How long after treatment with rituxan (rituximab) will side effects go away?

What SE? What side effects (from rituximab)? About 25% of people will have an "infusion reaction" on initial dose with possible hives, shortness of breath, shaking, etc. That is usually not a condition that persists after the infusion is completed. Other side effects can come from killing cancer cells quickly such as tumor lysis syndrome, or some more rare long term Rituximab side effects?
