Hello HaoKang The Oncologist may switch you to another biologic or add another type of RA drug, like methotrexate or sulfasalazine, so your treatment works better.
You must communicate w the Oncologist, you want to be more included in the treatment plain. So you know the options.
Nothing is worse than not knowing. 🙏🏻
