Montair LC combines montelukast and levocetirizine, which are used to manage allergic conditions by reducing inflammation and blocking histamine effects. However, if your dry cough persists, especially at night or early morning, it might be due to other causes such as asthma, postnasal drip, or gastroesophageal reflux.

It's important to consult your doctor for a thorough evaluation to identify the exact cause of your cough. They may recommend additional tests or treatments tailored to your condition. Meanwhile, avoid irritants like smoke or allergens, and keep your sleeping environment clean and humidified if possible.

If your symptoms worsen or you experience difficulty breathing, seek medical attention promptly.
