Hi allI have just had my 3rd injection of Tyenne Biosimilar after being on Tocilizimab since approx 2019.
My skin has become much more sensitive in the last couple of weeks. I have had a rash on my neck and chest, and now my arms. I also have been feeling prickly on my head and getting hotter than normal in the sun.
With Tocilizimab I knew to be careful of sun sensitivity, using sun screen, a hat and covering up. I didn't have any major skin reactions, unlike previous biologics Enbrel, Humira which I couldn't continue because of skin reactions.
So I am now wondering if this change to Tyenne is causing an allergic reaction/side effect.
I have read that others have found a change to a Biosimilar can cause problems.
What are my chances of getting changed back to Tocilizimab I wonder now that my NHS Trust have made this switch. It seems a coincidence for this to happen suddenly on the different drug. Feeling fed up, I was doing so well on Tocilizimab. Thanks for any thoughts. 😊
