Hi
Welcome to the MedHelp forum!
A fever of 107.8 degree farenheit is abnormally high for a child and can cause serious problems. Please rush to the ER and get this evaluated. Either the fever medicine dose is not enough or he has some serious infection, viral/bacterial.
Please let me know if there is any thing else and do keep me posted. Take care!
take him to ER NOW... Goodness you should not be waiting and being on computer, take him to the ER.
