Understand the common and serious side effects of Briumvi (ublituximab) for multiple sclerosis. Learn about infusion reactions, infection risks, PML, and when to contact your doctor for safe MS treatment.
Living with multiple sclerosis (MS) often involves managing complex treatments designed to slow disease progression and alleviate symptoms. Briumvi (ublituximab) is one such medication, an intravenous infusion approved for the treatment of relapsing forms of multiple sclerosis (RMS) in adults. While Briumvi offers a valuable therapeutic option, like all medications, it comes with potential side effects. Understanding these effects, both common and serious, is crucial for patients and caregivers to ensure safe and effective treatment.
This comprehensive guide aims to provide detailed information about Briumvi's side effects, how to recognize them, what to do if they occur, and when to seek medical attention. Our goal is to empower you with the knowledge needed to have informed discussions with your healthcare provider and manage your MS treatment effectively.
Briumvi is a monoclonal antibody that targets CD20, a protein found on the surface of B cells. By depleting these B cells, Briumvi helps to reduce inflammation and damage to the myelin sheath in the central nervous system, which are hallmarks of MS. It is administered via intravenous infusion, typically with a shorter infusion time compared to some other CD20-targeting therapies.
Many people receiving Briumvi experience side effects, most of which are mild to moderate and manageable. The most frequently reported side effects are infusion-related reactions and infections.
Infusion-related reactions are the most common side effects associated with Briumvi, often occurring during or within 24 hours of an infusion. These reactions are usually mild to moderate but can sometimes be severe.
Briumvi works by depleting B cells, which are an important part of the immune system. This can increase your risk of developing infections.
Beyond IRRs and infections, other frequently reported side effects include:
These side effects are generally mild and often resolve on their own. If they persist or become bothersome, discuss them with your doctor.
While less common, Briumvi can cause serious side effects that require immediate medical attention. It is vital to be aware of these potential risks.
PML is a rare but very serious brain infection caused by the John Cunningham (JC) virus. It can lead to severe disability or death. Briumvi, like other CD20-targeting therapies, carries a risk of PML.
For individuals who have previously been infected with Hepatitis B virus, Briumvi can cause the virus to reactivate, leading to serious liver problems, including liver failure and death. This risk is particularly high in patients who are carriers of HBV.
Beyond common infections, Briumvi can increase the risk of more severe infections, including those caused by bacteria, fungi, or other viruses, such as herpes zoster (shingles).
Briumvi can lead to a reduction in immunoglobulin levels (antibodies) in the blood, a condition called hypogammaglobulinemia. This can further compromise the immune system and increase the risk of recurrent or severe infections.
There is a theoretical risk of an increased incidence of malignancies (cancers), including skin cancer and breast cancer, with immunosuppressive therapies like Briumvi. This risk is being continually evaluated in ongoing studies.
While many side effects are mild, it's crucial to know when to seek medical advice. Contact your doctor immediately or seek emergency care if you experience any of the following:
Proactive management and open communication with your healthcare team are key to safely navigating Briumvi treatment.
Briumvi may not be suitable for everyone. You should not take Briumvi if you have:
Additionally, discuss your full medical history with your doctor, including any history of:
It is not known whether Briumvi can harm an unborn baby. Women who are pregnant or planning to become pregnant should discuss the risks and benefits with their doctor. It is recommended to use effective contraception during Briumvi treatment and for at least 6 months after the last dose.
It is also unknown if Briumvi passes into breast milk. Nursing mothers should discuss the best feeding option with their doctor while on Briumvi.
Briumvi's effect on the immune system means it can potentially interact with other medications, particularly those that also suppress the immune system. Always provide your doctor with a complete list of all medications, supplements, and herbal products you are currently taking to avoid potential interactions.
Infusion-related reactions typically occur during or within 24 hours of the infusion and usually resolve within a few hours to a day. Other common side effects like headache or fatigue may last for a few days. The increased risk of infection can persist for several months after your last Briumvi dose as your B cell levels recover.
Long-term risks include a sustained reduction in immunoglobulin levels, which can lead to an increased susceptibility to infections. There is also an ongoing assessment of the long-term risk of malignancies, though more data is needed. Your doctor will monitor you for these potential long-term effects.
Hair loss is not listed as a common or serious side effect in the official prescribing information for Briumvi. If you experience hair loss while on Briumvi, discuss it with your doctor to rule out other potential causes.
Yes, Briumvi is considered an immunosuppressant because it works by depleting B cells, which are a type of white blood cell crucial for the immune system's function. This action helps treat MS but also increases the risk of infections.
If you miss a Briumvi dose, contact your healthcare provider immediately. They will advise you on the next steps and reschedule your infusion to maintain the effectiveness of your treatment.
Briumvi offers an important treatment option for individuals with relapsing forms of multiple sclerosis. While effective, it's essential for patients to be well-informed about its potential side effects. By understanding what to expect, recognizing symptoms, and maintaining open communication with your healthcare team, you can manage your treatment safely and effectively. Always remember that your doctor is your best resource for personalized medical advice and guidance regarding Briumvi and your MS treatment plan.
