1 What Cardura XL is and what it is used for
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.
Persistent painful erections may occur very rarely. If this happens 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

take any other medicines. There are some medicines that may interact with
* 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.

taking other medicines to treat your high blood pressure such as terazosin

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
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.
