Uses of Ocrevus Injection
Benefits of Ocrevus Injection
Multiple sclerosis (MS)
Multiple sclerosis (MS) is a chronic condition where the immune system attacks the protective covering of nerve fibers, causing symptoms such as fatigue, muscle weakness, and difficulty with coordination. In patients with multiple sclerosis (MS), Ocrevus 300mg Injection helps slow the disease's progression. It protects the nerve fibers from further damage, reduces the frequency of relapses, and slows the progression of the disease. When taken regularly in the right dose and duration, Ocrevus 300mg Injection improves the overall quality of life for people living with MS.

How Ocrevus Injection works
Ocrevus 300mg Injection works by targeting a specific protein called CD20, found on the surface of certain B lymphocytes, which are immune cells involved in the damage caused by multiple sclerosis (MS). By binding to CD20, Ocrevus 300mg Injection eliminates these harmful B cells, reducing the immune attack on the nervous system. This helps control the disease, protect the neurological system, and slow the progression of MS, improving overall outcomes for patients.
Quick tips

- Patients need to finish all necessary vaccinations at least six weeks before starting Ocrevus 300mg Injection.
- It is not advised to provide live or live-attenuated vaccines when treating Ocrevus 300mg Injection or until B-cell recovery.
- Be vigilant about signs of infection, such as fever, chills, or persistent cough, and report them to your doctor immediately. Delay treatment if you have an active infection.
