How Lisinopril works

It works mainly by blocking the action of an enzyme known as ACE. This enzyme stimulates the production of angiotensin II, a natural compound that causes blood vessels to narrow. Less angiotensin II present in the body means that blood vessels are more relaxed, allowing blood to flow much more freely around the body, taking the strain off the body's most important muscle – the heart.

This beneficial effect on the heart is also why this treatment is given to patients who are recovering from a heart attack.

When Lisinopril should and shouldn't be used

Lisinopril is generally a very well tolerated treatment, but like all hypertension treatments it should only be considered if a blood-pressure-lowering lifestyle has not produced results or your health is at serious risk if a treatment regimen isn't started.

People who may not be able to take this medication are those with congestive heart failure, heart disease, liver disease, kidney problems, diabetes or diseases that affect connective tissues. It will also not be prescribed to pregnant or breastfeeding women because of the known risk this treatment has to the baby.

Taking Lisinopril

It should be taken on a daily basis with a full glass of water. Food is not a requirement when taking this medication, but eating before taking it may reduce the risk of some of the minor gastrointestinal side effects. There are four doses available: 5mg, 10mg, 20mg and 40mg. The dose you should take will be decided by your doctor and adjusted according to your body's responses.

The side effects

Side effects are as much a risk with Lisinopril as they are with any prescription medication, but it doesn't mean that everybody who takes it will experience them. The most common side effects include a feeling of light-headedness, fainting, tiredness, weight gain and changes in the amount of times you need to urinate.

These side effects are likely to pass with time, as the body adjusts to the treatment, but if they persist or you find them very bothersome, you should seek immediate medical help. This should also be the procedure if you start experiencing the symptoms of an allergic reaction, which may include swelling of the face lips or tongue and breathing difficulties.
