Montebasto (Montelukast) in Kenya

Overview

Montebasto is a leukotriene receptor antagonist containing montelukast, used for asthma maintenance (prevention of exercise-induced bronchospasm, chronic asthma) and allergic rhinitis (seasonal/perennial). It reduces inflammation by blocking leukotrienes, improving breathing and reducing allergy symptoms. Available as 10mg tablets in Kenya, it requires prescription for asthma but may be OTC for allergies.

Composition

• Active Ingredient: Montelukast Sodium 10mg per tablet.
• Form: Beige, rounded-square, film-coated tablets.

Side Effects

Common

• Neuropsychiatric: Headache, dizziness, drowsiness.
• Gastrointestinal: Nausea, diarrhea, abdominal pain.
• Respiratory: Upper respiratory tract infections, cough.

Serious Risks

• Neuropsychiatric Events:
  • Anxiety, depression, hallucinations, suicidal ideation (rare; monitor closely).
  • Action: Discontinue immediately if mood changes occur.
• Hypersensitivity: Rash, angioedema (facial/throat swelling).
• Eosinophilic Conditions: Churg-Strauss syndrome (vasculitis with asthma; symptoms: numbness, persistent sinusitis).

How to Use

• Dosage:
  • Asthma (≥15 years): 10mg once daily in the evening.
  • Allergic Rhinitis: 10mg once daily.
  • Exercise-Induced Bronchospasm: 10mg ≥2 hours before exercise.
• Administration:
  • Take in the evening (for asthma) or at the same time daily.
  • Swallow whole; do not chew/crush.
• Precautions:
  • Not for acute asthma attacks (use rescue inhalers like salbutamol).
  • Avoid if: Phenylketonuria (contains aspartame), severe hepatic impairment.
  • Drug Interactions:
    • Rifampin: Reduces montelukast levels.
    • Gemfibrozil: Doubles montelukast exposure.

Frequently Asked Questions

1. Is Montebasto available over-the-counter in Kenya?
   For allergies: Yes (pharmacist discretion). For asthma: Prescription-only.

2. How much does it cost?
   ~KES 1,500–2,500 per pack (30 tablets). Generics cost KES 800–1,500.

3. Does NHIF cover it?
   Partially – covered for asthma under chronic illness scheme; not for allergies.

4. Can children use it?
   Yes – pediatric formulations (4mg/5mg chewables) for children ≥6 months.

5. What if mood changes occur?
   Stop immediately and consult a doctor; neuropsychiatric side effects require urgent attention.

6. Are there cheaper alternatives?
   Yes – generic montelukast (e.g., Montair, Montek) costs 30–50% less.

7. Is it safe during pregnancy?
   Use only if benefits outweigh risks – limited safety data.

8. How long does one pack last?
   30 days (1 tablet/day).

Conclusion

Montebasto is a key maintenance therapy for asthma and allergic rhinitis in Kenya, offering once-daily dosing and steroid-free management. While accessible and partially NHIF-covered for asthma, its neuropsychiatric risks (e.g., mood changes) demand vigilance, especially in adolescents. Generics provide affordability, but patients must prioritize regular follow-ups for asthma control. Not a rescue medication – always combine with inhalers for acute symptoms. In Kenya’s high-allergy/prevalent-asthma regions, Montebasto improves quality of life but requires strict adherence to safety protocols and prompt reporting of side effects.
