Geodon(Ziprasidone) has a known major side effect, QT prolongation. Other symptoms that you mention probably are common to all anti psychotics. Some people are more immune to the side effects of anti psychotics. Other’s are more prone to side effects. But the fever side effect must be brought to the notice of the doctor because fever indicates another side effect common to all anti psychotics, NMS(Neuroleptic Malignant Syndrome). Though not all fever’s indicate NMS.
When I tried Ziprasidone a few years back , I got the side effect, QT prolongation when I combined Ziprasidone with Quetiapine which also prolongs QT interval. I got Syncope and fell on the bed unconscious for nearly two hours. I somehow regained conscious and discontinued Ziprasidone there after. Actually it was doctor’s fault to combine those two medicines. In your case you report the fever to the doctor and take his opinion and act accordingly. Not all doctor’s commit mistakes!
