question: My granddaughter is 4 yr old & is on medication fo primary complex ( rifampicin, isonizid & pza) for less than a wk now. Are ther effects that we must be worry about? I know t liver damage is one effect, can this giv other problems like recurrent fever? Just this morning we notice a slight blood ( very small amount dry blood on one of her teeth-upper). Must we be alarmed? Thank you. God bless.
