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 September 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 it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
An overdose of this medicine can cause a severe fall in blood pressure, with dizziness, fainting and a fast or slow pulse. It can cause severe dehydration, a sharp fall in blood pressure and dangerous salt imbalances. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Zilarta Ct 40/6.25 are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

NSAIDs (e.g., ibuprofen, diclofenac) may reduce effect and increase kidney risk, other antihypertensives may add to low BP, lithium (increased lithium levels/toxicity risk), potassium supplements/salt substitutes or potassium-sparing diuretics (risk of high potassium due to telmisartan), corticosteroids or amphotericin B (electrolyte imbalance), antidiabetic medicines (may need dose adjustment), alcohol (increased dizziness/low BP)
Store at room temperature (below 25°C), in a dry place away from moisture and direct light. Keep in original blister pack and out of reach of children.
Blood pressure medicines work only while you take them — do not stop because you feel well. Tell your doctor at once if you become pregnant or are planning a pregnancy. Keep a home blood-pressure record if your doctor has asked for one. Weigh yourself at the same time each day if you have heart failure, and report a rapid gain. Do not add extra salt, and ask before using a potassium-based salt substitute.
