1 What Lisinopril tablets are and what they are used for

Lisinopril belongs to a group of medicines called ACE inhibitors. These cause the blood vessels to relax, making it easier for the blood to pass through them.

Lisinopril tablets are used to treat:

  • high blood pressure.
  • heart failure.
  • diabetic kidney disease in patients with high blood pressure.
  • patients who are stable but have had a heart attack within the last 24 hours (short term treatment).
  • Lisinopril is recommended in children (above 6 years old) only for the treatment of high blood pressure (hypertension). Lisinopril should not be used in children with severe kidney impairment.

2 What you need to know before you take

Do not take Lisinopril tablets:

  • if you are allergic to lisinopril, other ACE inhibitors (such as captopril, ramipril) or any of the other ingredients of this medicine (listed in section 6).
  • if you have previously had allergic reactions with swollen legs, arms, face, mucous membranes and tongue with ACE inhibitors.
  • if you or any of your family have experienced allergic symptoms, which may be unrelated to the use of medicines.
  • if you are more than 3 months pregnant. (It is also better to avoid Lisinopril tablets in early pregnancy – see pregnancy section.)
  • 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 Lisinopril tablets if you:

  • are dehydrated due to sickness and diarrhoea, use of diuretics (water tablets), on a low salt diet or have severe renin-dependent hypertension.
  • have reduced blood flow to the heart (ischaemic heart disease) or disease of the blood vessels in the brain (cerebrovascular disease).
  • have any of the following heart diseases: heart failure, narrowing (stenosis) of the opening of the aortic or mitral valve or enlarged heart (hypertrophic cardiomyopathy).
  • have had a heart attack and have low blood pressure or are in cardiogenic shock.
  • have reduced kidney function, narrowing of the arteries supplying the kidneys or renovascular hypertension (high blood pressure due to a blockage in a blood vessel in the kidney).
  • are having dialysis or have had a kidney transplant.
  • are receiving treatment to lessen your reactions to bee or wasp stings or for so called LDL apheresis
  • have had surgery on your airways.
  • have problems with your immune system due to some illness or medicines such as scleroderma, lupus erythematosus, allopurinol, procainamide or drugs to suppress the immune system (especially if you also have impaired kidney function). You should tell your doctor if you have any sign of infection.
  • have diabetes.
  • are Afro-Caribbean. If you are taking Lisinopril tablets as the only treatment for your high blood pressure, you may have a reduced response to this medicine. This may mean that you may need a higher dose than usually recommended.
  • 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
  • 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 Lisinopril”

You must tell your doctor if you think you are (or might become) pregnant. Lisinopril is not recommended in early pregnancy, and must not be taken if you are more than 3 months pregnant, as they may cause serious harm to your baby if used at that stage (see pregnancy section).

Other medicines and Lisinopril

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, especially:

  • Diuretics (water tablets) - cause a large drop in blood pressure.
  • Potassium-sparing diuretics (e.g. spironolactone, triamterene or amiloride), potassium supplements, potassium salts or any other medicines that can increase levels of potassium in the blood (such as heparin and co-trimoxazole also known as trimethoprim/sulfamethoxazole). Frequent monitoring of the potassium levels in the blood is necessary.
  • Anaesthetics - the blood pressure lowering effect of Lisinopril tablets is enhanced when taken with these medicines. Therefore, it is important that the doctor/hospital is informed about your treatment with Lisinopril tablets.
  • Lithium (used to treat depression) - when taken with Lisinopril tablets an increase of lithium levels may occur. Frequent monitoring of lithium levels in blood is necessary.
  • Non-steroidal anti-inflammatory drugs (NSAIDs - pain killer and anti-inflammatory medicine) including aspirin (doses of greater than or equal to 3g a day) - may reduce the blood pressure lowering effect of Lisinopril tablets. These medicines also cause an increase in potassium levels in blood and reduce kidneys function.
  • Allopurinol (used to treat gout), medicines used to suppress the immune system or procainamide (used to treat heart rhythm disorders).
  • Tricyclic antidepressants, muscle relaxants or antipsychotics – may further reduce your blood pressure.
  • Sympathomimetics (used in asthma) - may reduce the blood pressure lowering effect of Lisinopril tablets.
  • Antidiabetics (tablets and insulin)- when taken with Lisinopril tablets blood glucose may be reduced further, particularly during the first weeks of treatment with Lisinopril tablets and in patients with reduced kidney function.
  • Other blood pressure lowering medicines e.g. fosinopril – cause an increase in the blood pressure lowering effect when taken together with Lisinopril tablets.
  • Glyceryl trinitrate, other nitrates or vasodilators e.g. hydralazine – may lower your blood pressure further.
  • Gold – may cause flushing, dizziness, blood pressure to drop too much or feeling sick.
  • 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 precautions”.

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 Lisinopril” and “Warnings and precautions”)

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 Lisinopril tablets before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine instead of Lisinopril tablets. Lisinopril tablets are not recommended in early pregnancy, and must not be taken when more than 3 months pregnant, as they 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 breast-feeding. Lisinopril tablets are not recommended for mothers who are breast-feeding, and your doctor may choose another treatment for you if you wish to breast-feed, especially if your baby is newborn, or was born prematurely.

Driving and using machines

Use of Lisinopril tablets may cause side effects such as dizziness, tiredness or confusion which may affect your ability to drive or operate machinery. Make sure you are not affected before driving or operating machinery.


Your doctor may want to carry out tests to monitor your kidney function and the amount of potassium in your blood.


You should inform your doctor that you take Lisinopril tablets if you are having an operation or an anaesthetic.

Lisinopril tablets are not recommended for use in kidney transplant patients.

If you take more than you should

If you (or someone else) swallow a lot of tablets at the same time, or you think a child may have swallowed any, contact your nearest hospital casualty department or tell your doctor immediately. Signs of an overdose include low blood pressure, disturbed circulation due to low blood pressure in blood vessels (circulatory shock), electrolyte imbalance, kidney failure, rapid breathing (hyperventilation), a racing heart beat, palpitations, a slow heart beat, dizziness, anxiety, cough.
