my son is 13 years old. he is suffering from cough with phlegum for last six months. the doctor advised for pft, chest x-ray, blood test and sputum examination. from pft thereport says fev predicted %=56. chest x-ray shows cx12 and referred more cardiological diagnosis . from blood test wbc=11.6, eo= 0.87+, aec=870/cmm.the sputum exam report is negative. the doctor prescribed ODIMONT FOR 30 days, p2ID for 30 days , lupitus syrup for 15 days and formonide forte with turbospin for 30 days. is the prescription over dose? i gave him all the medicines except the inhaler as i thought that if someone takes inhaler it will be of a lifelong use. Now if his cough is cured for one day , the next day it returns. what should i do? should give the prescribed inhaler?????????
