Quinapril belongs to a group of medicines called angiotensin
converting enzyme (ACE) inhibitors, which make the blood
vessels become wider, reducing the pressure in the vessels. This
makes blood flow more easily and reduces the effort needed for
the heart to pump blood around the body.
Quinapril can be used to:
• lower your blood pressure if it is too high (a condition
called hypertension)
• help your heart pump blood around your body if you have a
condition known as congestive heart failure (along with
other medicines).
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). Symptoms of an allergic
reaction include itching, a rash on the skin or difficulty breathing
• if you have taken an ACE inhibitor before and had an allergic
reaction to it resulting in swelling of the face, lips, tongue and/
or throat with difficulty swallowing or breathing, or you or any
member of your family have suffered a similar allergic reaction
for any reason in the past (angioedema)
• if you suffer from a severe allergic skin reaction called hereditary/
idiopathic angioneurotic oedema, where itchy swellings erupt
on the face, hands and/or genitals and in the mouth
• if you are more than 3 months pregnant (it is also better to
avoid Quinapril in early pregnancy – see pregnancy section)
• if you have a condition causing obstruction to blood flow from
the heart like heart valve disease.
• 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 suffer from a heart problem (other than the one being
treated) or narrowing of the main artery carrying blood out of
the heart (aortic stenosis)
• you have liver problems
• you suffer from kidney problems, narrowing of the blood
vessels to the kidney (renal artery stenosis), have had a kidney
transplant or need haemodialysis treatment
• you suffer from a collagen vascular disease (deposits of collagen
in your blood vessels) e.g. lupus erythematosus or scleroderma
• you are dehydrated (dry) due to treatment with diuretics
(‘water tablets’), dialysis, a low salt diet, vomiting or diarrhoea.
You may be more likely to suffer from a very large drop in your
blood pressure (hypotension) when you start taking the tablets
and may feel faint or light-headed
• you have excessive production of aldosterone causing high
blood pressure also called primary hyperaldosteronism
• you have a history of allergy or asthma
• you are diabetic, as the dose of anti-diabetic medicine may
need adjusting
• you are having treatment to remove cholesterol from your
blood by machine also called low density lipoprotein apheresis
• you are having or about to have treatment to reduce the
effects of an allergy to a bee or wasp sting also called
desensitisation treatment
• 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 pregnancy section)
• you are going to have an operation or need an anaesthetic
• 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.
- aliskiren.
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 should be aware that this medicine may be less effective
at lowering the blood pressure in black patients than in nonblack patients.
Other medicines and Quinapril
Tell your doctor or pharmacist if you are taking, have recently
taken or might take any other medicines, including medicines
obtained without a prescription, or the following:
• other medicines to lower blood pressure e.g. methyldopa, atenolol
• other diuretics e.g. triamterene, amiloride, furosemide,
• potassium supplements (or salt substitutes containing potassium)

• procainamide, to treat abnormal heart rhythms
• lithium, to treat mental illness
• other medicines that interact with magnesium salts e.g. the
antibiotic tetracycline
• antidiabetic medicines such as insulin, gliclazide, metformin;
doses may need to be adjusted
• painkillers called non-steroidal anti-inflammatory drugs
(NSAIDs) e.g. ibuprofen and aspirin
• allopurinol, often used to treat gout
• medicine to treat cancer
• immunosuppressive agents e.g. ciclosporin, used after
transplant surgery or for autoimmune disorders such as
rheumatoid arthritis
• corticosteroids e.g. prednisolone
• antacids, to relieve indigestion and heartburn
• medicines that act on your nervous system e.g. barbiturates,
alcohol and narcotics
• medicines used to treat stiffness and inflammation of your
muscles, bones and joints including gold therapy such as
sodium aurothiomalate, which can lead to flushing of your
face, feeling sick (nausea), being sick (vomiting) and low
blood pressure.
Your doctor may need to change your dose and/or to take
other precautions:
• if you are taking an angiotensin II receptor blocker (ARB) or
aliskiren (see also information under the headings “Do not take
Quinapril” and “Warnings and precautions”).
Quinapril with food, drink and alcohol
Quinapril can be taken with or without food. Drinking alcohol
while being treated with this medicine may make you dizzy
or sleepy.
Pregnancy and breast-feeding
You must tell your doctor if you think you are (or might become)
pregnant. Your doctor will normally advise you to stop taking
Quinapril before you become pregnant or as soon as you know
you are pregnant and will advise you to take another medicine
instead of Quinapril. Quinapril is not recommended in early
pregnancy, and must not be taken when more than 3 months
pregnant, as it may cause serious harm to your baby if used after
the third month of pregnancy.
Tell your doctor if you are breast-feeding or about to start breastfeeding. Breast-feeding newborn babies (first few weeks after
birth), and especially premature babies, is not recommended
whilst taking Quinapril.
In the case of an older baby your doctor should advise you on
the benefits and risks of taking Quinapril whilst breast-feeding,
compared with other treatments.
Ask your doctor or pharmacist for advice before taking
any medicine.
Driving and using machines
This medicine may affect your ability to drive a car or operate
machinery. However, do not perform these tasks if you suffer
from side effects such as dizziness or feeling tired. These effects
can sometimes occur at the start of treatment, and may become
worse if you drink alcohol at the same time.
Quinapril contains lactose monohydrate
This medicine contains lactose, a type of sugar. If you have been
told by your doctor that you have an intolerance to some sugars,
such as lactose, contact your doctor before taking this
medicinal product.
Always take this medicine exactly as your doctor or pharmacist
has told you. Check with your doctor or pharmacist if you are
not sure.
To treat high blood pressure
The recommended starting dose is 10 mg once a day. If you
are already taking a diuretic (‘water’ tablet) the starting dose is
2.5 mg a day.
After 3 to 4 weeks, your doctor may increase this to a dose that
best controls your blood pressure. The usual daily dose needed
is between 20 mg and 40 mg, taken as a single dose or divided
into two doses. A few patients have been treated with doses up
to 80 mg a day.
To treat heart failure
You will also be taking other medicine for your condition, such
as a diuretic (‘water’ tablet) or digoxin.
The recommended starting dose is 2.5 mg in the morning. Every
2 to 3 weeks your doctor may increase this to a dose of between
10 mg and 40 mg a day. Most patients will only need 10-20 mg
per day, when given with water tablets or digoxin. This may be
taken as a single dose or divided into two doses. The maximum
daily dose is 40 mg and this dose should not be exceeded. At
the start of treatment your doctor will monitor your condition
closely. In some cases your doctor may wish to take the
precaution of placing you in hospital just for the start of therapy.
Use in the elderly or people with kidney problems
If you are elderly or have kidney problems, you may be more
sensitive to the effects of Quinapril. The usual starting dose for
treating high blood pressure is 2.5 mg. Your doctor will slowly
increase the dose until your condition is under control.
Use in children and adolescents
Quinapril tablets are not recommended for children and
adolescents under 18 years of age.
Method of administration
• Try to take the tablets at the same time every day.
• Swallow the tablets with a glass of water.
• Do not chew or crush the tablets.
• The score lines on the 10 mg and 20 mg tablets are not
intended for breaking the tablet.
If you take more Quinapril than you should
Contact your doctor or nearest hospital emergency department
immediately. Take the container and any remaining tablets with
you. Symptoms of overdose include severe low blood pressure,
shock, feeling disorientated, a slow heart rate and kidney failure.



If you forget to take Quinapril
Miss out the forgotten dose completely and take the next dose
at the normal time. Do not take a double dose to make up for a
forgotten dose.
If you stop taking Quinapril
Do not stop taking Quinapril without talking to your doctor first.
It is important to keep taking your tablets. They help to control
your blood pressure. Do not wait until your tablets are finished
before seeing your doctor.
If you have any further questions on the use of this medicine, ask
your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although
not everybody gets them.
If any of the following happen, stop taking Quinapril and
tell your doctor immediately or go to your nearest hospital
emergency department:
Uncommon: may affect up to 1 in 100 people:
• allergic reactions causing swelling of the face, lips, tongue and/
or throat which may cause difficulty breathing or swallowing.
Swelling is more likely to occur in black patients (angioedema)
severe chest pain which may spread to the neck and shoulders
(symptoms of a heart attack or angina)
• tightness of the chest, shortness of breath, wheezing or trouble
breathing, irregular or strong heartbeat (palpitations).
Rare: may affect up to 1 in 1,000 people:
• skin rash, which may blister, and looks like small targets (central
dark spots surrounded by a paler area, with dark ring around
the edge) (erythema multiforme)
• blistering of the skin and surrounding surfaces (pemphigus).
Very rare: may affect up to 1 in 10,000 people:
• severe abdominal pain causing you to be sick
(intestinal angioedema).
Not known: frequency cannot be estimated from the
available data:
• sudden signs of allergy such as rash, itching or hives on the
skin, swelling of the face, lips, tongue or other parts of the body,
shortness of breath, wheezing or trouble breathing (anaphylaxis)
• severe headache, eyesight changes, numbness or weakness,
and difficulty speaking (symptoms of a stroke)
• severe abdominal and back pain accompanied by feeling very
unwell (pancreatitis)
• skin condition with severe blisters and bleeding in the lips,
eyes, mouth, nose and genitals (Stevens- Johnson syndrome)

large blisters and ends with peeling of layers of skin. This is
accompanied by fever and chills, aching muscles and generally
feeling unwell (toxic epidermal necrolysis)
• feel unusually tired, look pale, notice unusual bleeding, bruise
easily, or suffer from frequent nosebleeds, sore throats or fever
(these may occur due to a decrease in the number of blood
cells, known as neutropenia and agranulocytosis)

pale stools.
These are serious side effects. You may need medical attention.
It is very important that you stop taking Quinapril
immediately and see your doctor if you feel dizzy, lightheaded or faint (especially at the start of treatment or when
the dose has increased or when you stand up). These side
effects are caused by a large drop in your blood pressure
and could lead to a heart attack (severe chest pain) or
stroke. This is more likely to occur if you have been taking
diuretics (water tablets), other blood pressure medication in
addition to Quinapril or if you are dehydrated or on dialysis.
