What Dapa-Tabs is used for
Dapa-Tabs is used either alone or in combination with other medicines in the treatment of high blood pressure (hypertension).
Dapa-Tabs contains the active ingredient indapamide hemihydrate, which belongs to a group of medicine called chlorosulphamoyl diuretics (a type of fluid or water tablet)..
Why Dapa-Tabs 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.
Dapa-Tabs helps to lower blood pressure.
Ask your doctor if you have any questions about why Dapa-Tabs has been prescribed for you.
Your doctor may have prescribed Dapa-Tabs for another purpose.
Dapa-Tabs is not recommended for use in children, as its safety and effectiveness in children have not been established.
Dapa-Tabs is available only with a doctor's prescription.
There is no evidence that Dapa-Tabs is addictive.
