Doxazosin 2 mg Tablets — Generic For Cardura — Upsher-Smith

Medication Summary

Medication Summary: This section summarizes DailyMed drug label information to make the label easier to understand. It is not a substitute for the official label, pharmacist counseling, prescriber instructions, or medical advice.

Overview

Doxazosin tablets are taken by mouth and are an alpha 1-adrenergic blocker. They are used to treat the signs and symptoms of benign prostatic hyperplasia (BPH) and to treat hypertension, which means high blood pressure. For high blood pressure, the label notes that lowering blood pressure can reduce the risk of serious cardiovascular events.

For BPH, the tablets may help improve urinary symptoms such as weak stream, hesitancy, frequency, nocturia, and incomplete emptying. The label says doxazosin may be used alone or with other antihypertensive medicines.

The first dose and each dose increase can cause a drop in blood pressure, sometimes with dizziness, fainting, or other postural symptoms. Doxazosin is also linked to dizziness, fatigue, malaise, hypotension, and other side effects, and it has important warnings related to cataract surgery, prostate cancer screening before BPH treatment, and priapism.

Key Counseling Points

• Take doxazosin exactly as prescribed and do not restart after several days off without using the initial dosing regimen.
• The first dose and each dose increase can cause low blood pressure; monitor for dizziness, lightheadedness, or fainting.
• Rise slowly from sitting or lying positions to help reduce symptoms of postural hypotension.
• Tell your clinician about all medicines you take, especially PDE-5 inhibitors and strong CYP3A inhibitors, because they may increase the risk of low blood pressure.
• For BPH, the label says prostate cancer should be ruled out before starting treatment and checked for at regular intervals afterward.
• Doxazosin may cause dizziness, fatigue, somnolence, hypotension, dry mouth, edema, or palpitations.
• Report any painful erection that lasts for hours right away, since priapism is a serious warning.
• If you are having cataract surgery, tell your surgeon you take or have taken an alpha 1-blocker.
• If treatment is stopped for several days, ask how to restart safely.
• Contact a clinician promptly if you have symptoms that suggest an allergic reaction or unusual bleeding or infection, since low white blood cell counts and other reactions have been reported.
