Telmisartan tablet is a long-acting angiotensin II receptor blocker (ARB) primarily prescribed to manage high blood pressure (hypertension), reduce the risk of cardiovascular events, and treat diabetic kidney disease. It is marketed under various brand names, including Micardis. By relaxing blood vessels, Telmisartan helps blood flow more easily, lowering blood pressure and reducing strain on the heart.

What is Telmisartan Tablet?

Telmisartan tablet is a prescription medication belonging to a class of drugs called angiotensin II receptor blockers (ARBs). It works by preventing the action of a substance in the body that causes blood vessels to tighten, thereby lowering blood pressure and improving blood flow.

What are the Uses of Telmisartan?

Telmisartan is mainly used to manage high blood pressure (hypertension) and heart failure, helping reduce the risk of heart attacks, strokes, and kidney damage. It is also effective in protecting kidney function in patients with type 2 diabetes and controlling cardiovascular risks in high-risk individuals.

  • Treats high blood pressure (hypertension)
  • Helps prevent stroke, heart attack, and kidney problems
  • Improves heart function in heart failure patients
  • Protects kidneys in people with type 2 diabetes and hypertension

Conditions Telmisartan Treats

  • Essential hypertension
  • Cardiovascular risk reduction
  • Diabetic nephropathy
  • Heart failure

Secondary Uses of Telmisartan

  • It may be used off-label for conditions like proteinuria
  • Occasionally considered for migraine prevention or post-stroke recovery (as guided by a healthcare provider)

How Does Telmisartan Work?

Telmisartan tablet blocks angiotensin II, a hormone that causes blood vessels to tighten. By blocking its action, Telmisartan relaxes the blood vessels, reduces blood pressure, and improves the heart's efficiency. It also reduces the release of aldosterone, a hormone that can raise blood pressure by increasing salt and water retention.

Telmisartan Dosage Tablet

Telmisartan is usually taken once daily by mouth, with or without food. The dosage varies depending on the medical condition, typically ranging from 20 mg to 80 mg per day. Always follow your doctor's prescription for the most effective and safe use.

  • Typically taken once daily by mouth with or without food.
  • Dosage may vary from 20 mg to 80 mg per day, depending on the condition being treated.
  • Follow your doctor's exact dosage instructions for optimal results.

What Should I Do If I Miss a Dose?

If you miss a dose of the Telmisartan tablet, take it as soon as you remember. However, if it's almost time for your next dose, skip the missed one and continue with your regular schedule. Do not take a double dose to make up for the missed one, as it may increase the risk of side effects. Always follow your doctor's instructions for proper use and dosage of the Telmisartan tablet.

What Happens if I Overdose?

If you overdose on a Telmisartan tablet, you may experience symptoms such as dizziness, fainting, or a rapid drop in blood pressure. In severe cases, it can lead to kidney problems or irregular heartbeat. It's important to seek immediate medical attention if an overdose is suspected. Do not try to treat the overdose at home. Always take Telmisartan exactly as prescribed by your doctor to avoid serious health risks.
