It does not contain all the information that is known about Natrilix. It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits.

What Natrilix is

The name of your medicine is Natrilix. Natrilix contains the active ingredient indapamide which belongs to a group of medicines called chlorosulphamoyl diuretics (a type of "fluid" or "water" tablet).

What Natrilix is used for

You have been prescribed Natrilix SR for high blood pressure.
Natrilix is available only with a doctor's prescription.
There is no evidence that Natrilix is addictive.

Why Natrilix is used for high blood pressure

Everyone has blood pressure. This pressure helps to circulate blood all around the body. Your blood pressure may be different at different times of the day, depending on how busy or stressed you are.
You have high blood pressure (also known as hypertension) which is when your blood pressure stays higher than is needed, even when you are calm and relaxed.
If high blood pressure is not treated it can lead to serious health problems. You may feel fine and have no symptoms, but eventually it can cause stroke, heart disease and kidney failure.
Natrilix helps to lower your blood pressure.
Ask your doctor if you have any questions about why Natrilix has been prescribed for you.

For older people or children

Elderly people can generally use Natrilix safely. However, some older people have reduced kidney function - in which case additional care may be required.
Natrilix is not recommended for use in children.

How to take Natrilix

Follow all directions given to you by your doctor and pharmacist carefully. If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
Your doctor will select a dose when they prescribe Natrilix for you. The usual dose is one tablet once daily.
Swallow your tablet with water, preferably in the morning. Do not crush or break them.

How long to take Natrilix for

Natrilix can help to control your blood pressure, but cannot cure it. Natrilix treatment is usually for life - so you should keep taking the tablets regularly unless advised otherwise by your doctor.

If you forget to take Natrilix

If your next usual dose is less than 6 hours away, just leave out the dose that you missed. Take the next dose at the usual time and continue as normal.
If your next dose is more than 6 hours away, take the dose you have missed as soon as you realise. Then take the next dose at the usual time and continue as normal.
Do not try to make up for missed doses by taking more than one dose at a time.

If you take too much Natrilix

Taking too much Natrilix (an overdose) may cause low blood pressure (also known as hypotension). Other effects like sickness, cramps, sleepiness, confusion, kidney problems, salt and water disturbances are possible. You may require urgent medical attention.

If you think that you or anyone else may have taken too much Natrilix then act immediately

Telephone your doctor or the Poisons Information Centre (13 11 26 in Australia), or go to the Accident and Emergency department at your nearest hospital. Do this even if there are no signs of discomfort or poisoning.

While you are taking Natrilix

Things you must do

Take Natrilix exactly as your doctor has prescribed. Otherwise you may not get the benefits from treatment.
Tell all doctors, dentists and pharmacists who are involved with your treatment that you are taking Natrilix.
Make sure you drink enough water during exercise and hot weather especially if you sweat a lot. This will help you avoid any dizziness or light-headedness caused by a sudden drop in blood pressure.
Tell your doctor straight away if you have excessive vomiting or diarrhoea while taking Natrilix as these may affect how Natrilix is processed by your body. If you experience any of the following symptoms, you may be dehydrated because you are losing too much water:
dry mouth or thirst
fainting
weakness
tiredness or drowsiness
muscle pain or cramps
fast heart beat
passing less urine than normal.

Things you must not do

Do not give this medicine to anyone else, even if they have the same condition as you.
Do not use Natrilix to treat any other complaints unless your doctor tells you to.
Do not stop taking Natrilix or change the dose, without checking with your doctor.

Things to be careful of

Be careful when driving or operating machinery until you know how Natrilix affects you.
You may feel light-headed or dizzy when you begin to take Natrilix. This is because your blood pressure is falling. Symptoms are likely to be made worse if you drink alcohol or take strong pain killers.
If you have these symptoms when standing up or getting out of bed then getting up more slowly can help. This allows your body to get used to the change in position and blood pressure.
Natrilix may cause your skin to become more sensitive to the sun. If this happens you should stop taking Natrilix and contact your doctor.
If you have these symptoms and they don't get better in a short time then talk to your doctor.

Unwanted effects potentially due to treatment

If you do not feel well while you are taking Natrilix then tell your doctor or pharmacist as soon as possible.
All medicines can have side effects. Most of the time they are not serious but sometimes they can be.
Natrilix helps most people with high blood pressure, but it may sometimes have unwanted side effects. These can include:
Headache.
Feeling tired or as if you have less energy, difficulty sleeping.
Feeling faint, light-headed, or dizzy.
Feeling nervous or anxious.
Feeling sick or having an upset stomach, having an uncomfortable feeling after eating, vomiting, constipation, diarrhoea or loss of appetite.
Muscle pain, back pain, joint pain, cramp or tingling or numbness of the hands or feet.
Skin rashes or other allergic reactions.
Gout.
Increased sensitivity to sunlight.
An increased risk of becoming dehydrated (in elderly patients and in patients with heart failure).
Low potassium levels. Symptoms of low potassium can include a number of those listed above, and very occasionally this may be severe.
Kidney disease.
Inflammation of the pancreas.
Hepatic encephalopathy (liver problems which affect the brain and central nervous system).
Abnormal liver function.
If you suffer from systemic lupus erythematosus (a type of collagen disease), this might get worse.
Changes in blood cells, such as thrombocytopenia (a decrease in the number of platelets which causes easy bruising and nasal bleeding), leucopoenia (a decrease of white blood cells which may cause unexplained fever, soreness of the throat or other flu-like symptoms) and anaemia (a decrease in red blood cells).
Low blood pressure, unusual heart beat.
Blurred or changed vision.
Dry mouth.
Cystitis.
Most of these side effects are mild when they occur. Do not be alarmed by this list of possible side effects. You may not experience any of them. However, if you do - or if you notice anything else that is making you feel unwell - you should consult your doctor or pharmacist.
If any of the signs below occur then tell your doctor immediately or go to the Accident and Emergency department at your nearest hospital:
Swelling of your lips, face, mouth, tongue or throat.
Purple spots with occasional blisters on the front of your arms and legs and/or around your neck and ears (A rare condition known as Stevens-Johnson Syndrome).
