What the FDA labels say
From the Albuterol (Albuterol Sulate HFA) label · effective 2026-01-30
Other short-acting sympathomimetic aerosol bronchodilators should not be used concomitantly with albuterol.
Therefore, Albuterol Sulfate HFA, like all other sympathomimetic amines, should be used with caution in patients with underlying cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.
Coexisting Conditions Albuterol Sulfate HFA, like other sympathomimetic amines, should be used with caution in patients with convulsive disorders, hyperthyroidism, or diabetes mellitus and in patients who are unusually responsive to sympathomimetic amines.
Use of Anti-inflammatory Agents The use of beta-adrenergic agonist bronchodilators alone may not be adequate to control asthma in many patients.
Cardiovascular Effects Albuterol Sulfate HFA, like all other beta 2 -adrenergic agonists, can produce clinically significant cardiovascular effects in some patients such as changes in pulse rate or blood pressure.
From the Formoterol (FORMOTEROL FUMARATE) label · effective 2020-12-15
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.
Doses of the related beta 2 -agonist albuterol, when administered intravenously, have been reported to aggravate preexisting diabetes mellitus and ketoacidosis.
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.
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.
