Singulair, known generically as montelukast, is a medication that changed the management of asthma and allergic rhinitis since its approval by the U.S. Food and Drug Administration in 1998. Developed by Merck and Company, this oral drug belongs to a class of medications called leukotriene receptor antagonists. It works by blocking the action of leukotrienes, inflammatory chemicals released during allergic or asthmatic responses. When leukotrienes bind to receptors in the airways, they cause bronchoconstriction, mucus secretion, and airway inflammation. Montelukast prevents this binding, helping keep airways open, reducing inflammation, and alleviating symptoms of both asthma and seasonal allergies. Over two decades, it has become one of the most widely prescribed medications for respiratory conditions worldwide, available in chewable tablets, granules, and regular tablets for adults and children as young as twelve months.
The mechanism of action of montelukast is both elegant and specific. Leukotrienes are synthesized from arachidonic acid through the 5-lipoxygenase pathway and released from mast cells, eosinophils, and basophils during inflammation. Two main leukotriene receptor types exist: CysLT1 and CysLT2. Montelukast selectively antagonizes the CysLT1 receptor found predominantly in airway smooth muscle cells and on inflammatory cells such as eosinophils. When montelukast has this receptor, leukotrienes cannot bind and trigger downstream effects, resulting in reduced airway edema, decreased smooth muscle contraction, and diminished mucus hypersecretion. Unlike bronchodilators that provide only acute relief by relaxing already constricted airways, montelukast addresses the underlying inflammatory process, making it valuable as a controller medication for persistent asthma. This fundamental difference in mechanism explains why montelukast is used for long-term prevention rather than acute symptom relief, and why it must be taken consistently every day to maintain its protective effects.
Clinical applications in asthma management
Asthma is a chronic respiratory condition characterized by airway inflammation, hyperresponsiveness, and reversible airflow obstruction. It affects approximately 262 million people worldwide and causes around 455,000 deaths annually according to the Global Asthma Report. Montelukast is indicated for the prophylaxis and chronic treatment of asthma in adults and pediatric patients. Clinical guidelines from the National Institutes of Health and the Global Initiative for Asthma position montelukast as an alternative first-line controller medication for mild persistent asthma, particularly in patients who cannot or prefer not to use inhaled corticosteroids. For patients with more severe asthma, montelukast can be used as add-on therapy to inhaled corticosteroids, potentially allowing for lower steroid doses while maintaining asthma control. This positioning reflects medication’s proven efficacy alongside its favorable safety and convenience profile.
Numerous randomized controlled trials have demonstrated the efficacy of montelukast in improving lung function and reducing asthma symptoms. A landmark study published in the New England Journal of Medicine in 1998 showed that montelukast improved forced expiratory volume in one second, reduced daytime asthma symptoms, decreased nighttime awakenings, and reduced the need for rescue beta-agonist inhalers compared to placebo. More recent meta-analyses confirm that montelukast reduces exacerbation rates by approximately 40 to 50 percent in patients with mild to moderate asthma. The medication reduces eosinophilic inflammation in the airways, as measured by decreased eosinophil counts in sputum and blood samples. This anti-inflammatory effect is particularly beneficial for patients with allergic asthma, where eosinophilic inflammation plays a central pathogenic role. The consistency of these findings across diverse patient populations and study designs shows the reliability of montelukast as a therapeutic option.
One key advantage of montelukast is its oral route of administration. Many asthma controller medications, particularly inhaled corticosteroids, require proper inhaler technique for optimal drug delivery. Studies have shown that up to 70 percent of patients use their inhalers incorrectly, leading to suboptimal disease control. Montelukast tablets eliminate this issue entirely, as they are simply swallowed once daily. A retrospective cohort study analyzing prescription claims data found that adherence rates for montelukast were higher than for inhaled corticosteroids over a twelve-month period. Better adherence naturally translates to better clinical outcomes, including fewer emergency department visits and hospitalizations for asthma exacerbations. The simplicity of oral dosing also makes montelukast particularly suitable for elderly patients who may struggle with the coordination required for inhaler use, and for children who may be frightened by or resistant to inhaler devices.
The recommended dosage of montelukast for asthma is straightforward. For adults and adolescents fifteen years and older, the standard dose is one 10 mg tablet taken once daily in the evening. For children six to fourteen years of age, the recommended dose is one 5 mg chewable tablet daily, also taken in the evening. For children twelve months to five years of age, a 4 mg chewable tablet or 4 mg oral granule packet is used. The evening dosing schedule is based on the observation that asthma symptoms often worsen at night and in the early morning hours, a phenomenon known as nocturnal asthma. By taking montelukast in the evening, peak drug concentrations in the blood align with the period when patients typically experience the most significant symptoms. Clinical studies have confirmed that evening dosing provides superior control of nocturnal asthma symptoms compared to morning dosing. Montelukast is not a rescue medication and should not be used for acute attacks. Patients experiencing sudden worsening of asthma symptoms should use their short-acting beta-agonist inhaler, such as albuterol, and seek medical attention if symptoms do not resolve.
Use in allergic rhinitis
Beyond its role in asthma management, montelukast is also approved for the relief of symptoms of seasonal allergic rhinitis, commonly known as hay fever, and perennial allergic rhinitis. Allergic rhinitis affects between 10 and 30 percent of the global population and involves sneezing, nasal congestion, rhinorrhea, nasal itching, and often associated ocular symptoms such as itchy eyes and tearing. The pathophysiology of allergic rhinitis involves the release of histamine and leukotrienes from mast cells upon exposure to allergens such as pollen, dust mites, or pet dander. While antihistamines effectively address sneezing and itching, they are less effective for nasal congestion, which is primarily mediated by leukotrienes. Montelukast complements antihistamines by targeting this leukotriene-mediated congestion, providing a more comprehensive approach to symptom management than either drug class alone.
For allergic rhinitis, the dosage of montelukast is the same as for asthma: 10 mg daily for adults and adolescents, with lower doses for children. However, the timing of dosing may differ. While evening dosing is recommended for asthma, patients using montelukast solely for allergic rhinitis can take it at any consistent time of day. Many clinicians recommend taking it in the evening regardless, especially for patients with both conditions, as it simplifies the regimen and addresses nocturnal worsening of both asthma and nasal symptoms. Clinical trials evaluating montelukast for seasonal allergic rhinitis have consistently shown significant improvements in daytime nasal symptoms, eye symptoms, and overall quality of life compared to placebo. A multicenter, double-blind, randomized trial involving over 1,300 patients with spring seasonal allergic rhinitis found that montelukast reduced the composite symptom score throughout the treatment period. When combined with loratadine, a second-generation antihistamine, the efficacy was superior to either agent alone, particularly for nasal congestion and eye symptoms, demonstrating the synergistic potential of combination therapy.
For perennial allergic rhinitis, which occurs year-round due to indoor allergens such as dust mites and pet dander, montelukast has also demonstrated efficacy. A twelve-week randomized controlled trial in patients with perennial allergic rhinitis showed that montelukast improved daytime nasal symptoms, nighttime symptoms, and overall rhinitis-specific quality of life scores compared to placebo. The medication was well tolerated throughout the study period, with an adverse event profile similar to placebo. Intranasal corticosteroids remain the most effective monotherapy for allergic rhinitis, but many patients dislike using nasal sprays due to discomfort, bad taste, or concerns about long-term side effects. Montelukast offers an effective alternative for these patients. For patients with concomitant asthma and allergic rhinitis, which is extremely common, montelukast has the added advantage of treating both conditions simultaneously with a single daily tablet, simplifying medication regimens, reducing polypharmacy, and improving overall disease control.
Pediatric use and special populations
Montelukast has a particularly important role in pediatric asthma management. Asthma is the most common chronic disease in children, affecting approximately 5 to 10 percent of children worldwide. The management of asthma in children presents unique challenges, including difficulty with inhaler technique, fear of inhaler devices, and the potential growth-suppressing effects of long-term inhaled corticosteroid use. Montelukast addresses many of these concerns through its oral formulation, which is much easier for children and their caregivers to administer. The availability of chewable tablets in grape flavor and oral granules that can be mixed with soft foods has further improved acceptability among young children. an important study in children aged six to fourteen years demonstrated significant improvements in FEV1, reduced daytime asthma symptoms, and decreased beta-agonist use compared to placebo. For younger children aged two to five years, studies have shown that montelukast reduces daytime and nighttime asthma symptoms, decreases the need for rescue medications, and improves caregivers global evaluations of their children’s asthma control.
One of the most significant benefits of montelukast in pediatric asthma is its potential to reduce the need for inhaled corticosteroids. While inhaled corticosteroids are highly effective and generally safe, concerns about growth suppression have led to interest in steroid-sparing strategies. A study published in the Journal of Allergy and Clinical Immunology showed that the addition of montelukast to low-dose inhaled corticosteroid therapy allowed for a significant reduction in the corticosteroid dose while maintaining asthma control in children. This steroid-sparing effect is particularly valuable in children who require long-term controller therapy, as it minimizes cumulative steroid exposure during critical periods of growth and development. In elderly patients with asthma, who often have multiple comorbidities and take numerous medications, montelukast offers a favorable safety profile with minimal drug interactions. Pharmacokinetic studies show that the plasma concentrations of montelukast in elderly subjects were similar to those in younger adults, and no dose adjustment is necessary based on age alone.
Pregnant women with asthma face particular challenges, as uncontrolled asthma during pregnancy is associated with increased risks of preeclampsia, preterm birth, low birth weight, and perinatal mortality. The safety of montelukast during pregnancy has been evaluated in several observational studies. A prospective cohort study published in the Journal of Allergy and Clinical Immunology found no increased risk of major congenital malformations compared to the general population. The FDA categorizes montelukast as Pregnancy Category B, indicating that animal reproduction studies have not demonstrated fetal risk and adequate human studies are available. However, montelukast should be used during pregnancy only if clearly needed, and the lowest effective dose should be used. Uncontrolled asthma poses greater risks to both mother and fetus than the potential risks of medication exposure, so maintaining adequate asthma control during pregnancy remains the priority.
Pharmacokinetics and drug interactions
Understanding the pharmacokinetic properties of montelukast helps clinicians optimize its use. After oral administration, montelukast is rapidly absorbed from the gastrointestinal tract, reaching peak plasma concentrations within two to four hours. The absolute bioavailability of the 10 mg tablet is approximately 64 percent, and the presence of a standard meal does not affect its absorption. Montelukast is metabolized in the liver, primarily by the cytochrome P450 enzyme system, specifically the CYP3A4 and CYP2C9 isoenzymes. After metabolism, the drug and its metabolites are excreted almost exclusively in the bile and subsequently eliminated in the feces. Less than 0.2 percent of a dose is recovered in the urine, indicating that renal excretion plays a negligible role. This hepatic metabolism profile has important clinical implications. Patients with moderate hepatic impairment have approximately 56 percent higher plasma concentrations compared to healthy subjects. However, no dose adjustment is recommended for patients with mild to moderate hepatic impairment, and there are no data available for patients with severe hepatic impairment.
The elimination half-life of montelukast averages approximately 2.7 to 5.5 hours in healthy adults. Despite this relatively short half-life, the drug is administered once daily because its pharmacodynamic effect at the CysLT1 receptor persists beyond its presence in the plasma. This prolonged effect is attributed to the slow dissociation of montelukast from the leukotriene receptor, meaning that even after plasma concentrations decline, the receptor remains occupied and functional blockade continues. Drug interaction studies have evaluated the potential for montelukast to interact with other commonly used medications. Montelukast does not inhibit or induce CYP enzyme activity at therapeutic concentrations, which means it has a low potential for causing clinically significant drug interactions. Studies with warfarin, digoxin, theophylline, and oral contraceptives have shown no clinically important interactions. However, because montelukast is metabolized by CYP3A4 and CYP2C9, strong inhibitors of these enzymes could theoretically increase montelukast concentrations. In practice, coadministration with gemfibrozil, a potent CYP2C9 inhibitor, resulted in a 4.5-fold increase in montelukast plasma concentrations, but this was not associated with increased adverse events and no dose adjustment is recommended. Phenobarbital and other antiepileptic drugs that induce CYP3A4 may reduce montelukast exposure by approximately 40 percent, though this is not usually clinically significant in most patients.
Safety profile and adverse effects
Montelukast is generally well tolerated, with a safety profile that compares favorably to many other asthma controller medications. In clinical trials, the most common adverse events were headache, abdominal pain, cough, and influenza-like symptoms. These events were generally mild and transient, and the overall incidence of adverse events in montelukast-treated patients was similar to that in placebo-treated patients. The favorable safety profile extends to long-term use, with studies of up to two years of continuous treatment showing no accumulation of adverse events or emergence of delayed toxicities. In adults, headache is the most commonly reported adverse event, occurring in approximately 18 percent of patients compared to 15 percent in the placebo group. Upper respiratory tract infection, cough, and pharyngitis are also reported at rates slightly above placebo, although it can be difficult to distinguish these events from the underlying asthmatic condition being treated. In pediatric patients, the most common adverse events include headache, cough, abdominal pain, and diarrhea, with no unique pediatric adverse effects identified in clinical trials or postmarketing surveillance.
Montelukast avoids class-specific toxicities associated with other asthma medications. Inhaled corticosteroids, while effective, carry risks of oral candidiasis, dysphonia, and with long-term high-dose use, potential growth suppression in children and decreased bone mineral density in adults. Inhaled beta-agonists can cause tachycardia, tremor, and hypokalemia, particularly at high doses. Montelukast avoids these class-specific toxicities, making it an attractive option for patients who are intolerant of or have contraindications to other asthma medications. This favorable safety profile contributes to the high adherence rates observed with montelukast in real-world clinical practice.
The most serious adverse effect associated with montelukast is neuropsychiatric events, including agitation, aggression, depression, sleep disturbances, suicidal thoughts, and suicidal behavior. These events prompted the FDA to issue a Boxed Warning in March 2020, the agency’s strongest safety warning. The warning was based on a comprehensive review of adverse event reports submitted to the FDA Adverse Event Reporting System and published literature. Between 1998 and 2019, the FDA identified 82 completed suicides among montelukast users, although establishing causality is difficult given background rate of suicide in the general population and the potential confounding effects of asthma severity on mental health. The neuropsychiatric effects of montelukast appear to be idiosyncratic, meaning they are not dose-dependent and cannot be predicted by patient demographics. They can occur at any time during treatment, from the first dose to months or years after starting. Most reported cases have involved onset within the first few weeks of treatment. The exact mechanism by which montelukast might cause neuropsychiatric effects is unknown, but it may relate to the presence of CysLT receptors in the central nervous system and the potential for montelukast to cross the blood-brain barrier. Rodent studies have identified CysLT1 receptors in the hippocampus, cerebellum, and cortex, areas involved in mood regulation and behavior.
Following the Boxed Warning, clinical practice guidelines have been updated to recommend careful discussion of neuropsychiatric risks with patients and caregivers before prescribing. Patients and caregivers should be advised to be alert for behavioral changes, including agitation, aggression, depression, sleep talking, and suicidal ideation, and to discontinue montelukast and seek medical attention if such changes occur. The absolute risk of serious neuropsychiatric events appears to be very low. A large observational study using data from Swedish national registries analyzing over 300,000 patients exposed to montelukast found no significant increase in the risk of depression, anxiety disorders, or suicide compared to unexposed asthmatic controls. Other population-based studies have yielded mixed results, with some finding small increases in certain neuropsychiatric outcomes and others finding no association. The heterogeneity of these findings likely reflects differences in study design, population characteristics, and outcome definitions. Nevertheless, the FDA Boxed Warning has had a significant impact on prescribing patterns, with a noticeable decrease in montelukast prescriptions following its issuance, particularly in children.
Comparison with other asthma controller medications
To understand the place of montelukast in asthma therapy, it is useful to compare it with other controller medications. Inhaled corticosteroids such as fluticasone and budesonide are considered the gold standard for persistent asthma. They directly suppress airway inflammation by reducing the production of inflammatory cytokines and decreasing eosinophil survival. In comparative studies, low-dose inhaled corticosteroids have generally been more effective than montelukast as monotherapy for improving lung function, reducing symptoms, and preventing exacerbations. A meta-analysis of randomized controlled trials found that inhaled corticosteroids reduced the risk of asthma exacerbations by approximately 55 percent compared to placebo, while montelukast reduced the risk by approximately 40 percent. However, the magnitude of this difference is modest, and many patients achieve adequate control with montelukast alone. Combination therapy with montelukast and inhaled corticosteroids has been evaluated as an alternative to increasing the inhaled corticosteroid dose in patients with uncontrolled asthma. The COMPACT trial randomized patients with uncontrolled asthma on low-dose inhaled corticosteroids to either add montelukast or double their inhaled corticosteroid dose. The study found that the addition of montelukast provided similar improvements in asthma control compared to doubling the corticosteroid dose, supporting its role as a steroid-sparing agent.

Long-acting beta-agonists such as salmeterol and formoterol are another class of medications used as add-on therapy to inhaled corticosteroids. Comparative studies have shown that adding a long-acting beta-agonist to inhaled corticosteroids is generally more effective for improving lung function and preventing exacerbations than adding montelukast. However, long-acting beta-agonists carry a boxed warning about an increased risk of asthma-related death when used without concomitant inhaled corticosteroids, and they are not effective for all patients. Montelukast remains a useful alternative add-on therapy for patients who have contraindications to or prefer to avoid long-acting beta-agonists. Compared to zafirlukast, another leukotriene receptor antagonist, montelukast offers significant advantages including once-daily dosing versus twice-daily, no food effect on absorption, and fewer drug interactions, making it the preferred agent in its class. Another leukotriene-modifying drug, zileuton, inhibits leukotriene synthesis rather than blocking receptors, but requires multiple daily doses, has significant drug interactions, and requires monitoring of liver enzymes, making it a less attractive option for most patients.
Patient education and counseling points
Effective use of montelukast requires appropriate patient education. Patients must understand that montelukast is a preventive medication, not a rescue treatment for acute symptoms. They should continue taking montelukast even when they feel well, as the medication works to prevent symptoms from occurring rather than treating them after they develop. Discontinuation of montelukast can lead to worsening asthma control within one to two weeks. Patients should also be advised that montelukast does not replace their rescue inhaler, which should be carried at all times for immediate relief of breakthrough symptoms. Administration instructions vary by formulation. The 10 mg tablet should be swallowed whole with water. Chewable tablets should be chewed thoroughly before swallowing. Oral granules can be administered either directly into the mouth or mixed with a spoonful of cold or room temperature soft food such as applesauce, ice cream, rice, or yogurt. The mixture should not be stored for future use and should be administered within fifteen minutes of opening the packet.
Storage requires controlled room temperature between 20 and 25 degrees Celsius in a dry place protected from light, moisture, and heat. The medication should be kept in its original blister packaging until ready to use, as exposure to air and moisture can degrade the active ingredient. Common mild adverse effects such as headache and abdominal pain typically resolve on their own and do not require medical intervention. Patients should seek immediate medical attention if they experience symptoms of a severe allergic reaction, including rash, hives, difficulty breathing, or swelling of the mouth, face, lips, or tongue. Most patients and caregivers should be alerted to the possibility of neuropsychiatric adverse effects and instructed to stop montelukast and contact their healthcare provider immediately if they notice any unusual behavioral changes, mood disturbances, or thoughts of self-harm. Patients with asthma should also have a written asthma action plan that specifies what to do when symptoms worsen, including when to increase controller medications and when to seek emergency care. Regular follow-up appointments are essential for monitoring asthma control, assessing the ongoing need for montelukast, and adjusting the treatment regimen as needed.
Generic availability and cost considerations
Montelukast became available as a generic medication following the expiration of its patent protection in 2012. The availability of generic montelukast has reduced the cost of this medication, making it accessible to a broader population of patients. Generic montelukast is manufactured by numerous pharmaceutical companies worldwide under various trade names, but the active ingredient and therapeutic effects are identical to the brand-name Singulair. In the United States, generic montelukast is covered by most insurance plans, including Medicare Part D and many Medicaid programs, often with a low or zero copayment. The cash price for a thirty-day supply of generic montelukast is typically between ten and thirty dollars, depending on the pharmacy and location, making it one of the more affordable asthma controller medications available. This affordability has important public health implications, as it lowers barriers to treatment adherence, particularly for uninsured and underinsured patients who might otherwise forgo controller therapy due to cost concerns. Cost-effectiveness analyses have generally found montelukast to be a cost-effective treatment option for asthma, with the advantage of improved adherence partially offsetting its slightly lower efficacy compared to inhaled corticosteroids in controlled trials.
Global perspectives and regulatory status
Montelukast is approved for use in over 100 countries worldwide and is included on the World Health Organization Model List of Essential Medicines, recognizing its importance as a treatment for asthma and allergic rhinitis. Despite widespread approval, regulatory authorities in different countries have responded differently to the neuropsychiatric safety concerns. The FDA issued a Boxed Warning in 2020, the most severe warning level. The European Medicines Agency also conducted a review of montelukast neuropsychiatric risks, resulting in a label update in 2019 that strengthened warnings, but stopped short of issuing a boxed warning equivalent. Health Canada updated its labeling in 2020 to include strengthened warnings about neuropsychiatric events and did not issue a boxed warning. In some countries, particularly in Asia and Africa, montelukast is available over the counter without a prescription, while in the United States, Canada, and most European countries, it requires a prescription. Proponents of over-the-counter availability argue that montelukast has a favorable safety profile and low abuse potential, while opponents counter that the medication carries significant risks and that patients may not appropriately self-manage asthma without medical supervision.
During the COVID-19 pandemic, in vitro studies suggested that montelukast might have antiviral activity against SARS-CoV-2. Computational modeling indicated that montelukast could bind to the main protease of the virus and potentially inhibit viral replication. A randomized controlled trial published in 2022 found that hospitalized COVID-19 patients treated with montelukast had a shorter time to clinical improvement compared to standard care alone, although the results were preliminary and require confirmation in larger trials. Montelukast is not currently recommended as a standard treatment for COVID-19 by any major health authority, but this research shows the potential for repurposing this well-established medication for new therapeutic indications. Ongoing research continues to explore new applications for montelukast beyond asthma and allergic rhinitis. Preclinical studies have suggested potential benefits in neurodegenerative diseases such as Alzheimer’s disease and Parkinson’s disease, based on the role of leukotrienes in neuroinflammation. A retrospective cohort study found that patients with Alzheimer’s disease who used montelukast had slower cognitive decline compared to non-users, although confounding by indication remains a concern. Clinical trials are currently underway to evaluate montelukast for traumatic brain injury, multiple sclerosis, urticaria, atopic dermatitis, sinusitis, and eosinophilic esophagitis, with mixed results so far.
Practical guidance for patients and healthcare providers
For patients considering montelukast therapy, a thorough discussion with a healthcare provider is essential. Patients should disclose their complete medical history, including any history of psychiatric conditions, as this may influence the risk-benefit assessment. Liver function should be assessed before initiating therapy, although routine monitoring of liver enzymes during treatment is not required. Patients should also inform their provider about all medications they are taking to identify any potential drug interactions. When initiating montelukast therapy, patients should take the medication in the evening and record their asthma symptoms, peak flow measurements, and rescue inhaler use in a diary for the first several weeks. This baseline data helps establish whether the medication is effectively controlling symptoms. Follow-up should be scheduled within four to eight weeks of starting therapy to assess response. If adequate asthma control is achieved, continued use at the same dose is appropriate. If control is inadequate, the healthcare provider may consider increasing the dose, adding another controller medication, or switching to an alternative regimen.
Discontinuation of montelukast should be done under medical supervision, particularly in patients with moderate to severe asthma, as abrupt discontinuation can lead to rebound worsening within one to two weeks. Alternative controller therapy should be initiated before or simultaneously with montelukast discontinuation to maintain asthma control. Montelukast is also approved for the prevention of exercise-induced bronchoconstriction in patients aged six years and older. Leukotrienes are important mediators of exercise-induced bronchoconstriction, and montelukast attenuates the decline in lung function after exercise, with effects apparent within one day of initiating therapy. Patients who experience exercise-induced symptoms should take their dose at least two hours before exercise, although the standard once-daily evening regimen also provides protection during daytime physical activity due to the sustained pharmacodynamic effect of the drug.
The story of montelukast illustrates important lessons about drug development and postmarketing surveillance. The drug was developed based on a clear understanding of leukotriene pathophysiology and was brought to market after demonstrating efficacy and safety in well-designed clinical trials. Its widespread use over more than two decades has provided extensive real-world data on its effectiveness and safety, including rare adverse effects that were not fully appreciated during preapproval trials. The identification of neuropsychiatric concerns through postmarketing surveillance systems and the subsequent regulatory actions demonstrate the importance of ongoing monitoring of medications after they enter the market. This pharmacovigilance system has allowed for appropriate risk mitigation while preserving access to a beneficial medication for patients who can use it safely. For healthcare professionals, the montelukast experience shows the importance of individualized treatment decisions. A boxed warning does not mean that a medication should never be used, but rather that its use requires careful consideration and ongoing monitoring. For many patients with asthma who have achieved good control with montelukast without adverse effects, the benefits of continued therapy outweigh the low absolute risk of neuropsychiatric events.
In summary, montelukast remains a valuable tool for asthma and allergic rhinitis. Its once-daily oral dosing, favorable safety profile relative to many alternatives, affordability in generic form, and availability in child-friendly formulations make it an attractive option for many patients. While the neuropsychiatric safety concerns highlighted by regulatory authorities warrant caution and appropriate monitoring, they do not negate the significant therapeutic benefits that montelukast provides for properly selected and monitored patients. When used appropriately, montelukast can help patients with asthma and allergies breathe easier, sleep better, and live fuller, more active lives free from the limitations imposed by uncontrolled respiratory disease.
