3. How to take Cardura

Cardura is one of a group of medicines called alpha-blockers. It is
used to treat high blood pressure, or the symptoms caused by
enlargement of the prostate gland in men.
Cardura can be used to treat high blood pressure (hypertension), by
relaxing blood vessels so that blood passes through them more
easily. This helps to lower blood pressure.
In patients with an enlarged prostate gland, Cardura is taken to
treat poor and/or frequent passing of urine. This is common in
patients with an enlarged prostate gland. Cardura works by relaxing
muscle around the bladder exit and prostate gland so urine is
passed more easily.

The safety of using Cardura during pregnancy has not been
established. If you are pregnant or trying to become pregnant speak
to your doctor and he/she will decide if Cardura is suitable for you.
Do not take Cardura if you are breast-feeding.

your ability to drive or operate machinery safely, particularly when
you first start to take them. They may make you feel weak or dizzy.

doctor immediately.
