6. Further information
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 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
anuria (your body is not producing any urine) with or without kidney
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 of the eye) 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
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.
Taking Cardura XL with food and drink:
Cardura XL can be taken with or without food.
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.
Do not take Cardura XL if you are breast-feeding.

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.
