Hi..my baby is having a very bad cold and cough since 1 week now..to the extent that if we give him some food he vomits and all cough comes out..We have him broncolyn (terbutalinr sulphate) 2.5ml 3times a day and used ocean spray nasal spray too. Yesterday he had 101 F fever so we gave him some adol. But don't see much improvement.can I give him some fenistil and ambroxol now ? What's the dosage for a 20month old baby?
