What COZAAR is used forCOZAAR lowers high blood pressure, which doctors call hypertension.COZAAR is also used to slow the progression of kidney disease in people who have type 2 diabetes mellitus (also known as non-insulin dependent diabetes) with protein in their urine (which doctors call proteinuria).Hypertension:
Everyone has blood pressure. This pressure helps get your blood all around your body. Your blood pressure may be different at different times of the day, depending on how busy or worried you are. You have hypertension (high blood pressure) when your blood pressure stays high, even when you are calm and relaxed.There are usually no symptoms of hypertension. The only way of knowing that you have hypertension is to have your blood pressure checked on a regular basis. If high blood pressure is not treated it can lead to serious health problems. You may feel fine and have no symptoms, but eventually hypertension can cause stroke, heart disease or kidney failure. COZAAR helps to lower your blood pressure.Type 2 Diabetes Mellitus:
Type 2 diabetes mellitus is a condition in which the body's cells do not respond to the effects of insulin or too little insulin is produced, resulting in an elevated blood (sugar) level, known as hyperglycaemia.Insulin maintains the appropriate level of glucose in the blood by transporting it into the body's cells so that they can produce energy or store glucose until it's needed.Hyperglycaemia can lead to serious problems with your heart, eyes, circulation or kidneys. When kidney damage occurs, its ability to filter blood is reduced, and proteins in the blood are lost in the urine. This may eventually lead to kidney failure. In people who have type 2 diabetes mellitus with protein in their urine, COZAAR helps to slow the worsening of kidney disease and reduce the need for dialysis or kidney transplantation.How it works
COZAAR belongs to a group of medicines, called angiotensin II receptor antagonists. It works to lower your blood pressure by relaxing your blood vessels. In addition, COZAAR slows the progression of kidney disease in people who have type 2 diabetes mellitus with protein in the urine.COZAAR is not addictive.Before you take COZAARWhen you must not take it

Taking other medicines
Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines and COZAAR may interfere with each other. These include:
diuretic tablets, also called fluid or water tablets, including potassium-sparing diuretics
potassium-containing salt substitutes
medicines used to relieve pain, swelling, and other symptoms of inflammation, for example, indomethacin.
lithium (a medicine used to treat mood swings and some types of depressions)
These medicines may have an additive effect with COZAAR in lowering your blood pressure, or may affect how well it works, or may lead to increases in potassium in your blood. You may need to take different amounts of your medicine, or you may need to take different medicines.Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking COZAAR.How to take COZAARHow much to take
Your doctor will tell you how many tablets you need to take each day. This depends on your condition and whether you are taking other medicines. Take COZAAR only when prescribed by your doctor.
For high blood pressure:
For most patients, the usual starting dose is one 50 mg tablet taken once a day. Some patients may need a lower starting dose. The dose may need to be increased depending on your blood pressure. Most patients take between 25 to 100 mg each day, taken as a single dose or in divided doses.For type 2 diabetes mellitus with protein in the urine:
The usual starting dose is one 50 mg tablet taken once a day. The dose may be increased to 100 mg once a day depending on your blood pressure.Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.When to take it
Take your COZAAR at about the same time each day.
Taking your tablet(s) at the same time each day will have the best effect. It will also help you remember when to take the tablets.Swallow COZAAR with a glass of water.
It does not matter whether you take COZAAR before or after food.How long to take it
COZAAR helps control your high blood pressure, but does not cure it. Therefore COZAAR must be taken every day. Continue taking COZAAR for as long as your doctor prescribes.If you forget to take it
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking your tablet(s) as you would normally.
If you are not sure whether to skip the dose, talk to your doctor or pharmacist.Do not take a double dose to make up for the dose that you missed.
If you have trouble remembering to take your tablets, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have taken too much COZAAR. Do this even if there are no signs of discomfort or poisoning.
If you take too many tablets, you will probably feel light-headed or dizzy.While you are using COZAARThings you must do
If you become pregnant while taking COZAAR, tell your doctor immediately. Your doctor needs to know immediately so that COZAAR can be replaced by another medicine.
Have your blood pressure checked when your doctor says, to make sure COZAAR is working.
If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking COZAAR.
If you feel light-headed, dizzy or faint, get up slowly when getting out of bed or standing up. You may feel light-headed or dizzy while taking COZAAR, especially if you are also taking a diuretic (fluid tablet). This may become worse if you stand up quickly as your blood pressure may fall. Standing up slowly, especially when you get up from bed or chairs, will help your body get used to the change in position and blood pressure. This problem is not common. If it occurs and gets worse or continues, talk to your doctor.
If you plan to have surgery (even at the dentist) that needs a general anaesthetic, tell your doctor or dentist that you are taking COZAAR.
Make sure you drink enough water during exercise and hot weather when you are taking COZAAR, especially if you sweat a lot. If you do not drink enough water while taking COZAAR, you may faint or feel light-headed or sick. This is because your body doesn't have enough fluid and your blood pressure is low. If you continue to feel unwell, tell your doctor.
If you have excessive vomiting and/or diarrhoea while taking COZAAR, tell your doctor. This can also mean that you are losing too much water and your blood pressure may become too low.
If your doctor has prescribed potassium tablets for you, continue taking them. COZAAR contains a very small amount of potassium, but this does not replace any potassium tablets that you may be taking.
Go to your doctor regularly for a check-up. Your doctor may occasionally do a blood test to check your potassium level in the blood and to see how your kidneys are working.
Things you must not do
Do not give COZAAR to anyone else, even if they have the same condition as you.
Things to be careful of
Be careful driving or operating machinery until you know how COZAAR affects you. As with many other medicines used to treat high blood pressure, COZAAR may cause dizziness or light-headedness in some people. Make sure you know how you react to COZAAR before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed. If you drink alcohol, dizziness orlight-headedness may be worse.
Things that would be helpful for your blood pressure
Some self help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and for more information.
your doctor may advise you to limit your alcohol intake.
eat a healthy diet which includes plenty of fresh vegetables, fruit, bread, cereals and fish. Also eat less fat and sugar.
regular exercise helps to reduce blood pressure and helps the heart get fitter, but it is important not to overdo it. Walking is good exercise, but try to find a route that is fairly flat. Before starting any exercise, ask your doctor about the best kind of programme for you.
your doctor may advise you to watch the amount of salt in your diet. To reduce your salt intake you should avoid using salt in cooking or at the table.
your doctor may advise you to stop smoking or at least cut down.
your doctor may suggest losing some weight to help lower your blood pressure and help lessenthe amount of work your heart has to do. Some people may need a dietician's help to lose weight.Side EffectsTell your doctor or pharmacist as soon as possible if you do not feel well while you are taking COZAAR.
