How it works
Indapamide is thought to lower blood pressure by relaxing some of the blood vessels
in the body. The blood vessels can then carry the same volume of blood more easily.
Everyone has blood pressure. This pressure helps to move your 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 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.
Ask your doctor if you have any questions about why indapamide SR has been prescribed
Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
This medicine is not addictive.
