Hydrochlorothiazide

Hydrochlorothiazide is a medication that's commonly used to treat high blood pressure (hypertension) and fluid retention (edema) caused by various conditions, such as heart failure, liver disease, or kidney disorders. It belongs to a class of drugs known as thiazide diuretics, or "water pills," which help your body get rid of excess salt and water by increasing the amount of urine you produce.

By reducing the amount of fluid in your blood vessels, hydrochlorothiazide helps lower blood pressure and decrease swelling. It's often prescribed in combination with other medications for better blood pressure control.

As with any medication, there can be side effects, including dizziness, headache, dehydration, and an imbalance of electrolytes like potassium and sodium. It's important to follow your healthcare provider's instructions when taking hydrochlorothiazide and to have regular check-ups to monitor your condition and any potential side effects.
