Mum's change of chemo

Mum starts different chemo on 15th Aug I think it’s called Taxofere?? anyway, the consultant was going through all the risks and side effects and sounds as though things are going to get really tough for her.
Please can anyone help? Has anyone had experience of this Taxofere? Mum is already struggling with tiredness and nausea and her veins seem to be collapsing with the chemo already.
