Drug Class: Leukotriene Receptor Antagonist - LTRA | Form: Film-Coated Tablets (Oral) | Prescription Status: Prescription Only (Rx) - DRAP Registered
What is Myteka Tablets 10mg?
Myteka Tablets 10mg contain Montelukast sodium - a leukotriene receptor antagonist or LTRA (لیوکوٹرین بلاک کرنے والی دوا) used in adults and adolescents aged 15 years and older for the long-term management of asthma (دمہ), prevention of exercise-induced bronchoconstriction (ورزش سے سانس کی نالی کا تنگ ہونا), and treatment of seasonal and perennial allergic rhinitis (موسمی اور سال بھر رہنے والی ناک کی الرجی). When the airways or nasal passages are exposed to allergens - such as pollen, dust mites, pet dander, smoke, or cold air - the immune system releases inflammatory chemicals called leukotrienes (لیوکوٹرینز) that cause the airways to narrow, swell, and produce excess mucus. Montelukast blocks the receptors these chemicals attach to - preventing the inflammatory process that causes asthma and allergy symptoms. The 10mg film-coated tablet is the standard adult dose - providing the full therapeutic level of leukotriene receptor blockade for adults and adolescents 15 years and older. Myteka 10mg is a controller medicine taken once daily - not a rescue inhaler - and requires a valid prescription.
What is Myteka 10mg Used For?
Myteka Tablets 10mg is indicated for the following conditions in adults and adolescents aged 15 years and older:
Chronic Asthma - Long-Term Management (دمہ کا طویل مدتی علاج) - daily prevention and control of asthma symptoms including recurrent wheezing (سانس میں سیٹی کی آواز), shortness of breath (سانس پھولنا), chest tightness (سینے میں جکڑن), and coughing (کھانسی) - used as monotherapy or alongside inhaled corticosteroids as add-on therapy
Exercise-Induced Bronchoconstriction - EIB (ورزش سے سانس کی نالی کا تنگ ہونا) - prevents the airway narrowing triggered by physical exercise - taken at least 2 hours before planned exercise when used specifically for this purpose
Seasonal Allergic Rhinitis (موسمی الرجی) - treatment of symptoms caused by seasonal allergens such as pollen - including sneezing (چھینکیں), runny nose (بہتی ناک), nasal congestion (بند ناک), and itchy, watery eyes (آنکھوں میں خارش اور پانی)
Perennial Allergic Rhinitis (سال بھر رہنے والی الرجی) - treatment of year-round allergy symptoms caused by persistent indoor allergens such as house dust mites, mould, and pet dander
Aspirin-Sensitive Asthma (اسپرین سے حساس دمہ) - Montelukast is particularly useful in patients whose asthma or rhinitis is triggered or worsened by aspirin or NSAIDs - as leukotriene overproduction is a key feature of this condition
How Does Myteka 10mg Work?
Myteka contains Montelukast sodium - a selective, orally active leukotriene receptor antagonist that prevents airway inflammation at the molecular level.
When the airways or nasal passages encounter an allergen or irritant, specialised immune cells - particularly mast cells and eosinophils - release cysteinyl leukotrienes: LTC4, LTD4, and LTE4 (سسٹینائل لیوکوٹرینز). These inflammatory mediators bind to CysLT1 receptors on the smooth muscle and mucosal cells lining the airways and nose - triggering three key responses that produce asthma and allergy symptoms: bronchoconstriction (سانس کی نالی کا تنگ ہونا), increased mucus secretion (بلغم کا زیادہ بننا), and mucosal oedema and swelling (سوزش).
Montelukast selectively and competitively occupies the CysLT1 receptor - blocking leukotrienes from binding and initiating this inflammatory cascade. The result is reduced airway and nasal inflammation, prevention of bronchoconstriction, decreased mucus production, and relief from congestion and allergy symptoms.
At 10mg - the standard adult dose - Montelukast achieves the plasma concentration required for near-complete CysLT1 receptor occupancy in adults - providing consistent, sustained leukotriene pathway blockade when taken daily. Its once-daily dosing and oral administration make it a particularly convenient long-term controller for adults managing chronic asthma or persistent allergic disease.
Dosage and Administration
Myteka 10mg must be taken exactly as prescribed by your doctor. Do not change your dose or stop treatment without medical advice (ڈاکٹر کے مشورے کے بغیر خوراک تبدیل نہ کریں یا دوا بند نہ کریں).

- If used for both asthma and allergic rhinitis - one tablet covers both conditions - do not take an extra tablet for the rhinitis
- Never use Myteka as a rescue medicine during an acute asthma attack - use your prescribed rescue inhaler (such as Salbutamol) for sudden breathing difficulty
- If a dose is missed (خوراک بھول جائیں) - take it as soon as remembered. If it is almost time for the next dose, skip the missed one. Never take a double dose.

Who Should NOT Use Myteka 10mg?
Do not use Myteka if you (استعمال نہ کریں اگر):
- Are allergic to Montelukast or any other ingredient in the tablet (الرجی ہو)
- Are under 15 years of age - use the age-appropriate 4mg (6 months to 5 years) or 5mg (6 to 14 years) formulation instead
Tell your doctor before use if (ڈاکٹر کو بتائیں اگر):
- You have liver problems (جگر کی بیماری) - Montelukast is primarily metabolised by the liver - dose adjustment may be needed in severe liver disease
- You have phenylketonuria (فینائل کیٹونیوریا) - the 10mg film-coated tablet does not contain aspartame - but always check the label of the specific pack dispensed
- You have a known aspirin or NSAID sensitivity (اسپرین سے الرجی) - Montelukast is particularly useful but may not fully prevent all reactions - avoid known triggers
- You are pregnant (حاملہ) or breastfeeding (دودھ پلانے والی ماں) - limited data is available - your doctor will assess the risk-benefit balance for your situation
- You experience any change in mood, behaviour, or sleep after starting Myteka - neuropsychiatric effects must be reported to your doctor immediately
Side Effects
Not everyone will experience side effects. Myteka 10mg is generally well tolerated in adults and adolescents.
Common Side Effects (عام ضمنی اثرات):

Frequently Asked Questions
What is Myteka 10mg used for?
Myteka 10mg contains Montelukast - a leukotriene receptor antagonist used in adults and adolescents aged 15 years and older to manage chronic asthma (دمہ), prevent exercise-induced bronchoconstriction (ورزش سے سانس کی نالی کا تنگ ہونا), and treat seasonal and year-round allergic rhinitis (ناک کی الرجی). It works by blocking CysLT1 receptors - preventing leukotriene-driven airway inflammation and narrowing. A single daily evening dose covers both asthma and rhinitis when both conditions are present.
Can Myteka 10mg cause depression or suicidal thoughts?
Yes - this is the most important safety warning for Montelukast. Neuropsychiatric side effects - including anxiety, depression, insomnia, agitation, and in rare cases suicidal thoughts - have been reported in patients of all ages taking Montelukast, including adults. These effects are uncommon but serious. If you or a family member notices any mood changes, unusual behaviour, sleep disturbances, or thoughts of self-harm after starting Myteka, stop the medicine immediately and seek urgent medical attention (فوری طور پر ڈاکٹر سے رابطہ کریں). These effects are reversible when Montelukast is stopped.
Does Myteka 10mg replace an inhaler for asthma?
No - Myteka 10mg is not a substitute for an inhaled corticosteroid or a rescue bronchodilator. It is an add-on oral controller used alongside inhaled therapy in adults with asthma not fully controlled by an inhaled corticosteroid alone - or as monotherapy in mild persistent asthma under specialist guidance. For acute asthma attacks or sudden breathlessness, always use your prescribed rescue inhaler (such as Salbutamol - سالبوٹامول). Never reduce or stop your inhaled medicines without your doctor's advice.
Can Myteka 10mg be used for both asthma and allergic rhinitis at the same time?
Yes - one of the practical advantages of Montelukast is that a single 10mg tablet taken once daily in the evening is effective for both conditions simultaneously. Patients with comorbid asthma and allergic rhinitis (دمہ اور ناک کی الرجی دونوں) do not need to take separate doses for each condition - one tablet covers both. This makes Myteka particularly convenient for adults managing both conditions year-round.
All three Myteka strengths contain the same active ingredient - Montelukast - and work through exactly the same mechanism. The difference is the dose required for different age groups and body weights. The 4mg chewable tablet is for young children aged 6 months to 5 years. The 5mg chewable tablet is for children aged 6 to 14 years. The 10mg film-coated tablet is the full adult dose for adolescents and adults aged 15 years and older - providing the plasma concentration required for complete CysLT1 receptor blockade in adults. Never give the adult 10mg tablet to younger children without specific medical advice.
