Hi chitchat,
Iron deficiency can coincide with thal minor, but caution needs to be taken to make sure you don't get too much iron, because iron will not correct the low Hb level that is related to thal minor, so once your level is where it needs to be, iron should be discontinued. If your level is still low and more infusions are required, make sure you are given an antihistamine like benadryl before the infusion, as this will help cut down on side effects. If the shaking persists, it may be necessary to try a different form of iron in the infusion. You should be checked for serum iron, serum ferritin and TIBC, total iron binding capacity.
