Terazosin:

For what conditions or diseases is this medication prescribed?
Terazosin is used in men to treat symptoms of an enlarged prostate (benign prostatic hyperplasia or CHP), which include difficulty urinating (hesitation, dribbling, weak current and incomplete emptying of the bladder), painful urination and the need to urinate with frequency and urgency It is also used alone or in combination with other medications to treat hypertension. Terazosin belongs to a class of medications called alpha blockers. It relieves the symptoms of hyperplasia by relaxing the bladder and prostate muscles. It lowers blood pressure by relaxing blood vessels so that blood can flow more efficiently through the body.
Hypertension is a common condition and when left untreated, it can cause damage to the brain, heart, blood vessels, kidneys and other parts of the body. Damage to these organs can cause heart disease, a heart attack, heart failure, stroke, kidney failure, vision loss and other problems. In addition to taking medications, making lifestyle changes will also help you control your blood pressure. These changes include eating a diet that is low in fat and salt, maintaining a healthy weight, exercising for at least 30 minutes almost every day, not smoking, and consuming alcohol in moderation.

How should this medicine be used?
Terazosin comes as a capsule to take by mouth. It is usually taken with or without food, once a day at bedtime, or twice a day. Follow the instructions on the medication label carefully and ask your doctor or pharmacist anything you do not understand. Use the medication exactly as directed.
