Can rhodiola cause stomache a he's and jittery feelings if i am also on prozac (fluoxetine) and thyroid meds?

Who knows: What's in it or what harm it could do. Why are you taking it without knowing? In addition you're taking Cytomel (liothyronine) which shouldn't be taken by humans and can easily cause the symptoms you're mentioning. That's why (among many other reasons) you shouldn't be taking it. Do you really have a thyroid deficiency? If so, take brand name T4 in appropriate doses. Talk w/your doctor.
