A recurring cough and sneezing every 20 days strongly suggests an underlying allergic condition, such as allergic rhinitis or cough-variant asthma, rather than a simple cold. Kuff-D syrup only temporarily masks symptoms and is not a long-term solution. Please stop self-medicating your child, as repeated use of cough suppressants without a diagnosis is not recommended. I advise consulting a paediatrician for a proper evaluation. They can pinpoint the exact cause and prescribe appropriate, safe treatments like antihistamines or preventive therapies. Meanwhile, keep a symptom diary and try to identify potential environmental triggers like dust, mould, or pollen.

Occasional cough along with throat irritation or a feeling of mucus in the throat is commonly caused by allergy, post-nasal drip from sinus or cold, throat infection, dust exposure, smoking, acidity, or dry weather. In many people, mucus collects in the throat due to irritation from allergies or sinus drainage, leading to frequent throat clearing and coughing, especially in the morning or at night. Drinking plenty of warm fluids, doing steam inhalation, and gargling with warm salt water may help reduce irritation and loosen mucus. Try to avoid cold drinks, smoking, dust, strong smells, and very spicy or oily foods if they worsen your symptoms. If acidity is contributing, avoid lying down immediately after meals and reduce tea, coffee, and late-night eating. Maintaining good hydration and using a humid environment may also help soothe the throat. However, if the cough continues for more than a few weeks, becomes severe, or is associated with fever, breathing difficulty, wheezing, chest pain, blood in sputum, or weight loss, you should consult a doctor for proper evaluation. The doctor may check for allergy, sinus problems, acid reflux, asthma, or infection and suggest treatment accordingly.
