Q: Feeling Almost Manic, Could It be the Prometrium?
Hey Dr.Phelps, I was diagnosed with bipolar disorder 4 years ago and
am currently on Lamictal 200 mg hs, Seroquel 200 mg hs, desipramine 50 mg hs,
and Klonopin 0.5 mg hs. The last year I have been having VERY irregular periods
and recently went to an endocrinologist and was put on prometrium; 100 mg hs
Days 7-13 and then 100 mg in the a.m. and 100 mg hs Days 14-26. Before I was
put on the prometrium I was having a period, felt great the week after my period
when my estrogen and progesterone were at their lowest, and would then launch
into full blown PMS (labile emotions, moodiness, depression, bloatedness, etc.)
for the next 4-5 weeks until I would have another period. So, I felt like I was
living in a PMS state all the time. Now that I am on the prometrium I feel
almost manic. I have felt like my senses have been very heightened, energy
inside that I feel like I can't get rid of, more sensitive and labile and
slightly paranoid. My question for you is...
Could this be from the prometrium? or if this is treating part of my mood
disorder more directly would I possibly be needing to go down on my other
medicine. I feel like I have too much of medicine on board right now, I feel
different. I'm concerned I need to change something with my meds, but I don't
know what it would be. I know I can't continue to live in the chronic PMS state
that I was living in. Any ideas Dr. Phelps?
Dear Rachel --
Well, this is a little tricky. There are multiple possibilities
and I should not be trying to offer anything that even looks or sounds like a
diagnosis for the phenomenon you're describing, because of the several ways it
might be explained. However, here are some ideas to explore with your doctors.
First of all, hopefully the Prometrium (progesterone) is a
short-term deal designed to help get your menstrual cycle back on a regular
pattern. That's how it is often used in this circumstance, if I understand
correctly. In that case, the stuff that is going on now is temporary and the
bigger question is what to do after this. In some respects, there might be some
good news here: it does sound as though your mood symptoms are strongly
affected by a reproductive hormones (that might strike you as a massive
understatement). A common recommendation (it does not have a great deal of
research behind it, yet I have still seen it done often) under circumstances
like these is to use a low-dose birth control regimen to maintain a more "steady
state" in reproductive hormones. Interestingly, I have seen this help; I have
seen it make things worse; and probably most often, it has no impact at all.
But it is relatively simple, and if it was clearly helpful, it might set the
stage for tapering off something that you are currently having to use to
maintain mood stability.
Secondly, speaking of mood stability: since what you are describing
could be described as "rapid cycling" (albeit driven perhaps primarily, or even
almost entirely by reproductive hormones), then desipramine has to be examined
as a potential contributor to rapid cycling (most mood experts accept this idea;
for details see my antidepressant controversies page, the
section on rapid cycling). Since you have
Lamictal and Seroquel as potential antidepressant agents, if the desipramine
came long before those, perhaps you might be able to manage without it now. (If
on the other hand it was added after them, and demonstrated benefit, the issue
is more complex).
Relatedly, could Prometrium somehow be making desipramine
exacerbate manic-side symptoms when before, in a different hormonal environment,
desipramine was fine? (I think it would be much less likely that Prometrium
could cause any of the other medications to make things worse). That is an
interesting idea. To my knowledge, we have no data from which to comment on
Finally, another idea to explore with your physicians would be
whether the irregular cycles might be a manifestation of "polycystic ovarian
syndrome". This may have been investigated already. We do know that irregular
menses are a symptom of PCOS. The reason to consider this, if it has not been
ruled out, is that there is a fairly straightforward treatment for it (metformin).
I mention this because metformin has recently been used by psychiatrists to
block weight gain associated with medications like Seroquel. That whole story
may not be relevant in your situation, but just in case it might turn out to be
a part of a solution, I thought I would mention it.
Good luck getting it all figured out --
