Hello Doctor, My son is 10 months old and he is having cold ( basically running nose and in night block nose only) since last almost 2 weeks. Consulted one doctor and he gave Hydroxyzine hydrochloride drops ,Nasivion nasal drop and ambrodil-s for 5 days but no success, situation is same.Now doctor says don't give medicine and leave it like that, it will improve automatically. But it's been 2 weeks and it's not improving. In night when he sleeps makes noise, snores very much. Kindly suggest sometime. Can I give antibiotics like zinthum ds and zincup to boost immunity? Plz suggest what to do. Thank you.
