Rituxan (rituximab) carries several serious FDA boxed warnings, including for fatal infusion reactions, severe mucocutaneous reactions, Hepatitis B virus reactivation, and Progressive Multifocal Leukoencephalopathy (PML). Understanding **how toxic is Rituxan** is critical for patients and healthcare providers to manage risks and ensure safe treatment.

While initially developed for cancer treatment, rituximab has demonstrated varied levels of efficacy across numerous autoimmune diseases. The overall response rate (complete and partial) can be high, with one registry study showing an 86.7% response across various conditions, but success rates of **rituximab infusion for autoimmune disease** depend heavily on the specific disorder.

While Rituxan (rituximab) can be an effective treatment for a range of conditions, it is known to carry risks, and reports of severe kidney problems, sometimes fatal, have been documented, especially in patients with Non-Hodgkin’s Lymphoma.

The FDA has issued multiple serious, or 'boxed', warnings for rituximab due to significant adverse event reports. The most important safety information includes risks of fatal infusion reactions, progressive multifocal leukoencephalopathy (PML), and hepatitis B virus (HBV) reactivation.

Infusion-related reactions are a very common side effect of rituximab, with some studies showing up to 77% of patients experiencing a reaction during their first infusion. This article explores the question, 'What are the most common adverse effects of rituximab?'.
