Quinapril is generally well tolerated but if you develop a troublesome cough, let your doctor know.
The first dose may make you feel dizzy.
Some painkillers and indigestion remedies interfere with quinapril , so ask your pharmacist for advice before you buy any medicines.
|Type of medicine ||Angiotensin-converting enzyme (ACE) inhibitor |
|Used for ||High blood pressure (hypertension) |
|Also called ||Accupro®; Quinil®; Accuretic® (quinapril with hydrochlorothiazide) |
|Available as ||Tablets |
Quinapril is used to treat hypertension (high blood pressure) and heart failure (a condition where your heart does not work as well as it should).
ACE inhibitors like quinapril prevent your body from creating a hormone known as angiotensin II. They do this by blocking (inhibiting) a chemical called angiotensin-converting enzyme. This relaxes your blood vessels and helps to reduce the amount of water put back into your blood by the kidneys. These actions help to decrease blood pressure. People with high blood pressure often do not feel unwell but, if left untreated, high blood pressure can harm the heart and damage blood vessels, leading to a heart attack or stroke. Quinapril can be used on its own or alongside other medicines which reduce blood pressure (such as hydrochlorothiazide).
In heart failure, there may be too much circulating fluid in your blood vessels. ACE inhibitors help to reduce this. They appear to have a protective effect on the heart and slow the progression of the heart failure.
Before taking quinapril
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking quinapril it is important that your doctor or pharmacist knows:
- If you are pregnant, trying for a baby or breast-feeding.
- If you have liver or kidney problems.
- If you are dehydrated - for example, if you have had diarrhoea or sickness very recently.
- If you have been told you have atherosclerosis (a build-up of fatty deposits on the walls of your arteries).
- If you have peripheral vascular disease (a particular type of poor circulation).
- If you have collagen vascular disease, such as systemic lupus erythematosus (SLE) or scleroderma.
- If you have been told you have cardiomyopathy (cardiac muscle disease), or aortic stenosis (narrowing of the main blood vessel from your heart).
- If you have ever had angio-oedema (where your face, tongue or throat swells).
- If you are having desensitisation treatment to protect against bee and wasp stings.
- If you have dialysis treatment, or treatment to remove cholesterol from your blood by a machine (LDL apheresis).
- If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
- If you have ever had an allergic or unusual reaction to any other ACE inhibitor (such as ramipril, captopril and perindopril), or to any other medicine.
How to take quinapril
- Before you start this treatment, read the manufacturer's printed information leaflet from inside the pack. The leaflet will give you more information about the specific brand of quinapril you have been given, and a full list of possible side-effects from taking it.
- Take the tablets exactly as your doctor has told you to. Your dose will be on the label of the pack to remind you. It is usually taken once daily, but it may be prescribed as a twice-daily dose. Your doctor may advise you take your very first dose at bedtime. This is because you may feel dizzy when you first start taking it.
- After this first dose, take quinapril at a time of day you find easy to remember and try to take it at the same time each day. This will help you to remember to take it. You can take quinapril tablets before or after meals. Swallow the tablets whole with a drink of water.
- If you forget to take a dose, take it as soon as you remember. If when you remember it is almost time to take your next dose, skip the missed dose and take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
- Try to keep your regular appointments with your doctor. This is so your progress can be monitored. Your doctor will want you to have some blood tests to check on your kidney function from time to time.
- It is very important that you follow any dietary and lifestyle advice that you may have been given by your doctor, such as eating a healthy diet, not smoking, and taking regular exercise.
- If you buy any medicines, check with a pharmacist that they are suitable to take with quinapril. This is because some medicines (such as anti-inflammatory painkillers and indigestion remedies) may interfere with these tablets.
- If you drink alcohol, ask your doctor for advice about taking quinapril and alcohol. Alcohol will increase feelings of light-headedness and may not be recommended for you.
- If you have diabetes you may need to check your blood glucose more frequently, as these tablets may lower the levels of sugar in your blood. Your doctor will advise you about this.
- If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking quinapril. This is because if you need an anaesthetic, it may make your blood pressure drop.
- Treatment with quinapril is usually long-term unless you experience an adverse effect. Continue to take the tablets unless you are advised otherwise.
Can quinapril cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. These usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.
|Common quinapril side-effects - these affect less than 1 in 10 people who take this medicine ||What can I do if I experience this? |
|Feeling light-headed or dizzy, especially when standing up ||Getting up more slowly should help. If you begin to feel |
dizzy, lie down so that you do not faint, then sit for a few moments before standing. If this continues beyond the first few days, speak with your doctor
|Dry irritating cough ||If this continues, speak with your doctor, as an alternative medicine may be better for you |
|Headache ||Ask your pharmacist to recommend a suitable painkiller |
|Feeling or being sick, indigestion, abdominal pain, diarrhoea ||Stick to bland foods - avoid rich and spicy meals |
|Throat infections, runny nose, tingling feelings in your hands or toes, problems sleeping ||Speak with your doctor if any of these become troublesome |
Important: if you experience any of the following rare but serious symptoms, stop taking quinapril and contact your doctor for advice straightaway:
- Any difficulty breathing, or swelling of your face, mouth, tongue or throat. These are signs of an allergic reaction.
- Any yellowing of your skin or whites of your eyes. These may be signs of jaundice which is a rare side-effect.
- A severe skin rash.
If you experience any other symptoms which you think may be due to this medicine, speak with your doctor or pharmacist.
