The name of your medicine is CO-DIOVAN
160/25mg film-coated tablets, but will be referred to
as Co-Diovan throughout this leaflet. Please note that
this leaflet also contains information about other
strengths such as Co-DIovan 80/12.5mg and
160/12.5mg tablets.
In this leaflet:

4. Possible side effects
5. How to store Co-Diovan
6. Further information

Co-Diovan film-coated tablets contain
two active substances called valsartan
and hydrochlorothiazide. Both of these
substances help to control high blood pressure
Valsartan belongs to a class of medicines
known as “angiotensin II receptor
antagonists”, which help to control high blood
pressure. Angiotensin II is a substance in
the body that causes vessels to tighten,
thus causing your blood pressure to increase.
Valsartan works by blocking the effect of
angiotensin II. As a result, blood vessels relax
and blood pressure is lowered.
Hydrochlorothiazide belongs to a group
of medicines called thiazide diuretics (also
known as “water tablets”). Hydrochlorothiazide
increases urine output, which also lowers blood
Co-Diovan is used to treat high blood pressure
which is not adequately controlled by a single
substance alone.

High blood pressure increases the workload
of the heart and arteries. If not treated, it can
damage the blood vessels of the brain, heart,
and kidneys, and may result in a stroke, heart
failure or kidney failure. High blood pressure
increases the risk of heart attacks. Lowering
your blood pressure to normal reduces the risk
of developing these disorders.

Do not take Co-Diovan:
if you are allergic (hypersensitive) to
valsartan, hydrochlorothiazide, sulphonamide
derivatives (substances chemically related
to hydrochlorothiazide) or to any of the other
ingredients of Co-Diovan.
if you are more than 3 months pregnant
(it is also better to avoid Co-Diovan in early
pregnancy - see pregnancy section).
if you have severe liver disease, destruction of the
small bile ducts within the liver (biliary cirrhosis)
leading to the build up of bile in the liver
if you have severe kidney disease.
if you are unable to produce urine (anuria).
if you are treated with an artificial kidney.
if the level of potassium or sodium in your
blood is lower than normal, or if the level of
calcium in your blood is higher than normal
despite treatment.
if you have gout.
if you have diabetes or impaired kidney function
and you are treated with a blood pressure lowering
medicine called aliskiren.
If any of the above apply to you, do not take
this medicine and speak to your doctor.
Take special care with Co-Diovan
if you are taking potassium-sparing
medicines, potassium supplements, salt
substitutes containing potassium or other
medicines that increase the amount of
potassium in your blood such as heparin.
Your doctor may need to check the amount of
potassium in your blood regularly.
if you have low levels of potassium in your
if you have diarrhoea or severe vomiting.
if you are taking high doses of water tablets
if you have severe heart disease.
if you are suffering from heart failure or have
experienced a heart attack. Follow your doctor‟s
instruction for the starting dose carefully. Your
doctor may also check your kidney function.
if you suffer from a narrowing of the kidney artery.
if you have recently received a new kidney.

if you suffer from hyperaldosteronism. This is
a disease in which your adrenal glands make
too much of the hormone aldosterone. If this
applies to you, the use of Co-Diovan is not
if you have liver or kidney disease.
if you have ever experienced swelling of the
tongue and face caused by an allergic reaction
called angioedema when taking another drug
(including ACE inhibitors), tell your doctor. If these
symptoms occur when you are taking Co-Diovan,
stop taking Co-Diovan immediately and never take
it again. See also section 4, “Possible side effects”.
if you have fever, rash and joint pain,
which may be signs of systemic lupus
erythematosus (SLE, a so-called autoimmune
if you have diabetes, gout, high levels of
cholesterol or triglycerides in your blood.
if you have had allergic reactions with the use
of other blood pressure-lowering agents of this
class (angiotensin II receptor antagonists) or if
you have allergy or asthma.
if you experience a decrease in vision or eye pain.
These could be symptoms of an increase of
pressure in your eye and can happen within hours
to a week of taking Co-Diovan. This can lead to
permanent vision loss, if not treated. If you earlier
have had a penicillin or sulphonamide allergy you
can be at higher risk of developing this.
it may cause increased sensitivity of the skin to
the use of Co-Diovan in children and adolescents
below the age of 18 years is not recommended.
you must tell your doctor if you think you are (or
might become) pregnant. Co-Diovan is not
recommended in early pregnancy, and must not be
taken if you are more than 3 months pregnant, as it
may cause serious harm to your baby if used at
that stage (see pregnancy section).
if you are taking any of the following medicines
used to treat high blood pressure:
o “ACE inhibitors” such as enalapril, lisinopril,
o Aliskiren
If any of these apply to you, talk to your doctor.
Taking other medicines
Please tell your doctor or pharmacist if you
are taking or have recently taken any other
medicines, including medicines obtained without
a prescription.
The effect of the treatment can be influenced if
Co-Diovan is taken together with certain other
medicines. It may be necessary to change the
dose, to take other precautions, or in some cases
to stop taking one of the medicines.

This especially applies to the following medicines:
lithium, a medicine used to treat some types
of psychiatric diseases.
medicines or substances that may increase the
amount of potassium in your blood. These include
potassium supplements or salt
substitutes containing potassium, potassium
sparing medicines and heparin.
medicines that may reduce the amount
of potassium in your blood, such as
diuretics (water tablets), corticosteroids, laxatives,
carbenoxolone, amphotericin or penicillin G.
some antibiotics (rifamycin group), a drug used to
protect against transplant rejection (ciclosporin) or
an antiretroviral drug used to treat HIV/AIDS
infection (ritonavir). These drugs may increase the
effect of Co-Diovan.
medicines that may induce “torsades de pointes”
(irregular heart beat), such as antiarrhythmics
(medicines used to treat heart problems) and some
medicines that may reduce the amount of sodium
in your blood, such as antidepressants,
antipsychotics, antiepileptics.
medicines for the treatment of gout, such as
allopurinol, probenecid, sulfinpyrazone.
therapeutic vitamin D and calcium
medicines for the treatment of diabetes (oral
agents such as metformin or insulins).
other medicines to lower your blood pressure
including methyldopa, ACE inhibitors (such as
enalapril, lisinopril, etc.) or aliskiren.
medicines to increase blood pressure, such as
noradrenaline or adrenaline.
digoxin or other digitalis glycosides (medicines
used to treat heart problems).
medicines that may increase blood sugar levels,
such as diazoxide or beta blockers.
cytotoxic medicines (used to treat cancer), such as
methotrexate or cyclophosphamide.
pain killers such as non-steroidal anti-inflammatory
agents (NSAIDs), including selective
cyclooxygenase-2 inhibitors (Cox-2 inhibitors) and
acetylsalicylic acid > 3g.
muscle relaxing medicines, such as
anti-cholinergic medicines, (medicines used to
treat a variety of disorders such as gastrointestinal
cramps, urinary bladder spasm, asthma, motion
sickness, muscular spasms, Parkinson‟s disease
and as an aid to anaesthesia).
amantadine (medicine used to treat Parkinson‟s
disease and also used to treat or prevent certain
illnesses caused by viruses).

cholestyramine and colestipol (medicines
used mainly to treat high levels of lipids in the
ciclosporin, a medicine used for organ
transplant to avoid organ rejection.
alcohol, sleeping pills and anaesthetics (medicines
with sleeping or painkilling effect used for example
during surgery).
iodine contrast media (agents used for imaging
Taking Co-Diovan with food and drink
You can take Co-Diovan with or without food.
Avoid taking alcohol until you have talked to
your doctor. Alcohol may make your blood
pressure fall more and/or increase the risk of you
becoming dizzy or feeling faint.
Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before
taking any medicine.
You must tell your doctor if you think that
you are (or might become) pregnant
Your doctor will normally advise you to stop
taking Co-Diovan before you become pregnant
or as soon as you know you are pregnant, and
will advise you to take another medicine instead
of Co-Diovan. Co-Diovan is not recommended
in early pregnancy, and must not be taken when
more than 3 months pregnant, as it may cause
serious harm to your baby if it is used after the
third month of pregnancy.
Tell your doctor if you are breast-feeding or
about to start breast-feeding
Co-Diovan is not recommended for mothers who
are breast-feeding, and your doctor may choose
another treatment for you if you wish to breast-feed,
especially if your baby is newborn, or was born
Driving and using machines
Before you drive a vehicle, use tools or operate
machines or carry out other activities that
require concentration, make sure you know
how Co-Diovan affects you. Like many other
medicines used to treat high blood pressure,
Co-Diovan may occasionally cause dizziness and
affect the ability to concentrate.

Always take Co-Diovan exactly as your doctor
has told you. This will help you to get the best
results and lower the risk of side effects.
You should check with your doctor or pharmacist
if you are not sure.

People with high blood pressure often do not
notice any signs of this problem. Many may
feel quite normal. This makes it all the more
important for you to keep your appointments with
your doctor even if you are feeling well.
Your doctor will tell you exactly how many
tablets of Co-Diovan to take. Depending on how
you respond to the treatment, your doctor may
suggest a higher or lower dose.
The usual dose of Co-Diovan is one tablet per
