What this medicine is used for
The name of your medicine is GenRx Indapamide. It contains the active ingredient, indapamide hemihydrate.
It is used either alone or with other medicines to treat:

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.
How it works
Indapamide, at a dose of 2.5 mg, 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. It is not fully understood how it exactly does this.
Indapamide can be used alone or in combination with other medicines to lower blood pressure.
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 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.
There are usually no symptoms of high blood pressure. The only way of knowing that you have it is to have your blood pressure checked on a regular basis.
There is no known evidence to show that this medicine is addictive.
Use in children
There is not enough information to recommend the use of this medicine in children.

This is especially important for patients, who are at high risk of developing electrolyte disturbances (such as elderly, patients who are taking many medicines or patients who are malnourished).

Also make sure you tell your doctor if you become sick and have severe or continuing vomiting or diarrhoea while taking indapamide. The loss of additional water and certain salts such as potassium from the body may make you feel faint, lightheaded, weak or sick.
Indapamide may increase the sensitivity of your skin to sunlight.
