A 43 y.o. mother of four presents to the office complaining of fatigue, listlessness,
fluid retention, irritability, PMS, and easy weight gain. These symptoms came
on 8 months ago after the birth of her fourth child. All of her blood tests
are normal, and her body temperature averages 97.8 degrees during the day. She
is started on 7.5 mcg p.o. BID of T3 compound ( p112),
and is instructed to increase the dose by 7.5 mcg/dose/day until her temperature
is 98.6 on average during the day. Her temperature goes up to 98.6 when she
reaches 22.5 mcg p.o. BID. Her symptoms respond dramatically.
She does very well for several days on 22.5 mcg BID, until on the fourth day
on that dose her average temperature drops to 98.0 degrees. At this time, some
of her symptoms return. The dose is increased to 30 mcg BID, and her temperature
goes to 98.6 again and she again does exceptionally well until her temperature
drops back down 4 days later. She is increased then to a dose of 37.5 mcg BID.
Her temperature and symptoms respond for 4 days, then slip again. However, when
her dose is then increased to 45 mcg p.o. BID, her temperature rises to 98.6
again, with her symptoms resolving, and remaining resolved even longer than
4 days.
About 7 days after her temperature and symptoms remain resolved on the dose
of 45 mcg BID, it is felt that her temperature has been "captured." ( p75)
At this time, the patient is instructed that she is likely to do well weaning
off the T3 therapy, and has a good chance of remaining normal off the treatment.
She feels completely well, but is a little reluctant to wean off the T3 therapy
right away for fear of feeling badly again. She has also noticed that she has
lost 5 pounds without changing her exercise or eating habits and wonders if
it would be all right for her to stay on the 45 mcg BID T3 for about a month
or so longer while she works with good diet and exercise to get off the other
15 pounds.
She is without complaints of any kind, so the regimen is continued, and a month
later she is doing well. The following month she is ready and confident to wean
off the T3 therapy. She is able to decrease her dose by 7.5 mcg/dose every 2
days without her temperature dropping, and in a couple of weeks she has successfully
weaned off the T3 therapy. Her temperature has remained 98.6 with her symptoms
remaining resolved, even off T3 therapy.

A 43 y.o. businessman presents to the office complaining of severe fatigue,
difficulty sleeping, and headaches. The symptoms first started about 10 years
ago when his business went into bankruptcy. The symptoms persisted to roughly
that same degree until about 5 years ago he was divorced, at which time his
symptoms worsened considerably. His symptoms worsened yet again about 6 months
ago when his brother died. To him, his symptoms are inexplicable since he feels
that he has gotten over the loss of his brother, and he now is very happily
remarried and the business he now owns is exceptionally successful. All tests
are normal, but his temperature averages a degree low during the day.
He is started on a cycle of T3 therapy. He is started on 7.5 mcg p.o. BID and
is instructed to increase the dose 7.5 mcg/dose/day if he is without complaints
until his temperature is 98.6 by mouth on average, and to call the office if
he does develop any complaints, and to return to the office in 2 weeks. At the
2w visit, the patient relates that he is taking 90 mcg BID and his temperature
is still not up. Since his temperature did not budge at all during the first
cycle and he has noticed no difference at all in the way he feels since starting
the treatment, he is instructed to try weaning off the T3 therapy by 7.5 mcg/dose/day
if he remains without complaints. This is done so that the treatment will not
be unnecessarily delayed. He is able to decrease the dose every day without
complaints.
The patient is then started on a second cycle, with the same instructions as
the first. This time his temperature goes up to 98.6 on 75 mcg BID. His symptoms
begin to improve, but after about 3 days his temperature drops back down again.
The dose is increased to 82.5 and his temperature returns to normal. After about
a week on that dosage, his temperature starts to go down again and he loses
some of the clinical improvement he's gotten. The dose is increased to 90 mcg/dose,
and his temperature goes up again, restoring some of his clinical improvement.
His temperature went down again after an undetermined time (since he wasn't
taking his temperatures very well). Since he had been showing a definite response
to each recent increase, and he was without complaints, he was increased above
the usual maximum dose of 90 mcg BID to see if his temperature could be captured
( p75) with one or two more increases.
The temperature responded and dropped again on the 97.5 mcg dose. Then his temperature
went up and stayed normal on 105 mcg BID and did not drop again.
Since he did not demonstrate any clear compensation time ( p85),
he was left on 105 mcg BID for at least 3 weeks to help make sure that his temperature
was indeed captured. During that 3 week period of time, he wasn't able to take
his medicine very well on time for a few days, and he began to notice feeling
a little headachy, tired, and more on edge. His temperature log revealed that
his temperature had become a little more unsteady at that same time. His temperature
was ranging more widely across his 3 daily temperatures ( p41).
He was then given a T4 test dose of half a .025 mg tablet (.0125mg) of levothyroxine,
and within 45 minutes his complaints resolved completely.
Anxious to see if he might be able to capture his temperature with a smaller
dose of T3 on the third cycle ( p77),
he was weaned off the second cycle. Since unsteadiness of the T3 level had been
demonstrated in the second cycle with the T4 test dose, and since the patient
was wondering how well the T3 therapy was going to end up working for him (even
though he had gotten a fairly good response to treatment so far), it was decided
to let him remain off for 10 days between cycles to let the T3 level steady
down as much as possible so that he could get as fresh a start as possible ( p96).
He tried weaning down off the T3 every 2 days, but with the third decrease his
temperature started to drop a little. Since it looked as if he might have a
cycle or two more to go, he did not increase his dose back up, but simply decelerated
his wean to going down a 7.5 mcg decrement every 4 days ( c12).
He was then able to wean off without much of a drop in his temperature.
On the next cycle, he was able to capture his temperature on 60 mcg BID. His
symptoms were all but completely resolved at this point. He was without complaints.
After a few weeks he was ready to proceed with the therapy and be weaned off
the T3 to see if he could capture his temperature with less medicine on a subsequent
cycle for complete resolution of his symptoms. He decreased the dose by one
decrement every 4 days without any drop in his temperature.
On the fourth cycle, his temperature was captured with 15 mcg BID, and his
symptoms resolved completely. He was later able to wean off the T3, and remain
improved even after the T3 had been discontinued. His temperature remained normal
as well.

A 36 y.o. real estate agent presents to the office complaining of PMS, depression,
fatigue, and admits to a peculiar throat sensation (she says it feels as if
someone is pressing his thumb against her trachea toward the base of her neck).
Her symptoms came on about a year ago. The only thing she can remember about
that time, is that's when she was having some problems with her 12 y.o. daughter,
and that's also when she received increased management responsibilities at the
brokerage.
After evaluation, she was started on a cycle of T3 therapy with the usual instructions.
The day after starting the T3 therapy, she called the office to point out that
her temperature had gone down instead of up. Her temperature was lower the day
after starting than it was before she started. She was also experiencing a little
bit of tightness in the rings on her fingers, but no other complaints. It was
explained to her that she may very well be a one-day compensator ( p91)
and that she was going to need to be extra careful to take the medicine exactly
as possible on time, and to call the office at the first sign of any complaints.
It was explained that her chances of developing side effects might be a little
higher than usual, and she needed to consider whether or not she wanted to proceed.
Also, if she did want to proceed then she would have to increase the T3 very
deliberately ( p98) and carefully,
or not at all.
She opted to proceed, and since it was agreed that the potential benefits outweighed
the risks, her T3 dose was increased by 7.5 mcg/dose/day. Her temperature reached
98.6 on 30 mcg BID, but dropped back down again later that day so her average
was below 98.6. She stated feeling noticeably better when her temperature had
gotten up to normal. She went up to 37.5 mcg and her temperature went up, and
then back down again in one day. This same thing occurred when she increased
to 45 mcg and 52.5 mcg BID. After a weekend, she called to say that she was
feeling more irritable, and bloated, and achy almost as if she had the flu.
Her complaints had started over the weekend. As it turned out she had gone to
the store with her daughter on Saturday morning and missed taking her dose by
about an hour and a half. She denied any irregular heart beats, increased awareness
of her heart beat, shortness of breath, or any other complaints. Her side effects
resolved completely within 45 minutes of a T4 test dose ( p129).
She was able to get a timer and organize herself such that she was then able
to make sure and take her T3 very much on time thereafter.
She proceeded with treatment and was able to capture her temperature on 60
mcg BID. Her symptoms began to resolve, and continued to get better and better
over the next 2 weeks or so ( p103).
She did well on that regimen for about a month or so, until she had a bout
of missing several times her dosage an hour here and two hours there. She began
noticing feeling a little jittery, achy, bloated, and tired. Her temperature
had also dropped about half a degree ( p121).
She responded fairly well to a T4 test dose, but when it was repeated an hour
and a half later, her complaints had not resolved sufficiently enough to comfortably
allow any further T3 increase in this cycle. She was weaned off the T3, so that
her system could settle down, and to see if she could get on less medicine on
the next cycle, which would be easier to manage (easier to keep the T3 level
steady)( p122). She was able
to wean down off the T3 every 2 days without her temperature dropping. Her side
effects diminished more and more as she went off the T3, but did not disappear
completely until after she had been off the T3 for about 3 days, so she was
left off the T3 for another 3 days after that (for a total of 6 days) to give
her T3 level more time to steady down very well ( p133).
On her own she opted to stay off a couple of days more (for a total of 8 days
between cycles) to get a nice fresh start ( p96),
since she wanted to see if she could get as much correction as possible out
of the upcoming cycle.
On the second cycle, she was able to capture her temperature on 30 mcg BID,
and she felt far better than she ever had on the first cycle. Her symptoms were
almost completely resolved. About a week after her temperature was captured,
she wanted to see if she could wean off and stay improved off T3 therapy. To
her amazement, her temperature held as she weaned off the T3 therapy, and her
symptoms actually got better and better. This continued until it got to the
point that her symptoms only resolved completely after she had been off the
treatment for a few days. It was only after the treatment had been discontinued,
that she felt completely normal; she felt better after the treatment than she
ever had during the treatment ( p76).
And after treatment she felt as good or better than she did before she ever
got sick in the first place.

A 50 y.o. woman presents to the office with a long history of "thyroid" trouble.
Her symptoms of decreased energy, decreased ambition, listlessness, dry skin,
fluid retention, and cold intolerance began in her late twenties. She also remembers
a distinct down-turn in her condition after a series of Cortisone shots she
received received when she was 32 years old. When she was 33 y.o. her family
doctor felt her symptoms were characteristic of low thyroid function, even though
her blood tests were just within the limits of normal. He started her on half
of a grain of dessicated thyroid (e.g., Armour Thyroid) to see how she'd do.
Her symptoms responded dramatically well to the Armour, so it was felt his suspicion
of low thyroid was confirmed.
Unfortunately, her symptoms started to return about 3 months later. Her dose
was increased to 1 grain, and she improved again. Again, 3 months later, her
condition slipped back downward. He did not increase her dose at that time.
She took that same dose for many years, and did fairly well. She didn't complain
of any side effects. Occasionally, she wondered if she needed more thyroid medicine
but her doctor didn't agree. Over the years she has been to several doctors,
but none of them felt she needed to take more thyroid medicine since her tests
showed a TSH near the lower limits of normal. About a year ago, a doctor she
was seeing agreed to increase her dessicated thyroid to 1.5 grains to see if
that would help any. Her symptoms improved markedly, and both patient and doctor
were well pleased. She became disappointed when the symptoms started coming
back again about 3 months later. Her doctor, who was somewhat surprised when
her symptoms returned, was even more astonished when he increased her dose to
2 grains only to see her symptoms of hypothyroidism get even worse!
To remedy the situation, a doctor knowledgeable about Wilsons Temperature Syndrome instructs
her (after evaluation) to decrease her dessicated thyroid to 1 grain for 2 days,
and then to discontinue it (she is otherwise in good health, and she hasn't
noticed too much of a change in the way she feels when she skips a day here
or there of her Armour). She is concerned however when she's told she is to
stay off all thyroid (if without complaints) for 10 days before starting the
T3 therapy ( p156). She feels
she needs more thyroid stimulation, not less, and can't picture how she might
feel if she goes off her thyroid treatment. She is reassured that she may start
on the lowest dose of the T3 therapy before the 10 days are up, should she notice
any worsening of her symptoms, and that she may increase the T3 as much as one
7.5 mcg increment/day to prevent any worsening of her hypothyroid symptoms during
those 10 days. Further she is counseled that she'd be better off not to start
or increase the T3 therapy at all for those 10 days if she doesn't worsen ( p156).
She is able to remain off all thyroid without discomfort for 10 days, and then
begins a cycle of T3. She gets to 90 mcg BID without a noticeable difference
in her temperature or the way she feels, so she is weaned off the first cycle,
or reset cycle ( p125). She
is able to wean off by 7.5 mcg/dose/day without complaints.
With the second cycle, her temperature and condition still do not improve in
spite of her reaching 90 mcg BID. The second cycle is weaned as the first.
On the third cycle, her temperature begins to go up, and she begins to feel
better on 67.5 mcg BID. On 75 mcg BID her temperature reaches 98.6 and she feels
even better. Two days later her temperature slips back down a little, and so
her dose is increased to 82.5 mcg BID. 2 days later it slides back down again,
and she is increased to 90 mcg BID. She is without complaints. Her temperature
does not drop back down in 2 days, so the patient begins to wonder if her temperature
is captured. Three days after that (a total of 5 days) her temperature still
has not dropped so it is felt her temperature is pretty well captured.
She subjectively felt about 40% of what she imagined a normal person to feel
like when she started T3 therapy, and now she feels about 60% normal.
She begins having some stress at work, on top of getting the flu, and missing
some of her dose times (she missed one dose entirely), and begins noticing some
lightheadedness, shakiness, and palpitations when she stands up quickly. Her
side effects respond partially to a T4 test dose. Since she is having some side
effects, and since this is a reasonable time to wean anyway it is determined
that it would be best for her to wean off the present cycle at this time. Her
side effects resolve when she has weaned about half-way off the present cycle,
so she is kept off the T3 therapy for only 2 days between cycles ( p133).
On the next cycle she is able to capture her temperature on 52.5 mcg BID, and
feels 80% normal.
After a time ( Q9), she
is weaned off the present cycle, to start another. On the next cycle (her sixth
overall) she is able to capture her temperature on 15 mcg BID and she feels
100% normal, subjectively. This cycle ends up being her last since she is able
to wean off the T3 and stay normal even after the treatment is finished.

A 48 y.o. college administrator presents with extreme fatigue and listlessness,
as well as difficulty sleeping at night, cold hands and feet, and irritable
bowel syndrome. Twenty two years ago she developed hypothyroidism, with a low
T4 and a high TSH. She is well acquainted with some of her symptoms, as she
has had them to varying degrees for the last twenty two years. Her symptoms
are severe enough now, that she "just knows there's something wrong," in spite
of the fact that her thyroid blood tests are normal. She is currently taking
.2 mg of levothyroxine (e.g., Synthroid, Levothroid).
After evaluation, she is instructed to decrease her T4 dosage from .2 mg to
.1 mg for 2 days and then to discontinue it. She is instructed that she should
try to remain off all thyroid medicine for 10 days, but that she should start
and increase the T3 therapy as is necessary (and only as is necessary) to prevent
a worsening of her symptoms. After the 10 days are over, she may then increase
the T3 by 7.5 mcg/dose/day if without complaints until her temperature is 98.6
or until she reaches 90 mcg BID, and to call the office if she has any questions
or problems, and to return to the office in 3 weeks.
At her next visit, she relates that after she was off all T4 for 2 days, her
hypothyroid symptoms started to worsen, and her temperature dropped from averaging
97.8 to about 97.5, so she started taking 7.5 mcg BID. Her symptoms did not
continue to worsen, so she did not increase the dose any further, until 3 days
later (fifth day of being off T4) when her symptoms started worsening again.
At that time she increased her dose to 15 mcg BID, and with that she was able
to hold her own until the rest of the 10 days had passed.
At that point she began increasing the T3 therapy by 7.5 mcg/dose/day in an
effort to bring her temperature up to normal. Her temperature normalizes at
52.5 mcg BID, and her symptoms improve markedly (she feels 80% normal when she
had been feeling 20%).
After a time, it is determined that she should proceed with treatment to see
if she can completely resolve her complaints and go back on T4 therapy ( p162).
She begins to wean down by 7.5 mcg/dose/2 days (and she is further challenged
by not adding back any T4 at first). Her temperature begins to slip after the
second decrease, so it is felt that she may be weaning the T3 dose too quickly.
This suspicion is confirmed by going back up one increment of T3, waiting 4
days before the next decrease (instead of 2), and seeing her temperature hold
this time. She continues to be able to decrease the T3 by 7.5 mcg/dose/4 days
without a drop in her temperature until she gets down to 22.5 mcg BID. She finds
that she cannot decrease the dose past this "wall" without experiencing a drop
in her temperature, so it is felt that she probably is not producing sufficient
T4 to support endogenous T3 production sufficient to replace the exogenous T3
being weaned. So, .025 mg/day of levothyroxine is begun. After a day or so,
she is then able to finish weaning off the T3 therapy without problems. At this
point, she is still feeling about 70-80% normal ( Q5).
Two days after the first cycle of T3 therapy has been discontinued, the levothyroxine
dose is discontinued. She again is instructed to wait up to 10 days without
starting the T3 if possible between cycles (since she is only on .025 mg of
T4 5-7 days would probably be sufficient, but in cases of being on .1 mg or
so, patients should wait the full 10 days). This time, she is able to remain
off the T3 until she decides to begin the next cycle on the sixth day (which
she has permission to do).
With this cycle, she is able to get her temperature up on 30 mcg BID, and she
enjoys complete resolution of her symptoms. When she is weaned off the T3 therapy,
she weans down every 4 days, and again needs .025mg T4 to be added back when
she gets down to 22.5 mcg BID. When she gets down in the cycle to 7.5 mcg BID,
it seems that she could use a little more T4 (based on her symptoms and temperature),
and so her dose is increased to .05 mg/day. She remains very, very well off
T3 therapy, and finds herself 6 months later, with normal thyroid blood tests
and doing far better on .05 mg/day than she ever did on .2 mg/day!

A 38 y.o. woman had been fine until about 3 years ago when she developed signs
of hyperthyroidism. Her T4 was very, very high, and her TSH was extremely low.
She had lost 10 pounds in less than a month, was experiencing a rapid heart
rate, and feeling quite ill. She underwent ablative radioactive iodine treatment,
and her symptoms of hyperthyroidism gradually abated. She began gaining her
weight back, and also felt more fatigued, with difficulty concentrating. A low
T4 and an elevated TSH, revealed that she had been rendered hypothyroid, which
was no surprise. She was started on levothyroxine, and after some adjusting,
her blood tests were normalized with her being on a dose of .1 mg/day. The only
problem was that she was still suffering from the symptoms she had developed
after the ablative therapy. She was still gaining some weight and she was still
exhausted. She also noticed she was retaining more fluid, and was loosing some
hair; she was also developing very dry skin and dry, brittle hair. Since the
thyroid tests were normal, her doctors felt that she was normal, and that if
anything her complaints were from something else if not from simply getting
older. They did not feel that increasing her dose would be indicated or helpful.
She had lived for 37 years previously without any trace of such a complaint,
and she knew she felt nothing like the way she felt prior to developing hyperthyroidism.
The symptoms she was experiencing were just like the ones she began to have
after the ablative therapy, which had partially responded to levothyroxine to
the satisfying of blood tests. Her temperature was running 97.0 on average.
After evaluation from a Wilsons Temperature Syndrome perspective, it is determined that
she should decrease her T4 to .05 mg/day for one day, and then discontinue it.
She is instructed to start and increase the T3 therapy only as is necessary
to prevent a worsening of her symptoms for 10 days (staying off T3 completely
for 10 days if possible) and then to increase the T3 by 7.5 mcg/dose/day if
without complaints until her temperature is 98.6 or until she reaches 90 mcg
BID, and to call the office if she has any questions or problems, and to return
to the office in 3 weeks.
She is able to stay off the T3 comfortably for 10 days after discontinuing
the T4. She is able to capture her temperature on 45 mcg BID. Her symptoms of
hypothyroidism almost completely resolve, but not quite.
She is feeling well enough, that she would like to stay on the 45 mcg BID for
a time, since it has been a while since she's felt very well. After about a
month on that dosage, she comes down with the flu. Although her temperature
had been running normal before the flu, her temperature is now running close
to 100 degrees. Since her temperature had been normal for a while on 45 mcg
BID, she is instructed not to decrease her dose of T3. She is advised to treat
this fever, the way anyone else would treat a fever they would get with a flu,
and to call the office if she develops any unusual complaints. After 4-5 days
her flu abates, and her temperature returns to normal, as does her previous
level of well-being.
After a time ( Q9), it is
determined that she should wean off the present cycle in favor of the next cycle
of T3. It is also hoped that she can avoid having to wean T4 before the next
cycle, by not having to go on T4 after this cycle. She is instructed to wean
off the T3 by 7.5 mcg/dose/2 days if without complaints, and to remain off for
2 days before starting another cycle. It is explained to her, that should her
temperature begin to drop, and should she begin to feel significantly worse
that some T4 will be added back.
As she weans off the present cycle of T3, her temperature slips a few tenths,
and she feels a little more tired, but is sufficiently comfortable that she
doesn't need to add back any T4 between cycles.
On the second cycle her temperature is captured on 30 mcg BID, and she enjoys
complete resolution of her symptoms. She states that she feels the way she did
before any of this ever started (before getting hyperthyroidism). She is allowed
to remains on 30 mcg BID for two months because she does not have any complaints,
and she is afraid she would not feel as well with the T4. Over that time, she
begins to forget what it was like to feel badly, and becomes confident that
she will be able to wean off T3 therapy. Since she is in no hurry to wean off,
and because she wants to stay on the smallest amount of T4 that is effective,
she weans down off the T3 by one 7.5 mcg every 10 days. As she weans down off
the T3 therapy, her temperature slips some when she decreases the T3 dose to
15 mcg BID, so she is given .05 mg of T4. She is then able to wean off the rest
of the way without difficulty. Her thyroid blood tests 6 weeks out are within
normal ranges. She feels back to normal, and maintains a normal temperature
on .05 mg/day of T4 (levothyroxine). These are two things she didn't have prior
to T3 therapy even though she was on .1 mg/day of T4.

A 34 y.o. woman who is part Irish, and part American Indian presents complaining
of fatigue, panic attacks, migraine headaches, and irregular menstrual cycles.
She has a fair complexion and some freckles, and naturally has reddish highlights
in her hair. She has been more tired than she thinks is normal, for as long
as she can remember. Over the years, she has seemed to pick up more and more
complaints. She remembers no obvious correlation between the onset of any of
her symptoms with any identifiable stressful event, or identifiable change.
Her temperature has run between 97 and 98 degrees for as long as she can remember.
"I have to get sick to get a temperature of 98.6, and my doctor used to tell
me that if I ever did get a temperature of higher than 98.6 that for me it was
a fever and to treat it as such."
After evaluation, she is started on 7.5 mcg p.o. BID and is instructed to increase
the dose by 7.5 mcg/dose/day if she is without complaints until her temperature
is 98.6 by mouth on average (or until she is up to 90 mcg BID), and to call
the office if she develops any complaints, and to return to the office in 2
weeks. The patient is very apprehensive about increasing the medicine every
day since she has a history of being very sensitive to medicines. It is explained
to her that she may go up on the medicine by 7.5 mcg increments every 3 or 4
days if she prefers, but that 10% of patients don't tolerate that very well,
and that she might be one of them ( p98).
It is decided that she will increase the T3 every 3 days instead of every day,
but that a careful eye will be kept on her to watch and make sure that she is
not a one-day compensator ( p91).
Her temperature first reaches 98.6 on 37.5 mcg BID. She feels significantly
improved (from 30% normal to 60% normal). After 5 days on that dose, her temperature
drops back down again, and so her dose is increased to 45 mcg BID. About 5 days
later, her temperature begins to slip again, and so her dose is increased to
52.5 mcg BID. Her temperature again goes up, and she again feels well until
about 3 days later, when she missed a couple of dose times by an hour or so
(she admits that she has been having a little trouble getting her doses on time
all along). At this time she doesn't haven't any complaints or side effects,
but she is just not feeling as well as she was. She is given a T4 test dose
( p129) and within 45 minutes
of the dose she returns to feeling as well as she ever has during the T3 therapy.
Two days later (her fifth day of being on 52.5 mcg BID) her temperature slips
down again. She is increased and compensates again in 5 days, and then when
she is increased to 67.5 mcg BID, her temperature appears to be captured (because
more than 5 days have passed, and the temperature hasn't dropped back down again).
After being on 67.5 mcg for about 3 weeks, she again has some trouble getting
her doses on time, and her temperature slips a little and some of her symptoms
return. She improves a little with a T4 test dose but not as well as before,
and no further improvement is obtained when the T4 test dose is repeated in
1 and 1/2 hours. Her temperature is raised back to normal when her dose is increased
to 75 mcg BID, but she still is not feeling as well as she had been previously
on 67.5 mcg BID.
It is determined that it would be best to wean her off the present cycle in
favor of the next cycle, and she begins to wean off the medicine by 7.5 mcg
decrements every 2 days. Her temperature starts to slip, so her wean is decelerated
to one decrement in her dose every 4 days, which works out well.
After remaining off T3 for 3 days between cycles, she begins the second cycle.
She is able to capture her temperature on 30 mcg BID this time. She now feels
what she considers to be 80% normal. She is satisfied for now and would like
to stay on this dose for a month or so, because she has some stressful weeks
coming up and doesn't want to take the time to change her dosing, or take the
chance of not feeling as well.
Two months later she weans off the 2nd cycle as she did the first, and 3 days
later begins the 3rd. She captures her temperature on 15 mcg BID, and feels
now what she considers 100% normal. After a couple of months she weans off the
treatment and remains well off therapy.
Three months down the road, she makes a stressful presentation, and notices
herself starting to slip clinically, over the next several days. Her temperature
has slipped as well. She finds that she is able to get her temperature back
up on only 7.5 mcg BID, which she discontinues successfully after about a week.
She now uses small doses of T3 to quickly catch relapses. She has even noticed
that if she takes 7.5 mcg BID the day before, the day of, and the day after
a presentation she knows will be stressful (and would typically cause a mild
relapse for her) she can often prevent the relapse from occurring at all.

The patient is a 45 y.o woman who is complaining of severe fatigue, headaches,
depression, decreased memory, irritability, and easy weight gain. Her symptoms
first appeared 10 years ago after the birth of her second child. Her symptoms
tend to worsen each time she goes on a strict diet to lose weight (she often
gains the weight back, and then some). They did seem to improve somewhat when
she was treated on a clinical basis with some thyroid medicine for several months
about 4 years ago. But she moved to another state, and could not find a doctor
who would treat her with thyroid medicine, since her tests were normal.
Upon evaluation it was determined that her temperature averaged 97.3 during
the day, and her blood tests were normal. Also, her EKG revealed her heart rate
to be very slightly irregularly irregular. So slightly that most doctors would
probably say that she had normal sinus rhythm. In the history she admitted to
having noticed some skipped beats from time to time. She was counseled that
she had a higher than normal risk of having cardiovascular side effects such
as palpitations, skipped beats, or increased heart rate ( p71).
But all involved felt her potential benefit outweighed her risks.
She is started on 7.5 mcg p.o. BID and is instructed to increase the dose by
7.5 mcg/dose/day if she is without complaints until her temperature is 98.6
by mouth on average (or until she is up to 90 mcg BID), and to call the office
if she develops any complaints, and to return to the office in 2 weeks. Her
temperature first reaches normal on 15 mcg BID. Six days later it drops back
down again. Her dose is increased to 22.5 mcg and then the next day to 30 mcg
BID, which brings her temperature back up to normal. About 6 days later her
temperature drops back down again, and her dose is increased again. Finally,
her temperature is captured on 60 mcg BID. She feels very well. In fact, she
is incredulous that she can feel so well after so many years of feeling so badly,
and especially that the treatment was so simple. She finds it hard to believe/understand
that this treatment wasn't thought of sooner.
She stays on 60 mcg BID for almost 3 months before wanting to proceed with
the treatment's course. She has not had any complaints on the T3 therapy. Unfortunately,
she misunderstood or forgot the instructions and weaned off the T3 therapy by
7.5 mcg/dose/day in spite of the fact that her temperature dropped after the
third decrease. Some of her symptoms returned as she weaned off, and she was
discouraged. It was explained to her how she should have weaned off more slowly,
to give her own system a chance to come up and maintain her temperature.
She was started on a second cycle and was able to capture her temperature on
52.5 mcg BID (when she might have been able to on much less had she not squandered
so much of the benefit from the first cycle by weaning off too quickly). After
a month or so on that dose, she was ready to try weaning off again. This time,
she began by decreasing the dose by 7.5 mcg/dose/2 days. However, when her temperature
started to slip on the second decrease, she went back up an increment (since
there was a good chance this could be her final cycle), and then decelerated
the wean to 7.5 mcg/dose/4 days. After a couple of decreases, her temperature
started to slip again, so she went back up an increment and decelerated the
wean to 7.5 mcg/dose/6 days. She was then able to continue weaning off the T3
until she was off completely, and her temperature remained normal off the treatment.
She did very well for over a year, until her sister died in a car accident.
Her temperature dropped and her symptoms began to return. She was started back
on a cycle of T3 and after about one week, she was able to capture her temperature
on 22.5 mcg BID. She stayed on that dose for about 2 months and then was able
to wean off the T3 therapy again, without any difficulty in maintaining her
body temperature on her own.
