Indapamide is a generic drug that belongs to the class of thiazide-like diuretics, or water pills. It is used to treat high blood pressure (hypertension) and fluid retention (edema) in people with congestive heart failure. It works by making the kidneys excrete more water and salt, which lowers the blood volume and pressure. Indapamide can also reduce the risk of heart attack and stroke in people with hypertension.
How to use indapamide
Indapamide comes as an oral tablet that is usually taken once a day in the morning. The dosage depends on the condition being treated and the response to the medication. The usual dose range is 1.25 mg to 5 mg per day. Indapamide can be taken with or without food, but it should be taken at the same time each day. It is important to drink plenty of fluids while taking indapamide, unless your doctor tells you otherwise.
Indapamide may cause increased urination during the first few weeks of treatment, so it is best to avoid taking it at bedtime. You should also avoid alcohol and caffeine, which can increase the diuretic effect and cause dehydration. You should not stop taking indapamide without consulting your doctor, as this may cause your blood pressure to rise suddenly.
