Cardiovascular Effects XOPENEX HFA, like other beta-adrenergic agonists, can produce clinically significant cardiovascular effects in some patients, as measured by heart rate, blood pressure, and symptoms.

Hypokalemia As with other beta-adrenergic agonist medications, XOPENEX HFA may produce significant hypokalemia in some patients, possibly through intracellular shunting, which has the potential to produce adverse cardiovascular effects.

Excessive Use and Use with Other Long-Acting Beta 2 -Agonists As with other inhaled beta 2 -adrenergic drugs, formoterol fumarate inhalation solution should not be used more often, at higher doses than recommended, or in conjunction with other medications containing long-acting beta 2 -agonists, as an overdose may result.

Paradoxical Bronchospasm As with other inhaled beta 2 -agonists, formoterol fumarate inhalation solution can produce paradoxical bronchospasm that may be life-threatening.

Cardiovascular Effects Formoterol fumarate inhalation solution, like other beta 2 -agonists, can produce a clinically significant cardiovascular effect in some patients as measured by increases in pulse rate, systolic and/or diastolic blood pressure, and/or symptoms.
