How long does it usually take for rituximab to work?
Rituximab typically takes several days to weeks to improve AIHA symptoms. This is notably longer than some emergency treatments like IVIG, which can begin working in one to five days.
The timeline can vary from person to person, but rituximab works by targeting the white blood cells (B cells) that create the autoantibodies responsible for destroying red blood cells. This process takes time to show measurable improvement in your symptoms.
If you're experiencing severe hemolysis and need faster relief, your healthcare provider might consider IVIG or other emergency treatments while waiting for rituximab to take effect. It's important to stay in close contact with your hematologist during this period to monitor your progress.
