In brief: Not allergy

Since opiates such as morphine directly releases histamine from the body cells, a good % of the people may end up with itching and even hives from it.
But this is a chemical and not a truly allergic reaction and is usually dose-dependent. Opiates can cause sedation, stomach upset, and constipation but these are not from being allergic. Thus most if not all reactions are not allergic in nature.
