Mine have been mild dizziness, only during infusion. Earlier doses gave me rosey cheeks and warm spells but never a fever over 100.2, has since dissipated. Currently, because of higher doses, a metallic taste in my mouth which comes and goes during infusion, along with mild numbness in side of face or lips which also comes and goes. Slight throat numbness. Due to these reactions thry slowed my drip from 4 hours to 4 and a half. Cant slow any more.
