What is Singulair?

Singulair, with the active compound Montelukast, is classified as a leukotriene receptor antagonist. It is a prescription medication available as a pill in several dosages: 4mg, 5mg, and 10mg. Montelukast was developed to target specific inflammatory pathways involved in respiratory conditions. As Montelukast is available generically, Singulair is the original branded medication containing this active substance. Generic versions of Montelukast are widely available, offering a more cost-effective alternative for patients and are marketed under brand names such as various other Montelukast products.

How Montelukast Works

Montelukast works by selectively blocking the action of leukotrienes on specific receptors in the body. Leukotrienes are inflammatory molecules naturally produced by the body, particularly in response to allergens. When leukotrienes bind to their receptors (specifically the cysteinyl leukotriene receptor type 1, or CysLT1), they trigger a cascade of inflammatory and constrictive responses in the airways. These responses include airway inflammation, smooth muscle contraction (leading to bronchoconstriction), and increased mucus production.

By inhibiting leukotrienes from binding to the CysLT1 receptor, Montelukast effectively counteracts these effects. It helps to reduce airway inflammation, ease airway muscle tightening, and decrease swelling in the airways. This mechanism leads to improved symptoms for individuals with asthma and allergic rhinitis, such as easier breathing, reduced wheezing, and less nasal congestion. The onset of its therapeutic effect is generally within a day, and it provides sustained control over symptoms as long as the medication is taken regularly.

Conditions Treated with Montelukast

Montelukast is approved for several respiratory conditions, providing relief from inflammation and airway narrowing.

• Asthma: Montelukast is used as a controller medication for mild to moderate persistent asthma in adults and children. It helps to prevent asthma symptoms, reduce the frequency and severity of asthma attacks, and improve overall lung function by reducing airway inflammation and constriction. It is not typically used as a rescue inhaler for acute asthma attacks.

• Allergic Rhinitis (Seasonal): For individuals suffering from seasonal allergies, Montelukast can effectively alleviate symptoms such as sneezing, runny nose, nasal congestion, and itchy nose or throat. It targets the inflammatory pathways triggered by seasonal allergens.

• Allergic Rhinitis (Perennial): Similar to seasonal allergies, Montelukast also helps manage the symptoms of perennial allergic rhinitis, which occurs year-round due to allergens like dust mites or pet dander. It reduces inflammation and congestion in the nasal passages.

• Exercise-Induced Bronchoconstriction (EIB): Montelukast can be used to prevent the narrowing of airways that occurs in some individuals during or after exercise. It is taken prior to physical activity to reduce the likelihood and severity of exercise-induced breathing difficulties.

Is Montelukast the Right Medication for You?

Montelukast is a valuable treatment option for adults and children experiencing persistent asthma, seasonal or perennial allergic rhinitis, or exercise-induced bronchoconstriction. It is particularly beneficial for individuals who prefer an oral medication over inhaled corticosteroids or other asthma controllers, or for those whose symptoms are not adequately controlled by other treatments. Patients experiencing significant nasal congestion, sneezing, and itching associated with allergies often find considerable relief with Montelukast. It is also an option for athletes or active individuals concerned about exercise-induced breathing difficulties.

However, Montelukast is not suitable for everyone. It is not a rescue medication for acute asthma attacks and should not be used to treat sudden breathing emergencies. Individuals with a known hypersensitivity to Montelukast or any of its inactive ingredients should avoid it. Certain psychiatric side effects, though rare, have been reported, so patients with a history of significant mood disorders or behavioural changes should discuss this with their healthcare provider. It is crucial to have a thorough discussion with a healthcare professional to determine if Montelukast aligns with your specific medical history and treatment needs.

Use: Dosing, Missed Dose, Overdose

General dosing guidelines for Montelukast are as follows, but specific instructions should always be followed as prescribed by a healthcare professional.

• Adults and Adolescents (15 years and older) for Asthma and Allergic Rhinitis: The typical dose is one 10mg pill once daily in the evening.
• Children (6 to 14 years) for Asthma and Allergic Rhinitis: The typical dose is one 5mg pill once daily in the evening.
• Children (2 to 5 years) for Asthma and Allergic Rhinitis: The typical dose is one 4mg pill once daily in the evening.
• Exercise-Induced Bronchoconstriction (Adults and Adolescents 15 years and older): Take one 10mg pill at least 2 hours before exercise. Do not take an additional dose on the same day and do not take it daily for this indication. Consult your healthcare provider for specific usage instructions.

Missed Dose: If you miss a dose, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.

Overdose: In case of a suspected overdose, seek immediate medical attention. Symptoms of Montelukast overdose are not well-defined in publicly available data but may include gastrointestinal upset or increased adverse effects. Contact your local poison control centre or emergency services for guidance.

Practical Precautions:

• Montelukast can be taken with or without food.
• Avoid alcohol while taking Montelukast, as it could potentially increase the risk of side effects or interact with the medication's effects.
• While Montelukast itself typically does not cause significant drowsiness, it is advisable to avoid operating machinery or driving until you know how it affects you if you experience any dizziness or impaired reactions.

Safety Information

⚠️ Who Should Not Take Montelukast

Montelukast is contraindicated in individuals with a known hypersensitivity to Montelukast or any of its excipients. Patients who have experienced allergic reactions to Montelukast in the past should not take it. Specific warnings apply to certain patient groups related to potential neuropsychiatric effects, and patients with a history of such effects should exercise caution and consult a healthcare provider.

Common Side Effects

The most common side effects associated with Montelukast are generally mild and transient. These can include:

• Headache
• Abdominal pain
• Diarrhea
• Nausea
• Vomiting
• Rash
• Elevated liver enzymes (which are usually detected through blood tests and may not cause noticeable symptoms)

These side effects often resolve on their own as your body adjusts to the medication. If they persist or become bothersome, consult your healthcare provider.

Serious Side Effects (Seek Immediate Medical Help)

Although rare, serious side effects can occur. Seek immediate medical attention if you experience any of the following:

• Neuropsychiatric Events: These can include agitation, aggressive behaviour, anxiety, depression, hallucinations, insomnia, memory impairment, suicidal thoughts or behaviour. Report any unusual changes in mood or behaviour promptly.
• Allergic Reactions: Signs of a severe allergic reaction (anaphylaxis) include swelling of the face, lips, tongue, or throat; difficulty breathing; hives; and severe dizziness.
• Churg-Strauss Syndrome: In very rare cases, patients taking Montelukast can develop a condition called Churg-Strauss syndrome, which causes inflammation of blood vessels. Symptoms can include fever, rash, and a condition called eosinophilia.

Drug & Food Interactions

• Phenobarbital: The interaction of Montelukast with Phenobarbital has been studied, resulting in decreased AUC (area under the curve) of Montelukast. However, clinical significance is not well-established.
• Certain CYP1A2 Inhibitors: Medications that inhibit CYP1A2 enzymes might increase Montelukast levels, though this is not typically considered a significant interaction.
• Grapefruit Juice: While specific interactions between Montelukast and grapefruit juice are not widely documented as clinically significant, it is generally advisable to discuss any regular consumption of grapefruit products with your doctor or pharmacist, as grapefruit can affect the metabolism of many medications.
• Food: Montelukast can be taken with or without food, so no dietary restrictions are necessary regarding meal times.

Off-Label and Investigational Uses of Montelukast

While Montelukast is primarily indicated for asthma, allergic rhinitis, and exercise-induced bronchoconstriction, clinical studies and practice have explored its use in other conditions.

• Urticaria: Montelukast has been investigated for its potential role in managing chronic urticaria (hives) that are refractory to standard antihistamine treatment. Some research suggests it may reduce the frequency and severity of lesions in certain individuals by further reducing inflammation pathways. However, this use is not officially approved by regulatory bodies.

• Nasal Polyps: Some evidence suggests Montelukast might be helpful as adjunctive therapy in reducing the size of nasal polyps, especially when associated with asthma. This application is considered investigational and requires further research to establish definitive efficacy and safety.

It is important to note that these off-label and investigational uses have not undergone the same rigorous approval process by regulatory authorities as the approved indications. Efficacy and safety in these contexts may not be as well-established, and treatment should strictly be under the guidance of a qualified healthcare provider who can assess the individual risks and benefits.

Storage & Handling

Montelukast pills should be stored at room temperature, typically between 20°C to 25°C (68°F to 77°F). They should be protected from excessive heat, light, and moisture. Keep the medication in its original container to protect it from light and humidity. It is crucial to store Montelukast out of the reach and sight of children. Always check the expiry date on the packaging and do not use the medication after this date. Dispose of any expired or unused medication safely according to local guidelines for pharmaceutical waste, often by returning it to a pharmacy or designated collection point.
