What it means
A leukotriene receptor antagonist taken once a day, usually in the evening, for long-term control of asthma, to prevent exercise-induced bronchospasm and for allergic rhinitis. It does not open the airways fast enough to treat an attack. It can rarely cause mood and behavior changes, including agitation, bad dreams, depression and thoughts of suicide.
For the nurse
Teach the client and family to watch for and report changes in mood, sleep or behavior. Keep a rescue inhaler for sudden symptoms. Chewable tablets for children may contain phenylalanine.
