PRESCRIBED FOR: Doxazosin is used for the treatment of hypertension (high blood pressure) and benign prostatic hyperplasia (BPH).

SIDE EFFECTS: Common reactions include:

Doxazosin causes significant reduction in blood pressure after administration of the first dose (first dose effect). This reduction in blood pressure may be associated with dizziness and fainting, especially when rising from a sitting position. To avoid this, patients should rise slowly from a sitting position, start treatment with the 1 mg dose, and then doses should be adjusted upwards slowly. Priapism (painful, prolonged penile erection) and a reduction in white blood cells have been associated with doxazosin.

Doxazosin can cause intraoperative floppy iris syndrome (IFIS) during cataract surgery. Patients should inform their eye surgeon that they are taking doxazosin.

STORAGE: Doxazosin should be stored at room temperature, 15 C - 30 C (59 F - 86 F).
