1 What Cardura XL is and what it is used for
2 Before you take 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
light-headedness, 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.

What Cardura XL is 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.

have been itching, reddening of the skin or difficulty in breathing.

* If you have any form of obstruction of the digestive tract
* 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
* 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

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 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.
If you forget to take Cardura XL:
Do not worry. If you forget to take a tablet, leave that dose out completely.
Then go on as before.
