I'm sorry to hear about the persistent dry cough. A dry cough lasting for two months, especially at night, can be quite uncomfortable. Since your doctor mentioned dust as a possible cause, it suggests an allergic or irritant-related cough.

Here are some steps you can consider:

• Minimize Dust Exposure: Keep your sleeping area clean and dust-free. Use dust-proof covers on pillows and mattresses, and regularly wash bed linens in hot water.
• Air Quality: Use an air purifier if possible, and ensure good ventilation in your room.
• Avoid Allergens: Besides dust, avoid exposure to smoke, strong perfumes, or other irritants that may worsen the cough.
• Hydration: Drink warm fluids like herbal teas or warm water with honey to soothe the throat.
• Medication: There is a medication called Telekast A Tablet, which contains Acebrophylline and Montelukast. It helps relax airways, reduce inflammation, and manage allergic reactions related to respiratory issues. However, this should only be taken under a doctor's prescription and guidance.

Since the cough has persisted for two months, it is important to follow up with a respiratory specialist (pulmonologist) to rule out other causes such as asthma, allergic rhinitis, or other lung conditions. They may recommend further evaluation or treatment tailored to her condition.

If symptoms worsen or new symptoms like breathlessness, fever, or chest pain develop, seek medical attention promptly.To narrow down potential causes, we will need some more information.Please enter your age.
