What AMPRACE is used for
AMPRACE lowers high blood pressure, which doctors call hypertension. It is also used to treat heart failure.
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) 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. AMPRACE helps to lower
your blood pressure.
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.
AMPRACE helps to treat heart failure, whether you have symptoms or not. In many patients with heart failure who have symptoms,
AMPRACE may slow the progression of heart failure and reduce the need to go to hospital as a result of heart failure. AMPRACE
may help some of these patients live longer.
In many patients with heart failure who have no symptoms, AMPRACE may help to stop the heart muscle from getting weaker.
AMPRACE may also slow down the development of symptoms, such as shortness of breath, tiredness after light physical activity,
or swelling of the ankles and feet. These patients may be less likely to have hospital stays due to heart failure.
By taking AMPRACE, heart failure patients may have less chance of having a heart attack.
When used to treat heart failure, AMPRACE 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.
How AMPRACE works
One of the ways AMPRACE helps lower blood pressure and treat heart failure is that it widens blood vessels. This means that
blood is able to pass through them more easily and the heart doesn't have to pump as hard to move 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.
AMPRACE belongs to a group of medicines called Angiotensin Converting Enzyme (ACE) inhibitors.
Your doctor may prescribe AMPRACE for another reason. Ask your doctor if you have any questions about why AMPRACE has been
prescribed for you.
AMPRACE is not addictive.
Before you take AMPRACE
When you must not take it
Do not take AMPRACE if:
you have taken any other 'ACE inhibitor' medicines for high blood pressure or heart failure before, which caused your face,
lips, tongue, throat, hands or feet to swell up, or made it hard for you to breathe
If you have had an allergic reaction to an ACE inhibitor before, you may be allergic to AMPRACE.
you have an allergy to AMPRACE or other brands of enalapril maleate, such as Renitec®, or any of the ingredients listed at the end of this leaflet
Symptoms of an allergic reaction to AMPRACE may include skin rash, itchiness, shortness of breath, swelling of the face, lips
or tongue, muscle pain or tenderness or joint pain.
you have a history of swelling of the face, lips, tongue, throat, hands or feet, for no apparent reason.
you have diabetes and are taking a medicine called aliskiren to reduce blood pressure.
Do not take AMPRACE if you are pregnant or breast-feeding.
Your baby may absorb this medicine in the womb or from breast milk and therefore there is a possibility of harm to the baby.
Do not take AMPRACE if:
the packaging is torn or shows signs of tampering
the expiry date on the pack has passed.
If you take this medicine after the expiry date has passed, it may not work.
If you are not sure whether you should start taking AMPRACE, talk to your doctor.
Before you start to take it
Tell your doctor if:
you are or intend to become pregnant or intend to breast-feed
AMPRACE should not be used during pregnancy or while breast-feeding.
you have any medical conditions, especially the following:
kidney disease, or are undergoing dialysis
you have recently suffered from excessive vomiting or diarrhea
you are following a very low salt diet
you have had an allergy to any other medicines or any other substances, such as foods, preservatives or dyes.
if you suffer from low blood pressure (you may notice this as faintness or dizziness, especially when standing).
surgery and anaesthesia (even at the dentist office) are scheduled, as there may be a sudden fall in blood pressure associated
If you have not told your doctor about any of the above, tell them before you take any AMPRACE.
Taking other medicines
Tell your doctor if you are taking any other medicines, including medicines that you buy without a prescription from your
pharmacy, supermarket or health food shop. Some medicines and AMPRACE may interfere with each other. These include:
other blood pressure medicines
diuretic tablets - also called fluid or water tablets
lithium, a medicine used to treat mood swings and some types of depression
potassium-containing salt substitutes
potassium-sparing agents (e.g. spironolactone, eplerenone, triamterene, amiloride)
non-steroidal anti-inflammatory medicines (NSAIDs or Coxibs/COX-2 inhibitors), used to relieve pain, swelling and other symptoms
arthritis medicines including gold therapy
insulin or oral antidiabetic medicines. You should be closely monitored for low blood glucose levels, especially during the
first month of treatment with AMPRACE.
These medicines may be affected by AMPRACE, or may affect how well it works. You may need to take different amounts of your
medicine, or you may need to take different medicines.
Your doctor or pharmacist has more information on medicines to avoid while taking AMPRACE.
How to take AMPRACE
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. Take AMPRACE only when prescribed by your doctor.
For high blood pressure:
For most patients, the usual starting dose is 5 mg taken once a day. Some patients may need a lower starting dose. The dose
may need to be increased depending on your blood pressure. Most patients take between 10 to 40 mg each day.
For heart failure:
The usual starting dose is 2.5 mg taken once a day. Depending on your response, this dose may need to be increased up to
20 mg each day. This dose may be taken once a day or divided into two doses per day.
Follow all directions given to you by your doctor carefully.
They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How to take it
Take your AMPRACE at about the same time each day.
Taking your tablet(s) at the same time each day will have the best effect. It will also help you remember when to take the
Swallow AMPRACE with a glass of water.
It does not matter if you take AMPRACE before or after food.
How long to take it
AMPRACE helps control your high blood pressure and helps improve your heart failure, but does not cure it. Therefore AMPRACE
must be taken every day. Continue taking AMPRACE for as long as your doctor prescribes.
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 tablet(s) as you would normally.
If you are not sure whether to skip the dose, talk to your doctor or pharmacist.
Do not take a double dose to make up for the dose that you missed.
If you have trouble remembering to take your tablets, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to accident and emergency at your
nearest hospital, if you think that you or anyone else may have taken too much AMPRACE. Do this even if there are no signs
of discomfort or poisoning.
If you take too many tablets, you will probably feel light-headed or dizzy, or you may faint.
While you are using AMPRACE
Things you must do
Have your blood pressure checked when your doctor says, to make sure AMPRACE is working.
If you feel any light-headedness or dizziness after you take your first dose of AMPRACE or if your dose is increased, tell
your doctor immediately. This is especially important if you are taking AMPRACE for heart failure.
If you feel light-headed, dizzy or faint, get up slowly when getting out of bed or standing up.
You may feel light-headed or dizzy, especially if you are also taking a diuretic (fluid tablet). This may be because your
blood pressure is falling suddenly. 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 this problem gets worse or continues, talk to your doctor.
If you become pregnant while taking AMPRACE, tell your doctor immediately.
If you are about to be started on any new medicine tell your doctor and pharmacist that you are taking AMPRACE.
If you plan to have surgery (even at the dentist) that needs a general anaesthetic, tell your doctor or dentist that you are
Your blood pressure may drop suddenly.
Make sure you drink enough water during exercise and hot weather when you are taking AMPRACE, especially if you sweat a lot.
If you do not drink enough water while taking AMPRACE, you may faint or feel light-headed or sick. This is because your blood
pressure is dropping suddenly. If you continue to feel unwell, tell your doctor.
If you have excessive vomiting and/or diarrhoea while taking AMPRACE, tell your doctor.
This can also mean that you are losing too much water and salt, and may drop your blood pressure too much.
Go to your doctor regularly for a check-up.
Your doctor may occasionally do a blood test to check your potassium level in the blood and to see how your kidneys are working.
Things you must not do
Do not give AMPRACE to anyone else, even if they have the same condition as you.
Things to be careful of
Be careful driving or operating machinery until you know how AMPRACE affects you.
AMPRACE may cause dizziness or light-headedness in some people, especially after the first dose or if the dose is increased.
Make sure you know how you react to AMPRACE 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, dizziness or light-headedness may be worse.
Things that would be helpful for your blood pressure or heart failure
Some self help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and
for more information.
your doctor may advise you to limit your alcohol intake.
eat a healthy diet which includes plenty of fresh vegetables, fruit, bread, cereals and fish. Also eat less fat and sugar.
regular exercise helps to reduce blood pressure and helps the heart get fitter, but it is important not to overdo it. Walking
is good exercise, but try to find a route that is fairly flat. Before starting any exercise, ask your doctor about the best
kind of programme for you.
your doctor may advise you to watch the amount of salt in your diet. To reduce your salt intake you should avoid using salt
in cooking or at the table.
your doctor may advise you to stop smoking or at least cut down.
your doctor may suggest losing some weight to help lower your blood pressure and help lessen the amount of work your heart
has to do. Some people may need a dietician's help to lose weight.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking AMPRACE.
AMPRACE helps most people with high blood pressure and heart failure, but it may have unwanted side effects in a few people.
All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment
if you get some of the side effects.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
light-headedness or dizziness because blood pressure is too low
mild stomach upsets such as feeling sick, diarrhoea, or stomach pains
