The medicines are budecort, duolin , budesol respules and other in take medicines such as alspan syrup, ambrodil s, claribid antibiotics, and meta nasal spray , etc., yesterday we took my grand son to the ENT Pediatric specialist once again and the doctor prescribed the following medicnes. livolin .63 respules, duonase nasal spray, and montair lc kid for two times. however, yesterday night after using the livolin respule my grand son got effected heavy cough continuously from 11-00 p.m. to 3-50 morning with a gap of two minutes and vomiting white sticky watery.
