Telmisartan 40 mg + Chlorthalidone 12.5 mg is a combination antihypertensive medicine used to help control high blood pressure in adults when a healthcare professional considers treatment with both ingredients appropriate. Telmisartan works by blocking angiotensin II receptors, helping blood vessels relax and reducing the resistance against which the heart pumps. Chlorthalidone is a thiazide-like diuretic that increases the elimination of sodium and water through the kidneys, helping reduce fluid volume and blood pressure.
By combining these mechanisms, the medicine can provide more effective blood pressure control for suitable patients than either ingredient alone. Maintaining blood pressure within the recommended range can help reduce the long-term risk of cardiovascular complications, including stroke and heart attack.
Possible side effects include dizziness, light-headedness, increased urination, dehydration, and changes in blood potassium or sodium levels. Telmisartan may also affect kidney function and increase potassium levels in certain patients, while chlorthalidone may lower potassium and sodium. Your doctor may monitor blood pressure, kidney function, and electrolytes during treatment.
कैसे उपयोग करें
Follow your prescription: Take the exact dose recommended by your healthcare professional. Do not increase or decrease the dose yourself, even if your blood pressure improves.
Take it consistently: This combination may be prescribed once daily. Follow your product's instructions and take it at approximately the same time each day.
Follow food instructions: It may be taken with or without food, depending on the product instructions. Swallow the tablet with water and do not crush or split it unless your pharmacist confirms that doing so is appropriate.
If you miss a dose: Take it when you remember unless it is nearly time for your next dose. If the next dose is near, skip the missed dose and resume your usual schedule. Do not double the dose.
Monitor blood pressure: Check your blood pressure as advised and attend follow-up appointments. Your doctor may also request blood tests to assess kidney function, sodium, potassium, and other electrolytes.
Maintain appropriate hydration: Chlorthalidone increases urine production and may contribute to dehydration. Follow your doctor's fluid-intake advice, particularly during hot weather, vomiting, or diarrhoea.
Review other medicines: Tell your doctor about all prescription medicines, over-the-counter products, and supplements you take, especially potassium supplements, lithium, other blood pressure medicines, and anti-inflammatory painkillers such as ibuprofen.
Avoid stopping treatment independently: High blood pressure often has no obvious symptoms. Continue treatment unless your healthcare professional advises otherwise.
Recognise warning signs: Seek medical attention for fainting, severe weakness, an irregular heartbeat, or signs of significant dehydration.

Safety advice
Check with your doctor
AlcoholConsult your doctor
Alcohol may increase the blood-pressure-lowering effects of Telmisartan 40 mg + Chlorthalidone 12.5 mg and cause dizziness, light-headedness, or fainting. Excessive alcohol consumption may also worsen dehydration. Avoid heavy drinking, particularly when starting treatment, and consult your doctor about whether alcohol is appropriate for your health condition.
PregnancyConsult your doctor
Telmisartan 40 mg + Chlorthalidone 12.5 mg should not be used during pregnancy because telmisartan can harm the developing baby, particularly during the second and third trimesters. Inform your doctor immediately if you become pregnant or plan to conceive. Your healthcare professional should arrange a suitable alternative treatment promptly.
BreastfeedingConsult your doctor
Breastfeeding while taking Telmisartan 40 mg + Chlorthalidone 12.5 mg requires medical assessment. Information about telmisartan during breastfeeding is limited, and chlorthalidone may enter breast milk and potentially reduce milk production, particularly at higher doses. Ask your doctor about safer alternatives based on your condition and your baby's age and health.
DrivingConsult your doctor
Telmisartan 40 mg + Chlorthalidone 12.5 mg may cause dizziness, light-headedness, or weakness, particularly when starting treatment or when blood pressure becomes too low. Chlorthalidone-related dehydration may also affect alertness. Avoid driving or operating machinery until you know how the medicine affects you, and do not drive if you feel faint or dizzy.
KidneyConsult your doctor
Patients with kidney disease should take Telmisartan 40 mg + Chlorthalidone 12.5 mg under medical supervision. Telmisartan can affect kidney function and potassium levels, while chlorthalidone can cause dehydration and electrolyte disturbances. Your doctor may monitor kidney function, sodium, and potassium before and during treatment. Severe kidney impairment may make this combination unsuitable.
LiverConsult your doctor
Inform your doctor if you have liver disease before taking Telmisartan 40 mg + Chlorthalidone 12.5 mg. Significant liver impairment may increase the risk of complications from fluid or electrolyte changes and low blood pressure. Your healthcare professional should assess your liver condition and determine whether this combination is appropriate or requires an alternative treatment.
