liothyronine vs liothyroxine?

I have just collected my prescription from the pharmacy. I take 20mcg tablets of Liothyroxine and 74 of Levothyroxine daily.

The pharmacy has supplied me with 20mcg Liothyronine by Roma.

Is there any difference between Liothyroxine and Liothyronine?

Many thanks in advance. X

mantras, Liothyronine is t3. Liothyroxine is a mis-word. You have been mistaken in thinking that was what t3 was called.

thankyou. I will now phone and apologise to pharmacist. I fell off my perch as it was a different brand and a bigger box … clearly hadn’t paid attention before. Ah well x

Liothyroxine - is this a mix of levo & lio - what is the brand? If I search for it - I can find a reference.  

Can you check spelling & add brand. Are they dispensed in separate bottle? (Pharmacist may have put incorrect spelling on label)   I’ve recently had a medicine with error printed on instructions- “adn” hand crossed out and corrected to and. 

 A manufactures patient information leaflet  should always be supplied.  

I’ve heard of Liothyronine by Roma. (LT3) 

How much levothyoxine to you take 75mcg?  Or are a quantity of 74 pills being dispensed, for month?

nope I just got confused so it’s my not reading earlier boxes that’s the problem.

I think this is a simple mistake. I saw a clinician had written levothyronine on a blood test request form the other day. There's no such thing as levothyronine or liothyroxine.

T3 is liothyronine

T4 is levothyroxine

There are even research papers which got the name wrong!

I suspect that it is most often a typo which never got corrected.

One of the hits is to Effects of L-Thyroxine and Liothyroxine on Spermatogenesis.

But if you find that actual paper, from 1958, its heading is correct and it uses the work Liothyronine. So I suspect Optical Character Recognition made a mistake.

Do you normally split your T3 as 2 or 3 smaller doses spread through the day

Capsules can’t be split …..

It’s a cost issue - see post here discussing prices
