Some Dr prefer one biologic over another. Some pick because of other conditions, IBD or psoriasis are reasons to pick a particular biologic. I was given the choice of Remicade or Humira because they both are supposed to help with IBD and I have UC. It's nice if one med can treat two or more conditions at the same time.

Cherish your yesterdays,
Dream your tomorrows,
But live your todays.
Do the very best you can
leave the rest to God.
God Bless,
