Drug
Doxazosin
Pronounced
"dox-AZE-oh-sin"
Uses
Doxazosin is used in men to treat the symptoms of an enlarged prostate (benign prostatic hyperplasia-BPH). It does not shrink the prostate, but it works by relaxing the muscles in the prostate and part of the bladder. This helps to relieve symptoms of BPH such as difficulty in beginning the flow of urine, weak stream, and the need to urinate often or urgently (including during the middle of the night).
Doxazosin belongs to a class of drugs known as alpha blockers.
This medication should not be used to treat high blood pressure.

How to Use This Medication
Read the Patient Information Leaflet if available from your pharmacist before you start taking doxazosin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth as directed by your doctor, usually once daily with breakfast.
Doxazosin may cause a sudden drop in your blood pressure, which could lead to dizziness or fainting, usually within a few hours after you take it. This risk is higher when you first start taking this drug, after your doctor increases your dose, or if you restart treatment after you stop taking it. During these times, avoid situations where you may be injured if you faint.
Swallow the tablets whole. Do not crush or chew the tablets. Doing so can release all of the drug at once, increasing the risk of side effects.
The dosage is based on your medical condition and response to treatment.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. If you miss taking doxazosin for a few days, you may need to restart treatment at a lower dose and gradually increase your dose again. Consult your doctor for more details.
If you are switching from another form of doxazosin to this extended-release form, be sure to follow your doctor's instructions closely.
Tell your doctor if your condition does not get better or if it gets worse.
