TELSARTAN 20

# Telmisartan 20 mg ## Short Description **Telmisartan 20 mg** is an oral medicine belonging to the **angiotensin II receptor blocker (ARB)** class. It is primarily used to treat **high blood pressure (hypertension)** and, in selected patients, may be used to reduce cardiovascular risk. Telmisartan works by blocking the action of **angiotensin II**, a hormone that causes blood vessels to narrow and promotes sodium and water retention. Blocking this hormone helps blood vessels relax and lowers blood pressure. --- ## Key Benefits * Helps lower **high blood pressure** * Promotes relaxation of blood vessels * Helps reduce the workload on the heart * May be used alone or with other antihypertensive medicines * Provides long-lasting blood pressure control with once-daily dosing in many patients * In appropriate high-risk patients, telmisartan may help reduce the risk of certain cardiovascular events --- ## Uses / Indications ### **Hypertension** Telmisartan 20 mg may be prescribed to lower blood pressure in adults with hypertension. Lowering blood pressure helps reduce the long-term risk of complications such as: * Stroke * Heart attack * Heart failure * Kidney damage ### **Cardiovascular Risk Reduction** In certain adults at high cardiovascular risk, telmisartan may be prescribed to reduce the risk of cardiovascular events when clinically appropriate. ### Other Uses Your healthcare professional may prescribe telmisartan based on your individual cardiovascular and kidney health. --- ## How It Works Telmisartan is an **angiotensin II receptor blocker (ARB)**. Angiotensin II normally binds to **AT1 receptors**, causing: * Narrowing of blood vessels * Increased blood pressure * Sodium and water retention * Increased workload on the heart Telmisartan blocks AT1 receptors. **Telmisartan → blocks angiotensin II at AT1 receptors → blood vessels relax → vascular resistance decreases → blood pressure falls** It does not directly inhibit the angiotensin-converting enzyme (ACE). --- ## Dosage & Administration > **Important:** The appropriate dose depends on your blood pressure, medical condition, kidney and liver function, other medicines, and response to treatment. Follow your healthcare professional's prescription. ### General Adult Dose for Hypertension The usual starting dose of telmisartan for adults with hypertension is often **40 mg once daily**. However, **20 mg once daily** may be prescribed for some patients, particularly when a lower starting dose is appropriate. The dose may be adjusted according to blood pressure response. ### How to Take Telmisartan * Take it once daily at approximately the same time each day. * It may generally be taken **with or without food**. * Swallow the tablet with water. * Take it regularly even if you feel well. * Do not stop treatment without consulting your healthcare professional. ### Missed Dose Take the missed dose when you remember unless it is nearly time for the next scheduled dose. **Do not take two doses together.** ### Kidney or Liver Problems Patients with kidney or liver impairment may require closer monitoring or dosage adjustments. --- ## Side Effects ### Common Side Effects Possible side effects include: * Dizziness * Headache * Fatigue * Low blood pressure * Back pain * Diarrhea * Upper respiratory symptoms Many people tolerate telmisartan well. ### Important Side Effects Telmisartan can occasionally cause: * Significant low blood pressure * Increased potassium levels (**hyperkalemia**) * Changes in kidney function ### Serious Side Effects Seek immediate medical attention for: * Severe dizziness or fainting * Difficulty breathing * Swelling of the face, lips, tongue, or throat * Severe weakness * Irregular heartbeat * Signs of significant kidney problems Serious allergic reactions and angioedema are uncommon but require urgent medical attention. --- ## Precautions & Warnings ### Pregnancy **Telmisartan should not be used during pregnancy.** Medicines that act on the renin-angiotensin system can cause serious injury or death to the developing fetus, particularly during the later stages of pregnancy. If you become pregnant while taking telmisartan, contact your healthcare professional promptly. ### Kidney Function Telmisartan can affect kidney function, particularly in patients who are: * Dehydrated * Taking diuretics * Have renal artery stenosis * Have pre-existing kidney disease Your doctor may monitor kidney function and blood tests. ### High Potassium Telmisartan can increase blood potassium levels. The risk may be higher in people with: * Kidney disease * Diabetes * Heart failure * Existing hyperkalemia Do not use potassium supplements or potassium-containing salt substitutes without medical advice. ### Low Blood Pressure Excessive blood pressure reduction may cause: * Dizziness * Weakness * Fainting The risk may be higher if you are dehydrated or taking diuretics. ### Liver Disease Tell your healthcare professional if you have liver disease. Telmisartan should be used cautiously in patients with significant hepatic impairment. ### Dehydration Severe vomiting, diarrhea, excessive sweating, or inadequate fluid intake can increase the risk of low blood pressure and kidney problems. ### Heart or Kidney Conditions Patients with heart failure, kidney disease, renal artery narrowing, or other cardiovascular conditions may require regular monitoring. --- ## Drug Interactions Tell your doctor or pharmacist about all medicines, supplements, and herbal products you use. ### Potassium Supplements Potassium supplements and potassium-containing salt substitutes can increase the risk of **hyperkalemia**. ### Potassium-Sparing Diuretics Medicines such as: * Spironolactone * Eplerenone * Amiloride * Triamterene may increase potassium levels when combined with telmisartan. ### NSAIDs Non-steroidal anti-inflammatory drugs such as: * Ibuprofen * Naproxen * Diclofenac may reduce the blood-pressure-lowering effect of telmisartan and may increase the risk of kidney problems, particularly in dehydrated or vulnerable patients. ### Lithium Telmisartan may increase **lithium concentrations**, potentially increasing the risk of lithium toxicity. Close monitoring may be required. ### ACE Inhibitors Combining telmisartan with an ACE inhibitor generally increases the risk of: * Low blood pressure * High potassium * Kidney impairment Dual renin-angiotensin system blockade should generally be avoided unless specifically directed by a specialist. ### Aliskiren Combining telmisartan with aliskiren is generally avoided in patients with **diabetes or significant kidney impairment** because of increased risks of hypotension, hyperkalemia, and kidney dysfunction. ### Diuretics Other blood-pressure-lowering medicines and diuretics may enhance the blood-pressure-lowering effect of telmisartan. --- ## Storage Information * Store at **room temperature** according to the manufacturer's instructions. * Keep the tablets in their original packaging. * Protect from moisture and excessive heat. * Keep away from direct sunlight. * Keep the medicine out of reach and sight of children. * Do not use after the expiry date. * Do not use tablets from damaged or tampered packaging. --- ## Prescription Status **Telmisartan 20 mg is generally a prescription medicine.** It should be used under the supervision of a qualified healthcare professional because blood pressure, kidney function, and potassium levels may require monitoring. --- ## Genuine Medicine Assurance When purchasing **Telmisartan 20 mg**: * Purchase from a **licensed pharmacy or authorized medicine supplier**. * Check the medicine name and strength. * Verify the manufacturer's details. * Check the batch/lot number and expiry date. * Ensure the packaging and seal are intact. * Avoid medicines from unauthorized or suspicious sources. * Do not use tablets from damaged or tampered packaging. * If authenticity is uncertain, consult a pharmacist or contact the manufacturer using the details printed on the package. --- # FAQ – Telmisartan 20 mg ### 1.
