What Causes Sore Throat And Hives On The Hands After Taking Adderall?

I have recently began taking 20 mg Adderall for my ADD, which has worsened significantly since I became premenopausal. I am experiencing a sore throat and hive-like bumps on my hands and forearms. Is this an allergic reaction? I have seasonal allergies and am allergic to morphine and had allergic reactions to amoxicillin. I am also taking lovastatin, effexor and a generic zyrtec. I m 52 and overweight, but otherwise in good health.
