Mercurypharma v Teva thyroxine

[haggisplant]

Hi I’ve been switched from MP to Teva 25, my 100s are still Almus.

Prior to the Teva crap 6 years ago I would t have given two hoots but I was on the batch that was the problem in early pregnancy and it caused a lot of problems. My son is fine but it was extremely stressful trying to get the tsh right and there were definitely negative impacts that continued for a long time.

It’s only 25 and I know testing is more rigorous but just wondered if there’s any current known differences?

No other intolerances.

Teva was reformulated to be lactose free. Instead of lactose they now use Mannitol.

Many, many members report reacting badly to this new formulation. It does, however, suit some people.

Ok thanks, what’s the reaction? I was thinking more about the strength but probably a silly question.

what’s the reaction?

Various adverse reactions/side effects. Lots of posts if you want to read through them

I don't think strength comes into it, they're all formulated to be the same strength with a certain tolerance +/-

I know there is a lot of hype about Teva but I prefer it as it’s the only one I stay awake on and I feel it’s the only one my body processes and converts well. It is reformulated so a lot of misinformation is from prior to this. If you look up the ingredients you will find mp and Teva are exactly the same except Teva do not contain lactose. The formulation of mp and Teva is different from others as they have different fillers making these 2 stand alone from other makes. Hope this helps.

I think you will find that Teva levothyroxine also contains Microcrystalline Cellulose.

We also have the difficulty in comparing products that even when ingredients appear the same (that is, they have the same name), we as poorly-informed outsiders are not in a position to assess whether or not they are identical.

(Ironically, it was almost exactly this issue which resulted in the "old formula" Teva being withdrawn. They used a different form of dextrin which had different properties without both adequate testing AND getting permission/approval for that change.)

Could a hive like rash be attributed to the Teva? I just worked out I’ve had one since I started this new pack.
