How Much Mefatal Spas Should I Give A Child With Persistent Fever?

Hi, My ward is suffering from 102 fever since 10 pm yesterday. We gave 5 ml at 10 pm yesterday and 3.5 ml at 2:30 pm early morning, but he is still suffering. Now I want to give the Mafetal Spas. How much do I have to give to a 5-year-old, 19 kg weight.
