6. Further information
Co-Diovan contains 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 lowered.
• 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.
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 CoDiovan in early pregnancy - see pregnancy section).
• if you have severe liver disease.
• if you have severe kidney disease.
• if you are unable to urinate.
• if you are treated with and 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
• if you have gout.
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 diarrhoea or severe vomiting.
• if you are taking high doses of water tablets (diuretics).
• if you have severe heart disease.
• 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 recommended.

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
Co-Diovan is not recommended for mothers who are breast-feeding, and
your doctor may choose another treatment for you if you wish to breastfeed, 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 CoDiovan 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 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
• You can take Co-Diovan with or without food.
• Swallow the tablet with a glass of water.

If you take more Co-Diovan than you should
If you experience severe dizziness and/or fainting, lie down and contact
your doctor immediately.
If you have accidentally taken too many tablets, contact your doctor,
pharmacist or hospital.
If you forget to take Co-Diovan
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 missed.
Do not take a double dose to make up for a forgotten dose.
If you stop taking Co-Diovan
Stopping your treatment with Co-Diovan may cause your high blood
pressure to get worse. Do not stop taking your medicine unless your
doctor tells you to.
If you have any further questions on the use of this product, ask
