Q: Unsteady Pupils Associated w/these Meds?
I am dx'd with BPII and BPD. I currently take 20 mgs Celexa (since Dec/05),
300mgs Wellbutrin SR (since spring 2000), 1.5mgs Risperdal M-Tabs (on and off
since Jan 2000) and 1250mgs Epival (Depakote) (since...? 8 years ago).
I have had regular eye exams every two years or so with slight changes in RX
glasses. Have had problems with right eye turning outwards sometimes and
occasional double vision. Optomatrist says I have weak eye muscles..but...he
also noted "unsteady pupils" which he indicated could be my med side effect or a
neurological problem. This is the first time that it was detected so I am on a
list to see an opthmalogist (which might take a while I'm told) to do a neuro
In your opinion, could the unsteady pupils problem be
associated with my meds?
Thanks for your input.
Dear Sharon --
Hmm, that's going to be tough. There are several ways one could cook up an
explanation for "unsteady pupils" and relate it to one or more of these
medications. The problem with unusual possible side effects like this is
that even if you find it on a list of medication side effects somewhere, there's
no guarantee that explains the symptom. Of course we usually go back and try to
figure out when the side effect showed up, to see if we can relate it to when a
particular medication was started (or perhaps when another one was started that
might somehow have interacted, e.g. if risperidone was added after Epival (valproate;
Depakote in the U.S.), as there is a minor interaction there where the latter's
blood levels can go up some)(I ran those four medications on a
nifty interaction site and this is the only interaction that came up). And
of course that's why you mentioned the time frames for
valproate and risperidone,
suggesting that they don't seem to be the obvious candidates for this problem.
So, what happens if no such logic identifies a likely
culprit is that to really know that none of the medications is causing this, you
have to go off them (NOT on your own, of course, particularly with this kind of
collection; your doctor has to be very directly involved at such a stage),
usually with a cautious taper hoping you'll get a clue as you go down without
going all the way off, and starting with the most likely culprit (risperidone
and valproate perhaps leading that list, as they have more side effects like
this, occasionally, e.g. valproate can commonly cause blurry vision at higher
blood levels -- so it would probably be worth finding out what your valproate
blood level is). Not very helpful, I fear. Be careful with your process here,
working closely with your doctor. Good luck with that.
