What this medicine is used for

The name of your medicine is Terry White Chemists Enalapril. It contains the active ingredient enalapril.

It is used to treat:

  • high blood pressure
  • 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.

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, including stroke, heart disease and kidney failure.

Heart Failure:
Heart failure means that the heart muscle is weak and 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 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.

Your doctor may have prescribed enalapril for another reason.

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

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

How it works

Enalapril 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.

This medicine is not addictive.

Use in children

There is not enough information to recommend the use of this medicine in children.

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.

For High Blood Pressure (Hypertension):
For most patients, the usual starting dose is 5 mg taken once a day. Some patients may need a lower starting dose. Most patients take between 10 mg to 40 mg each day. This dose may be taken once a day or divided into two doses per day.

For Heart Failure:
The usual starting dose is 2.5 mg taken once a day. Depending on your response, this dose may be increased up to 20 mg each day. This dose may be taken once a day or divided into two doses per day.

How to take it

Swallow the tablets with a glass of water. Do not chew or crush the tablets.

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.

How long to take it for

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

This medicine helps to control your condition but does not cure it. It is important to keep taking your medicine every day, even if you feel well.

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

If you become pregnant while taking this medicine, tell your doctor immediately.

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 enalapril or if your dose is increased.

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

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

Tell your doctor that you are taking this medicine if:

  • you are about to be started on any new medicine
  • you are breastfeeding or are planning to breast-feed
  • you are going to have surgery or an anaesthetic or are going into hospital.

Having a general anaesthetic while taking enalapril may cause your blood pressure to drop suddenly.

  • you are about to have any blood tests

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 enalapril 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 enalapril, especially if you are elderly.

Be careful driving or operating machinery until you know how enalapril affects you.

As with other ACE inhibitor medicines, enalapril may cause dizziness or light-headedness in some people. Make sure you know how you react to enalapril before you drive a car, operate machinery or do anything else that could be dangerous if you are dizzy or light-headed. If this occurs do not drive

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.

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.

Eat a healthy low-fat diet which includes plenty of fresh vegetables, fruit, bread, cereals and fish. Also eat less fat and sugar.

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.

Regular exercise helps to reduce blood pressure and helps to get the heart fitter, but it is important not to overdo it. Walking is good exercise, but try to find a route that is reasonably flat. Before starting any exercise, ask your doctor about the best kind of programme for you.

Your doctor may advise you to stop smoking or at least cut down.
