Hello dear, The symptoms as mentioned in your post can be attributed to acute exacerbation of asthma, secondary to respiratory tract infection. Management involves: 1. A course of antibiotic to control the causative organism. 2. Levolin & Budecort nebulizer- provide symptomatic relief by causing broncho-dilation (dilating the smaller airway passages, relieving the obstruction & increasing airflow to lungs) Can be used whenever he is having an acute attack. 3. Antihistamine & anti tussive preparations for symptomatic relief. 4. Maintain adequate hydration & a healthy balance diet. 5. Also make sure that he is well protected from cold, dust & other allergens. So, kindly consult a Pediatrician/ Pulmonologist for proper clinical evaluation and start treatment as advised. Wishing him a good health. Take care.
