my son has PDD and had throat infection two days ago. The doctor gave him Asithral 200 mg liquid 6 ml for two days. The fever came to normal, but he is cranky for the past two days, we are giving him nutrilin B 150 mg for 5 days, what else can we do to bring down the irritation, his communication skills are poor so he is not able to tell his symptoms. Please advise.
