? 1. Wandhatwhat
it is used for
CARDURA is one of a group of medicines called alphablockers. 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.



Do not take CARDURA:
– If you have had an allergic reaction in the past to
CARDURA, the active ingredient doxazosin, other
types of quinazolines (such as prazosin or terazosin)
or any of the other ingredients listed in section 6.
This may have been itching, reddening of the skin or
difficulty in breathing.
– If you are breast-feeding
– If you are under 18 years of age
– If you have an enlarged prostate gland (benign prostatic
hyperplasia) and have low blood pressure
– If you have a history of a condition known as
‘orthostatic hypotension’ which is a form of low blood
pressure that causes you to feel dizzy or light-headed
when you stand up from sitting or lying down

Take special care with CARDURA:
The following are reasons why CARDURA may not be
suitable for you:
– If you are pregnant or trying to become pregnant
– If you have liver disease
– If you are also taking other medicines
– If you have heart disease
If you are undergoing eye surgery because of cataract
(cloudiness of the lens) please inform your eye specialist
before the operation that you are using or have previously
used CARDURA. This is because CARDURA may cause
complications during the surgery which can be managed if
your specialist is prepared in advance.
If any of these apply to you speak to your doctor before
taking this medicine.
If you have been told by your doctor that you have an
intolerance to some sugars, contact your doctor before
taking this medicine.
When you start to take CARDURA you may experience
faintness or dizziness caused by low blood pressure, when
getting up from sitting or lying down. If you feel faint or
dizzy, you should sit or lie down until you feel better and
avoid situations where you might fall or hurt yourself. Your
doctor may want to measure your blood pressure regularly
at the start of therapy to reduce the possibility of these
effects happening.
Taking other medicines:
There are some medicines that may interact with
– Some patients who take alpha-blocker therapy for
the treatment of high blood pressure or prostate
enlargement may experience dizziness or lightheadedness, which may be caused by low blood
pressure upon sitting or standing up quickly. Certain
patients have experienced these symptoms when
taking drugs for erectile dysfunction (impotence) with
alpha-blockers. In order to reduce the likelihood that
these symptoms occur, you should be on a regular daily
dose of your alpha blocker before you start drugs for
erectile dysfunction.
– Cardura may lower your blood pressure even more if
you are already taking other medicines to treat your
high blood pressure such as terazosin and prazosin.
You should always tell your doctor if you are taking or
have recently taken any other medicine, even those not
prescribed, because they might interact with CARDURA.
Taking CARDURA with food and drink:
CARDURA can be taken with or without food.
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.
Driving and using machinery:
Take care if you drive or operate machinery. Your tablets
may affect your ability to drive or operate machinery safely,
particularly when you first start to take them. They may
make you feel weak or dizzy. If affected, do not drive or
operate machinery and contact your doctor immediately.




– If you have an enlarged prostate gland with one of the
following: any kind of congestion or blockage in your
urinary tract, a longstanding infection of the urinary
tract or you have bladder stones.
