1. What Doxazosin is and what it is used for
Doxazosin is one of a group of medicine called alpha-blockers. It is used to treat high blood pressure or the symptoms caused by enlargement of the prostate gland in men.
Doxazosin is used to treat the following:
• High blood pressure (hypertension), they works by relaxing blood vessels so that blood passes through them more easily, and helps to lower blood pressure.
• Urinary outflow obstruction and symptoms associated with an enlarged prostate gland (benign prostatic hyperplacia). It works by relaxing muscle around the bladder exit and the prostate gland so urine is passed more easily.
2. What you need to know before you take Doxazosin Do not take Doxazosin if:
You are allergic (hypersensitive) to Doxazosin or any of the other ingredients of this medicine (listed in section 6).This may have been itching, reddening of skin or difficulty in breathing.
• You are breast feeding
• You have history of a condition known as “orthostatic hypotension” which is a form of low blood pressure that causes you to feel dizzy and light-headed when you stand up from sitting or lying down
• You have an enlarged prostate gland (benign prostatic hyperplasia) and have low blood pressure
• You have an enlarged prostate gland and you have any kind of congestion or blockage of the urinary tract, a long standing infection of the urinary tract or you have bladder stones
