Zilarta Ct 40/6.25 is used for treatment of hypertension (high blood pressure), especially when single-drug therapy is inadequate; helps reduce risk of cardiovascular events associated with uncontrolled BP (as per physician assessment).
Medically reviewed by Dr. Balaji Krishnan, MBBS · Updated August 2026
Zilarta Ct 40/6.25 contains Telmisartan 40 mg + Chlorthalidone 6.25 mg. It belongs to the Angiotensin II receptor blocker (ARB) + Thiazide-like diuretic class of medicines.
Telmisartan is an angiotensin II receptor blocker (ARB) that relaxes blood vessels by blocking angiotensin II action, lowering blood pressure. Chlorthalidone is a thiazide-like diuretic that increases salt and water excretion, reducing blood volume and BP. Together they provide additive blood pressure control.
Take orally exactly as prescribed, usually once daily at the same time each day; may be taken with or without food. Swallow tablet with water; do not stop abruptly without medical advice. If it causes increased urination, taking it in the morning may be preferred.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Take the missed dose of Zilarta Ct 40/6.25 as soon as you remember. If it is almost time for the next dose, skip the missed one and carry on with the usual schedule. Do not take two doses together to make up for a missed dose.
Taking more Zilarta Ct 40/6.25 than prescribed can be harmful. If you suspect an overdose, contact a doctor or go to the nearest emergency department at once, and carry the pack or strip with you. In India the emergency number is 112.
