The first dose of fosinopril can make you feel dizzy. It is best taken at bedtime.
Fosinopril is generally well tolerated but if you develop a troublesome cough, you should let your doctor know.
Some painkillers and indigestion remedies interfere with fosinopril. Ask your pharmacist for advice before you buy any medicines 'over the counter'.
En un coup d'œil
Fosinopril is a medicine used to treat high blood pressure and heart failure.
It belongs to a group of medicines called ACE inhibitors.
You usually take it once a day, with or without food.
Your doctor will advise you on the correct dosage.
Common side-effects include a dry cough and dizziness.
See a doctor immediately if you have swelling of your face, mouth, tongue or throat.
About fosinopril
Type de médicament | An angiotensin-converting enzyme (ACE) inhibitor |
Utilisé pour | High blood pressure; heart failure |
Aussi appelé | Fosinopril sodium |
Disponible sous forme de | Comprimés |
Fosinopril belongs to a class of medicines called Inhibiteurs de l'enzyme de conversion de l'angiotensine (ECA). You may have been prescribed it to reduce high blood pressure (hypertension), or to treat une insuffisance cardiaque. Heart failure is a condition where your heart does not work as well as it should.
ACE inhibitors like fosinopril prevent your body from creating a hormone known as angiotensin II. They do this by blocking (inhibiting) a chemical called angiotensin-converting enzyme. This widens your blood vessels and helps to reduce the amount of water put back into your blood by your kidneys. These actions help to decrease blood pressure. Although people with high blood pressure often do not feel unwell, if left untreated, high blood pressure can harm the heart and damage blood vessels, leading to a heart attack or stroke.
In heart failure, there can be too much circulating fluid in your blood vessels because your heart is not working as efficiently as it once did. Fosinopril helps to reduce this. It also appears to have a protective effect on the heart and slows the progression of the heart failure.
Before taking fosinopril
Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking fosinopril it is important that your doctor knows:
Si vous êtes enceinte ou si vous allaitez.
Si vous avez des problèmes avec le fonctionnement de vos reins, ou des problèmes avec le fonctionnement de votre foie.
If you are lacking in fluid in the body (dehydrated) - for example, if you have had diarrhoea or sickness very recently.
If you have been told you have a build-up of fatty deposits on the walls of your arteries, a condition called atherosclerosis.
If you have a particular type of poor circulation called peripheral arterial disease.
If you have collagen vascular disease, this includes conditions such as systemic lupus erythematosus (SLE) and scleroderma.
If you have been told you have heart muscle disease (cardiomyopathy), or narrowing of the main blood vessel from your heart (aortic stenosis).
If you have ever had a reaction where your face, tongue or throat swells (angio-oedema).
If you are having desensitisation treatment to protect against bee and wasp stings.
If you are having dialysis treatment, or treatment to remove cholesterol from your blood by a machine (LDL apheresis).
Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et les médecines complémentaires.
If you have ever had an allergic or unusual reaction to any other ACE inhibitor (such as captopril, ramipril or perindopril), or to any other medicine.
How to take fosinopril
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about fosinopril and will provide you with a full list of side-effects which you could experience from taking it.
Take the tablets exactly as your doctor tells you to. Fosinopril is taken once a day. If you have high blood pressure, your doctor will advise you take your very first dose at bedtime. This is because you can feel quite dizzy when you first start taking it. After the first dose, you can generally take fosinopril at a time of day you find easy to remember. For most people this will be in the morning.
Try to take your doses at the same time of day each day as this will help you to remember to take your doses regularly. You can take fosinopril tablets either with or without food. It is best to swallow the tablet with a drink of water.
There are two strengths of fosinopril tablets - 10 mg and 20 mg. It is usual to start by taking the 10 mg strength tablets, although your doctor may increase your dose over the first few weeks. This allows your doctor to make sure that you have the dose that helps your condition and helps to avoid any unwanted side-effects, such as dizziness. Each time you collect a new supply, check to make sure the tablets are the strength that you are expecting.
Si vous oubliez de prendre une dose, prenez-la dès que vous vous en souvenez. Si vous ne vous en souvenez que le lendemain, laissez de côté la dose oubliée de la veille et prenez la dose prévue normalement. Ne prenez pas deux doses en même temps pour compenser une dose oubliée.
Tirer le meilleur parti de votre traitement
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 from time to time to check that your kidneys are working well.
It is very important that you follow any dietary and lifestyle advice that you have been given by your doctor. This can include advice about 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 fosinopril. This is because some medicines (such as anti-inflammatory painkillers and indigestion remedies) can interfere with your treatment.
It is likely that your doctor will advise that you do not to use salt substitutes while you are taking fosinopril. These products have a high content of potassium which could be harmful for you.
If you drink alcohol, ask your doctor for advice about drinking alcohol while you are on fosinopril. Alcoholic drinks can make you feel light-headed or dizzy, and they may not be advisable for you.
If you have diabetes you may need to check your blood sugar (glucose) more frequently, as the tablets can 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 fosinopril. This is because some anaesthetics could cause your blood pressure to drop too low.
Treatment with fosinopril is often long-term unless you experience an adverse effect. Continue to take the tablets unless you are advised otherwise.
Can fosinopril cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the more common ones associated with fosinopril. The best place to find a full list of the side-effects which can be associated with your medicine, is from the manufacturer's printed information leaflet supplied with the medicine. Alternatively, you can find an example of a manufacturer's information leaflet in the reference section below. Speak with your doctor or pharmacist if any of the following continue or become troublesome.
Commun fosinopril side-effects (these affect fewer than 1 in 10 people) | Que puis-je faire si je ressens cela ? |
Dry irritating cough | If this continues, speak with your doctor, as a different type of medicine may be more suitable for you |
Se sentir étourdi ou faible | 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. Do not drive and do not use tools or machines while you feel dizzy |
Feeling sick (nausea) or being sick (vomiting), tummy (abdominal) pain, diarrhoea, indigestion | Stick to simple foods - avoid fatty or spicy meals |
Headache, muscle aches and pains, chest pain, cold and flu-like symptoms, sore throat | Ask your pharmacist to recommend a suitable remedy |
Blurred eyesight | Ne conduisez pas et n'utilisez pas d'outils ou de machines lorsque vous êtes affecté |
Tingling feelings, feeling tired, fast heartbeat, skin rash, mood changes, sleeping problems, sexual problems, difficulties passing urine | Si l'un de ces éléments devient problématique, parlez-en à votre médecin |
Important: if you experience any of the following potentially serious symptoms, stop taking fosinopril 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 the whites of your eyes. These may be signs of a liver problem called jaundice, which is a rare side-effect.
Si vous ressentez d'autres symptômes que vous pensez être dus aux comprimés, parlez-en à votre médecin ou à votre pharmacien pour obtenir des conseils supplémentaires.

Questions fréquemment posées
Can I stop taking fosinopril once my blood pressure improves or my heart failure symptoms get better?
Treatment with fosinopril is often for the long-term, unless you experience a side effect that requires you to stop. It's important to continue taking the tablets as prescribed by your doctor, even if you feel better. Always consult your doctor before making any changes to your medication.
What should I do if I typically take fosinopril in the mornings but forget a dose?
If you forget to take a dose, take it as soon as you remember. However, if you don't remember until the following day, you should skip the forgotten dose from the previous day and take only the dose that is due as normal. Do not take two doses at the same time to compensate for a missed dose.
Are there any specific situations where I need to inform medical staff that I am taking fosinopril?
Yes, if you are planning to have an operation or dental treatment, it is important to tell the person carrying out the treatment that you are taking fosinopril. This is because some anaesthetics could cause your blood pressure to drop too low when combined with the medication.
What should I do if I notice yellowing of my skin or eyes while taking fosinopril?
If you experience any yellowing of your skin or the whites of your eyes, you should stop taking fosinopril immediately and contact your doctor for advice straight away. These can be signs of a rare but serious liver problem called jaundice.
Why do I need blood tests periodically while taking fosinopril?
Your doctor will want you to have blood tests from time to time to monitor your progress and check that your kidneys are working well. This is an important part of ensuring the treatment remains safe and effective for you.
