Pregnancy, breast-feeding and fertility
The safety of using CARDURA during pregnancy has not been
established. If you are pregnant or planning to have a baby, ask
your doctor or pharmacist for advice before taking this medicine.
CARDURA with food and drink
Please refer to section 3.
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.
Other medicines and CARDURA
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
– 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 high blood pressure.
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.
When you start to take CARDURA 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.
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.
Persistent painful erections may occur very rarely.
If this happens you should contact a doctor immediately.
