if you are diagnosed with a casein allergy your doctor may have you carry a shot of epinephrine with you in case you accidentally eat a food containing casein and suffer a reaction. your doctor will show you how to give the shot. you may also want to keep an over-the-counter antihistamine on hand to help alleviate allergy symptoms. if you experience a severe allergic reaction with symptoms of anaphylaxis call 911 for emergency help and give yourself the shot to counteract the reaction until help arrives. because up to one-third of anaphylactic reactions can have a second wave of symptoms several hours following the initial attack you may need to be observed in a clinic or hospital for four to eight hours after the initial reaction.
