Frequently Asked Questions
It is primarily used to treat high blood pressure (hypertension) and edema (fluid retention) associated with heart, liver, or kidney conditions.
No, it is the generic, international nonproprietary name (INN) for the drug. It is sold under various brand names (e.g., Microzide in the US) and is a common component in combination pills (e.g., losartan/hydrochlorothiazide).
It works by preventing the kidneys from reabsorbing too much salt and water. This increases urine output, reduces blood volume, and relaxes blood vessels, which lowers blood pressure.
In informal conversation with a doctor, 'water pill' might be understood, but it is imprecise as it refers to diuretics in general. For accuracy, especially when discussing specific dosages or side effects, using the full name 'hydrochlorothiazide' or the abbreviation 'HCTZ' is best.
