Hello, History noted. All the medicines you have mentioned has same basic medicine , paracetamol and the names indicate different brands. As told by your doctor, kindly use Frisium since it will prevent seizures. If P250, for his weight and age give 3.75ml, which is difficult to measure, so give 4ml four times a day. If the fever does not subside or frequency becomes more, take the kid to your paediatrician for examination and further work up. Dengue fever is more on the run now a days, hence take care. Good day.
