Telmisartan
About Telmisartan
Telmisartan is a prescription medication primarily used to treat high blood pressure (hypertension). It is also prescribed to lower the risk of major cardiovascular events, such as heart attacks or strokes, in individuals who are at high risk. By keeping your blood pressure within a healthy range, this medicine helps protect your heart, kidneys, and brain from long-term damage.
To get the best results, you should take Telmisartan consistently every day, preferably at the same time. You can take this tablet with or without food, as eating does not affect how the medicine is absorbed. Combining your daily dose with a low-sodium diet and regular physical activity can significantly improve how well this medicine controls your blood pressure.
While Telmisartan is generally well-tolerated, some people may experience mild side effects like dizziness, back pain, or sinus congestion. However, you should contact your doctor immediately if you experience serious symptoms, such as swelling of your face or throat, severe muscle weakness, or a slow, irregular heartbeat.
Do not take this medicine if you are pregnant, as it can cause serious harm or death to an unborn baby. You should also avoid this medicine if you have a known allergy (hypersensitivity) to Telmisartan or any of its ingredients. In addition, Telmisartan should not be used together with aliskiren in patients with diabetes and is generally avoided in certain patients with significant kidney impairment unless specifically recommended by a healthcare professional. You should also talk to your doctor before starting Telmisartan if you have a history of liver damage, kidney problems, or severe dehydration.
This medicine can interact with other substances; for example, taking it with potassium supplements can lead to dangerously high potassium levels in your blood. If you are breastfeeding or are an older adult, consult your healthcare provider to ensure this treatment is safe for your specific situation.

Patients Concern
Disease/Condition Glossary
High Blood Pressure (Hypertension): When blood pressure rises, too much force is exerted on the lining of the arteries, causing the heart to work harder to pump blood throughout the body. This results in damage to the blood vessels. If high blood pressure is left untreated, it can lead to stroke, heart attack, heart failure, kidney failure, and eye problems.
Cardiovascular risk: It is usually diagnosed in patients older than 55 years of age and is characterised by blood vessel disease in the heart, brain, or legs (coronary, peripheral, or cerebral vascular disease) or diabetes with organ damage.
FAQs
Telmisartan is used to treat hypertension (high blood pressure) and to reduce the risk of heart attack or stroke in adults.
No, you are not recommended to take Telmisartan with antidepressants or barbiturates as it may cause dizziness. However, please consult your doctor before taking Telmisartan with any other medicines.
Telmisartan contains Telmisartan, which works by blocking the action of a hormone called angiotensin II in the body. This hormone causes blood vessels to narrow, leading to high blood pressure. By blocking this action, Telmisartan widens and relaxes blood vessels, lowering high blood pressure.
No, you are not recommended to take ibuprofen with Telmisartan as co-administration of these two medicines may reduce the effect of Telmisartan and increase the risk of impaired kidney function. However, if you experience loss of appetite, sudden weight loss or weight gain, weakness, muscle cramps, vomiting, nausea, decreased or increased urination, irregular heart rhythm and fluid retention, please consult a doctor immediately. If you are supposed to use these medicines together, you should contact your doctor to adjust the dose to be used safely.
Telmisartan should be taken as advised by the doctor. It is better to take it at the same time daily as it will help you remember to take the medicine.
Do not worry as Telmisartan may not cause weight gain. However, consult the doctor if you notice unexplained weight gain as it could be a sign of kidney problems.
Telmisartan might lower blood glucose levels. Therefore, inform the doctor if you have diabetes. Regular monitoring of blood sugar levels is advised.
Yes, Telmisartan may cause hyperkalemia (high potassium level in blood). The doctor may monitor your potassium levels as needed.
No, Telmisartan does not work by causing excessive urination. It works by relaxing the blood vessels and improving blood flow.
Telmisartan can be taken with or without food.
Side effects of Telmisartan are diarrhoea, sinus infection, back pain, or low blood pressure. Most of these side effects may not require medical attention and resolve over time. However, if the side effects persist, please consult your doctor.
Telmisartan may interact with other medications, particularly NSAIDs (painkillers). Therefore, consult the doctor before taking other medications while on treatment with Telmisartan.
Seek immediate medical attention if you overdose on Telmisartan. Overdose may cause low blood pressure, dizziness and slow/fast heartbeat.
No, you should not take Telmisartan if you are pregnant. This medication can cause serious harm, birth defects, or death to an unborn baby. If you become pregnant or plan to become pregnant while taking this medicine, stop taking it and contact your doctor immediately.
You may begin to see an initial reduction in blood pressure within 1 to 2 weeks of starting Telmisartan. However, the full blood pressure-lowering effect may take 4 to 8 weeks of consistent daily use. Continue taking the medicine exactly as prescribed and attend your follow-up appointments so your doctor can assess your response to treatment.
It is best to avoid or strictly limit alcohol while taking Telmisartan. Alcohol can increase the blood pressure-lowering effect of this medicine, which may cause severe dizziness, lightheadedness, or fainting. Talk to your doctor or pharmacist about safe alcohol limits.
Yes, you should avoid using salt substitutes that contain potassium, as well as taking potassium supplements without medical advice. These can interact with Telmisartan and cause potassium levels in your blood to become dangerously high. Talk to your doctor for personalised dietary advice.
Dizziness is a common side effect, especially when you first start taking Telmisartan or when your dose is increased. Try to rise slowly from a sitting or lying position. If the dizziness is severe, makes you feel faint, or does not improve over time, talk to your doctor.
No, you should not stop taking Telmisartan even if you feel well and your blood pressure readings are normal. High blood pressure often has no symptoms, and stopping this medicine abruptly can cause your blood pressure to rise quickly again. Talk to your doctor before making any changes.
Yes, in some cases, Telmisartan can affect how your kidneys work, especially if you already have kidney disease or are dehydrated. Your doctor will likely perform routine blood tests to check your kidney function while you are on this medication. Talk to your doctor if you notice changes in your urination.
You should avoid taking nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen regularly while taking Telmisartan. These painkillers can make your blood pressure medication less effective and increase the risk of kidney damage. Talk to your doctor or pharmacist for safe pain relief alternatives.
