Hi, my son is 13 months old and weighs 9.7 kg with 76cm height. Last week he had fever and running nose so had taken medicine for it for 5 days. Now it's already past 4 days since the dosage is finished. But running nose is still there. But no fever and appetite is good too. He is active too. Medicine used are acythromysin and relent +. What can I do? Can I use relent plus syrup again? Or will it resolve on its own? Note. Food he is having normal soft food and fruits like mango too and consume lactogen 3
