What is Chlorthalidone?

Chlorthalidone is a medication that belongs to a class of drugs called thiazide diuretics. It is usually prescribed to help lower high blood pressure and treat edema (swelling) caused by various medical conditions.

Chlorthalidone works by increasing the excretion of water and sodium from the body, which helps to decrease the amount of fluid in the blood vessels. This, in turn, reduces blood pressure and the workload on the heart.

Chlorthalidone is available in tablet form and is taken orally. The typical dose is 25 mg, though this may be adjusted based on individual patient needs and the condition being treated. It is important to take Chlorthalidone exactly as prescribed and to follow any other instructions provided by a healthcare professional.

While Chlorthalidone is generally considered safe and effective, it can cause side effects in some people. These may include dizziness, headache, muscle weakness, and increased urination. In rare cases, Chlorthalidone can cause more serious side effects such as allergic reactions, pancreatitis, and electrolyte imbalances. If any side effects are experienced, it is important to contact a healthcare professional immediately.

Dosing and Administration
