What is Micardis?

Micardis is a prescription medicine used:

  • to treat high blood pressure (hypertension)
  • in certain high risk people aged 55 years and older to help lower their risk of having certain cardiovascular problems such as stroke, heart attack, or death

It is not known if Micardis is safe and effective in children.

What is High Blood Pressure (Hypertension)?

Blood pressure is the force in your blood vessels when your heart beats and when your heart rests. You have high blood pressure when the force is too much. Micardis tablets can help your blood vessels relax so your blood pressure is lower. Medicines that lower your blood pressure lower your chance of having a stroke or heart attack.

High blood pressure makes the heart work harder to pump blood throughout the body and causes damage to the blood vessels. If high blood pressure is not treated, it can lead to stroke, heart attack, heart failure, kidney failure, and vision problems.

What is Cardiovascular Risk?

Patients older than 55 years of age who have been diagnosed with blood vessel disease in the heart, legs, or brain (coronary, peripheral, or cerebral vascular disease) or diabetes with end organ damage (for example: kidney, heart, and brain) are at higher risk of cardiovascular events (for example: death from cardiovascular causes, stroke, and/or heart attack).
