Important Safety Information
Rituxan can cause serious side effects that can lead to death, including:
- Infusion Reactions: Infusion reactions are very common side effects of Rituxan treatment. Serious infusion reactions can happen during or within 24 hours of the infusion. The patient’s healthcare provider should give the patient medicines before their infusion of Rituxan
- Severe Skin and Mouth Reactions: The following symptoms can occur during treatment with Rituxan: painful sores or ulcers on the skin, lips, or in the mouth; blisters; peeling skin; rash; or pustules
- Hepatitis B Virus (HBV) Reactivation: If patients have had hepatitis B or are carriers of hepatitis B virus, receiving Rituxan could cause the virus to become an active infection again. Hepatitis B reactivation may cause serious liver problems, including liver failure and death. Patients should not receive Rituxan if they have active hepatitis B liver disease. The patient’s healthcare provider will monitor the patient for hepatitis B infection during and for several months following their treatment
- Progressive Multifocal Leukoencephalopathy (PML): PML is a rare, serious brain infection caused by a virus that can happen in people who receive Rituxan. People with weakened immune systems can get PML. PML can result in death or severe disability. There is no known treatment, prevention, or cure for PML
Before receiving Rituxan, patients should tell their healthcare provider if they:
- have had a severe infusion reaction to Rituxan in the past
- currently have or have a history of other medical conditions, especially heart disease
- have had a severe infection, currently have an infection, or have a weakened immune system
- have had a recent vaccination or are scheduled to receive vaccinations

What are the possible side effects of Rituxan?
Rituxan can cause serious and life‐threatening side effects, including:
- Tumor Lysis Syndrome (TLS): TLS is caused by the fast breakdown of cancer cells. TLS can cause kidney failure and the need for dialysis treatment, or an abnormal heart rhythm
- Serious Infections: Serious infections can happen during and after treatment with Rituxan and can lead to death. Rituxan can increase the risk of getting infections and can lower the ability of the patient’s immune system to fight infections. People with serious infections should not receive Rituxan
- Heart Problems: Rituxan may cause chest pain, irregular heartbeats, and heart attack. The patient’s healthcare provider may monitor the patient during and after treatment with Rituxan if they have symptoms of heart problems or have a history of heart problems
- Kidney Problems: especially if a patient is receiving Rituxan for non–Hodgkin’s lymphoma (NHL). The patient’s doctor should do blood tests to check how well the patient’s kidneys are working
