What Eculizumab is used for
Eculizumab is a specialised medicine primarily used in the field of Neuro-Ophthalmology. It is prescribed for certain serious conditions that affect both the nervous system and the eyes. At Pristine Eye Hospitals, our specialists may recommend Eculizumab for:
- Neuromyelitis Optica Spectrum Disorder (NMOSD), specifically in patients who test positive for AQP4 antibodies. This is a rare, chronic autoimmune disorder that primarily affects the optic nerves and spinal cord. It can lead to vision loss, weakness, numbness, and other neurological symptoms. Eculizumab helps to reduce the frequency and severity of attacks in these patients.
- Refractory Myasthenia Gravis (MG). Myasthenia Gravis is a chronic autoimmune neuromuscular disease that causes weakness in the skeletal muscles, which are responsible for breathing and moving parts of the body, including the eyes and eyelids. ‘Refractory’ means that the condition has not responded adequately to other standard treatments. Eculizumab can be used in these specific cases to help manage the muscle weakness.
These conditions are complex and require careful diagnosis and management by highly experienced specialists.
How it works
Eculizumab is a type of medicine known as a ‘complement inhibitor’. To understand how it works, it’s helpful to know a little about the body’s immune system.
Our immune system has a complex defence mechanism, part of which is called the ‘complement system’. While the complement system is vital for fighting infections, sometimes it can mistakenly attack healthy parts of the body in autoimmune conditions. In conditions like Neuromyelitis Optica Spectrum Disorder (NMOSD) and Myasthenia Gravis (MG), certain antibodies produced by the immune system can cause damage to nerves and muscles.
Eculizumab works by specifically blocking a key component of this complement system, called ‘complement C5’. By blocking C5, Eculizumab prevents the complement system from initiating a cascade of events that would otherwise lead to antibody-mediated nerve and muscle damage. In simpler terms, it acts like a shield, protecting the delicate nerve and muscle tissues from being attacked and damaged by the body’s own immune system.
This targeted action helps to reduce inflammation and prevent further damage, thereby helping to control the symptoms and progression of these serious conditions.
How it’s used
Eculizumab is a powerful and highly specialised medicine that is administered as an intravenous (IV) infusion. This means the medicine is delivered directly into your bloodstream through a vein, typically in your arm.
It is crucial to understand that Eculizumab is never for self-use. It must always be given by specialists in a hospital or clinic setting, such as Pristine Eye Hospitals, where you can be closely monitored by trained medical professionals.
The dosing schedule for Eculizumab is carefully determined by your specialist based on your specific condition and needs. Typically, after an initial period, it is given as a maintenance dose every two weeks. Your doctor will create a detailed treatment plan for you, outlining the frequency and duration of your infusions.
During each infusion session, healthcare staff will prepare the medicine and administer it slowly over a specific period. You will be monitored throughout the infusion to ensure your safety and to watch for any immediate reactions. After the infusion, you may be asked to remain in the clinic for a short period for further observation.
It is very important to attend all your scheduled appointments for Eculizumab infusions to ensure the medicine works effectively and to maintain its benefits. If you miss an appointment or have any concerns about your treatment schedule, please contact your doctor or the hospital staff immediately.
Always follow your ophthalmologist’s exact instructions.

Please note
Powerful medicine that suppresses the immune system. Screening for tuberculosis and hepatitis is usually required before starting, and it raises the risk of infection. Used only under specialist supervision with regular monitoring. This is given only by specialists in a hospital or clinic setting and is never for self-use.
Precautions & side effects
Eculizumab is a powerful medicine that requires careful consideration and monitoring due to its effects on the immune system. Here are some important precautions and warnings you need to be aware of:
- Meningococcal Vaccination: It is absolutely mandatory to receive a meningococcal vaccination before starting Eculizumab treatment. This is because Eculizumab can significantly increase your risk of developing serious and life-threatening meningococcal infections. Your doctor will ensure you are vaccinated well in advance of starting the treatment.
- Immune System Suppression and Infection Risk: Eculizumab works by suppressing a part of your immune system. While this is beneficial for treating your condition, it also means your body’s ability to fight off infections is reduced. You will have a higher risk of developing various infections.
- Screening for Infections: Before starting Eculizumab, your doctor will usually require screening tests for tuberculosis (TB) and hepatitis. This is to ensure that any pre-existing infections are identified and managed appropriately before you begin treatment, as Eculizumab could worsen them.
- Specialist Supervision and Monitoring: This medicine is only used under strict specialist supervision with regular monitoring. This includes blood tests and clinical evaluations to assess the effectiveness of the treatment and to monitor for any potential side effects or complications.
- High Cost: Eculizumab is a very high-cost medicine. Your healthcare team will discuss the financial implications and any available support options with you.
- Hospital Use Only: As mentioned, Eculizumab is given only by specialists in a hospital or clinic setting and is never for self-use.
- Report Any Symptoms: Because of the increased risk of infection, it is crucial to report any signs of infection to your doctor immediately. This includes fever, chills, headache, stiff neck, rash, confusion, or any unusual symptoms.
Your doctor and the healthcare team at Pristine Eye Hospitals will provide you with detailed information and guidance regarding all necessary precautions and what to look out for during your treatment.
Understanding Your Condition and Treatment
At Pristine Eye Hospitals, we understand that being diagnosed with a condition like Neuromyelitis Optica Spectrum Disorder (NMOSD) or Myasthenia Gravis (MG) can be overwhelming. These are complex autoimmune conditions where your body’s immune system mistakenly attacks its own healthy tissues. In NMOSD, this often affects the optic nerves (leading to vision problems) and the spinal cord. In MG, it causes muscle weakness, which can impact eye movements, eyelid control, and even breathing.
Eculizumab, known by its brand name Soliris, is a cutting-edge treatment that your specialist may recommend. It’s important to remember that this medicine is part of a comprehensive treatment plan tailored just for you. Our goal is to help manage your symptoms, prevent further damage, and improve your quality of life. We encourage you to ask any questions you have about your condition and its treatment. Understanding your health journey is the first step towards better management.
General Hygiene and Storage for Your Health
While Eculizumab is given as an infusion in a hospital setting and doesn’t require home storage, maintaining good general hygiene is even more critical when you are on a medicine that affects your immune system. Here are some general tips to help protect yourself:
- Hand Hygiene: Wash your hands frequently and thoroughly with soap and water, especially before eating, after using the restroom, and after being in public places. Hand sanitiser (alcohol-based) can be used when soap and water are not available.
- Avoid Crowds and Sick Individuals: Try to avoid large crowds, especially during flu season, and stay away from people who are visibly sick.
- Food Safety: Practice good food hygiene. Wash fruits and vegetables thoroughly, cook meats to the recommended temperatures, and avoid raw or undercooked foods that could carry bacteria.
- Personal Care: Keep your living environment clean. Regular bathing and oral hygiene are also important.
- Vaccinations: Besides the mandatory meningococcal vaccine, discuss other recommended vaccinations (like flu shots) with your doctor to further protect your health.
These simple steps can significantly reduce your risk of infections, which is particularly important when your immune system is suppressed.
When to Seek Medical Help
Your health and safety are our top priority at Pristine Eye Hospitals. While Eculizumab is a vital treatment, it’s crucial to be aware of when to seek immediate medical attention. Because this medicine suppresses your immune system, you are at a higher risk of infections. Please contact your doctor or seek emergency medical care immediately if you experience any of the following:
- Signs of Infection: This is paramount. Look out for fever (temperature above 100.4°F or 38°C), chills, severe headache, stiff neck, sensitivity to light, confusion, body aches, unusual tiredness, sore throat, cough, or any new or worsening pain.
- Allergic Reaction: Although rare with infusions, signs can include rash, itching, swelling (especially of the face, tongue, or throat), severe dizziness, or trouble breathing.
- Unusual Bleeding or Bruising: Report any unexpected bleeding, nosebleeds, or easy bruising.
- Any New or Worsening Symptoms: If you notice any new or worsening neurological symptoms related to your condition, or any other concerning changes in your health, do not hesitate to contact your healthcare team.
Always keep the contact number for Pristine Eye Hospitals or your specialist handy. Early detection and treatment of any complications are essential for your well-being.
