My chemist hasn't got Accord Levothyroxine, so it's a choice of Mercury or Northstar, any advice please?

Northstar is the same as Accord - it's made by the same people, just rebranded for Lloyds Pharmacy (also rebranded as Almus for Boots). But that only applies to the 100mcg and 50mcg Northstar tablets, the 25mcg Northstar are made by Teva.

So if you're happy on Accord and you have the 100 or 50mcg then you can have the Northstar of the same doses.

Thanks, I'll take your advice.

Not sure about Northstar, but had Mercury before now with no problems. I have Morningside mostly and occasionally Accord. It is all down to price with these pharmacists. If you live in the UK, I would change your pharmacist and go to Boots. We have a brilliant relationship with our branch, so very helpful and friendly.

Hi, that last ones l got we’re Mercury l diddnt think they were any good!!stopped using!!

You just might recognise the product if you look through this document. Miles from complete but there is a possibility...

I do wonder sometimes how people know. I never feel brilliant so not sure whether I'd notice. Only became aware with the comments here.

I found out how much difference they make when I was given a different make and slowly but steadily went downhill.

If you keep switching round, it might be very difficult to identify the issue.

I have created, and try to maintain, a document containing details of all thyroid hormone medicines in the UK and, in less detail, around the world.

During lockdown my pharmacy changed to Teva brand. I’ve slowly come to realise that I feel less well on it. Thanks for the info, I’ll change pharmacy to Boots.

The company that I get my Levo from is TEVO and it is working just fine!

The branding is TEVA.

The problem is that some people who take Teva levothyroxine do very badly. At the same time, some do very well. It isn't a simple situation in which Teva is always a problem.
