Eltroxin side effects

In July/August 2007 GSK changed the formulation of the standard Thyroid medication Eltroxin.  Some patients were informed - and told it was exactly the same so no need to be concerned. Sadly, the majority of users were not informed!
It took many months for people to understand that their worsening symptoms were caused by the changed medication!
