From this study (3 years ago):
I have been on Dilantin for 6 years for a stage 4 malignant brain tumor that was successfully removed. In the last six months I have had hives, swelling, anaphylaxis, ER visits, blood tests for food allergies... etc. etc. I am taking Doxepin, Singulair, Prednisone, Ranitidine, and clarinex - all prescribed by my allergist. However, I still have awful hives covering my body.
