Why it’s used
Indapamide is used to lower blood pressure in people with high blood pressure. It will help control your high blood pressure but it won’t cure it. When taken long term, it may prevent you from having a heart attack or stroke.
Indapamide is also used to treat edema (salt and fluid retention) in people with congestive heart failure. It will help control your swelling or fluid retention, but it won’t cure it. When taken long-term, it may keep your heart failure from getting worse.
How it works
Indapamide belongs to a class of drugs called diuretics (water pills). A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.
Indapamide makes your body get rid of extra water and salt through your urine. This results in less swelling and lowered blood pressure.
Indapamide oral tablet may cause drowsiness. It may also cause other symptoms.
