What captopril is used for
The name of your medicine is Terry White Chemists Captopril. It contains the active ingredient, captopril.
Captopril is used to treat:
- high blood pressure (hypertension)
- heart failure
- patients who have had a heart attack
- kidney problems caused by diabetes.
These are long term (chronic) diseases so it is important that you continue to take your medicine every day.
How it works
Captopril 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.
By increasing the supply of oxygen to your heart, your heart does not have to work as hard which may reduce the risk of further damage to your heart after you have had a heart attack.
By reducing blood pressure, captopril may also slow down the kidney damage caused by type 1 (insulin-dependent) diabetes.
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), it 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 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.
A heart attack occurs when one of the major blood vessels supplying blood to your heart becomes blocked. This means that your heart can not receive the oxygen it needs and becomes damaged. This may lead to further problems, such as heart failure, irregular heart rhythms and blood clots.
Kidney Problems caused by Diabetes:
If you have type 1 (insulin-dependent) diabetes, you may develop kidney problems. The problems do not start at the same time as your diabetes is discovered; kidney problems develop slowly over several years. Good control of your blood sugar and blood pressure are important in keeping your kidneys healthy, but may not always prevent kidney damage from occurring.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed captopril for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that this medicine is addictive.
Use in children
Captopril is not recommended for use in children as there have not been enough studies of its effects in children. However, it may be necessary for a child with high blood pressure and kidney problems to take captopril. If this is the case, your doctor will discuss all possible risks and benefits to the child before starting therapy.
Before you take captopril

Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a
prescription from your pharmacy, supermarket or health food shop.
Some medicines and captopril may interfere with each other. These include:
- any other medicine used to treat high blood pressure
- water tablets or diuretics (e.g. Lasix®, Urex®, Natrilix®, Moduretic®)
- arthritis/osteoarthritis medicines which are called non-steroidal anti-inflammatory drugs (NSAIDs), or COX-2 inhibitors to relieve pain, swelling and other symptoms of inflammation (e.g. Brufen®, Indocid®, Naprosyn® or Celebrex®). Taking a combination of captopril with a thiazide diuretic (water tablet) and an anti-inflammatory medicine may damage your kidneys.
- potassium tablets (e.g. SPAN-K® SLOW-K® or K-MAG®)
- potassium containing salt substitutes (e.g.PRESSOR-K®)
- lithium, a medicine used to treat mood swings and some types of depression (e.g. Lithicarb®, Priadel®)
- medicines used to treat diabetes, including insulin
- antacids, medicines used to treat heartburn and indigestion
- general anaesthetics
- medicines used to treat gout, such as allopurinol
- medicines which lower the immune system, such as azathioprine or medicines used to treat cancer
- if you are taking captopril for high blood pressure do not take any medicine (including ones bought without a prescription) for appetite control, asthma, colds, coughs, hay fever or sinus problems unless you have discussed the medicine with your doctor or pharmacist.
These medicines may be affected by captopril, or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor and pharmacist can tell you if you are taking any of these medicines. They may also have more information on medicines to be careful with or avoid while taking captopril.
Other interactions not listed above may also occur.
How to take this medicine
Follow all directions given to you by your doctor or pharmacist carefully.
They may be different from the information contained in this leaflet.
If you do not understand any written instructions, ask your doctor or pharmacist for help.
How much to take
Your doctor or pharmacist will tell you how many tablets you will need to take. This depends on your condition and whether or not you are taking any other medicines.
Captopril is usually taken at a dose of 12.5 - 50 mg two or three times per day. Treatment may be started at low doses, particularly if you have heart failure. Your doctor will decide which dose is right for you.
How to take it
Swallow the tablets with a glass of water. Do not chew or crush the tablets.
When to take it
Your medicine should be taken on an empty stomach, preferably, one hour before food - alternatively, two hours after food, unless your doctor has prescribed otherwise.
If you need to take an antacid, take it at least two hours before or two hours after your dose of captopril.
How long to take it
Continue taking your medicine for as long as your doctor tells you.
Captopril 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.
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.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to the Accident and Emergency Department at the nearest hospital, if you think that you or anyone else may have taken too much captopril.
Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
If you take too much captopril, you may feel light-headed, dizzy or you may faint.
While you are taking captopril
Things you must do
If you become pregnant while taking captopril, 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 and salt and your blood pressure may drop too much. This is more likely to occur when you begin to take captopril or if your dose is increased.
Make sure you drink enough water during exercise and hot weather when you are taking captopril, especially if you sweat a lot.
If you do not drink enough water while taking captopril, you may feel faint, light-headed or sick. This is because your blood pressure may drop suddenly and you may dehydrate. If you experience any of the above symptoms, tell your doctor.
If you feel light-headed or dizzy after taking the first dose of your medicine, or when your dose is increased, tell your doctor immediately.
This is especially important if you are taking your medicine to treat heart failure.
Tell any other doctors, dentists and pharmacists who treat you that you are taking captopril.
If you are about to be started on a new medicine, tell your doctor, dentist or pharmacist that you are taking captopril.
If you plan to have surgery that needs a general anaesthetic, tell your doctor or dentist that you are taking captopril because having a general anaesthetic while taking captopril may cause your blood pressure to drop suddenly.
Your doctor may like to do blood tests to see how captopril is affecting you.
If you have blood tests, tell your doctor that you are taking captopril because captopril may interfere with the results of some tests.
Have your blood pressure checked when your doctor says, to make sure captopril is working.
Go to your doctor regularly for a check-up.
Your doctor may occasionally do a blood test to check your potassium levels and see how your kidneys are working.
Things you must not do
Do not give this medicine to anyone else, even if their symptoms seem similar to yours.
Do not take your medicine to treat any other complaints unless your doctor tells you to.
Do not stop taking your medicine, or change the dosage, without 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 captopril 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 captopril, especially if you are elderly.
Be careful driving or operating machinery until you know how captopril affects you.
If you drink alcohol, dizziness or light-headedness may be worse.
Things to do to help lower your blood pressure or help 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. Alsoeat 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.
