What MODURETIC is used for
MODURETIC contains a combination of two diuretics, amiloride hydrochloride and hydrochlorothiazide as the active ingredients.
MODURETIC is used to help reduce the amount of excess fluid in the body for people who have:
- oedema, swelling of the ankles, feet and legs
- ascites due to liver disease resulting in fluid accumulation in the stomach area.
MODURETIC is also used to help people with hypertension or high blood pressure.
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 or high blood pressure when your blood pressure stays higher than is needed, 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 and kidney failure.
The combination of active ingredients in MODURETIC work by making your kidneys pass more water and salt whilst minimizing potassium loss. This helps reduce high blood pressure and some forms of swelling, while at the same time helping to maintain normal levels of potassium in your blood.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another purpose.
This medicine is only available with a doctor's prescription.
There is no evidence that it is addictive.
Before you take it
When you must not take it
Do not take MODURETIC if you have ever had an allergic reaction to:
- amiloride hydrochloride
- hydrochlorothiazide, sulfonamide or sulfur medicines
Hydrochlorothiazide is a sulfur-containing medicine (a sulfonamide). Therefore, if you are allergic to sulfur medicines, such as some antibiotics, you are likely to be allergic to MODURETIC.
Check with your doctor or pharmacist if you are not sure whether you are allergic to sulfur medicines.
- any of the ingredients listed at the end of this leaflet.
Symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty in breathing; swelling of the face, lips, tongue or any other parts of the body; rash, itching or hives on the skin.
Do not take MODURETIC if you are pregnant or intend to become pregnant unless you and your doctor have discussed the risks and benefits involved.
It may affect your developing baby if you take it during pregnancy.
Do not take MODURETIC if you are breast-feeding or intend to breast-feed.
This medicine can pass into breast milk and therefore may harm the baby.
Do not take MODURETIC if:
- you have kidney disease
- your doctor advises you that you have too much potassium in your blood
- you are taking medicines which can increase the amount of potassium in the blood or you are eating a potassium-rich diet.
MODURETIC helps maintain normal levels of potassium in your blood. If you are taking potassium tablets or supplements, other potassium-conserving medicines or a potassium-rich diet, your potassium levels may increase too much.
Ask your doctor or pharmacist if you are not sure whether you are taking any of these.
Do not give MODURETIC to a child.
The safety of MODURETIC in children has not been established.
Do not take MODURETIC if the packaging is torn or shows signs of tampering.

How to take it
How 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. Your initial dose will be maintained or adjusted until a satisfactory response is noted, but should not exceed 4 tablets per day.
Follow all directions given to you by your doctor and pharmacist carefully.
They may differ from the information contained in this leaflet.
When to take it
If you are taking a single dose a day, take it in the morning. If you are taking more than one dose a day, take the last dose in the early evening, unless your doctor tells you otherwise.
MODURETIC may increase the amount of urine you pass and the number of times you go to the toilet. By taking the last dose in the early evening there may be less chance of your sleep being disturbed.
Take MODURETIC at about the same time each day, unless your doctor tells you otherwise.
This will help you remember when to take the tablets.
How long to take it
Continue taking MODURETIC for as long as your doctor tells you.
If you have high blood pressure, this medicine helps to control this condition but does not cure it. Therefore MODURETIC must be taken every day.
If you have oedema or ascites, your doctor will tell you how long to take it.
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 medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre on 13 11 26 (Australia) or 0800 POISON or 0800 764 766 (New Zealand) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much MODURETIC. Do this even if there are no signs of discomfort or poisoning.
You may need medical attention.
While you are taking it
Things you must do
Visit your doctor regularly for a blood pressure test so they can make sure that MODURETIC is working properly and to check for any unwanted side effects.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
You may feel light-headed or dizzy when you begin to take MODURETIC. This is because your blood pressure is falling suddenly.
If this problem 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 MODURETIC.
Tell any other doctor, dentist of pharmacist who is treating you that you are taking MODURETIC, especially if you are about to be started on any new medicines.
Tell your doctor if you become pregnant while taking MODURETIC.
Things to be careful of
Be careful driving or operating machinery until you know how this medicine affects you.
MODURETIC may cause dizziness or light-headedness in some people, especially after the first few doses or if the dose is increased. Make sure you know how you react to it 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, or take strong pain killers or barbiturates, dizziness and light-headedness may be worse.
Talk to your doctor about foods or drinks that have a high potassium content.
MODURETIC helps to maintain normal potassium levels in your body. However, if you eat foods or have drinks that are high in potassium this may lead to an increase of potassium in your body. Too much potassium can be harmful, therefore it is important to discuss your diet with your doctor.
Tell your doctor if you are being treated for diabetes.
MODURETIC may change how well your diabetes is controlled. Your doses of diabetic medicines, including insulin, may need to change.
