1. What Doxazosin is and
what it is used for
Doxazosin belongs to the
group known as vasodilators.
These substances cause the
blood vessel to widen, which
reduces the blood pressure.
Doxazosin can also reduce
tension in the muscle tissues
of the prostate and the
urinary tract.
Doxazosin is used to treat:
• high blood pressure;
• symptoms of an enlarged

If you are undergoing eye

(cloudiness of the lens)

Doxazosin may cause
complications during the
surgery which can be
managed if your specialist is
prepared in advance.
Important information
about Doxazosin
The likelihood of your blood
pressure dropping too fast is
greatest at the start of
treatment or when the dosage
is increased. You may
observe this as dizziness or
more rarely fainting when
changing position. To reduce
the risk of this happening,
your doctor will check your
blood pressure thoroughly at
the start of treatment and
when the dosage is
increased. You should
therefore avoid situations at
the start of treatment in which
dizziness or faintness could
cause injury.
Doxazosin may also affect
the results of some blood and
urine tests. If you are due to
have a blood or urine test
make sure that you tell you
are taking Doxazosin.


Children and adolescents
Doxazosin is not recommended for
use in children or adolescents below
18 years as safety and efficacy have
not yet been established.’
Other medicines and Doxazosin
Tell your doctor or pharmacist if you
are taking or have recently taken or
might take any other medicines.
• 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.
• Doxazosin may lower your blood
pressure even more if you are
already taking other medicines to
treat high blood pressure such as
terazosin and prazosin;
• nitrates (medicines for heart
problems) such as nitroglycerine
and isosorbide nitrate: these can
exacerbate the hypotensive effect;
• certain painkillers for rheumatism
(known as non-steroidal
anti-inflammatory drugs) such as
naproxen, ibuprofen or any other
anti-inflamatory painkiller: these
can reduce the hypotensive effect;
• medications that could also
possibly affect the liver
metabolism, e.g. cimetidine (a
medicine for stomach problems);
Pregnancy, breast-feeding and
Ask your doctor or pharmacist for
advice before taking any medicine.
The safety of using doxazosin during
pregnancy has not been established.
If you are pregnant or think you may
be pregnant or are planning to have a
baby, ask your doctor or pharmacist
for advice before taking this
Doxazosin should only be used
during pregnancy if your doctor
decides that the benefits for the
mother outweigh the possible risk for
the foetus.
Do not breast feed while taking
Driving and using machines
Doxazosin can sometimes cause
dizziness or fainting. In such an
event, you should exercise care
during activities that require
attentiveness, such as driving,
operating machinery and working at
heights. If you are unsure whether
Doxazosin is having a negative effect
on your ability to drive, discuss this
with your doctor.
Doxazosin contains lactose. If you
have been told by your doctor that
you have an intolerance to some
sugars contact your doctor before
taking this medicinal product.
3. How to take Doxazosin
Always take this medicine exactly as
your doctor has told you. You should
check with your doctor or pharmacist
if you are not sure.
The recommended dose is:
The initial dose is 1mg daily
(= 24 hours) in a single dose. After
1 to 2 weeks, the dose is generally
increased to 2mg in a single daily
dose (= 24 hours). This dose is also
retained for 1 to 2 weeks. If
necessary, the dosage can be further
increased to 4, 8 or 16mg per day,
until the desired reduction in blood
pressure is achieved. The maximum
daily dose is 16mg.
An initial dose should preferably be
taken before going to bed; this means
that any dizziness you may
experience is less of a problem.
The initial dose is 1 mg daily
(= 24 hours) in a single dose. After
this the usual dose is 2 mg or 4 mg
daily. In some circumstances this
may be increased to a maximum of
8mg daily.
The tablets should be taken as a
single dose each day (= 24 hours).
The tablets must be taken with plenty
of water.
If you take more Doxazosin than
you should
If you have taken more than the
prescribed dose, you should consult
your doctor and/or pharmacist
immediately. If you feel extremely
dizzy or think you might faint, you
should lie down immediately with
your head down.
If you forget to take Doxazosin
If you have forgotten to take a tablet,
then skip it and take the next tablet at
the usual time. You should check with
your doctor or pharmacist if you are
unsure. Do not take a double dose to
make up for a forgotten Dose.
If you stop taking Doxazosin
If you suddenly stop taking
doxazosin, the complaints you
suffered prior to the start of treatment
may recur. It is therefore better not to
stop taking this medication suddenly.
Your doctor will decrease the dosage
gradually. You should always check
with your doctor or pharmacist if you
are unsure.
If you have any further
questions on the use of this
medicine, ask your doctor or
