Black Box Warnings
Long-acting beta2-adrenergic agonists (LABAs) increase the risk of asthma-related death
A placebo-controlled study with another long-acting beta2-adrenergic agonist (salmeterol) showed an increase in asthma-related deaths in patients receiving salmeterol
The finding of an increased risk of asthma-related death with salmeterol is considered a class effect of LABAs, including formoterol, the active ingredient in Perforomist
The safety and efficacy of Perforomist in patients with asthma have not been established
All LABAs, including Perforomist, are contraindicated in patients with asthma without use of a long-term asthma control medication
Tachycardia secondary to heart condition
Coexisting conditions including cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, hypertension, aneurysm, and pheochromocytoma; convulsive disorders; thyrotoxicosis; patients who are unusually responsive to sympathomimetic amines
Risk of transient hypokalemia
May increase risk of severe, potentially fatal asthma attacks
Do not use for relief of acute COPD symptoms
Concomitant short-acting beta2-agonists can be used as needed for acute relief
Life-threatening paradoxical bronchospasm can occur; discontinue immediately
Immediate hypersensitivity reactions may occur (eg, anaphylactic reactions, urticaria, angioedema, rash, bronchospasm)
Pregnancy & Lactation
Pregnancy Category: C
Lactation: not known if excreted in breast milk, use caution
A:Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B:May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.
C:Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.
D:Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.
X:Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.
NA:Information not available.
