Chlorthalidone
About Chlorthalidone
Chlorthalidone is used to treat high blood pressure, heart failure and oedema (a build-up of fluid in the body). Hypertension or high blood pressure is a chronic condition in which the force exerted by the blood against the artery wall is high. Higher blood pressure leads to heart disease, irregular heartbeat and other complications like oedema (fluids of the body get trapped in the tissues of the hands, arms, feet, ankles and legs, leading to swelling).
Chlorthalidone contains Chlortalodone, which works by increasing the amount of urine that is passed out from the kidneys. Thereby it helps treat hypertension and oedema.
Take Chlorthalidone as prescribed by your doctor. In some cases, you may experience headaches, nausea or dizziness, which usually resolve over time. However, if the side effects are persistent, reach out to your doctor.
Do not stop taking this medicine without completing the prescribed dose, as abrupt stopping it may cause a rise in blood pressure and can increase the risk of getting heart disease and stroke. Inform your doctor if you are suffering from any kidney, liver, or heart disease. Inform your doctor if you are pregnant or breastfeeding before taking Chlorthalidone. Also, tell your doctor if you are taking any other medicines or are allergic to this medicine.
Uses of Chlorthalidone
Medicinal Benefits
When you take Chlorthalidone, the blood vessels in your body will be relaxed, which will help lower the raised blood pressure. Also, it widens the blood vessels (lining of arteries wall) and helps to improve the blood flow. It helps in losing excess fluids from the body by increasing the production of urine. This reduces the workload on the heart and makes the heart more efficient at pumping blood throughout the body. Thus, it helps to lower high blood pressure, reducing the chances of heart attack or stroke. Chlorthalidone also helps decrease fluid buildup, which reduces inflammation or swelling. In addition, this relieves oedema and helps you carry out your daily activities more efficiently.

Disease/Condition Glossary
Hypertension: It is a chronic condition when blood pressure is too high. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Blood pressure is the measurement of the force our heart uses to pump blood to all body parts. Raised blood pressure can cause chest pain (angina) and heart attack (when the blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. High blood pressure can be diagnosed with the help of a blood pressure monitor or sphygmomanometer. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is the pressure when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg and diastolic pressure is 90 mm of Hg. Ideal blood pressure should be between 90/60 mm of Hg and 120/80 mm of Hg.
Oedema: Also known as 'dropsy' or 'hydropsy', is a condition of fluid retention in the body characterized by swelling of the body's tissue, including ankles, feet and legs. It is usually caused by standing or sitting in the same position for too long, eating too much salty food, and being overweight. Oedema mainly affects the lymphatic system (including the circulatory and immune system) and organs like the tonsils, spleen, and thymus, which maintain fluid balance and fight infections.
FAQs
Chlorthalidone is used to treat high blood pressure (hypertension) and oedema (a build-up of fluid in the body).
Chlorthalidone works by increasing the amount of urine passed out from the kidneys. It effectively reduces excess fluid levels in the body and treats oedema (swelling) associated with heart, liver, kidney, or lung disease. This, in turn, reduces the workload on the heart and makes the heart more efficient at pumping blood throughout the body. So, it helps to lower high blood pressure, reducing the chances of heart attack or stroke.
