Before Using This Medicine

Interactions with Medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur.

Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.
Interactions with Food/Tobacco/Alcohol
Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.

Proper Use of This Medicine

Ocrelizumab needs to be given on a fixed schedule. If you miss a dose, call your doctor for instructions.
Ocrelizumab should come with a Medication Guide. Read and follow the instructions carefully. Ask your doctor if you have any questions.
Precautions While Using This Medicine
It is very important that your doctor check you at regular visits to make sure ocrelizumab is working properly. Blood tests may be needed to check for any unwanted effects.
Ocrelizumab may cause a rare but serious type of an allergic reaction called an infusion reaction. This can be life-threatening and require immediate medical attention. Tell your doctor right away if you start to have cough, difficulty with swallowing, dizziness, fast heartbeat, trouble with breathing, chest tightness, swelling in your face or hands, fever, chills, itching or hives, or lightheadedness or faintness while you are receiving ocrelizumab.
Ocrelizumab may increase your risk of developing infections, including a serious brain infection called progressive multifocal leukoencephalopathy. Avoid being near people who are sick or have infections while you are using ocrelizumab. Wash your hands often. Also tell your doctor if you have ever had an infection that would not go away or an infection that kept coming back.
While you are being treated with ocrelizumab, and after you stop treatment with it, do not have any immunizations (vaccinations) without your doctor's approval. You should receive live vaccines for at least 6 weeks before starting treatment with ocrelizumab. Ocrelizumab may lower your body's resistance and there is a chance you might get the infection the immunization is meant to prevent. In addition, other persons living in your household should not take oral polio vaccine since there is a chance they could pass the polio virus on to you. Also, avoid persons who have taken oral polio vaccine within the last several months. Do not get close to them, and do not stay in the same room with them for very long. If you cannot take these precautions, you should consider wearing a protective face mask that covers the nose and mouth.
Using ocrelizumab may increase your risk of getting cancer (including breast cancer). Talk to your doctor if you have concerns about this risk.
It is important to tell your doctor if you are pregnant or planning to become pregnant. Use effective birth control during treatment and for 6 months after your treatment ends.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
