My Dr Wants To Change Me From Methotrexate To Humira

My Dr wants to change me from methotrexate to Humira for my RA. He first wanted xeljanz but my med plan won't go for it. Part of the reason for the change is my almost continuous shingles. I have been on Celebrex for 10 years and methotrexate for about 6 years. I am concerned by the info that says my immune system may be more compromised with the Humira. Is that true?
