Q: Thyroid Treatment Approaches
I have suffered from depression most of my life. Nine years ago I
developed hyperthyroidism. At the same time I was put on an
anti-depressant, I became manic. I was put on Lithium and told to
never go on an anti-depressant unless I was on Lithium first. I can not take
any type of anti-depressant or any other psychotropic drug because they raise
my liver enzymes. My thyroid gland was partially ablated nine years ago and I
was put on .1 Synthroid. I have suffered from mood swings, depression,
constant insomnia (which is a major problem)and
(which I take Ativan at night).I have been off and on Lithium ever since.
I am not on it now.
I recently ask my PCP to go on Armour Thyroid because
I thought my problem is a Thyroid issue more than a Bi-polar issue. He
refused. I then asked a psychopharmacologist who placed me on a time
released T3/T4 (equivilent to .1 Synthroid). It seemed to elevate my moods
but I started becoming very fatigued. After a month, he tes!ted by T3, T4,
and TSH. He said my T3, and T4 were in normal range but my TSH was 27.
He told my to go back on the Synthroid and find a different PCP. I am
limited to Lithium (because of my liver enzymes) if I take medication for a
Bi-polar Disorder. I have no anti-depressent options because of the liver
enzymes. Am I on the right track with a T3/T4 combination. If so,
the psychopharmacologist will not prescribe it because of the high TSH level.
Can you help me unravel this problem in a way I can present it to someone to get
adequate treatment. I have to take the Ativan at night (I can not come
down enough to sleep and it helps control my highs). I feel like (a
car that the driver has his foot on the gas peddle and on the brake at the same
time). I have a real problem with depression, lack of motivation, fatigue,
weight gain, mood swings, insomnia (all symptoms of borderline hypothyroidism).
I would greatly appreciate any help you could give me. I have been
search!ing and researching for an answer for nine years. Thank you
Ms. J' --
Well, I'm sort of honored that you would think to ask me this
question. It's a very good question, and it sure sounds like you have
found an aspect of your symptoms, in the thyroid component, that is a critical
aspect. But I must preface my comments by noting that I have virtually
no expertise in this area -- only some hunches based on some of my patients'
experiences. On the other hand, when I read what endocrinologists write,
including a recent scholarly review that acknowledged the role of T3 more
strongly than anything I've seen otherwise from endocrinologists (Wiersinga:
Thyroid Hormone Replacement Therapy, 1999), then endocrinologists don't seem
to know a whole lot more than I do about how thyroid relates to mood disorder
symptoms, and what to do about it.
contrast, there's a small group of psychiatrists researching thyroid as a
treatment, and a smaller group researching what the heck the relationship of
thyroid and mood is based on. From these groups I see only encouragement
to try thyroid approaches as long as one takes care not to overdo it, as then
the risk side of the equation tilts to more prominence (meaning that at low
doses and done cautiously, e.g. not supressing TSH below 0.5 and leaving it
there, there appears to be relatively little risk in trying thyroid
However, what to do with
your TSH of 27? Well, for one thing, when I used too little thyroid
hormone on myself trying to figure out
my TSH reached 30 and I wasn't too terribly symptomatic. The
point there is that you could be doing a right thing, but just not enough of
it, and have your TSH go that high. However, you might be a different
case and someone who can get dangerous symptoms from pushing your TSH back
down towards 1.0. I haven't read of such a thing, but perhaps an
endocrinologist could comment on that for you.
I would think that what you need is an endocrinologist who's willing to take
Wiersinga's review, and take the last few paragraphs (you'll need the full
text version to read this yourself) seriously, wherein Dr. Wiersinga says that
we need more research on T3/T4 combinations as replacement. He's right
that we have little research to go on, and this argument leans strongly
on a single article by Bunevicius in the New England Journal in 1999;
and quite a few endocrinologists pooh-pooh that article.
the other hand, the point you could try to stress to your endocrinologist is
that the usual approach is to get your TSH down toward 1-2, and that you just
want to try doing that with T3/T4 instead of T4 alone. There is a small
additional risk to your heart you are taking with this T3/T4 approach,
relative to T4 alone. You could offer to lower that risk by taking your
T3 component (available separately as Cytomel) in 3 or even 4 separate doses,
to keep each "hit" -- they theoretically only last a few hours of
the peaking blood level -- smaller for your heart. Even this precaution
is extreme, compared to the standard practice in psychiatry of giving 25 mcg
of T3 to people with normal thyroid function, which has been done routinely as
an antidepressant adjunct, for years. No warm up, just boom: add 25 mcg
of T3. That's up toward double the T3 dose I use when combining T3 and
T4. So I hope you can see the point in here: the combined version just
doesn't carry much risk compared to T4 alone and people don't hold back on the
latter when trying to get your TSH down, so you could argue that they
shouldn't have to be so scared of the combined version either.
I'm not a internist; or an endocrinologist; or a cardiologist. I'm
telling you what little I've learned so far based on very little experience,
and some reading of the literature available to me on this subject. You
should check out all these things with another hopefully more experienced
authority. I hope some of this proves to be useful to you.
