<s>[INST] My son is 2 yrs 6 months. Diagnoised with severe chest congestion and cough mucolytic. Doc said mild bronchitis. Prescribed Ascoril syrup 3.5 ml 3 times a day for a week. After giving medicine cud see some restlessness and adamancy at night which was uncontrollable. Now 4 days over. He is better but a bit dull. His cough though l not fully gone but bettet. Is it normal [/INST] Thank you for consulting in HealthCareMagic. The condition that you mention, is probably bronchiolitis and not bronchitis. It is a viral infection that affects children between 6 months and 3 years of age. It is characterised by chest congestion and wheezing. In order to dilute the cough steam inhalation or nebulisation is required alongside the mucolytics. Generally it is associated with an allergic component for which the antiallergics like ascoril are given. The side effect of such antiallergics is drowsiness and hence the child seems dull. The cough and restlessness would get relieved in a few days time and I insist that you bear with it till then.Hope my answer was helpful for you. I am happy to help any time. Further clarifications and consultations on HealthCareMagic are welcome. Wish your kid good health. </s>
