Chlorthalidone+telmisartan
About Chlorthalidone+telmisartan
Chlorthalidone+telmisartan is a prescription medicine used to treat high blood pressure (hypertension). By lowering elevated blood pressure, it helps reduce the risk of serious cardiovascular events like strokes and heart attacks. This medication is typically prescribed when a single medicine is not enough to control your blood pressure effectively.
For the best results, take Chlorthalidone+telmisartan consistently at the same time every day, either with or without food. To help this medicine work effectively, your doctor will likely recommend adopting a low-salt diet and maintaining a regular, moderate exercise routine. Consistent daily use is essential, even if you feel completely healthy, as high blood pressure often has no obvious symptoms.
While taking Chlorthalidone+telmisartan, some people may experience mild side effects such as dizziness, fatigue, or an upset stomach. However, you must contact your doctor immediately if you experience serious symptoms like extreme muscle weakness, severe dizziness, or swelling of your face, lips, or throat.
Do not take this if you are pregnant, as this medicine can cause severe harm or death to an unborn baby. Before starting Chlorthalidone+telmisartan, you must talk to your doctor if you have a history of liver damage, severe kidney disease, or diabetes. It is also important to tell your doctor if you have experienced severe dehydration or abnormal electrolyte levels in your blood.
Certain medicines, including pain relievers like NSAIDs, can interact with Chlorthalidone+telmisartan and reduce its effectiveness or increase the risk of kidney damage. Consuming alcohol while taking this medicine can cause your blood pressure to drop too low, leading to severe dizziness or fainting. Pregnant or breastfeeding women should not use this medication, and elderly individuals should use it with caution under close medical supervision.

Drug Interactions
Drug-Drug Interactions
Chlorthalidone+telmisartan may interact with certain medications, potentially affecting its effectiveness or increasing the risk of side effects. Inform your doctor about all prescription medicines, over-the-counter products, and supplements you are taking, including:
- Lithium: Concurrent use may increase lithium levels in the blood, raising the risk of lithium toxicity. Close monitoring is usually required if both medicines are used together.
- NSAIDs (such as ibuprofen, naproxen, or diclofenac): Regular use of nonsteroidal anti-inflammatory drugs may reduce the blood pressure-lowering effects of Chlorthalidone+telmisartan and increase the risk of kidney function impairment.
- Other Blood Pressure Medications: Combining this medicine with other antihypertensive drugs may lead to an excessive reduction in blood pressure, causing dizziness, weakness, or fainting.
- Potassium-Sparing Diuretics or Potassium Supplements: These may increase potassium levels in the blood, potentially leading to hyperkalaemia, which can affect heart rhythm.
- Other Diuretics (Water Pills): Concurrent use may increase the risk of dehydration, electrolyte imbalances, or excessively low blood pressure.
- Antidiabetic Medicines: Blood sugar levels may be affected, and dosage adjustments of diabetes medications may occasionally be necessary.
Drug-Food Interactions
Certain foods and beverages may influence the effects of Chlorthalidone+telmisartan. Consider the following precautions:
- Alcohol: Alcohol may enhance the blood pressure-lowering effect of this medicine, increasing the risk of dizziness, light-headedness, or fainting, particularly when standing up suddenly.
- Salt Substitutes Containing Potassium: Potassium-based salt substitutes should be used cautiously, as they may increase blood potassium levels and raise the risk of hyperkalaemia.
- Maintain Adequate Hydration: Excessive fluid loss from vomiting, diarrhoea, or inadequate fluid intake may increase the risk of dehydration and low blood pressure during treatment.
Drug-Disease Interactions
Certain medical conditions may require special precautions or monitoring while taking Chlorthalidone+telmisartan. Tell your doctor if you have any of the following:
- Kidney Disease: This medicine may affect kidney function, particularly in patients with existing kidney impairment. Regular monitoring of kidney function may be required.
- Liver Disease: Patients with liver impairment may experience altered drug metabolism and may require careful dose adjustment and monitoring.
- Diabetes: The chlorthalidone component may influence blood glucose levels, making periodic monitoring and possible adjustments to diabetes treatment necessary.
- Gout: Chlorthalidone can increase uric acid levels in the blood, potentially triggering or worsening gout attacks.
- Electrolyte Imbalances: Conditions associated with abnormal potassium, sodium, magnesium, or calcium levels may be worsened and require monitoring during treatment.

Patients Concern
Disease/Condition Glossary
Hypertension: It is a chronic condition when blood pressure is too high. This condition can lead to hardened arteries (blood vessels), decreasing the blood and oxygen flow to the heart. Blood pressure is the measurement of the force that our heart uses to pump blood to all parts of the body. Raised blood pressure can cause chest pain (angina) and heart attack (when the blood supply to the heart is blocked). Additionally, high blood pressure also causes brain damage (stroke) and kidney failure. High blood pressure can be diagnosed with the help of a blood pressure monitor or sphygmomanometer. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is when your heart is at the resting stage between heartbeats. If your blood pressure is 140/90 mm of Hg, it means the systolic pressure is 140 mm of Hg, and diastolic pressure is 90 mm of Hg. Ideal blood pressure should be between 90/60 mm of Hg and 120/80 mm of Hg.
