question: Hi Doctor , My son is 22 months old and weighs 11kgs . Recently he has been coughing a lot (not dry cough) and had slight temperature last night. I called the pediatrician and he advised us to give 2.5ml of Ambrolite-D, 3 times a day . Will that be ok. What is the difference between Ambrolite S and D ? Regards, Gokul
