Who should not take Micardis?

You should not take Micardis if you're allergic to its active ingredient telmisartan. Women who are pregnant should not Micardis. This drug, which treats hypertension (high blood pressure), can be harmful, and even fatal, to a developing fetus.

A doctor will closely monitor anyone with certain medical conditions who take Micardis, especially patients with heart failure or kidney disease who may develop kidney failure. People with liver disease may develop high concentrations of Micardis in the blood.

Micardis could worsen hyperkalemia, in which levels of potassium in the blood become too high. This could lead to nausea, muscle fatigue and abnormal heart rhythms.
