Since Monlevo is no longer effective, your body may have developed tolerance, or rainy-season triggers, such as mould and dust mites, have intensified. Alternative Medicines: Nasal Steroid Sprays: Sprays like Fluticasone or Mometasone are highly effective first-line treatments for a morning runny nose and congestion. Alternative Oral Antihistamines: Your doctor may switch you to Bilastine or Fexofenadine. Permanent/Long-term Treatment: Allergen Immunotherapy (Allergy Shots/Drops): This is the only treatment that targets the root cause by gradually desensitising your immune system to specific allergens for long-lasting relief.Please consult an allergist or ENT specialist for a proper allergy test and a personalised prescription plan.
