How this medicine works
The DailyMed label describes montelukast as an orally active leukotriene receptor antagonist that binds the CysLT1 receptor with high affinity and selectivity. This mechanism helps explain drug class and label boundaries; it cannot judge an individual's wheeze, allergy symptoms, acute risk, product choice or use.

A medicine may use different brand names across markets. Keep the market, brand, generic name, dosage form and route together; one matching field does not prove that two packs are the same or interchangeable.

What this page can show
This is a source-traceable public record. It helps you read the product identity and its listed source documents; each market still needs its own current record check.
What to bring to the next conversation
Bring the actual pack, the label or prescription, and a complete medicine list when you speak with a pharmacist or clinician.

PRODUCT PRESENTATION IDENTITY
Strength, pack and device identity
Package strength is not an individual dose. These fields help identify the exact labelled product; they do not calculate how much, how often, a missed-use action, splitting, switching or conversion.
Film-coated tablets, chewables and oral granules are not a self-conversion by tablet count, sachet count or milligrams. Read the exact form, NDC and pack together; this page does not decide individual use or switching.

First match the market, dosage form and labelled amount on the pack in hand. The number of tablets, sachets or devices in a pack is not a personal dose or schedule.

PUBLIC LABEL IMAGE
Appearance and package-text clues
This dated or historical public-label image is for checking the brand, generic-name, strength and dosage-form clues only. It does not authenticate a product or establish originator status, a current label, current packaging, target-market approval or sale eligibility.
Open the public label source ↗LABEL READING · NOT A PRESCRIPTION
SINGULAIR label reading: tablets, chewables and oral granules are distinct product forms
Reading level: drug-specific label reading. This record has been expanded around its dosage form or a higher-risk reading question; the current target-market label and professional review still apply.
This module uses the U.S. DailyMed public label to distinguish SINGULAIR, montelukast sodium, film-coated tablets, chewable tablets, oral granules and target market. It does not provide individual dosing, start/stop, acute-symptom management or a combination plan with another respiratory/allergy medicine.
- Check SINGULAIR, montelukast sodium, the exact form, stated strength per unit and target market together. A shared non-proprietary name does not make film-coated tablets, chewables and granules self-convertible or substitutable by tablet count, sachet count or experience.
- The label includes a neuropsychiatric-events warning. With a new or concerning change in mood, behaviour, sleep or thinking, promptly contact a professional through local medical channels; do not self-stop, restart, increase or change to another medicine from a webpage.
- The label also says this product is not for reversal of acute bronchospasm. Sudden or worsening breathing difficulty should not be managed by self-escalation, waiting for a webpage or borrowing another person's medicine; use local emergency and care-team guidance.
- Package images, a name and “allergy/asthma” wording only help locate a label. They cannot authenticate a product, establish current approval or prove interchangeability with another allergy, inhaled or rescue product. Ask a pharmacist to review the complete medicine list with every addition, stop or change.

Check safety information in the right market
Start with the public label or product record linked to this dossier, then use the official safety routes below for the market that applies to the medicine in hand.
Match five details before using a safety record
- Brand and generic nameBoth must match the medicine named by the record.
- Dosage form and strengthTablet, capsule, injection, inhaler, patch and eye drop are not interchangeable.
- Market and notice dateA record applies only to the country or region and date it names.
- Lot, pack and manufacturerRecord these only when the official notice specifically names them.
- Current product informationA historical record may have been superseded by the current label.
This checklist only helps organise the right question. It does not create a personal conclusion about stopping, switching, dose, combination or suitability.

- FDA Drug Safety Communication: Boxed Warning for mental-health effects with montelukast (Singulair)2020-03-04 · On 2020-03-04, FDA issued a Drug Safety Communication saying that, after reviewing available information, it required a Boxed Warning in prescribing information for montelukast (Singulair and generics) about mental-health effects and a new patient Medication Guide; the communication also describes U.S. benefit-risk considerations for allergic rhinitis. This is a dated U.S. regulatory communication, not a conclusion about any person’s symptoms, indication or current treatment.

Six checks for this medicine pack
Use this card to organise questions about Singulair (montelukast). Keep the exact pack, its current label and the full medicine list together.
Identify the exact product
Singulair is the brand in this record and montelukast is the active-ingredient name. Check both with the dosage form (Film-coated tablets, chewable tablets and oral granules (as documented in this dossier)) and the market on the actual pack.
Read the labelled strength in context
mg, mcg, mg/mL or a percentage describes the labelled amount in one tablet, capsule, measured volume, spray or other unit. It is not an answer to how many units a person should take.
Check before splitting or opening
Before splitting, crushing, chewing or opening anything, find an explicit instruction for this exact product in its current label and ask a pharmacist. A score line or a previous pack is not enough by itself.
Put every product on one list
Include prescriptions, over-the-counter products, eye drops, creams, vitamins, minerals, herbs and supplements. A pharmacist or prescriber needs the whole list before any combination, alternation, switch or stop is considered.
Ask a specific pharmacogenetics question
Ask which medicine, which gene and what clinical decision a result could change. A gene–drug association does not mean broad genetic testing is needed for everyone and must not be used to change treatment without professional review.
Know when to seek urgent help
For a suspected overdose, a severe allergic reaction, fainting or difficulty breathing, use the local emergency or poison-information service now. Do not wait for a website reply or alter several medicines to test what caused it.
This card does not calculate a dose, decide whether medicines can be combined, or replace a clinician or pharmacist. Market-specific current labels and the person's full context still need review.
HOW IT WORKS · NOT A TREATMENT PLAN
How montelukast works: it blocks the CysLT1 leukotriene receptor but does not replace acute breathing care
- “Leukotriene receptor antagonist” describes an action pathway. It does not automatically attribute every cough, wheeze, chest tightness, congestion or rash to one cause, and it cannot replace diagnosis.
- Shared allergy or respiratory-use wording does not make montelukast self-combinable, substitutable or convertible by milligrams with an antihistamine, inhaled product, rescue medicine or another form.
- Mechanism cannot turn a non-acute maintenance product into a self-management plan for sudden or worsening breathing difficulty. With acute symptoms, concerning behaviour/mood changes or a need to change use, use local medical pathways and bring the complete medicine list.

RECORD FAQ
Record questions
Does a label archive represent current product information?
Not automatically. The archive locates a source; each point needs verification against the target market’s current official label.
Why are price and originator/generic conclusions not shown?
Those conclusions require separately complete and human-reviewed product, dosage-form, strength, pack, market, date and primary-record fields; one label file is insufficient.
