<s>[INST] My son is 6 and has had a cough going on two weeks we seen dr last Saturday and Wednesday they have some X-rays and swabs for flu and pneumonia and all negative , they even swabbed for pertussis and the results have not came back . But he has been coughing so hard since Wednesday he has been puking up mucus and tonight he has been coughing since 10:30 and puked 7 times. Is there anything we can do or what may this be . He has had predisone, Zithromax and anoxiciilan and something for cough and congestion. Nothing is helping [/INST] Hi, Thank you for asking question on Chat Doctor. Looks like spasmodic cough due whooping cough or bronchiolitis. Erythromycin is the Chat Doctor. Albuterol+Bromine combination 3 times daily and prednisolone syrup 1 mg/kg in 2-3 divided dose will reduce the severity of coughMinimum 10 days treatment is required for prompt relief. Hope this answer will serve your purposeless feel free to ask any more queries if requiredTake care </s>
