What this medicine is used for
Quinapril is used to lower high blood pressure (also known as hypertension) and treat
High blood pressure:
Everyone has blood pressure. Blood pressure helps to move your blood all around your
body. Your blood pressure may be different at different times of the day and may be
affected by how busy or worried you are. You have 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 high blood pressure. The only way of knowing that
you have high blood pressure 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.
How it works
Quinapril belongs to a group of medicines called angiotensin converting enzyme (ACE)
Quinapril works by widening your blood vessels, which reduces pressure in the vessels
and makes it easier for your heart to pump blood around your body. This increases
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

How long to take it

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.

Tell your doctor or dentist if you are going to have surgery or an anaesthetic or

Your blood pressure may drop suddenly.
Tell your doctor if you are about to have any blood tests.
Quinapril may interfere with the results of some tests as it can result in sodium
blood levels that are lower than the normal limits.
Keep all of your doctor's appointments so that your progress can be checked.
Your doctor may occasionally do a blood test to check your potassium levels and see
how your kidneys are working.
Tell your doctor if you have experienced excess vomiting or diarrhoea.
You may lose too much water and salt and your blood pressure may drop too much.
Tell your doctor if you feel light-headed or dizzy after taking your first dose or
when your dose is increased.
Make sure you drink enough water during exercise and hot weather when you are taking
quinapril, especially if you sweat a lot.
If you do not drink enough water while taking quinapril, you may feel faint, light-headed
or sick. This is because your blood pressure is dropping suddenly. If you continue
to feel unwell, tell your doctor.
Things you must not do
Do not give this medicine to anyone else, even if they have the same condition as
Do not take your medicine to treat any other complaints unless your doctor tells you
Do not stop taking your medicine or change the dosage without first checking with
Things to be careful of
Be careful driving or operating machinery until you know how this medicine affects
As with other ACE inhibitor medicines. Quinapril may cause dizziness, light-headedness
or tiredness in some people. If you have any of these symptoms, do not drive, operate
machinery or do anything else that could be dangerous. If you drink alcohol, dizziness
or light-headedness may be worse.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get
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 continues
or gets worse, talk to your doctor.
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 diet which includes plenty of fresh vegetables, fruit, bread (preferably
wholegrain), cereals and fish. Also eat less sugar and fat (especially saturated fat)
which includes sausages, fatty meats, full cream dairy products, biscuits, cakes,
pastries, chocolates, chips and coconut. Monounsaturated and polyunsaturated fats
from olive oil, canola oil, avocado and nuts are beneficial in small quantities.
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 and avoid cooked
or processed foods containing high sodium (salt) levels.
Regular exercise, maintained over the long term, helps reduce blood pressure and helps
get the heart fitter. Regular exercise also improves your cholesterol levels, helps
reduce your weight and stress levels, and improved your sleep, mood and ability to
concentrate. However, it is important not to overdo it. 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. Ask your doctor or
pharmacist for further information and advice.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you
are taking quinapril.

this reason, it is important to tell your doctor of any change in your condition.
