what happens if the prepared injection does not protected from light?

 Hello

 I just received my 3 Amevive injection and my t cell count as well as T cell subsets are continuing to increase despite the alefacept therapy. Somehow the drug is failing to work.

The injection should be protected from light I guess and in my clinic I saw the injection coming from pharmacy to the treatment room without light protection. Is it possible for this to decrease the drug's effectiveness or???
