A clear chest X-ray is great news because it rules out serious lung infections. However, Montair LC (montelukast and levocetirizine) works by controlling underlying airway inflammation and allergies. When you stop the medication, this underlying sensitivity returns, triggering your cough again. This is common in conditions like cough-variant asthma or allergic bronchitis. Please don't worry, but do consult your doctor. They can help identify the root cause and guide you on how to safely manage or taper the medication.

Why does my long-term cough return every time I stop taking Montair LC, even though my chest X-ray is clear?
