Has anyone experienced iron deficiency anemia while taking Cosentyx infusions?, my symptoms of low iron began somewhere between the time I stopped taking Simponi Aria infusions and when I began having Cosentyx infusions, now almost a year later I have to get iron infusions, while my symptoms of insomnia and fatigue have worsen, only been able to stay in bed for at three to four hours at a time only having solid sleep about an hour at a time to two hours max.
