What Enalapril/HCT Sandoz 20mg/6mg is used for
The name of your medicine is Enalapril/HCT Sandoz 20mg/6mg. It contains the active
ingredients enalapril maleate and hydrochlorothiazide.
It is used to treat mild to moderate high blood pressure (hypertension).
Everyone has blood pressure. This pressure helps to circulate the blood all around
your body. Your blood pressure may be different at different times of the day, depending
on how busy or worried you are. You have hypertension (high blood pressure) when your
blood pressure stays higher than is needed, even when you are calm and relaxed.
There are usually no symptoms of hypertension. The only way of knowing that you have
hypertension is to have your blood pressure checked on a regular basis. If high blood
pressure is not treated it can lead to serious health problems. You may feel fine
and have no symptoms, but eventually hypertension can cause stroke, heart disease
and kidney failure. Enalapril/HCT Sandoz 20mg/6mg helps to lower your blood pressure.
Ask your doctor if you have any questions about why this medicine has been prescribed
Your doctor may have prescribed it for another reason.
How Enalapril/HCT Sandoz 20mg/6mg works
Enalapril/HCT Sandoz 20mg/6mg contains two active ingredients. One of these is enalapril
maleate. It belongs to a group of medicines called angiotensin converting enzyme (ACE)
inhibitors. It works by widening your blood vessels. This means that blood is able
to pass through them more easily and the heart doesn't have to pump as hard to move
blood around the body.
The other active ingredient is hydrochlorothiazide, which is a fluid tablet or diuretic.
It helps reduce the amount of fluid in the body by making your kidneys pass more water
Both of these active ingredients help to lower high blood pressure.
There is no evidence that Enalapril/HCT Sandoz 20mg/6mg is addictive.
