Its better to go for a Cronin tablet 1 tab as per his weight as the recommended dose is 10-15 mgkg of body weight. For such high grade fever not responding to Cronin, try using Sup Metal P at 7.5 ml every 8 hour. In case he continues to have high grade fever after 1 day, do consult your physician for proper clinical examination and laboratory tests if required based on examination.
