CARDURA XL contains the active substance doxazosin mesilate and 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.
Do not take CARDURA XL:
• If you are allergic to doxazosin, other types of quinazolines (such as prazosin or terazosin), or any of the other ingredients of this medicine (listed in section 6). This may have been itching, reddening of the skin or difficulty in breathing.
• I f you are breast-feeding
• If you have any form of obstruction of the digestive tract
• If you have an enlarged prostate gland (benign prostatic hyperplasia) and have low blood pressure
• I f 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
• I f 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.
Warnings and precautions
Talk to your doctor or pharmacist before taking CARDURA XL
as it may not be suitable for you:
• If you are pregnant or trying to become pregnant
• I f you have liver disease
• I f 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 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.
Prolonged and sometimes painful erections: this occurs very rarely. If you have an erection which lasts for more than 4 hours, you should contact a doctor immediately.
Before starting treatment with CARDURA XL your doctor may perform tests to rule out other conditions such as prostate cancer that may cause the same symptoms as benign prostatic hyperplasia.
Children and adolescents
CARDURA XL is not recommended for use in children or adolescents below 18 years as safety and efficacy have not yet been established. Benign prostate hyperplasia is not relevant in children.
Other medicines and CARDURA XL
Tell your doctor or pharmacist if you are taking, have recently taken or might take any 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.

3. How to take CARDURA XL
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure. CARDURA XL is a prolonged 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.
