Q: Are These Possible Side Effects of Lithium?
Hello, I'm 20 and was eventually diagnosed with bipolar disorder at the
beginning of the year. I'm on 800mg of priadel (lithium) a day and since
starting I have been experiencing what seem to be minor seisures, muscles
randomly jerking, strange pins and needles/distancing from the world and
confusion, at least once falling unconscious for about 10 minutes.
Last time my levels were checked they were a little low but in the ok range.
I've found taking diazepam helps stop them but i'd rather not have to do that
Is this a normal or possible side effect of the lithium? I'm not really sure
what to do about it.
Thanks for any help you can give
Dear Ms. C' --
Not a normal side effect, but muscle twitching is a lithium side effect all
right, and so might be the confusion, as that is a common side effect of blood
levels that have gotten too high. I had a patient get these kinds of effects
with a blood level of 1.0 (where usually we would not expect to see such side
effects until the level was at least 1.2 or so). So it seems plausible that
what you're experiencing is coming from lithium all right, but not conclusive.
And one would not generally think that Valium would help if this was coming from
lithium somehow being too high; indeed one would think that if anything, that
would make it worse.
Given the Valium effect, one has to wonder if what
you're describing is coming with some sort of panic attack or fear response, as
the pins/needles thing, the "distancing from the world", are classic symptoms of
panic attacks. However, confusion is not, and certainly going unconscious is
not. So from this side of the pond it's hard to say just what is going on there.
I'm primarily trying to give you some support for continuing to consider the
lithium as part of the problem. As one of our American doctors said almost a
century ago, "medications are guilty until proven innocent." I hope by this time
that you and your doctor have had conversations about whether you should lower
the lithium to determine its role (DO NOT do that on your own, of course; there
should be a very deliberate plan with your doctor about you're going to figure
Based just on what you've explained here, I'd be
wondering if somehow lithium might be part of the problem, and panic attacks (or
some mechanism like that, lowering bloodstream CO2) another part. As you say,
"I'm not really sure what to do about it" either, other than organize a
systematic inquiry, with your doctor, to determine if lithium could be playing a
role (while at the same time making sure than if you lower it, there is some
other plan in place regarding how your symptoms will remain controlled, so that
they don't recur while you're tinkering). Good luck with that.
