thank you for your question. I have been on Entyvio since 2016 and absolutely love it (as much as one can love a biologic!). It has put me in remission, and I have not had any negative side effects, unlike I had with previous biologics. The only initial side effect I had was that after my first two doses, I was extremely fatigued for the next 48 hours but that stopped after my ramp up doses.
While it is an infusion, which is not as convenient as administering a simple syringe like with Humira or Stelara, I have found that the 30 minute infusion is not bad and goes rather quickly.
I hope this helps provide you with some insight to help in making your decision!
