How does this medication work? What will it do for me?

Telmisartan belongs to a class of medications known as angiotensin II receptor antagonists. These medications reduce blood pressure by blocking the actions of a chemical (angiotensin II) that causes blood vessels to constrict or tighten. It is used to treat mild to moderate high blood pressure.

When blood pressure is allowed to remain high for a long time, the blood vessels of the heart, kidneys, and brain may become damaged. This puts a person at increased risk for heart attack and stroke as well as kidney failure and blindness. Keeping blood pressure in the normal range can reduce the risk for these conditions.

Telmisartan is also used to reduce the risk of death after a heart attack in people who cannot use another type of medication called angiotensin-converting enzyme inhibitor.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

How should I use this medication?

The recommended adult dose of telmisartan is 80 mg once a day at approximately the same time each day, with or without food. It will take about 2 weeks for reductions in blood pressure to become noticeable and another 2 weeks until the full effects of the medication are realized. People with reduced liver function are usually given 40 mg once daily to start.

It is important to take this medication regularly and to follow your doctor's instructions regarding blood pressure monitoring to ensure that you are getting the maximum benefit from the medication.

If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Store telmisartan at normal room temperature in a dry place (not in the bathroom) and keep it out of the reach of children. Do not remove tablets from their blister-pack until you are ready to take them.

Are there any other precautions or warnings for this medication?


February 4, 2014

Health Canada has issued new restrictions concerning the use of telmisartan. To read the full Health Canada Advisory, visit Health Canada's web site at

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Kidney disease: Telmisartan may worsen kidney disease. People with this condition should be cautious while taking this medication.

Low blood pressure: People with orthostatic hypotension (a sudden drop in blood pressure caused by standing up, which may lead to fainting) should be cautious while taking telmisartan, as it can worsen the condition. The first time this medication is taken, it may cause dizziness, lightheadedness, or fainting. This may be reduced by taking the medication in a sitting position and being careful to rise slowly to a standing position. The dizziness usually improves after the first dose, but if the medication is stopped and then started again, it may reappear. The doctor may also adjust the dose.

Liver disease: People with liver disease should be cautious while taking telmisartan because this medication may be cleared more slowly from the body, resulting in increased side effects.

Pregnancy: Telmisartan should not be taken during pregnancy. If you discover you are pregnant while taking this medication, stop taking the medication and tell your doctor at once.

Breast-feeding: It is not known if telmisartan passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children:The safety and effectiveness of using this medication have not been established for children.

What other drugs could interact with this medication?

There may be an interaction between telmisartan and any of the following:

  • anti-inflammatory medications known as NSAIDs (e.g., naproxen, diclofenac)
  • blood pressure medications known as angiotensin converting enzyme (ACE) inhibitors (e.g., ramipril, enalapril)
  • diuretics (e.g., furosemide)
  • digoxin
  • lithium
  • medications that increase the level of potassium in the blood (e.g., spironolactone, amiloride, triamterene, or salt substitutes that contain potassium)
  • potassium supplements

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

  • stop taking one of the medications,
  • change one of the medications to another,
  • change how you are taking one or both of the medications, or
  • leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
