My chemist has a note to give me the same brand each time. I'm not sure whether I felt any different on different brands, but had read advice here to stick to the same one.


When I started on levothyroxine, I was determined that I would be able to handle all makes without any problems.

First off, Teva managed to fail to deliver its claimed dose. It wasn't me that realised this - but the MHRA and others.

Then I found that Mercury Pharma and Actavis were different for me. Even combining one of each didn't quite work right. So now I absolutely agree that we should stick to one make whenever possible.
