<s>[INST] Hi, My son is 5 years old and he has been having phlegm with mild cough for over 2 weeks. Lastweek when I took him to a doctor, he prescriped Respinil syrup. 2 days back he had fever and I took him to the doc and he prescriped Levolin , azithral ,cetrizine syrup and crocin syrup in case of fever.  His temperature is at 103 and just now it is gradually reducing. But I was searching on the levolin and azithral on google and looks like they are for cough. But he does not have cough now and it is only the phelgm which is causing the fever. So was just wondering that in the medicine the doc prescribed which would help reduce the phlegm? [/INST] Phelgum is manifestation of lower respiratory tract infection. These medications collectively act to improve the infection. Once infection will be cured there will be no phlegum. So continue the treatment. </s>
