Dear Sir/Mam, My 4.5 years son and 1.5 years son got cold (sticky running nose) since 5 days. The elder one developed mild cough from yesterday. Both of them don't have any other issues and no fever as well. I was using syp of Cetrizine Hydrochloride and Ambroxol Hydrochloride (3 ml for elder son) from Day 2. But no change in symptoms. So I took them to Pediatrician on Day 4. Dr. Suggested him Syp. levocetirizine dihydrochloride (3.5 ml) and steam for elder son. Should I start this new syrup? Or any better treatment? Kindly suggest.
