Hi again Dilantin and PWP--a followup to my earlier message I checked with our clinic and this was what they said--- If the PWP has seizures and a comfirming EEG, Dilantin is indicated. As far as they know It does not cause problems with the Parkinson medications. The 'blackouts' our chapter member has are due to sudden drops in his blood pressure. Thus he does not need Dilantin Anne Rutherford [log in to unmask]
