Drug Class: Leukotriene Receptor Antagonist (LTRA) | Form: Oral Granules Sachet | Manufacturer: Bosch Pharmaceuticals | Prescription Status: Prescription Only (Rx) — DRAP Registered
What is Beasy Sachet 4mg?
Beasy Sachet 4mg is an oral granules formulation manufactured by Bosch Pharmaceuticals — containing Montelukast Sodium 4mg in a convenient sachet designed specifically for young children who cannot swallow tablets. Montelukast is a leukotriene receptor antagonist — a medicine that blocks leukotrienes, the powerful inflammatory chemicals released during allergic reactions that cause airway narrowing, mucus production, and nasal congestion. Unlike bronchodilator inhalers that provide immediate but short-lived relief, Montelukast works as a daily preventive medicine — taken once every evening to maintain long-term control of asthma symptoms (دمہ) and allergic rhinitis (ناک کی الرجی) in children. The sachet formulation makes it easy to mix into soft food or a small amount of liquid — improving medication compliance in young children who find inhalers or tablets difficult to use. Beasy Sachet 4mg is approved for children aged 6 months to 5 years and must always be used under a doctor's supervision.
What is Beasy Sachet 4mg Used For?
- Chronic asthma prevention — daily long-term control of asthma symptoms in children aged 6 months to 5 years (دمہ کی روک تھام)
- Exercise-induced bronchoconstriction — preventing airway narrowing triggered by physical activity or exercise in asthmatic children (ورزش سے دمہ)
- Seasonal allergic rhinitis — relieving sneezing, runny nose, nasal itching, and congestion caused by pollen and seasonal allergens (موسمی ناک کی الرجی)
- Perennial allergic rhinitis — year-round management of nasal allergy symptoms caused by dust mites, pet dander, and other persistent allergens (سالانہ ناک کی الرجی)
- Allergic asthma — management of asthma triggered by allergen exposure in atopic children
- It is not a rescue medicine — Beasy Sachet does not relieve sudden acute asthma attacks; a fast-acting bronchodilator must always be available for acute attacks
How Does Beasy Sachet 4mg Work?
Leukotriene Receptor Blockade: When the airways or nasal passages are exposed to an allergen — such as pollen, dust, or pet dander — specialised immune cells called mast cells and eosinophils release powerful inflammatory chemicals called leukotrienes (particularly LTC4, LTD4, and LTE4). Leukotrienes bind to cysteinyl leukotriene receptors on airway smooth muscle cells, mucus-secreting cells, and blood vessel walls — triggering three harmful effects simultaneously: bronchoconstriction (airway narrowing making breathing difficult), increased mucus production (congestion and blocked airways), and mucosal oedema (swelling of the airway lining). In allergic rhinitis, the same leukotrienes cause nasal congestion, sneezing, and runny nose.
Montelukast selectively and competitively blocks the cysteinyl leukotriene type 1 (CysLT1) receptor — preventing leukotrienes from binding and triggering these inflammatory responses. By blocking this receptor consistently with once-daily dosing, Montelukast reduces the frequency and severity of asthma symptoms, decreases airway hypersensitivity, reduces mucus production, and relieves nasal allergy symptoms — all without the sedation associated with antihistamines.
Anti-inflammatory Effect: Beyond receptor blockade, Montelukast reduces the overall eosinophilic airway inflammation that underlies both allergic asthma and allergic rhinitis — providing a disease-modifying anti-inflammatory benefit alongside its symptom-control effect. This makes it particularly valuable as a long-term preventive medicine in children with concurrent asthma and allergic rhinitis — two conditions that frequently occur together.
Dosage and Administration
⚠️ Always give exactly as prescribed by your child's doctor. Never exceed the prescribed dose. Beasy Sachet is a once-daily preventive medicine — it must be given every evening consistently for effective long-term asthma and allergy control.
| Age Group | Dose | Frequency | Time of Day |
|---|---|---|---|
| 6 months to 5 years | 1 sachet (4mg) | Once daily | Evening |
| Exercise-induced bronchoconstriction | 1 sachet (4mg) | At least 2 hours before exercise | As needed — not more than once daily |
Critical Dosing Rules:
- Beasy Sachet 4mg is a preventive medicine — it must be given every day consistently even when the child has no symptoms; stopping during symptom-free periods removes protection and allows asthma to return
- Never give Beasy Sachet during an acute asthma attack — it does not work quickly enough to relieve sudden bronchospasm; always use the child's prescribed fast-acting bronchodilator inhaler for acute attacks
- Evening dosing is preferred for asthma control — asthma symptoms are typically worse at night and early morning; evening Montelukast provides peak protection during this vulnerable period
- For exercise-induced bronchoconstriction, give at least 2 hours before planned physical activity — if the child is already taking daily Beasy Sachet, do not give an additional dose before exercise
- The 4mg sachet is approved for children aged 6 months to 5 years — children aged 6 to 14 years require the 5mg chewable tablet formulation
How to Give:
- Open the sachet immediately before use — do not store opened sachets
- Mix the entire contents of the sachet with one teaspoon of soft food — such as yoghurt, mashed potato, rice, or apple puree — or a small amount of breast milk or infant formula
- Give immediately after mixing — do not store the mixture or dissolve in liquid for later use
- Do not mix with any liquid other than breast milk or infant formula
- Ensure the child takes the full dose — do not give partial sachets
- If a dose is missed, give it as soon as remembered the same evening — skip if it is the next day; never double the dose
Active Ingredients
| Ingredient | Strength per Sachet |
|---|---|
| Montelukast Sodium | 4mg |
Who Should NOT Take Beasy Sachet 4mg?
Do not give if the child:
- Is allergic to Montelukast or any ingredient in the sachet
- Is under 6 months of age — not approved below this age
- Has phenylketonuria — if the sachet contains Aspartame as a sweetener
Always consult your doctor before giving Beasy Sachet if the child has:
- Liver disease — Montelukast is metabolised in the liver; use with caution in significant hepatic impairment
- A history of psychiatric or behavioural symptoms — Montelukast carries an FDA and regulatory warning for neuropsychiatric side effects including agitation, aggression, and sleep disturbances in children
- Aspirin-sensitive asthma — inform doctor; Montelukast does not provide complete protection against aspirin-triggered asthma
- Is taking phenobarbital, rifampicin, or other CYP enzyme inducers — may reduce Montelukast effectiveness
- Is on any other asthma or allergy medicines — your doctor will advise on appropriate combination therapy
Side Effects
Common Side Effects:
- Mild stomach pain or nausea — usually temporary and mild
- Diarrhoea — mild and self-limiting
- Thirst or increased fluid intake
- Mild headache
- Fever — common in young children; monitor temperature
- Upper respiratory tract infection symptoms — runny nose or mild cold-like symptoms
- Skin rash — mild and usually temporary; report to doctor if worsening
Serious Side Effects — Stop Giving and Seek Medical Help Immediately:
- Neuropsychiatric effects — agitation, aggression, restlessness, abnormal dreams, nightmares, sleep disturbances, hallucinations, depression, or unusual behaviour changes — the FDA and global regulatory agencies have issued specific warnings about these effects with Montelukast in children; stop immediately and inform your doctor (والدین اس کا خاص خیال رکھیں)
- Severe allergic reaction — swelling of face, lips, tongue or throat, difficulty breathing, widespread rash or hives — life-threatening emergency requiring immediate hospital care (یہ طبی ہنگامی صورتحال ہے)
- Severe skin reactions — Churg-Strauss syndrome (eosinophilic granulomatosis with polyangiitis) — rare but serious systemic vasculitis reported with leukotriene antagonists; symptoms include widespread rash, worsening respiratory symptoms, and systemic illness; stop immediately
- Eosinophilic pneumonia — worsening breathlessness, fever, and cough — rare; stop and seek immediate medical evaluation
- Severe liver toxicity — yellowing of skin or eyes (یرقان), dark urine, extreme fatigue — rare but reported; stop immediately and seek medical attention
- Suicidal thoughts — extremely rare but reported in post-marketing surveillance; seek immediate psychiatric help if observed
Drug Interactions
| Medicine / Substance | Possible Interaction |
|---|---|
| Rifampicin (antibiotic) | Significantly reduces Montelukast blood levels through CYP enzyme induction — may reduce its effectiveness; inform your doctor |
| Phenobarbital / Phenytoin (antiepileptics) | Reduce Montelukast blood levels through CYP3A4 induction — monitor asthma control closely if these medicines are being used |
| Gemfibrozil | Increases Montelukast blood levels significantly — monitor for increased side effects |
| Inhaled corticosteroids (e.g., Budesonide, Fluticasone) | Commonly used together — Montelukast complements inhaled steroid therapy; no harmful interaction; combination improves asthma control |
| Short-acting bronchodilators (e.g., Salbutamol) | Used together safely — Montelukast is the daily preventive medicine while Salbutamol remains the rescue medicine for acute attacks |
| Aspirin / NSAIDs | Children with aspirin-sensitive asthma should avoid NSAIDs regardless of Montelukast use — Montelukast does not fully protect against NSAID-triggered bronchospasm |
| Warfarin | Montelukast may slightly increase Warfarin effect — monitor INR if both medicines are used |

Frequently Asked Questions (FAQs)
Q: Can Beasy Sachet 4mg be used during an acute asthma attack? No — Beasy Sachet is a daily preventive medicine that takes time to work; it cannot relieve sudden bronchospasm; always keep the child's prescribed fast-acting bronchodilator inhaler available at all times for acute asthma attacks.
Q: Why has my child become more agitated or had unusual nightmares since starting Beasy Sachet? Montelukast carries a regulatory warning for neuropsychiatric side effects in children including agitation, nightmares, and behavioural changes — stop giving the sachet and consult your doctor immediately if any unusual behavioural or mood changes are observed.
Q: Does Beasy Sachet 4mg need to be given every day even when my child has no symptoms? Yes — consistent daily dosing is essential for effective long-term asthma control; stopping during symptom-free periods removes ongoing protection and allows inflammation to return; continue until your doctor advises otherwise.
Q: Can Beasy Sachet granules be mixed with any food or drink? Mix only with one teaspoon of soft food such as yoghurt, mashed potato, or apple puree — or a small amount of breast milk or infant formula; never dissolve in liquid or store the mixture; give immediately after mixing.
