What this medicine is used for

The name of your medicine is APO-Fosinopril. It contains the active ingredient fosinopril.

It is used to treat:

  • high blood pressure (hypertension)
  • heart failure.

Both of these are long term (chronic) diseases so it is important that you continue to take your medicine every day.

High blood pressure (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.

If you have hypertension (high blood pressure), this means that your blood pressure stays higher than is needed, even when you are 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, including stroke, heart disease and kidney failure.

Heart Failure:

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. Heart failure may start off with no symptoms, but as the condition progresses, patients 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.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

This medicine is available only with a doctor’s prescription.

How it works

Fosinopril belongs to a class of medicines known as Angiotensin Converting Enzyme (ACE) inhibitors. It works by widening your blood vessels, reducing the pressure in the vessels (reducing ‘blood pressure’) and by making it easier for your heart to pump blood around your body. This helps your heart to work better by increasing the supply of oxygen to your heart, so that when you place extra demands on your heart, such as during exercise, your heart may cope better and you may not get short of breath as easily.

There is no evidence that this medicine is addictive.

Use in children

This medicine should not be used in children.

Taking other medicines

Some medicines may interact with fosinopril. These include:

  • water tablets or diuretics (for example frusemide, indapamide, amiloride and hydrochlorothiazide)
  • potassium tablets (for example potassium chloride
  • potassium-containing salt substitutes
  • angiotensin II receptor blockers (e.g. irbesartan, valsartan, telmisartan) or aliskiren-containing medications
  • diabetes medication
  • lithium or lithium-containing preparations (for example lithium carbonate)
  • antacids
  • if you are taking fosinopril for high blood pressure do not take any medicine (including ones bought without prescription) for appetite control, asthma, colds, coughs, hayfever or sinus problems unless you have discussed the medicine with your doctor
  • anti-inflammatory medicines (these are used to relieve pain, swelling and other symptoms of inflammation, including arthritis) and include non-steroidal anti-inflammatory agents – NSAIDS (for example diclofenac and aspirin) and COX-2 inhibitors (for example celecoxib). Taking a combination of fosinopril with a thiazide diuretic (water tablet) and an anti-inflammatory medicine may damage your kidneys
  • medicines that lower your immune system, such as medicines used to prevent rejection of transplant organs
  • trimethoprim containing medicines used to treat certain types of injections
  • injectable gold or sodium aurothiomalate.

If you are taking any of these you may need a different dose or you may need to take different medicines.

How to take this medicine

Follow carefully all directions given to you by your doctor. Their instructions may be different to the information in this leaflet.

How much to take

Your doctor will tell you how much of this medicine you should take. This will depend on your condition and whether you are taking any other medicines.

Do not stop taking your medicine or change your dosage without first checking with your doctor.

How to take it

Most people will initially start taking a 10 mg dose once daily. Fosinopril is then usually taken at a dose of 10 mg to 40 mg once a day. Your doctor may have prescribed a different dose for you.

When to take it

Take this medicine at the same time each day. Taking it at the same time each day will have the best effect and will also help you remember when to take it.

It does not matter if you take it before, with or after food.

If you need to take an antacid, take it at least 2 hours before or 2 hours after your dose of fosinopril.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.

Make sure you have enough to last over weekends and holidays.

If you forget to take it

If it is almost time to take your next dose, skip the missed dose and take your next dose at the usual time. 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 missed doses. This may increase the chance of you experiencing side effects.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency Department at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are taking this medicine

Things you must do

Tell your doctor that you are taking this medicine if:

  • you are about to be started on any new medicine
  • you are pregnant or are planning to become pregnant
  • you are about to have any blood tests
  • you are going to have surgery or an anaesthetic or are going into hospital.

Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects.

Tell your doctor if you have excessive vomiting or diarrhoea or experience any of the following symptoms:

  • light-headed or dizzy
  • dry mouth or thirst
  • weakness, tiredness or drowsiness
  • muscle pain or cramps
  • fast heart beat
  • passing less urine than normal.

If you experience these symptoms, you may be dehydrated because you are losing too much water. This is more likely to occur when you begin to take fosinopril or if your dose is increased.

Make sure you drink enough water during exercise and hot weather when you are taking fosinopril, especially if you sweat a lot.

If you do not drink enough water while taking fosinopril, your blood pressure may drop suddenly and you may dehydrate. If you experience any of the above symptoms, tell your doctor.

Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects. Go to your doctor regularly for a check-up.

Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.

Things you must not do

Do not:

  • Give this medicine to anyone else, even if their symptoms seem similar to yours
  • Take your medicine to treat any other condition unless your doctor tells you to
  • Stop taking your medicine, or change the dosage, without first checking with your doctor.

Things to be careful of

As with other ACE inhibitor medicines, you may feel light-headed or dizzy when you begin to take fosinopril or after your dose is increased. This is because your blood pressure is dropping suddenly.

If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.

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. Be careful the first time you take fosinopril, especially if you are elderly.

Be careful when driving or operating machinery until you know how this medicine affects you.

If you drink alcohol, dizziness or light-headedness may be worse.

Possible side effects

Tell your doctor as soon as possible if you do not feel well while you are taking fosinopril or if you have any questions or concerns.

Do not be alarmed by the following lists of side effects. You may not experience any of them. All medicines can have side effects. Sometimes they are serious but most of the time they are not.

  • feeling sick (nausea) or vomiting
