8.1 Pregnancy Risk Summary Available data from published prospective and retrospective cohort studies over decades with montelukast use in pregnant women have not established a drug-associated risk of major birth defects [see Data] .

WARNING: SERIOUS NEUROPSYCHIATRIC EVENTS Serious neuropsychiatric (NP) events have been reported with the use of montelukast sodium. The types of events reported were highly variable, and included, but were not limited to, agitation, aggression, depression, sleep disturbances, suicidal thoughts and behavior (including suicide). The mechanisms underlying NP events associated with montelukast sodium use are currently not well understood [see Warnings and Precautions ( 5.1 )]. 5 WARNINGS AND PRECAUTIONS • Do not prescribe montelukast sodium to treat an acute asthma attack ( 5.2 ). • Advise patients to have appropriate rescue medication available ( 5.2 ). • Inhaled corticosteroid may be reduced gradually. Do not abruptly substitute montelukast sodium for inhaled or oral corticosteroids ( 5.3 ). • Patients with known aspirin sensitivity should continue to avoid aspirin or non-steroidal anti-inflammatory agents while taking montelukast sodium ( 5.4 ). • Systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome, has been reported. These events have been sometimes associated with the reduction of oral corticosteroid therapy ( 5.5 and 6.2 ). 4 CONTRAINDICATIONS • Hypersensitivity to any component of this product. • Hypersensitivity to any component of this product ( 4 ).
