1. What Quinapril is and what it is used for
Quinapril belongs to a group of drugs called Angiotensin Converting Enzyme (ACE) Inhibitors. This
medicine works by widening the blood vessels, making it easier for the heart to pump blood around the body.
This helps to lower blood pressure.
Quinapril is used:
• in the treatment of high blood pressure.
• in the treatment of heart failure (a condition when your heart is not coping with its workload
2. What you need to know before you take Quinapril
Do not take Quinapril
If you are allergic to quinapril or any of the other ingredients of this medicine (listed in section 6).
If you have ever experienced an allergic reaction to another ACE-inhibitor drug e.g, captopril, ramipril,
which has led to swelling of hands, lips, tongue or throat.
If you have ever been diagnosed with a condition known as hereditary angioedema (rapid swelling of the
face, tongue or throat).
If you are more than 3 months pregnant (it is also better to avoid Quinapril in early pregnancy – see
section ‘Pregnancy and breast-feeding’).
If you have an obstruction in your heart that slows blood in the heart.
If you have diabetes or impaired kidney function and you are treated with a blood pressure lowering
medicine containing aliskiren.
Warnings and precautions
Talk to your doctor or pharmacist before taking Quinapril
If you have aortic stenosis (narrowing of the main blood vessel from the heart)
If you suffer from allergies or asthma
If you may be dehydrated, for example, you have suffered from excessive vomiting or diarrhoea recently
or are on a low salt diet.
If you suffer from kidney problems, including narrowing of the blood vessels leading to you kidneys, or
you are on dialysis, or have had a kidney transplant.
If you suffer from liver problems.
If you are about to have a treatment called ‘LDL apheresis’, which is the removal of cholesterol from
your blood by a machine.
If you are to undergo any desensitisation treatment to reduce the effects of an allergic condition.
If you suffer from a collagen vascular disease such as lupus erythematosus.
If you suffer from a condition called ‘hyperaldosteronism’ (excess of aldosterone hormone is produced).
If you have diabetes.
If you are going to have an anaesthetic (even at the dentist) or undergo any surgery.
If you are a black patient, this medicine might not work as well for you or you might be more likely to
suffer serious side effects (e.g. angioedema- swelling of the face, eyes, tongue or throat).
If you are taking any of the following medicines used to treat high blood pressure:
- an angiotensin II receptor blocker (ARBs) (also known as sartans – for example valsartan,
telmisartan, irbesartan), in particular if you have diabetes-related kidney problems.
If you are taking any of the following medicines, the risk of angioedema (rapid swelling under the skin in
area such as the throat) is increased:
- sirolimus, everolimus and other medicines belonging to the class of mTOR inhibitors (used to avoid
rejection of transplanted organs)
Your doctor may check your kidney function, blood pressure, and the amount of electrolytes (e.g. potassium)
in your blood at regular intervals.
See also information under the heading ‘Do not take Quinapril’.
You must tell your doctor if you think you are, or might become, pregnant. Quinapril is not recommended in
early pregnancy, and must not be taken if you are more than 3 months pregnant, as it may cause serious
harm to your baby if used at that stage (see section ‘Pregnancy and breast-feeding’).
Quinapril can cause cough, talk to your doctor if you develop a dry, persistent cough.
Quinapril can cause changes in your blood test results. Talk to your doctor if you develop a severe sore
throat or severe mouth ulcers, particularly if you suffer from kidney problems or collagen vascular disease.
This may mean you do not have enough of certain white blood cells (neutropenia/agranulocytosis), which
may lead to an increased risk of infection or fever.
Other medicines and Quinapril
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, in
Diuretics (also known as water tablets) e.g amiloride, spironolactone or triamterene, as the risk of low
blood pressure may be increased.
Medicines which are most often used to avoid rejection of transplanted organs (sirolimus, everolimus
and other medicines belonging to the class of mTOR inhibitors). See section “Warnings and
Potassium supplements (this includes salt substitutes that often contain potassium), other drugs which
can increase potassium in your body (such as heparin and co-trimoxazole also known as

the risk of low blood pressure may be increased.
Procainamide (used to treat some heart conditions).

How to take Quinapril
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or
pharmacist if you are not sure.
The tablets should be swallowed preferably with a drink of water. The tablets should usually be taken once a
day, in the morning, but your doctor may ask you to take them twice a day e.g. in the morning and in the
evening. The recommended dose is:
High Blood Pressure:
The recommended starting dose is 10 mg once daily. Your doctor may, if necessary, increase your dose to 20
or 40 mg a day, taken as one or two doses.
If you are already taking a diuretic (water tablet), your doctor may recommend an initial dose of 2.5 mg once
daily, gradually increasing this as necessary. Your doctor may have told you to stop taking your diuretic
medicine 2 or 3 days before starting Quinapril. Your doctor will adjust your dose to suit you.
For heart failure the recommended starting dose is 2.5 mg once daily. After this, your doctor will gradually
increase your dose over 2 to 3 weeks to reach an effective dose. The maximum dose is 40mg a day, taken as
one or two doses.
Occasionally some people need higher doses than those stated above.
Older people or patients with kidney problems:
If you are older people or have kidney problems the dose may be lower. An initial dosage in high blood
pressure of 2.5 mg is recommended. Your dose will then be adjusted by your doctor.
Use in children and adolescents
Efficacy and safety of use in children and adolescents has not been established. Use in children and
adolescents is therefore not recommended.
If you take more Quinapril than you should
If you (or someone else) swallow a lot of the tablets all together or if you think a child has accidentally
swallowed any of the tablets, contact your nearest hospital casualty department or your doctor
An overdose can cause very low blood pressure leading to dizziness and fainting; weak pulse and clammy
skin; stupor, a slow heart beat, chemical imbalance in the body fluids and kidney failure.
Please take this leaflet, any remaining tablets, and the container with you to the hospital or doctor so that
they know which tablets were consumed.
If you forget to take Quinapril
If you forget to take a tablet, take one as soon as you remember, unless it is nearly time to take the next one.
Do not take a double dose to make up for a forgotten tablet. Take the remaining doses at the correct time.
If you stop taking Quinapril
Do not stop taking your medicine without talking to your doctor first, even if you feel better.
If you see another doctor or go into a hospital, let him or the staff know what medicines you are taking.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
If the following occurs, stop taking Quinapril and tell your doctor immediately or go to the casualty
department at your nearest hospital:
swelling of the lips, face and neck, leading to severe difficulty breathing; severe skin rash or hives. This is a
very serious but very rare side effect. You may need urgent medical attention or hospitalisation.
You may feel dizzy, light-headed or have visual problems for a short time after you take your first dose, or
when you first take an increased dose. This may mean your heart pressure is too low. It may help to lie down
until you feel better. If you are worried, or if these effects continue, talk to your doctor or pharmacist.
