Read all of this leaflet carefully before you start taking this medicine
because it contains important information for you.
- Keep this leaflet. You may need to read it again.
- If you have any further questions, ask your doctor or pharmacist.
- This medicine has been prescribed for you only. Do not pass it on to
others. It may harm them, even if their signs of illness are the same as
- If you get any side effects, talk to your doctor or pharmacist. This includes
any possible side effects not listed in this leaflet. See section 4.
The name of your medicine is Co-Diovan 80/12.5mg Tablets but will be
referred to as Co-Diovan throughout this leaflet.
What is in this leaflet:
1. What Co-Diovan is and what it is used for
2. What you need to know before you take Co-Diovan
3. How to take Co-Diovan
4. Possible side effects
5. How to store Co-Diovan
6. Contents of the pack and other information
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.
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 this medicine
(listed in section 6).
- 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 (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, tell your doctor and do not take CoDiovan.
Warnings and precautions
Talk to your doctor
- 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.
- if you are taking any of the following medicines used to treat high blood
- an ACE inhibitors (for example enalapril, lisinopril, Ramipril), in
particular if you have diabetes-related kidney problems.
- aliskiren
Your doctor may check your kidney function, blood pressure, and the
amount of electrolytes (e.g. potassium) in your blood at regular intervals.
See also information under the heading “Do not take Co‑Diovan”
Co‑Diovan 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).
Other medicines and Co-Diovan
Tell your doctor or pharmacist if you are taking, have recently taken any
other medicines, or might take any other medicines.
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 CoDiovan.
- 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,
- therapeutic vitamin D and calcium supplements.
- medicines for the treatment of diabetes (oral agents such as metformin or
- other medicines to lower your blood pressure including methyldopa, ACE
inhibitors (such as enalapril, lisinopril, etc.) or aliskiren (see also
information under the headings “Do not take Co-Diovan” and “Warnings
and precautions”).
- medicines to increase blood pressure, such as noradrenaline or
- digoxin or other digitalis glycosides (medicines used to treat heart
- medicines that may increase blood sugar levels, such as diazoxide or beta
- cytotoxic medicines (used to treat cancer), such as methotrexate or
- pain killers such as non-steroidal anti-inflammatory agents (NSAIDs),
including selective cyclooxygenase-2 inhibitors (Cox-2 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
- 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 blood).
- 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 examinations).
Taking Co-Diovan with food, drink and alcohol
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
- 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 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 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
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. 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 recommended dose of Co-Diovan is one tablet per day.
- Do not change the dose or stop taking the tablets without consulting your

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 medicine, ask your
doctor or pharmacist.
