6 ADVERSE REACTIONS Long-acting beta 2 -adrenergic agonists, such as formoterol fumarate, as monotherapy (without an inhaled corticosteroid) for asthma increase the risk of asthma-related events.
Formoterol fumarate is not indicated for the treatment of asthma [see WARNINGS AND PRECAUTIONS ( 5.1 )].
Most common adverse reactions ( > 2% and more common than placebo) are diarrhea, nausea, nasopharyngitis, dry mouth, vomiting, dizziness, and insomnia ( 6.2 ) To report SUSPECTED ADVERSE REACTIONS, contact Micro Labs USA Inc., at 1-855-839-8195 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1 Beta 2 -Agonist Adverse Reaction Profile Adverse reactions to formoterol fumarate inhalation solution are expected to be similar in nature to other beta 2 -adrenergic receptor agonists including: angina, hypertension or hypotension, tachycardia, arrhythmias, nervousness, headache, tremor, dry mouth, muscle cramps, palpitations, nausea, dizziness, fatigue, malaise, insomnia, hypokalemia, hyperglycemia, and metabolic acidosis.
6.2 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adults with COPD The data described below reflect exposure to formoterol fumarate inhalation solution 20 mcg twice daily by oral inhalation in 586 patients, including 232 exposed for 6 months and 155 exposed for at least 1 year.
Formoterol fumarate inhalation solution was studied in a 12-week, placebo-and active-controlled trial (123 subjects treated with formoterol fumarate inhalation solution) and a 52-week, active-controlled trial (463 subjects treated with formoterol fumarate inhalation solution).
Patients were mostly Caucasians (88%) between 40 to 90 years old (mean, 64 years old) and had COPD, with a mean FEV 1 of 1.33 L.
Patients with significant concurrent cardiac and other medical diseases were excluded from the trials.
Table 1 shows adverse reactions from the 12-week, double-blind, placebo-controlled trial where the frequency was greater than or equal to 2% in the formoterol fumarate inhalation solution group and where the rate in the formoterol fumarate inhalation solution group exceeded the rate in the placebo group.
5 WARNINGS AND PRECAUTIONS 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.
Like all medications, Formoterol Fumarate can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
