Table of contents:

Hygroton is a prescription medication used to treat high blood pressure (hypertension) and fluid retention. It contains chlorthalidone. Chlorthalidone is classified as a diuretic or "water pill" and works by increasing the amount of urine produced by the body, especially when the medication is first started.

By lowering the level of blood pressure, chlorthalidone can help to prevent strokes, heart attacks, and kidney problems. Additionally, it is used to reduce excess salt and water in the body caused by conditions such as heart failure, liver disease, and kidney disease. By decreasing extra salt and water in the body, it also helps to reduce swelling (edema) and breathing problems caused by fluid in the lungs.

Uses and Dosage

Chlorthalidone tablets should be taken orally, usually once a day, with or without food, as directed by your doctor. To get the most benefit from the medication, use it regularly and try to take it at the same time each day. Take chlorthalidone tablet in the morning with a meal. It starts working in about two hours, so do not take it at night; otherwise, you will go to the bathroom more overnight. Avoid taking the tablet within 4 hours of bedtime to avoid having to get up to urinate.

If you have any questions about your dosing schedule or how to use the medication properly, consult your doctor or pharmacist. Avoid taking certain drugs to lower your cholesterol, such as bile acid-binding resins like cholestyramine or colestipol, within 2 hours before or 4 hours after taking Hygroton. Remember to keep taking the medication even if you feel well, as most people with high blood pressure do not feel sick.
