Hydrochlorothiazide
Summary
Hydrochlorothiazide is used to treat high blood pressure, which is hypertension, and fluid retention, which is edema. It helps lower blood pressure by removing excess salt and water from your body, reducing the amount of fluid in your blood vessels. This medication can also manage swelling caused by conditions like heart failure and kidney disorders.
Hydrochlorothiazide is a diuretic, which means it helps your body remove excess salt and water. It works by making your kidneys filter out more salt and water, which lowers blood pressure and reduces swelling. Think of it like a sponge soaking up extra water in your body, decreasing fluid in your blood vessels.
The usual starting dose of Hydrochlorothiazide for adults is 25 mg once daily. Your doctor may adjust the dose based on your response and needs. The maximum recommended dose is 50 mg per day. For children or the elderly, dose adjustments may be necessary, and careful monitoring is required. Always follow your doctor's specific dosing instructions.
Common side effects of Hydrochlorothiazide include dizziness, which is a feeling of lightheadedness, and increased urination, which means you may need to go to the bathroom more often. These effects are usually mild and may go away as your body adjusts to the medication. If you notice new symptoms, talk with your doctor.
Hydrochlorothiazide can cause dehydration, which means your body doesn't have enough fluids, leading to low blood pressure or kidney problems. It may also cause electrolyte imbalances, which are changes in the levels of minerals in your blood. Avoid this medication if you have severe kidney problems or an inability to urinate.
