What Capoten is used for
Capoten is used for treating high blood pressure (hypertension), certain heart conditions, and certain kidney conditions associated with diabetes. These are long term (chronic diseases) so it is important that you continue to take your Capoten every day.
Capoten contains captopril. Captopril belongs to a class of medicines known as ACE inhibitors. ACE inhibitors work to lower your blood pressure to normal levels if it is too high. Capoten also acts to help your heart or kidneys to work better. Your doctor will tell you why you need to take Capoten. Never let anyone else take your medicine.
There is no evidence that it is addictive or habit forming.
This medicine is only available only with a doctor’s prescription.
Capoten is not recommended for use in children as there have been not enough studies of its effects in children. However it may be necessary for a child with hypertension and kidney problems to take this medicine, if this is the case your doctor will discuss all the possible risks and benefits to the child before starting therapy.
Before you take Capoten
When you must not take it
- you must not take Capoten if you are pregnant or may become pregnant
- medical conditions know as idiopathic angioedema or hereditary angioedema
- you must not take Capoten if you have ever had an allergy to Capoten or any of the ingredients listed at the end of this leaflet, or to another ACE inhibitor
Symptoms of an allergic reaction to Capoten may include
- shortness of breath, wheezing or difficulty breathing
- swelling of the face, lips, mouth, tongue or throat which may cause difficulty breathing or swelling of any other parts of the body
- rash, itching or hives on the skin
Do not take Capoten after the expiry date printed on the pack. If you take Capoten after this date or if Capoten starts to change in appearance, colour or taste, it may not work as well.
Before you start to take it
Before you take Capoten for the first time, tell your doctor if you:
- are pregnant or may become pregnant
- are breastfeeding or intend to breastfeed
- have any other medical problems, particularly diabetes, systemic lupus erythematous, scleroderma, neutropenia (low white blood cell count), have had a heart attack, heart failure, ischaemic heart disease or cerebrovascular disease
- take any other medicines or drugs, including any immunosuppressant medicine
- have had an allergy to Capoten or any of its additives, or to another ACE inhibitor
- have kidney disease, a single kidney or are undergoing dialysis
- liver disease now or in the past
- are dehydrated, have had a recent bout of vomiting or diarrhoea or are taking a diuretic medicine (water tablets)
Taking other medicines
Some medicines can affect the way Capoten works.
You should always tell your doctor about any other medicines that you take, even if you have bought the medicines without a doctor’s prescription. It is especially important that you tell your doctor if you are taking any of the following:
- water tablets or diuretics (for example Lasix®, Urex®, Natrilix®, Moduretic®)
- lithium or lithium-containing preparations (for example Lithicarb®, Priadel®)
- potassium tablets (for example SPAN-K®, SLOW-K® or K-MAG®)
- potassium-containing salt substitutes (for example PRESSOR-K®)
- any other medicine for high blood pressure
- any medicine for angina
- if you are taking Capoten 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.
- anti-inflammatory medicines (these are used to relieve pain, swelling and other symptoms of inflammation, including arthritis) and include nonsteroidal anti-inflammatory agents – NSAIDs (for example Voltaren, Indocid) and COX-2 inhibitors (for example Celebrex).
Taking a combination of Capoten with a thiazide diuretic (fluid tablet) and an anti-inflamatory medicine may damage your kidneys.
Your doctor will decide whether your treatment needs to be altered or whether you should have check ups or blood tests more frequently.
How to take it
How much to take
Capoten is usually taken at a dose of 12.5 to 50mg two or three times per day. Treatment may be started with low doses of Capoten, particularly if you have heart failure. Your doctor will decide which dose is right for you.
How to take it
Swallow your tablets with a glass of water.
When to take it
Preferably take Capoten one hour before meals.
If you forget to take it
If you forget to take one or more doses: take your next dose at the normal time and in the normal amount. Do not take a double dose to make up for the dose you missed. This may increase the chance of you getting an unwanted side effect.
Ask your doctor or pharmacist if you are not sure what to do.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
How long to take it
Capoten is used to treat long term (chronic) diseases, so it is important to continue taking Capoten every day until your doctor tells you to stop.
Do not stop taking your tablets because you are feeling better.
If you take too much (Overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to casualty at your nearest hospital, if you think that you or any one else may have taken too much Capoten. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention
While you are using Capoten
Things you must do
- If you become pregnant while taking Capoten tell your doctor immediately
- Have your blood pressure checked when your doctor tells you to, to make sure the medicine is working
- If you are about to start on any new medicine, tell your doctor and pharmacist that you are taking Capoten.
- If you plan to have surgery (even at the dentist) that needs an anaesthetic, or are having some other hospital treatment, make sure that you tell your doctor or dentist that you are taking this medicine
Make sure you drink enough water during exercise and hot weather when you are taking it, especially if you sweat a lot
If you do not drink enough water while taking Capoten, you may faint or feel light-headed or sick. This is because your body does not have enough fluid and your blood pressure is low. If you continue to feel unwell, tell your doctor.
If you have excessive vomiting and/or diarrhoea while taking Capoten, tell your doctor
This can also mean that you are losing too much water and your blood pressure may become too low.
- Have any blood tests that your doctor asks you to

Be careful driving or operating machinery until you know how this medicine affects you. As with other ACE inhibitors, Capoten can cause dizziness or lightheadedness in some people, especially after the first dose. Make sure you know how Capoten affects you before you drive a car or operate machinery, or do any thing else that could be dangerous if you are dizzy or light-headed. If this occurs do not drive.
