Thank you for your query,
As the child is having cold
only and there is no fever
the advent forte syrup is not required.
Continue the syrups for cold and cough as prescribed by your doctor and stop advent.
Use only prescribed medication and dont use antibiotics without the prescription as they may not be required and unnecessary use may lead to drug resistance
Take your child to a doctor near by you for physical examination and for appropriate medication.
Hope I have answered your query.
