Sorry, my experience with infusions started in April with Rituxan (2 infusions, 2 weeks apart and repeating in 6 months and almost always done with a methotrexate regimen) and we are starting to schedule the next pair of infusions)

Love it. Worked miracles with no side effects. Gave me my life back. Very little pain and pretty much fully functional.

I was on Remicade for about 6 years, with hardly any side effects, then I started to have reactions, and it just stopped being effective. As most do after a time. It really depends on the individual. Everyone's body is different. Good Luck. I hope it helps relieve your RA symptoms.
Blessings to you and yours
