I have been on humira injections every two weeks for 10 years. It has been life changing and stopped the development of the disease. My doctor has said I will shortly be asked if I would like to be transferred to a new Biosimilar drug. Has anyone transferred to a Biosimilar? If so was there any difference in effect - I have never had any side effects on Humira and am very happy with it but realise it is expensive and if an use a Biosimilar it will save the Health Service quite a lot of money. Any comments please?
