Inotropes are non-habit-forming medications that strengthen the contractions of the heart so the heart can pump more blood with fewer beats. Certain inotropes may be prescribed to slow the heart rate of people with an abnormally fast heart rhythm (tachycardia). They may also be prescribed to strengthen the pumping ability of a heart that is weakened because of heart failure.

People taking inotropes should call their  physicians if they notice any change in their heart’s rate, rhythm or force. They may also be instructed by their physician to report a weight gain or loss of more than three pounds in one week. Under no circumstances should patients suddenly stop taking inotropes, because this could cause harmful changes in the heart.
