Likely: The reaction from codeine, Vicodin, Morphine etc are not truly allergic reaction but from these drugs' ability to release histamine from your cells. Thus you will not likely tolerate any drug in the opiate group. NSAIDs can also cause hives (which are considered allergic in some) but more likely aggravates an existing episode of hives regardless what may be causing it. Need more information.
