Yes - infused but it's a short infusion (we were told 1 hour, but my daughter still goes to a children's hospital, so it may be faster for adults). The loading doses are the same as Remicade - at 0 weeks, 2 weeks and 6 weeks. Then every 8 weeks after that.
My daughter is starting Entyvio on Monday.
It takes time for Entyvio to work - we were told peak efficacy is between 14 and 22 weeks, so it's not quick like Remicade. Most people need to be steroids until it starts working.
The results for Crohn's are not as good as UC, but if you've failed everything else, it's worth a shot.
