Doxazosin is indicated for the treatment of the following conditions:
??Arterial hypertension.
??Obstruction to urine flow and symptoms associated with benign prostatic hyperplasia.
Doxazosin is a drug for the treatment of arterial hypertension (HTA) and benign prostatic hyperplasia (BPH). Doxazosin may be used in patients with BPH, whether they are hypertensive or normotensive. While changes in blood pressure in normotensive patients with BPH are clinically insignificant, patients who have both conditions, HTA and BPH, can be effectively treated

Warnings and precautions
If you are going to undergo eye surgery for cataracts, please inform your doctor before the operation if you are taking or have taken DOXAZOSINA VIR previously. This is because DOXAZOSINA VIR may cause complications during the operation, which can be taken into account and controlled by your ophthalmologist if informed beforehand
Treatment requires periodic monitoring by your doctor. If you notice symptoms such as dizziness, drowsiness, or palpitations, consult your doctor, who will consider adjusting the dose
Treatment with doxazosin may cause marked hypotension, especially postural hypotension, associated with the administration of the first or initial doses. If this event occurs, consult your doctor
Use of DOXAZOSINA VIR with other medicines
Tell your doctor or pharmacist if you are using or have recently used other medicines, including those obtained without a prescription
Known hypersensitivity to quinazolines
Doxazosin did not present interaction when administered concomitantly with: warfarin, digoxin, phenytoin, and indomethacin. No adverse effects due to interaction have been observed when doxazosin was administered with other drugs used in the treatment of hypertension (thiazide diuretics, furosemide, beta-blockers), as well as with non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics, oral antidiabetics, uricosuric agents, and anticoagulants
Some patients who are receiving an alpha-blocker for the treatment of high blood pressure or prostatic hyperplasia may experience dizziness or fainting that can be caused by a decrease in blood pressure when sitting or standing up quickly. Some patients have experienced these symptoms when taking medicines for erectile dysfunction (impotence) with alpha-blockers like DOXAZOSINA VIR. In order to decrease the likelihood of these symptoms occurring, you should be receiving your daily dose of alpha-blocker regularly before starting treatment for erectile dysfunction
However, if you are taking any of the aforementioned drugs, you should consult your doctor
Pregnancy, lactation, and fertility:
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine
