Type of medicine ACE (angiotensin-converting enzyme) inhibitor
Used for High blood pressure
Heart failure
Also called Fosinopril sodium
Available as Tablets

Fosinopril is in a class of drugs called angiotensin-converting enzyme (ACE) inhibitors.

Angiotensin-converting enzyme (ACE) is an enzyme in the body that is necessary in the formation of a chemical called angiotensin II. Angiotensin II causes the narrowing of arteries, thereby increasing blood pressure. ACE inhibitors prevent the formation of angiotensin II, hence widening the blood vessels and helping lower the blood pressure.

Fosinopril can be used on its own or alongside other medicines to help lower the blood pressure and treat heart failure (a condition where the pumping action of the heart is reduced).

Before taking fosinopril make sure your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you suffer from kidney or liver problems.
  • If you are on a salt restricted diet or use salt substitutes which contain potassium.
  • If you have dialysis treatment.
  • If you are dehydrated (for example if you have had diarrhoea and sickness very recently).
  • If you have atherosclerosis (the build-up of fatty deposits on the walls of arteries).
  • If you suffer from peripheral vascular disease (a particular type of poor circulation).
  • If you suffer from a collagen vascular disease, such as systemic lupus erythematosus (SLE) or scleroderma.
  • If you have cardiomyopathy (cardiac muscle disease) or aortic stenosis (narrowing of the blood vessel from the heart).
  • If you have a history of angioedema (where the face, tongue and throat swell).
  • If you are taking other medicines, including those available to buy without a prescription, herbal or complementary medicines.
  • If you have ever had an allergic or unusual reaction to any other ACE inhibitor (this includes ramipril, lisinopril and perindopril) or to any other medicine.
  • Before beginning treatment, read the manufacturer's printed information leaflet.
  • Take your medication exactly as directed by your doctor.
  • It is not important whether you take your dose before or after food.
  • Fosinopril is usually taken once a day. Try to take fosinopril at the same time each day to avoid missing any doses.
  • If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a missed dose.
  • If you are having any treatment like an operation or dental treatment, tell the person carrying out the treatment which medicines you are taking.
  • Keep your regular doctor's appointment so your progress can be monitored.
  • Do not take indigestion remedies at the same time as fosinopril. If you need to take an indigestion remedy, leave at least two hours before or after your dose of fosinopril.
  • Treatment with fosinopril is usually life-long.
  • Fosinopril may cause dizziness or lightheadedness, especially the first time you take it. Make sure you know how you react to this medicine before you drive, operate machinery or do other jobs that could be dangerous if you were not fully alert.
  • If you buy any medicines, check with a pharmacist that they are safe to take with fosinopril.
