RE: T3 and T4 dosage

[Guest guest]

Hi

Sharon

When starting a patient on Liothyronine (T3) the doctor usually

drops the dosage for thyroxine - by either 25mcgs or 50mcgs. Did your GP do

that. Your daughter should take her two three in two split doses. Take the

first dose when she wakes, and the second dose about 3.00p.m. This is because

the T3 has a very short half life and leaves the body after about 6 to 8 hours,

so about that time in the afternoon, her morning dose will be starting to

disappear. The T3 is the active hormone. She can keep increasing it by 10mcgs

until her symptoms start to disappear but if ever she reaches a stage where a

couple of hours after she has taken her morning dose, she feels dizzy, sweaty,

spaced out and generally awful, this is usually a sign she is taking too much.

Don't worry, because this feeling will leave her after a couple of hours or so,

but tell her not to take any more that day. The following day, she starts back

on the dose she was on before her latest increase. Sometimes, stopping the T3

for a day helps and then starting back again is fine.

Even at 17 your daughter could well have adrenal problems,

especially if she has suffered either physical or emotional stress. If the T3

doesn't start to work properly, it will be because of her adrenals, and she

should think about getting tested.

However, ask her to ask her GP to test her ferritin, B12,

vitamin D3, magnesium, zinc, copper and folate, because if they are low, she

will not be able to absorb the thyroid hormone.

Hope this will work out fine for her Sharon.

Just taken my daughter to the doctors and he has prescribed T3,HOORAY!!! The

silly endo she last saw said she didnt have an underactive thyroid,but she

should increase her levo from 75 to 100mcg straight away! She did this,but

started getting headaches,so I told her to reduce it back to 75mcg to see if

it helps and the headaches stopped.She has many hypo symptoms,not really

relieved by levo and some are getting worse,so I asked our GP to prescribe T3

as I thought this would be the next step for my daughter.At 17,I wouldnt have

thought that she would have a problem with adrenal fatigue,but Im no

specialist,so am just guessing.There is plenty of room for her TSH/T4 andT3

levels to improve,but as she is not responding to T4 alone,this is why I

suggested T3.He has started her on a dose of 20mcg a day and wants to see her

in 3 weeks to increase it,but I dont know what the protocol is for dosing

with T3.Does she have to take the T3 at the same time as her T4 or seperately

from it and I know the dose has to be split but how far apart and how far

away from vits and minerals too.My GP has admitted that he has no knowledge

of T3 dosage or treatment and even had to look up T3 in an old book he had!

Do you think I made the right decision for my daughter in asking for T3 to be

the next step forward? Its very difficult to make a decision on someone elses

behalf when you dont know what to do,especially when your GP knows nothing!

Hope you can help with my questions and advice me as to what to do next.

Best wishes Sharon

Hi Sharon, Hmm! In your shoes I'd try 10mcg twice a day, and if her heart rate rises too much cut back by a half until it settles, then try again. 75mcg T4 isn't really much so I wouldn't stop that, but consider doing that if she seems to overreact to the T3. If she does go hyper ( she probably won't) then no thyroid meds until it settles- T3 is out of the body fast so she'll feel better next day. T3 can really be a magic pill. I got headaches too on t4. Keep thyroid meds 4 hours away from calcium ( incl milk) and iron sheila@...My GP has admitted that he has no knowledge of T3 dosage or treatment and even had to look up T3 in an old book he had!
