Safety & side effects

Most important side effect information for GAZYVA

Hepatitis B can cause liver failure and death. If you have a history of hepatitis B infection, GAZYVA could cause it to return. You should not receive GAZYVA if you have active hepatitis B liver disease. Your doctor or healthcare team will need to screen you for hepatitis B before, and monitor you during and after, your treatment with GAZYVA. Sometimes this will require treatment for hepatitis B. Symptoms of hepatitis B include worsening of fatigue and yellow discoloration of skin or eyes

PML is a rare and serious brain infection caused by a virus. PML can be fatal. Your weakened immune system could put you at risk. Your doctor will watch for symptoms. Symptoms of PML include confusion, difficulty talking or walking, dizziness or loss of balance, and vision problems

Additional possible serious side effects of GAZYVA

These side effects may occur during or within 24 hours of any GAZYVA infusion. Some IRRs can be serious, including, but not limited to, severe allergic reactions (anaphylaxis), acute life-threatening breathing problems, or other life-threatening IRRs. If you have a reaction, the infusion is either slowed or stopped until your symptoms are resolved. Most patients are able to complete infusions and receive medication again. However, if the infusion-related reaction is life-threatening, the infusion of GAZYVA will be permanently stopped. Your healthcare team will take steps to help lessen any side effects you may have to the infusion process. You may be given medicines to take before each GAZYVA treatment. Symptoms of IRRs may include fast heartbeat, tiredness, dizziness, headache, redness of the face, nausea, chills, fever, vomiting, diarrhea, rash, high blood pressure, low blood pressure, difficulty breathing, and chest discomfort

Some people receiving GAZYVA may have severe or life-threatening allergic reactions. This reaction may be severe, may happen during or after an infusion, and may affect many areas of the body. If an allergic reaction occurs, your doctor will stop the infusion and permanently discontinue GAZYVA

While you’re taking GAZYVA, you may develop infections. Some of these infections can be fatal and severe, so be sure to talk to your doctor if you think you have an infection. Patients with a history of recurring or chronic infections may be at an increased risk of infection. Patients with an active infection should not be treated with GAZYVA. Patients taking GAZYVA plus standard therapy may be at higher risk for fatal or severe infections compared to patients taking standard therapy plus placebo. If you develop a serious infection, your doctor will immediately discontinue GAZYVA and begin treatment for the infection

When you have an abnormally low count of infection-fighting white blood cells, it is called neutropenia. While you are taking GAZYVA, your doctor will do blood work to check your white blood cell count. Severe and life-threatening neutropenia can develop during or after treatment with GAZYVA. Some cases of neutropenia can last for more than one month. If your white blood cell count is low, your doctor may prescribe medication to help prevent infections

Platelets help stop bleeding or blood loss. GAZYVA with chemotherapy may reduce the number of platelets you have in your blood; having low platelet count is called thrombocytopenia. This may affect the clotting process. While you are taking GAZYVA, your doctor will do blood work to check your platelet count. Severe and life-threatening thrombocytopenia can develop during treatment with GAZYVA. Fatal bleeding events have occurred in patients treated with GAZYVA. If your platelet count gets too low, your treatment may be delayed or reduced

Fatal and severe DIC has been reported in people receiving GAZYVA for chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL). DIC is a rare and serious abnormal blood clotting condition that should be monitored and managed by your doctor, as it can lead to uncontrollable bleeding

Most common side effects of GAZYVA

The most common side effects that occurred in 5% or more of patients who received GAZYVA plus standard therapy for lupus nephritis were upper respiratory tract infection, COVID-19, urinary tract infection, bronchitis, pneumonia, infusion-related reactions, and low white blood cell count (also known as neutropenia).

Do NOT receive GAZYVA if you have had an allergic reaction (eg, anaphylaxis or serum sickness) to GAZYVA. Tell your healthcare provider if you have had an allergic reaction to obinutuzumab or any other ingredients in GAZYVA in the past.
