Hi, I have infusions of Rituxan approximately every 4 months. The first infusion is 5 hours followed by part 2 in 14 days. Subsequent infusion time is more like 3.5 hours.
I typically have a headache for 12 hours and a steroid high from the required depomedrol injection.
But Rituxan is the only drug that seems to be effective for me. So it's fine.
Good luck and keep trying until you find a better solution.
