Singulair, known generically as montelukast, is a medication widely used to treat asthma and allergic rhinitis. It belongs to a class called leukotriene receptor antagonists, which work by blocking substances in the body called leukotrienes. These leukotrienes cause inflammation, swelling, and tightening of the airways, leading to asthma symptoms or allergy reactions.
Doctors often prescribe Singulair to prevent asthma attacks and relieve symptoms such as wheezing, shortness of breath, and nasal congestion. It is taken orally, usually once a day, and is suitable for both adults and children. The convenience of a daily pill makes it a popular choice for long-term management of respiratory and allergy issues. Singulair has been shown to improve overall quality of life for many patients, allowing them to engage in daily activities without the constant worry of asthma symptoms or allergy flare-ups. This aspect is particularly beneficial for children, as it can help them participate fully in school and recreational activities.
Leukotrienes are chemicals your body releases in response to allergens or irritants. They cause inflammation and constriction in the lungs and nasal passages. Singulair blocks the receptors that leukotrienes bind to, reducing inflammation and preventing airway tightening.
This action helps improve breathing, reduce asthma flare-ups, and ease allergy symptoms. Unlike quick-relief inhalers, Singulair is not for immediate symptom relief but for ongoing control and prevention. It is important to note that while Singulair is effective for many, it may take several days to see the full benefits of the medication, as it works gradually to reduce inflammation and improve lung function over time. This makes consistent daily use crucial for optimal results.
Singulair is typically recommended for people with:
Chronic asthma needs daily control
Seasonal or perennial allergic rhinitis (hay fever)
Exercise-induced bronchoconstriction
It is important to follow your healthcare provider’s instructions and not use Singulair as a substitute for emergency asthma treatments. Patients should discuss their complete medical history with their healthcare provider, as certain conditions or medications may affect how Singulair works or increase the risk of side effects. For instance, individuals with liver problems or those taking other medications that affect liver enzymes may require closer monitoring while on Singulair. Understanding these nuances can help ensure that patients receive the most effective and safe treatment for their respiratory conditions.
Like any medication, Singulair can cause side effects. Most people tolerate it well, but some may experience mild to moderate symptoms. Knowing what to expect and how to handle side effects can make treatment smoother.
Headache
Stomach pain or indigestion
Dizziness
Fatigue
Sore throat
Neuropsychiatric side effects
Fever
Cough or nasal congestion
These symptoms often improve as your body adjusts to the medication. Drinking plenty of water, eating balanced meals, and resting can help ease these effects.
If side effects persist or interfere with daily life, consult your healthcare provider. They may adjust your dosage or suggest alternative treatments. Never stop taking Singulair without medical advice, as this can worsen asthma or allergy symptoms.

Important Mental Health ConsiderationsOne of the more serious concerns with Singulair involves potential neuropsychiatric side effects. These are less common but important to recognize.
Changes in mood, such as anxiety or depression
Sleep disturbances, including insomnia or vivid dreams
Agitation or irritability
Suicidal thoughts or behavior
Patients and caregivers should monitor for any unusual changes in behavior or mood, especially during the first few months of treatment. If you notice these symptoms, contact your healthcare provider immediately.
Do not stop taking Singulair abruptly without consulting a doctor. Instead, reach out to a medical professional promptly. Telehealth services like Doctronic.ai can provide quick evaluations and guidance to help you safely manage these symptoms.
Early intervention can prevent complications and ensure you receive the right support.
Always take Singulair exactly as prescribed. Do not skip doses or take extra pills to compensate for missed ones. Consistency is key to controlling asthma and allergies effectively.
Singulair can interact with other drugs. Make sure your healthcare provider knows about all medications, supplements, and herbal products you use. This helps avoid adverse interactions.
Maintaining a symptom diary can help you and your doctor assess how well Singulair is working. Note any side effects and changes in your asthma or allergy symptoms.
Schedule follow-up visits to review your treatment plan. Your doctor may adjust your medication based on your progress and any side effects you experience.
While Singulair is generally safe, certain situations require immediate attention.
Severe allergic reactions such as rash, swelling, or difficulty breathing
Sudden worsening of asthma symptoms
Signs of liver problems, like yellowing skin or eyes
If you experience any of these, seek emergency care right away.
