Comments from related studies:

  • From this study (1 year ago):

  • At its worse I am unable to stay standing and will fall with no warning whatsoever. These seizure type episodes last a while.


  • 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.


  • From this study (5 years ago):

  • had an allergic reaction to augmentin...have been told to take the vistaril and benadryl every 6 hours, also on a declining course of prednisone (currently 60 mg a day - 3rd day today)...stopped augmentin 3 days ago....hives are less but continuing to get some new ones every day since - is this to be expected?
