6. Further information
1. What Co-Diovan is and what it is used for
Co-Diovan film-coated tablets contain two active substances
called valsartan and hydrochlorothiazide. Both of these
substances help to control high blood pressure (hypertension).
• 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
• Hydrochlorothiazide belongs to a group of medicines called

thiazide diuretics (also known as “water tablets”).
Hydrochlorothiazide increases urine output, which also lowers
blood pressure.
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.
2. Before you take Co-Diovan
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 (cholestasis)
• 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

• 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 blood.
• if you have diarrhoea or severe vomiting.
• if you are taking high doses of water tablets (diuretics).
• 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
• 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 sun.
• 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 etc
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

potassium in your blood.
These include potassium supplements or salt substitutes
containing potassium, potassium-sparing medicines and
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 antipsychotics.
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 supplements.
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
medicines to increase blood pressure, such as noradrenaline or
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 (Cox2 inhibitors) and acetylsalicylic acid> 3 g.
muscle relaxing medicines, such as tubocurarine.
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
cholestyramine and colestipol (medicines used mainly to treat
high levels of lipids in the blood).
ciclosporin, a medicine used for organ transplant to avoid organ
alcohol, sleeping pills and anaesthetics (medicines with
sleeping or painkilling effect used for example during surgery).
iodine contrast media (agents used for imaging examinations).

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
• 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

Co-Diovan is not recommended for mothers who are breastfeeding, and your doctor may choose another treatment for you if
you wish to breast-feed, especially if your baby is newborn, or
was born prematurely.
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.
3. How to take Co-Diovan
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 day.
• Do not change the dose or stop taking the tablets without

consulting your doctor.
• The medicine should be taken at the same time each day,

usually in the morning.
• You can take Co-Diovan with or without food.
• Swallow the tablet with a glass of water.

If you forget to take a dose, take it as soon as you remember.
However, if it is almost time for your next dose, skip the dose you
Do not take a double dose to make up for a forgotten dose.
If you stop taking Co-Diovan
