Hello, My son (3 yrs old) was suffering from cough and cold and was coughing. Eventually,  we visited a doctor and he suggested syrups,( Asthalin & Fenoride). But, after having the above syrups, my son couldn't sleep because of his condition got  worsened and his coughing used to get escalated in the night. So, just want to know if those medicines are correctly prescribed by the doctor. Thank you
