Dosage and method of administration
Chlorthalidone should be taken orally, preferably as a single daily dose at breakfast time.

The lowest effective dose should be used in children. For example, an initial dose of 0.5 to 1mg/kg/48hours and a maximum dose of 1.7mg/kg/48hours have been used.
Geriatric Population
In elderly patients, the elimination of Chlorthalidone is slower than in healthy young adults, although absorption is the same. Therefore, a reduction in the recommended adult dosage may be needed. Close medical observation is indicated when treating patients of advanced age with Chlorthalidone.
Patients with Renal Impairment
Chlorthalidone loses its diuretic effect in patients with creatinine clearance <30 ml/min.
Patients with Hepatic Impairment
No dosage adjustment is necessary in patients with hepatic impairment.
Overdosage
Signs and symptoms
In poisoning due to an overdosage the following signs and symptoms may occur: dizziness, nausea, somnolence, hypovolemia, hypotension and electrolyte disturbances associated with cardiac arrhythmias and muscle spasms.
Treatment
There is no specific antidote to Chlorthalidone. Gastric lavage, emesis or activated charcoal should be employed to reduce absorption. Blood pressure and fluid and electrolyte balance should be monitored and appropriate corrective measures taken. Intravenous fluid and electrolyte replacement may be indicated.

1. What Thaloric Tablets are and what they are used for
Thaloric Tablets belong to a group of medicines called thiazide diuretics.
Thiazide diuretics help to reduce the amount of water in your body. They do this by increasing the amount of water that you pass as urine. They are sometimes called ‘water tablets’.
Thaloric Tablets are used to:
• treat high blood pressure (hypertension)
• treat heart failure
• help reduce the fluid retention that occurs with some kidney or liver diseases
• treat diabetes insipidus (a condition in which an individual produces large amounts of dilute urine and is constantly thirsty).
2. What you need to know before you take Thaloric Tablets
Do not take Thaloric Tablets:
• if you are allergic to Thaloric or sulphonamides such as sulfamethoxazole or any of the other ingredients of this medicine
• if you are not passing any urine at all
• if you have severe kidney or liver problems
• if you have low blood levels of potassium which can cause muscle weakness, muscle twitching or abnormal heartbeat
• if you have low blood levels of sodium which can cause tiredness, confusion, muscle twitching, fits or coma
• if you have high blood levels of calcium which can cause loss of appetite, tiredness or muscle weakness
• if you have ever had gout or kidney stones
• if you have Addison’s disease (which is a condition where your adrenal gland is not producing enough steroids)
• if you are taking lithium.
If any of the above applies to you, or if you are not sure, speak to your doctor or pharmacist before you take Thaloric Tablets.
Warnings and precautions
