Common Use

Chlorthalidone is used to treat high blood pressure and fluid retention (edema) caused by heart failure, liver disease, or kidney disorders. It works as a diuretic, helping the body eliminate excess salt and water through urine.

Dosage and Direction

Take Chlorthalidone exactly as prescribed, usually once daily in the morning. It can be taken with or without food, but should be taken at the same time each day.

Precautions

Inform your doctor if you have kidney problems, diabetes, or gout. Monitor your blood pressure, electrolyte levels, and kidney function regularly during treatment.

Contraindications

Do not use Chlorthalidone if you are allergic to chlorthalidone or sulfa drugs, or if you are unable to urinate. It is contraindicated in patients with severe kidney or liver dysfunction.

Possible Side Effect

Common side effects include dizziness, increased urination, and low potassium levels. Serious effects may include dehydration, electrolyte imbalance, or irregular heartbeat.

Drug Interaction

Chlorthalidone may interact with lithium, other blood pressure medications, and anti-diabetic drugs. Let your doctor know about all medications and supplements you are taking.

Missed Dose

If you miss a dose, take it as soon as you remember. If it's close to your next dose, skip the missed one—do not take two doses at once.

Overdose

Overdose symptoms may include extreme dizziness, fainting, or electrolyte disturbances. Seek immediate medical help if an overdose is suspected.

Storage

Store at room temperature away from moisture, heat, and light. Keep the medication out of reach of children and pets.
