What RENITEC PLUS 20/6 is used for
RENITEC PLUS 20/6 lowers high blood pressure, which doctors call hypertension.
Everyone has blood pressure. This pressure helps get your 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. RENITEC PLUS 20/6 helps to lower your blood pressure.
RENITEC PLUS 20/6 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
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.
Your doctor may have prescribed RENITEC PLUS 20/6 for another reason. Ask your doctor
