Hi Asthalin is the brand name of a medicine called salbutamol used in asthma. If the diagnosis is cold, then Asthalin is not required. It should be replaced with Sinarest Drops (0.2 ml) 2-3 times daily. If the nose is blocked I suggest you put one Sinarest Vapocaps in boiling water (steam) near the bed in the room where the infant sleeps. Also use nasal saline drops and nasal suction for blocked nose. Infants are unable to take milk if their nose is blocked and they cannot breathe. If steam inhalation with Sinarest Vapcaps solves the problem, there is no need to take any medicine by mouth. Also, if coughing is not resolving and is associated with fever and breathing problems, I would recommend a chest X Ray. Also , gastroesophageal reflux disease can be cause of coughing in an infant. So in my opinion, take following measures: -keep head end of your child slightly elevated while lying down. -burp him properly after every feed. For further information on this, do contact us.
