Important Safety Information

What is the most important information I should know about OCREVUS?

OCREVUS can cause serious side effects, including:

• Infusion reactions: OCREVUS can cause infusion reactions that can be serious and require you to be hospitalized. You will be monitored during your infusion and for at least 1 hour after each infusion of OCREVUS for signs and symptoms of an infusion reaction. Tell your healthcare provider or nurse if you get any of these symptoms:
  • itchy skin
  • rash
  • hives
  • tiredness
  • coughing or wheezing
  • trouble breathing
  • throat irritation or pain
  • feeling faint
  • fever
  • redness on your face (flushing)
  • nausea
  • headache
  • swelling of the throat
  • dizziness
  • shortness of breath
  • fatigue
  • fast heart beat
  These infusion reactions can happen for up to 24 hours after your infusion. It is important that you call your healthcare provider right away if you get any of the signs or symptoms listed above after each infusion.
  If you get infusion reactions, your healthcare provider may need to stop or slow down the rate of your infusion.
• Infection:
• OCREVUS increases your risk of getting upper respiratory tract infections, lower respiratory tract infections, skin infections, and herpes infections. Tell your healthcare provider if you have an infection or have any of the following signs of infection including fever, chills, a cough that does not go away, or signs of herpes (such as cold sores, shingles, or genital sores). These signs can happen during treatment or after you have received your last dose of OCREVUS. If you have an active infection, your healthcare provider should delay your treatment with OCREVUS until your infection is gone.
• Progressive Multifocal Leukoencephalopathy (PML): Although no cases have been seen with OCREVUS treatment, PML may happen with OCREVUS. PML is a rare brain infection that usually leads to death or severe disability. Tell your healthcare provider right away if you have any new or worsening neurologic signs or symptoms. These may include problems with thinking, balance, eyesight, weakness on 1 side of your body, strength, or using your arms or legs.
• Hepatitis B virus (HBV) reactivation: Before starting treatment with OCREVUS, your healthcare provider will do blood tests to check for hepatitis B viral infection. If you have ever had hepatitis B virus infection, the hepatitis B virus may become active again during or after treatment with OCREVUS. Hepatitis B virus becoming active again (called reactivation) may cause serious liver problems including liver failure or death. Your healthcare provider will monitor you if you are at risk for hepatitis B virus reactivation during treatment and after you stop receiving OCREVUS.
• Weakened immune system: OCREVUS taken before or after other medicines that weaken the immune system could increase your risk of getting infections.

Before receiving OCREVUS, tell your healthcare provider about all of your medical conditions, including if you:

• have ever taken, take, or plan to take medicines that affect your immune system, or other treatments for MS.
• have ever had hepatitis B or are a carrier of the hepatitis B virus.
• have had a recent vaccination or are scheduled to receive any vaccinations. You should receive any required vaccines at least 6 weeks before you start treatment with OCREVUS. You should not receive certain vaccines (called ‘live’ or ‘live attenuated’ vaccines) while you are being treated with OCREVUS and until your healthcare provider tells you that your immune system is no longer weakened.
• are pregnant, think that you might be pregnant, or plan to become pregnant. It is not known if OCREVUS will harm your unborn baby. You should use birth control (contraception) during treatment with OCREVUS and for 6 months after your last infusion of OCREVUS.
• are breastfeeding or plan to breastfeed. It is not known if OCREVUS passes into your breast milk. Talk to your healthcare provider about the best way to feed your baby if you take OCREVUS.
