What Ocrelizumab is used for
Ocrelizumab is a specialized medicine primarily used to treat certain conditions affecting the nervous system, which can sometimes impact eye health. At Pristine Eye Hospitals, our specialists may recommend Ocrelizumab for:
- Multiple sclerosis (MS)
- Optic neuritis related to multiple sclerosis
Multiple sclerosis is a chronic disease that affects the brain and spinal cord. It can lead to a range of symptoms, including problems with vision, balance, and muscle control. Optic neuritis is an inflammation of the optic nerve, which carries visual information from the eye to the brain. When optic neuritis occurs as part of MS, it can cause pain and temporary vision loss in one eye.
Our team of neuro-ophthalmology specialists will carefully assess your condition to determine if Ocrelizumab is the right treatment option for you, ensuring it aligns with your specific needs and medical history.
How it works
Ocrelizumab works by targeting and reducing the number of specific immune cells in your body called CD20 B cells. These B cells are believed to play a significant role in the inflammation and damage that occurs in multiple sclerosis. By depleting these cells, Ocrelizumab helps to reduce the activity of MS, which can help manage symptoms and slow the progression of the disease, including its impact on your vision through conditions like optic neuritis.
This mechanism helps to calm the immune system’s attack on the body’s own tissues, particularly in the brain and spinal cord, thereby reducing the frequency and severity of MS relapses and potentially slowing disability progression. Our doctors will explain this process in more detail and how it specifically benefits your condition.
How it’s used
Ocrelizumab is administered as an intravenous (IV) infusion, which means the medicine is given directly into your vein through a drip. This procedure is always performed in a hospital or clinic setting by trained healthcare professionals, under the direct supervision of a specialist doctor.
The typical dosing schedule for Ocrelizumab is once every six months. Your doctor will determine the exact strength of the infusion (either 300 mg or 600 mg) based on your specific treatment plan and medical condition. It is crucial to attend all your scheduled infusion appointments to ensure the medicine works effectively and to allow for continuous monitoring by your healthcare team.
Since this is a powerful medicine, it is never for self-use. You will receive detailed instructions and support from the hospital staff regarding your treatment schedule, what to expect during the infusion, and any necessary preparations.
Always follow your ophthalmologist’s exact instructions.

Precautions & side effects
Ocrelizumab is a powerful medicine that suppresses the immune system, and as such, several important precautions must be taken:
- Immune System Suppression: This medicine significantly lowers your body’s ability to fight off infections. This means you will have an increased risk of developing various infections.
- Screening for Tuberculosis and Hepatitis: Before starting Ocrelizumab, it is usually required to undergo screening tests for tuberculosis (TB) and hepatitis (B and C). This is because the medicine can reactivate these dormant infections. If you test positive, your doctor will discuss appropriate management before or during treatment.
- Infusion Reactions: Some patients may experience reactions during or shortly after the infusion. These can include symptoms like itching, rash, fever, chills, headache, or dizziness. You will be closely monitored by healthcare staff during and after your infusion to manage any such reactions promptly.
- Specialist Supervision and Monitoring: Ocrelizumab is only used under strict specialist supervision with regular monitoring. Your doctor will conduct regular check-ups and tests to monitor your health, immune status, and the effectiveness of the treatment.
- Never for Self-Use: This medicine is administered only by specialists in a hospital or clinic setting and is never intended for self-administration at home.
- Vaccinations: Discuss your vaccination history and any planned vaccinations with your doctor before starting Ocrelizumab, as some vaccines may not be safe or effective during treatment.
- Pregnancy and Breastfeeding: If you are pregnant, planning to become pregnant, or breastfeeding, it is vital to inform your doctor immediately. They will discuss the potential risks and benefits and guide you on the safest course of action.
Always communicate any new symptoms, infections, or concerns to your healthcare team promptly. Your safety and well-being are our top priority at Pristine Eye Hospitals.
Understanding Multiple Sclerosis and Optic Neuritis
Multiple Sclerosis (MS) is a chronic condition that affects the central nervous system, which includes the brain, spinal cord, and optic nerves. In MS, the body’s immune system mistakenly attacks the protective covering (myelin sheath) of nerve fibers, leading to communication problems between your brain and the rest of your body. This damage can cause a wide range of symptoms that vary from person to person, including fatigue, numbness or tingling, muscle weakness, problems with balance and coordination, and vision issues. Optic neuritis is a common symptom of MS, where the optic nerve, responsible for transmitting visual information from your eye to your brain, becomes inflamed. This inflammation can lead to sudden vision loss, blurred vision, or pain with eye movement, usually in one eye. While the vision changes from optic neuritis can be frightening, they often improve over time. Understanding your condition is the first step towards managing it effectively, and our specialists at Pristine Eye Hospitals are here to provide comprehensive care and support.
General Advice for Patients Receiving IV Infusions
Receiving an intravenous (IV) infusion like Ocrelizumab involves a visit to the hospital or clinic. Here’s what you can generally expect and how to prepare: Before your appointment, ensure you have discussed any concerns or questions with your doctor. It’s often helpful to wear comfortable clothing, as you will be sitting for some time. You might want to bring a book, music, or a device to keep yourself occupied during the infusion. It’s also a good idea to have a light meal and stay well-hydrated before your infusion, unless advised otherwise by your doctor. During the infusion, a trained nurse or healthcare professional will insert a small needle into a vein, usually in your arm, and connect it to an IV bag containing the medicine. The infusion will be given slowly over a period of time, and you will be monitored closely for any reactions or discomfort. After the infusion, the needle will be removed, and the site will be bandaged. You will typically be observed for a short period to ensure you are feeling well before you can go home. Always follow any specific post-infusion instructions given by your healthcare team.
Maintaining Your Health and When to Seek Help
Since Ocrelizumab can suppress your immune system, it’s especially important to take extra care of your health. Practice good hygiene, such as frequent hand washing, to reduce your risk of infection. Try to avoid close contact with people who are sick. Maintain a healthy lifestyle with a balanced diet, regular exercise (as advised by your doctor), and adequate sleep to support your overall well-being. It is crucial to be vigilant for any signs of infection, such as fever, chills, persistent cough, sore throat, or unusual pain. If you experience any of these symptoms, or any other new or worsening symptoms, contact your doctor or the hospital immediately. Do not wait. Also, if you notice any changes in your vision, new neurological symptoms, or have concerns about your treatment, reach out to your healthcare team at Pristine Eye Hospitals. We are committed to providing you with continuous care and support throughout your treatment journey.
