What is ocrelizumab?
Ocrelizumab is a monoclonal antibody that affects the actions of the body's immune system. Monoclonal antibodies are made to target and destroy only certain cells in the body. This may help to protect healthy cells from damage.
Ocrelizumab is used to treat multiple sclerosis (relapsing or progressive forms).
Ocrelizumab may also be used for purposes not listed in this medication guide.
Ocrelizumab may cause unpleasant side effects while the medicine is injected, or up to 24 hours later. Tell your caregivers right away if you have any unusual discomfort during the injection.
Before taking this medicine
You should not be treated with ocrelizumab if you are allergic to it, or if you have:
active infection with hepatitis B.
Tell your doctor if you have received any vaccine within the past 6 weeks.
To make sure ocrelizumab is safe for you, tell your doctor if you have:
any type of active infection;
a history of using medicine that can weaken your immune system;
if you are a carrier of hepatitis B; or
if you are scheduled to receive any vaccines.
Using ocrelizumab may increase your risk of developing certain types of cancer, such as breast cancer. Ask your doctor about your specific risk.
It is not known whether ocrelizumab will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant. Use effective birth control to prevent pregnancy while you are using this medicine and for at least 6 months after your last dose.
It is not known whether ocrelizumab passes into breast milk or if it could affect the nursing baby. Tell your doctor if you are breast-feeding.
How is ocrelizumab given?
Before you start treatment with ocrelizumab, your doctor may perform tests to make sure you do not have hepatitis B or other infections.
Ocrelizumab is injected into a vein through an IV. A healthcare provider will give you this injection.
You may be given other medications to prevent certain side effects of ocrelizumab.
Your first dose of ocrelizumab will be split into 2 separate infusions. You will receive these infusions 2 weeks apart. The following doses will be given once every 6 months.
Ocrelizumab must be given slowly and each infusion can take up to 3 hours and 30 minutes to complete.
You will be watched closely for at least 1 hour after receiving ocrelizumab, to make sure you do not have an allergic reaction to the medication.
If you have ever had hepatitis B, ocrelizumab can cause this condition to come back or get worse. You will need frequent blood tests to check your liver function during treatment and for several months after you stop using this medicine.
What happens if I miss a dose?
Call your doctor for instructions if you miss a dose of ocrelizumab.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while receiving ocrelizumab?
Do not receive a "live" vaccine while using ocrelizumab, or you could develop a serious infection. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.
