Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Odaplix SR.

What is in this leaflet

This leaflet answers some common questions about ODAPLIX SR. It does not contain all the available information about this medicine. Reading this leaflet does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking ODAPLIX SR against the expected benefits for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What ODAPLIX SR is

The name of your medicine is ODAPLIX SR. The medicine releases the active ingredient indapamide progressively over 24 hours. Indapamide belongs to a group of medicines called chlorosulfamoyl diuretics (a type of "fluid" or "water" tablet).

What ODAPLIX SR is used for

You have been prescribed ODAPLIX SR for high blood pressure.

ODAPLIX SR is available only with a doctor's prescription.

There is no evidence that ODAPLIX SR is addictive.

Why ODAPLIX SR 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.

ODAPLIX SR helps to lower your blood pressure.

Ask your doctor if you have any questions about why ODAPLIX SR has been prescribed for you.

Before you take ODAPLIX SR

There are some people who should not take ODAPLIX SR. Please read the lists below. If you think any of these situations apply to you, or you have any questions, please consult your doctor or pharmacist.

How to take ODAPLIX SR

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 ODAPLIX SR 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 ODAPLIX SR for

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

If you forget to take ODAPLIX SR

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 ODAPLIX SR

Taking too much ODAPLIX SR (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 ODAPLIX SR 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 ODAPLIX SR

Things you must do

Take ODAPLIX SR 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 ODAPLIX SR.

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 ODAPLIX SR as these may affect how ODAPLIX SR 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 heartbeat
  • 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 ODAPLIX SR to treat any other complaints unless your doctor tells you to.

Do not stop taking ODAPLIX SR 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 ODAPLIX SR affects you. You may feel light-headed or dizzy when you begin to take ODAPLIX SR. 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.

ODAPLIX SR may cause your skin to become more sensitive to the sun. If this happens you should stop taking ODAPLIX SR 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 ODAPLIX SR 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.

ODAPLIX SR 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 or constipation.
  • Muscle weakness, pain, tenderness, cramp, tingling or numbness of the hands or feet (and particularly if at the same time you feel unwell or have a high temperature it may be caused by an abnormal muscle breakdown (not known)).
  • 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)
  • 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 heartbeat.
  • High level of calcium in blood
  • Blurred or changed vision, short sightedness (myopia).
  • Decrease in vision or pain in your eyes due to high pressure (possible signs of fluid accumulation in the vascular layer of the eye or acute angle-closure glaucoma).
  • Dry mouth.
  • Cystitis.
  • Erectile dysfunction.

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.

Changes may occur in your laboratory parameters (blood tests) and your doctor may need to give you blood tests to check your condition. The following changes in laboratory tests may occur: low potassium, magnesium, chloride or sodium in the blood. Low sodium may lead to dehydration and low blood pressure. Increase in uric acid (a substance which may cause or worsen gout), increase in blood glucose levels in diabetic patients, increased levels of liver enzymes.

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).
  • Toxic epidermal necrolysis.
  • A fast and irregular heartbeat.
  • Severe blisters, skin rash, itching or other allergic reactions.

These side effects are extremely rare but can become serious.

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. No data available.
Carcinogenicity. Carcinogenicity studies in mice and rats showed no evidence of tumourigenicity when indapamide was administered in the diet at levels up to 100 mg/kg/day.
Mutagenicity. Indapamide was negative in mutagenicity tests in bacteria, and bone marrow micronucleus tests in mice.
There was a decrease in weight gain of the F1 generation from rats treated orally at 2.5 mg/kg/day. Galactopoiesis was affected in the F1 generation from rats treated orally at 0.5 mg/kg/day and this led to increased mortality of the F2 generation during the first 48 hours of life. No embryofoetal toxicity or teratogenic potential were seen in rats (up to 150 mg/kg/day) and in rabbits (up to 180 mg/kg/day).
