What CANDESARTAN RBX is used for
CANDESARTAN RBX belongs to a group of medicines known as angiotensin-II receptor antagonists.
CANDESARTAN RBX is used to treat:
- high blood pressure, also called hypertension
- heart failure, usually in combination with other medicines.
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) which means your blood pressure stays high, even when you are calm and relaxed.
Regular blood pressure checks are the only way of knowing that you have hypertension. There are no symptoms of hypertension and you may feel fine. If hypertension is not treated, serious health problems such as stroke or heart attack and heart or kidney failure may occur.
CANDESARTAN RBX lowers blood pressure by dilating (expanding) small blood vessels from the heart, letting the blood be pumped around the body more easily.
Heart failure means that the heart muscle cannot pump blood strongly enough to supply all the blood needed throughout the body. Heart failure is not the same as heart attack and does not mean that the heart stops working.
Heart failure may start off with no symptoms, but as the condition progresses, patients may feel short of breath or may get tired easily after light physical activity such as walking. Some patients may wake up short of breath at night. Fluid may collect in different parts of the body, often first noticed as swollen ankles and feet.
CANDESARTAN RBX helps to treat heart failure and may improve your symptoms.
One of the ways CANDESARTAN RBX helps heart failure is that it widens the blood vessels, so that the heart does not have to pump as hard to move the blood around the body. This also means that when you place extra demands on your heart, such as during exercise, the heart may cope better so you may not get short of breath as easily.
When used to treat heart failure, CANDESARTAN RBX is almost always used with other medicines called diuretics or fluid tablets. These medicines help the kidney get rid of excess fluid from the body.
Your doctor will have explained why you are being treated with CANDESARTAN RBX and told you what dose to take.
Your doctor may have prescribed CANDESARTAN RBX for another reason.
Ask your doctor if you have any questions about why CANDESARTAN RBX has been prescribed for you.
CANDESARTAN RBX is available only with a doctor's prescription.

How to take CANDESARTAN RBX
How much to take
The usual dose is one 8 mg tablet or one 16 mg tablet taken daily. Sometimes, this may need to be increased to 32 mg taken daily.
Take CANDESARTAN RBX once a day, at about the same time each day. Keeping a regular time for taking your medicine will help to remind you to take it.
Follow all directions given to you by your doctor and pharmacist carefully.
How to take CANDESARTAN RBX
Swallow the tablets with a glass of water. It does not matter whether you take CANDESARTAN RBX tablets before or after food.
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 the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.
Do not take a double dose to make up for the dose you missed.
If you are not sure what to do, ask your doctor or pharmacist.
How long to take it for
CANDESARTAN RBX helps control your high blood pressure but does not cure it. To properly control your condition, CANDESARTAN RBX must be taken every day.
Keep taking CANDESARTAN RBX for as long as your doctor recommends.
If you take too much (overdose)
Immediately telephone your doctor, or the Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much CANDESARTAN RBX. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
If you take too much CANDESARTAN RBX, you may get a headache and feel sick, dizzy and very tired.
While you are taking CANDESARTAN RBX
Things you must do
Before starting any new medicine, tell your doctor or pharmacist that you are taking CANDESARTAN RBX.
Tell all the doctors, dentists and pharmacists who are treating you that you are taking CANDESARTAN RBX.
Tell your doctor immediately if you become pregnant or plan to become pregnant while taking CANDESARTAN RBX. You should not use CANDESARTAN RBX if you are pregnant or thinking about becoming pregnant. Your doctor can discuss different treatment options with you.
If you plan to have surgery, including dental surgery, that needs a general anaesthetic, tell your doctor or dentist that you are taking CANDESARTAN RBX.
Be sure to keep all of your doctor's appointments so that your progress can be checked. Your doctor will check your progress and may want to take some tests (eg blood tests, blood pressure) from time to time. These tests may help to prevent side effects.
Things you must not do
Do not use CANDESARTAN RBX to treat any other conditions unless your doctor tells you to.
Do not give CANDESARTAN RBX to anyone else, even if they have the same condition as you.
Do not stop taking CANDESARTAN RBX unless you have discussed it with your doctor.
Things to be careful of
Be careful driving or operating machinery until you know how CANDESARTAN RBX affects you. CANDESARTAN RBX may cause drowsiness, dizziness or lightheadedness in some people. If any of these occur, do not drive, operate machinery or do anything else that could be dangerous.
Be careful getting up from a sitting or lying position. Dizziness, lightheadedness or fainting may occur, especially when you get up quickly. Getting up slowly may help. This problem can be more common if you are also taking a diuretic (fluid tablets). 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.
If you are taking CANDESARTAN RBX for high blood pressure, make sure you drink enough water during exercise and hot weather when you are taking CANDESARTAN RBX, especially if you sweat a lot. If you do not drink enough water while taking CANDESARTAN RBX, you may faint or feel light-headed or sick. This is because your body does not have enough fluid and your blood pressure is low. If you continue to feel unwell, tell your doctor.
If you are taking CANDESARTAN RBX for heart failure, restricted fluid intake is generally recommended. Speak with your doctor about how much water you should drink.
Please talk to your doctor or pharmacist about these possibilities if you think they may bother you.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking CANDESARTAN RBX.
