should be strictly followed to avoid the possibility of acute hypotension.

The daily dose may be doubled at intervals of approximately one week to achieve the desired result.

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

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