Taking Tyroxine At Night

[Sammy48]

my sister always takes her Thyroxine in the morning about 6 ish, though always feels low energy until around 3 ish. Other thyroid sufferers have told her that by swapping to taking it Kate in the evening, it has mad a great difference to how they feel, more energy in morning etc.

Anyone had any experience of this ?

[Sammy48]

^^^late that should say not Kate ^^^^

It doesn't matter a jot when you take it.

[Sammy48]

So you are saying it makes no difference to how you feel. Her friend's Endo said its better absorbed at night and the only reason it's told to take in morning is so patients don't forget it,

[Sqad]

You seem to have an idea of the answer as suggested by your friend's Endo........I assume that means Endocrinologist.
That is HIS opinion and i have given mine........they seem to differ.

\\\\\So you are saying it makes no difference to how you feel.\\\

Yes...that is exactly what i am saying.......if your friend has fluctuating symptoms during different parts of the day, they have nothing to do with the time of day that she takes her thyroxine.

I agree with Dr Sqad. I take mine in the morning and it makes no difference to my day.. high/lows.. whatever. The reason I take mine in the morning is because that's what the prescription states.

[Sammy48]

Think my sister is going to give it a go at night.

Then why bother asking?

[Clanad]

In supporting Sqad's declarative phrase… those of us that take a thyroid replacement (i'm in the U.S.) are required to return to our physician periodically (maybe once every six months) to have a blood test to determine the TSH levels, including T3 and T4. If a change in the prescription strength is indicated, another test will be conducted within a few weeks to determine, again, the levels. This indicates and is supported by statements from the Doctor that it takes a while for the levels to change… therefore any change in the time of day for taking the script makes no difference at all...

[Sqad]

\\\\\ therefore any change in the time of day for taking the script makes no difference at all...\\\

Clanad is correct plus the half life of thyroxine is about 10 days ( in simple terms if one stopped taking thyroxine now, in 10 days time there would still be half the dose left in the blood)
The biological effect ( that is how long one still feels fine following stopping the drug) is in weeks, making what part of the day one takes it, unimportant.

[Sammy48]

Maclarencat. Well I am asking to get different opinions, the site is called Answerbank or haven't you noticed.

[Sammy48]

Clanad thanks for the information.

Sqad my sister doesn't have a thyroid it was removed 5 years ago approx. does the thyroxine staying in her system still apply. ?

[Sammy48]

Just out if interest Sqad, when do you take your thyroxine and do you take on an empty stomach ? Sorry for being nosy.

[Sqad]

LOL....not nosey at all.....I take mine in the morning before breakfast.

[Sqad]

\\\\\Sqad my sister doesn't have a thyroid it was removed 5 years ago approx. does the thyroxine staying in her system still apply. ?\\\

Yes....it does still apply.

[Sammy48]

Sqad, so trying the thyroxine at night won't do any harm?

She feels so low of a morning and after speaking to other sufferers on Thyroid UK who have successfully changed, thought she would give it a go. I said let me ask our resident doc on AB for his opinion.

[Sqad]

No it won't do any harm and who knows, it might solve her problem....;-)

[Sammy48]

Thank you so much, Saad. xx
