I am getting off keppra and I am taking dillantin as a back up to go off them. I was on dillantin a year ago for 8 years but then they stopped working so that is why the doctors put me on them for a short term until I get off the keppra as it was having too many side effects. I have been on the dillantin now for 2 weeks with 1 100mg dillantin in the morning with a 500mg of keppra and 2 100mgs of dillantin at night with another 500mg of keppra. I have so far cut out 1000mgs of keppra. The serum level just recently after increasing dillantin to 2 at night instead of 1 has increased to 78 from 36 with just 1 dillantin at night. Doc siad increase to 2 dillantin at night then it went to 78 for the serum level. I am a female and I have partial complex seizures. When I was on just dillantin I had tonic clonic then I went to keppra and My pattern changed to complex partial. The problem is I am so dizzy and unsteady on my feet since taking dillantin with keppra. I have shaking of the hands back again since being put on the dillantin and the gum bleeding. But the dizziness is virtually all day. I drink water it might go for 1 hour and then its back. Yet at night it doesn't occur. My doctor suggested that because I still have the night time dosage in me in the morning that is why I am so dizzy and unsteady on my feet. So she said cut out the half keppra at night. I am worried that just having 2 100mgs of dillantin at night won't be enough. What do you think.? thanks regards collcat46.
