1. 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 XL is taken to treat 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

•    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 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

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.

. 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 4mg. 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.
