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 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.

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


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 CoDiovan in early pregnancy – see pregnancy section).
 If you have severe liver disease, destruction of the small bile ducts within
the liver (billary 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 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 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 recommended.
 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 disease).
 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 pressurelowering 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
○ “ACE inhibitors” such as enalapril, lisinopril, etc
○ Aliskiren
If any of these apply to you, talk to your doctor.

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)
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 breastfeeding
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 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, CoDiovan may occasionally cause dizziness and affect the ability to concentrate.

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.
