1) What Cardura XL and what it is used for
Cardura XL 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 XL 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 XL is taken to treat poor
and/or frequent passing of urine. This is common in patients with an enlarged
prostate gland. Cardura XL works by relaxing muscle around the bladder exit
and prostate gland so urine is passed more easily.

2) Before you take Cardura XL
Do not take Cardura XL:
 If you have had an allergic reaction in the past to Cardura XL, 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 have any form of obstruction of the digestive tract.
 If you are under 16 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
 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.
 If you have overflow incontinence (you do not feel the urge to urinate), or
anuria (your body is not producing any urine) with or without kidney
problems.
Take special care with Cardura XL:
The following are reasons why Cardura XL may not be suitable for you:
 If you are pregnant or trying to become pregnant
 If you have liver disease
 If you have heart disease
 If you are also taking other medicines

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 XL. This is because Cardura XL 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.
When you start to take Cardura XL 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 Cardura XL
 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 XL 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 XL.
Taking Cardura XL with food and drink:
Cardura XL can be taken with or without food.
Pregnancy:
The safety of using Cardura XL 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 XL is suitable for you.
Breast-feeding:
Do not take Cardura XL 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.

3) How to take Cardura XL
Cardura XL is a modified release tablet. The medicine is contained within a
non-absorbable shell that has been specially designed to slowly release the
medicine. Once swallowed, doxazosin is slowly released into the body from
the tablet, until the tablet is empty.
Since the empty tablet is eliminated from the body in bowel movements, you
may occasionally observe in the stools, something that looks like a tablet.
This is to be expected and you should not be concerned.
How to take your medicine
 The usual dose of Cardura XL is one 4mg modified release tablet taken as
a single daily dose each day.
 Your doctor may wish to increase your dose to 8mg. This is the maximum
dose of Cardura XL.
 Swallow Cardura XL whole with water. Do not chew, divide or crush the
tablets.
 Take your tablets as your doctor told you or by following the days and
arrows on the blister foil.
 If you are still not sure, ask your doctor or pharmacist.
 It is important to keep taking your tablets. They help to control your blood
pressure.

 Don't change the dose or stop taking the tablets without first checking with
your doctor.
 Don't wait until your tablets are finished before seeing your doctor.
If you have a blister strip without a label to translate the days of the week, this
translation of the days of the week is as follows:
Lu
Ma
Mi
Ju
Vi
Sa
Do
Mon
Tue
Wed
Thurs

If you take more Cardura XL than you should:
Taking too many tablets at once may make you unwell. If several tablets are
taken it may be dangerous. Tell your doctor immediately or go to your nearest
hospital casualty department immediately.

Do not worry. If you forget to take a tablet, leave that dose out completely.
