Frusax™ also helps lower high blood
pressure, which doctors call hypertension.
Everyone has blood pressure. This
pressure helps circulate the blood around
your body. Your blood pressure may be
different at different times of the day,
depending on how busy or worried you
are. You have hypertension (high blood
pressure) when your blood pressure stays
higher than is needed, even when you
are calm and relaxed.
If high blood pressure
is not treated it
can lead to serious health problems
such as stroke, heart disease and
kidney failure. Frusax™ helps to lower
your blood pressure.
Frusax™ works by making your kidneys
pass more water and salt. This helps
reduce high blood pressure and some
forms of swelling.

How to take Frusax
How much to take
Take Frusax™ only when prescribed by
your doctor. Your doctor will tell you how
many tablets you need to take each day.
The number will depend on your
condition and whether you are taking
other medicines. Do not take more
tablets than your doctor has prescribed.
Your doctor will follow your progress and
adjust the dose accordingly.
If you do not understand the instructions
on the label, ask your doctor or
pharmacist for help.
How to take it
Swallow Frusax™ with a glass of water.
When to take it
Take your Frusax™ everyday at about
the same time each day, unless your
doctor tells you otherwise. Take Frusax™
on an empty stomach.
Taking your tablets at the same time each
day will have the best effect. It will also help
you to remember when to take the tablets.
If you are taking a single dose a day,
take it in the morning, for example at
If you are taking more than one dose a
day, take the last dose no later than 2 pm,
unless your doctor tells you otherwise.
Frusax™ will increase the amount
of water (urine) you pass and also the
number of times you go to the toilet. By
taking the last dose no later than 2 pm
there may be less chance of your sleep
How long to take it
If you have high blood pressure or
swelling, Frusax™ helps to control the
condition but does not cure it. Therefore,
Frusax™ must be taken every day.
Continue taking Frusax™ for as long as
your doctor prescribes.
If you forget to take it
Take it as soon as you remember, and
then go back to taking your tablets as
you would normally. However, if it is
almost time for your next dose, skip the
dose you missed and take your next dose
when you are meant to.
Do not take a double dose to make up
for the dose that you missed.
If you have trouble remembering to take
your tablets, ask your pharmacist for

If you take too many tablets, you will
probably feel light-headed or dizzy. You
may also become very thirsty, confused,
have a change in the amount of urine
passed or have a fast heart beat.
While you are using Frusax
Things you must do
Have your blood pressure checked when
your doctor says to make sure Frusax™
Tell your doctor and pharmacist that you
are taking Frusax™ if you are about to
be started on any new medicine.
You may feel light-headed or dizzy when
you begin to take Frusax™. This is
because your blood pressure is falling
suddenly. Standing up slowly, especially
when you get up from bed or chairs, will
help your body get used to the change in
position and blood pressure.
Tell your doctor if you have excessive
vomiting and/or diarrhoea while taking
Frusax™, or you have any of the
dry mouth, thirst
weakness, tiredness, drowsiness
muscle pains or cramps
fast heart beat
passing less urine than normal
You may be dehydrated because you are
losing too much water.
Tell your doctor or dentist that you are
taking Frusax™ if you plan to have
surgery (even at the dentist) that needs a
general anaesthetic. Your blood pressure
may drop suddenly.
Things you must not do
Do not stop taking Frusax™ or lower
the dose because you are feeling better,
unless advised to by your doctor.
Do not give Frusax™ to anyone else even
if their symptoms seem similar to yours.
Things to be careful of
Be careful driving or operating machinery
until you know how Frusax™ affects you.
Frusax™ may cause dizziness or light-
headedness in some people, especially after
the first few doses. Make sure you know how
you react t
o Frusax™ before you drive a
car, operate machinery, or do anything else
that could be dangerous if you are dizzy or
light-headed. If you drink alcohol, dizziness
or light-headedness may be worse.
Talk to your doctor about foods or drinks
that have high potassium content.
Long term Frusax™ therapy causes a fall
in potassium levels in your body. However,
if you eat foods or have drinks that are
high in potassium this will help maintain
normal levels of potassium in your body.
Too much potassium can, however, be
harmful, therefore, it is important to
discuss your diet with your doctor.

your blood pressure
