Other adrenergic drugs may potentiate effect. Use with caution. ( 5.3 , 7.1 ) Xanthine derivatives, steroids, diuretics, or non-potassium sparing diuretics may potentiate hypokalemia or ECG changes. Use with caution. ( 5.7 , 7.2 , 7.3 ) MAO inhibitors, tricyclic antidepressants and drugs that prolong QTc interval may potentiate effect on the cardiovascular system. Use with extreme caution. ( 7.4 ) Beta-blockers may decrease effectiveness. Use with caution and only when medically necessary. …

LABA as monotherapy (without inhaled corticosteroid) for asthma increases the risk of serious asthma-related events. ( 5.1 ) Do not initiate formoterol fumarate inhalation solution in acutely deteriorating patients. ( 5.2 ) Do not use for relief of acute symptoms. Concomitant short-acting beta 2 -agonists can be used as needed for acute relief. ( 5.2 ) Do not exceed the recommended dose. Excessive use of formoterol fumarate inhalation solution or use in conjunction with other medications containing long-acting beta 2 -agonists, can result in clinically significant cardiovascular effects, and may be fatal. ( 5.3 , 5.5 ) Life-threatening paradoxical bronchospasm can occur. …
