How Can Allergic Rashes Due To Adderall Intake Be Treated?

I developed hives after starting Adderal ER. I started in June ~did not take it everyday. My first outbreak was in June. It came and went quickly but scared me. The second 2 were close together end of July, and early august. The redness did not go away inbetween these last outbreaks.The welts and itching did. I stopped taking it a week ago and still have the red spots. I read the printout that came with the med, and it clearly said hives can be a side effect. I am scared that they are not gone by now~ and concerned it may not have been hives...
