Q: Too Much Depakote for Age 68?
My Father was diagnosed with Bipolar disorder 3 1/2 months ago. He was
diagnosed 1/ 1/2 months after having hip replacement surgery and not sleeping
for four days straight while he was in the hospital. After he came home he was
still not sleeping much. At first when they were not sure why is was so
wound up and not sleeping they put him on Zyprexa to help him sleep, which it
did. After he stared showing more signs of Bipolar (manic episode) they
added Depakote to his medication. He started taking 500mg a day, five days
later his Dr. increased it to 1000mg. It seemed to be helping a little.
Ten days later his Dr. increased it to 1500 mlg. This is when things started to
go bad. My Dad turned into a totally different person, almost zombie like.
He is normally very outgoing, friendly, and talkative. He also has a
strange feeling in the back of his head that comes and goes throughout the day.
He describes it as feeling like he has cotton in his head. His Dr.
gradually took him off of the Zyprexa because of the side effects it can
cause. After a week or so of not sleeping well the Dr. put him on Seroquel
(50mg) to help him sleep and also to help with the depression he was now
apparenty having. He says he feels a little better and his energy level is
a little better, but he is still not himself. He still talks very little
and can't seem to think or make decisions for himself any more. He used to
always stay busy doing chores and projects around the house. Now he just
sits around the house and asks my Mom what he should do. He also still has
the funny feeling in the back of his head.
I heard that elderly people should start out with a low dose of Depakote.
Could it be that he is taking too much for his age? He is 68 years old and
weighs 170 pounds. The lab shows his depakote level is only 78. Do you
have any suggestions on how I can get my Dad back? Other family members
and friends are shocked when they see how different he is.
Dear Sharon --
Sounds like you're really worried that the Depakote is the culprit. It would be
easy for me to jump in with you on that from the way you've put the story
together here. I have to be careful and imagine that someone else (at least
perhaps the doc') might tell the story differently. But shall we say that on
the basis of the information you've presented here, it does make one scratch
one's head about whether it might be reasonable to try turning down the Depakote
a bit, especially now that there's some Seroquel in there as well (i.e. why did
it get turned to 1500? presumably because 1000 wasn't enough at one point,
perhaps even with some Zyprexa on board at that point? but now, you might hope
that he could do well on 1000 mg of Depakote -- particularly if there is
something else in there now that you could hope was adding to whatever the lower
Depakote might be able to accomplish).
Perhaps a more useful general point, though, which also
supports your working theory and what you'd like to see done, is my primary care
doctor friend's way of putting it: "medications are guilty until proven
innocent". It doesn't matter what the blood level is, though if it had been 130
that might have told you something. The only way to know for sure that Depakote
hasn't messed things up is to turn it down, and finally off if necessary to know
But of course, in the meantime there's the risk of
worsening of symptoms again, and there is no guarantee you can say "whoops, turn
it up again" and get back to where you were, you see. So there's an even bigger
risk than just having some symptoms return while you're figuring it out.
However, older folks can react to doses that rarely
bother a 20 or 30 year old, so I'd agree on that basis as well that the Depakote
might be causing trouble at this dose. They make a 125 mg version (two in fact;
the one I like is the "sprinkles" version, made for kids) so you could wonder
out loud about just turning it down a little bit and see what happens.
One more thing supports your view: I tell patients
that when the Depakote dose is too high, they'll know, because they'll get a
funny feeling in their head, sort of like a headache but not quite, very
unusual, like nothing they've had before. Here's how that's stated in the
handout I wrote 4 years ago (on my website if you want to
Too high a dose causes a “spacey”, foggy
feeling; a mild but constant headache; and occasionally mild blurring of
vision. If you notice these, move your dose down one pill and continue that
dose until your next appointment.
You might ask your dad if there's been any change in
his vision. If so, that would just about clinch it. But be careful about how
you approach the doc' about this. Here are some thoughts about
doctors. Good luck.
