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

Take special care with Cardura:

The following are reasons why Cardura may not be suitable for you:

-    If you are pregnant or trying to become pregnant

-    If you have liver disease

-    If you are also taking other medicines

-    If you have heart disease

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. This is because Cardura 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.

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

When you start to take Cadura 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

-    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 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.

Taking Cardura with food and drink:

Cardura can be taken with or without food.


The safety of using Cardura 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 is suitable for you. Breast-feeding:

Do not take Cardura if you are breast-feeding.
