Hi,
In France since March 2017, Merck labs have modified the ingredients of Levothyrox, a treatment given to patients with thyroide problems.
I have been given this new treatment and I am suffering from vertigo, change of humeur, tiredness etc;
There is a huge petition in France to get this drug changed back to its previous formula.
No one was informed about this change.
Its the biggest drug sold for over 1 million people in France.
Do you think that maybe yours could have been changed too in the UK?
