Micardis (Telmisartan)

What is Micardis (Telmisartan)?

Micardis (telmisartan) is an angiotensin receptor blocker medication that is prescribed for the treatment of hypertension in adult patients above the age of 18 years old. It may also be used for reducing a patient’s risk of heart-related events such as heart attack or stroke. Micardis may be used for treatment alongside additional medications or solely by itself.

How is Micardis Used?

Micardis is a tablet that should be taken orally once per day. This medication should be taken at the same time each day for maximum efficacy, and patients may require two to four weeks before noticing improvement in their condition.

It may be consumed with or without food, and patients should take this medication exactly as instructed by their prescribing physician.

In addition to using Micardis, some patients may be able to improve their condition further by making changes to their diet and exercise habits, avoiding smoking, managing their diabetes, and lowering their cholesterol. Most patients that require the use of Micardis remain on the medication for life.

While using Micardis for treatment, patients will also require regular checks of their kidney function, liver function, and blood pressure.

Storage

Micardis tablets should be stored at room temperature. Ideally, these tablets should remain at a constant temperature of 77°F (25°C). It may be temporarily exposed to temperatures as low as 59°F (15°C) and as high as 86°F (30°C).

Keep this medication out of the reach of children at all times.

As Micardis is a hygroscopic medication, it should not be exposed to moisture. It is recommended to keep Micardis in its original packaging to avoid exposure to any damaging elements.

Uses

Micardis is prescribed for a variety of cardiovascular conditions, including but not limited to:

  • Cardiovascular disease
  • Eclampsia
  • Hypertension
  • Hypertensive congestive heart failure
  • Hypertensive encephalopathy
  • Hypertensive heart disease
  • Hypertensive renal disease
  • Hypertensive retinopathy
  • Pre-eclampsia
  • Reduction of cardiovascular risks
  • Renovascular hypertension

How Does Micardis Work?

As an angiotensin II receptor blocker (ARB), Micardis functions by improving a patient’s blood flow within the body by relaxing the blood vessels. Angiotensin II proteins are those that bind to receptors within a person’s blood and result in the narrowing of the blood vessels. This causes hypertension and an increased risk of adverse cardiovascular events.

By reducing the action of these proteins, ARB medications like Micardis are able to reduce this narrowing of the affected vessels, improve blood flow, and reduce the likelihood of certain cardiovascular events while improving an individual’s overall blood pressure levels.

Dosage

Micardis is available as a tablet in the following strengths:

  • 20 mg
  • 40 mg
  • 80 mg

Patients using Micardis for the treatment of high blood pressure will most commonly take between 40 mg to 80 mg per day to manage their condition. These individuals will often begin with a starting dose of 40 mg until it can be determined how well the medication impacts their hypertension, and their physician will then make adjustments to the dosage as needed.

When used for the purpose of reducing a patient’s risks of stroke or heart attack, individuals taking Micardis will typically start with the maximum dose of 80 mg once per day and continue taking this same dosage for the duration of treatment.

Overdose

Individuals that have somehow taken too much Micardis or have intentionally overdosed on this medication may experience overdose symptoms such as fainting, extreme dizziness, or a rapid heart rate.

If an overdose has occurred or is suspected, the patient’s prescribing physician or the individual’s local Poison Control Center should be contacted. If severe reactions such as difficulty breathing or unconsciousness occur, emergency medical attention should be sought right away.

Warnings & Precautions

The use of Micardis in certain individuals is associated with a number of different risks. Please be sure to discuss any current medication, medical conditions, or relevant medical history with your physician before beginning treatment.

Children

The safety and efficacy of Micardis have not been studied or determined in patients below the age of 18 years.

Impaired Liver Function

As Micardis is processed through the patient’s liver before excretion, patients using this medication that also have hepatic insufficiency or certain biliary obstructive disorders are at risk of not being able to properly and sufficiently eliminate Micardis from their systems as intended. If a patient has a history of liver problems or is currently diagnosed with a related condition that may impact liver function, a lower dose may be required in these individuals, and other dosage modifications may be necessary to safely use the medication.

Kidney Disease

Patients with any history of or current kidney-related impairments or disease are at an increased risk of changes in their renal function when using Micardis. This medication is capable of altering the levels of creatinine, albumin, and potassium in those using it, and this may result in impacts on a patient’s kidney health. Patients with concerns associated with renal function may require regular testing to monitor the impact on the kidneys.

Potassium

Patients using Micardis are advised to avoid supplements, medications, and salt substitutes that may increase their potassium levels, as hyperkalemia is a common risk associated with using an ARB medication. Individuals with heart failure or advanced renal impairment are at an increased risk of developing this condition while using it.

Pregnancy

Micardis is not safe for use during pregnancy and may result in serious injury or death occurring in a developing child, especially if the medication is used during the last two trimesters of pregnancy. Patients that are wanting to become pregnant or may become pregnant while using Micardis are advised to discuss the risks and appropriate measures to be taken regarding treating the condition for which Micardis may be prescribed as well as ensuring a healthy pregnancy.
