Why IDAPREX COMBI 4/1.25 is used for high blood pressure

Everyone has blood pressure. This pressure helps to circulate blood all around the body. Your blood pressure may be different at different times of the day, depending on how busy or stressed you are. You have high blood pressure (also known as hypertension) when your blood pressure stays higher than is needed, even when you are calm and relaxed.
If high blood pressure is not treated it can lead to serious health problems. You may feel fine and have no symptoms, but eventually it can cause stroke, heart disease and kidney failure.
IDAPREX COMBI 4/1.25 helps to lower your blood pressure.
Ask your doctor if you have any questions about why IDAPREX COMBI 4/1.25 has been prescribed for you.
