What is this medication?

Montelukast, Singulair
Leukotriene Receptor Antagonist

Officially indicated for allergic rhinitis, asthma, and exercise induced bronchoconstriction.  It may also be prescribed off label for chronic urticaria and neuroinflammation.

“ALERT: US Boxed Warning

Serious neuropsychiatric events:
Serious neuropsychiatric (NP) events have been reported with the use of montelukast. 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 use are currently not well understood.

Because of the risk of NP events, the benefits of montelukast may not outweigh the risks in some patients, particularly when the symptoms of disease may be mild and adequately treated with alternative therapies. Reserve use of montelukast for patients with allergic rhinitis who have an inadequate response or intolerance to alternative therapies. In patients with asthma or exercise-induced bronchoconstriction, consider the benefits and risks before prescribing montelukast.

Discuss the benefits and risks of montelukast with patients and caregivers when prescribing montelukast. Advise patients and/or caregivers to be alert for changes in behavior or new NP symptoms when taking montelukast. If changes in behavior are observed, or if new NP symptoms or suicidal thoughts and/or behavior occur, advise patients to discontinue montelukast and contact a health care provider immediately.”

How does this medication work?

Selective leukotriene receptor antagonist that inhibits the cysteinyl leukotriene receptor. Cysteinyl leukotrienes and leukotriene receptor occupation has been correlated with the pathophysiology of asthma, including airway edema, smooth muscle contraction, and altered cellular activity associated with the inflammatory process, which contribute to the signs and symptoms of asthma.  Montelukast has drawn interest recently due to its ability to increase neurogenesis, decrease microglia activation and restore blood-brain-barrier function.

How should I take this medication?

Oral: Take 10mg once daily.

How to Use:  Can be taken (morning or evening) without regard to food.

Is Montelukast Safe to Use During Pregnancy:  Based on available data, Montelukast has not been linked to an increased risk of teratogenic effects in pregnancy.

What should I watch for while using this medication?

Patients should be instructed to notify their doctor if they experience any behavioral changes (i.e. abnormal dreams, agitation, aggression, anxiety, attention deficit, depression, disorientation, hallucinations, hostility, insomnia, irritability, memory disturbances, restlessness, suicide ideation/behavior).

What if I miss a dose?

If you miss a dose of medication, try to take it as soon as possible.  However, if it is almost time for your next dose, take only that scheduled dose.  Do not take double or extra doses.

How should I store this medication?

Keep out of the reach of children at all times.  Store at room temperature, 59 to 86° F (15 to 30° C).  Protect from light.  Keep the container tightly closed.  Properly dispose of any unused medication after the expiration date.
