What the FDA labels say
From the Formoterol (FORMOTEROL FUMARATE) label · effective 2020-12-15
The increased risk of asthma-related death is considered a class effect of the long-acting beta 2 -adrenergic agonists, including formoterol fumarate inhalation solution.
Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs.
• Use with caution in patients with cardiovascular or convulsive disorders, thyrotoxicosis, or with sensitivity to sympathomimetic drugs.
• Use of long-acting beta 2 -adrenergic agonists (LABA) as monotherapy [without inhaled corticosteroids (ICS)] for asthma is associated with an increased risk of asthma-related death.
Therefore, formoterol fumarate inhalation solution, like other sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.
