Meningococcal infections, which may rapidly become life-threatening or fatal if not recognized and treated early, have been reported in patients treated with eculizumab. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for meningococcal vaccination in patients with complement deficiencies. Immunize patients with a meningococcal vaccine at least 2 weeks prior to administering the first dose of eculizumab, unless the risks of delaying eculizumab therapy outweigh the risk of developing a meningococcal infection. Monitor patients for early signs of meningococcal infections and evaluate immediately if infection is suspected. Eculizumab is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS). Under the eculizumab REMS prescribers must enroll in the program. Enrollment in the eculizumab REMS program and additional information are available by telephone: 1-888-SOLIRIS (1-888-765-4747) or at solirisrems.com .

Uses For eculizumab
Eculizumab injection is used to treat a type of blood disease called paroxysmal nocturnal hemoglobinuria (PNH). Eculizumab helps reduce red blood cell destruction or breakdown (hemolysis) in patients with PNH.
Eculizumab is also used to treat a serious kidney disorder called atypical hemolytic uremic syndrome (aHUS).
Eculizumab injection is also used to treat a nerve and muscle disease called generalized myasthenia gravis (gMG) in patients who are anti-acetylcholine receptor (AchR) antibody positive.
Eculizumab injection is a monoclonal antibody that works on the immune system.
Eculizumab is available only under a restricted distribution program called Soliris® REMS (Risk Evaluation and Mitigation Strategy) Program.
Before Using eculizumab
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For eculizumab, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to eculizumab or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of eculizumab injection to treat atypical hemolytic uremic syndrome in children. However, safety and efficacy of eculizumab injection to treat paroxysmal nocturnal hemoglobinuria and generalized myasthenia gravis have not been established in children.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of eculizumab injection in the elderly.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
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. In these cases, your doctor may want to change the dose, or other precautions may be necessary. 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.
Other Medical Problems
The presence of other medical problems may affect the use of eculizumab. Make sure you tell your doctor if you have any other medical problems, especially:
- Infection—Use with caution. Eculizumab may decrease your body’s ability to fight infection.
- Meningococcal infection—Should not be given to patients with this condition.
- No current vaccination against meningitis infection—Should not be given to patients with this condition unless the doctor decides that urgent treatment is needed.
- Neutropenia (low white blood cells) or
- Weak immune system—Use with caution. May cause side effects to become worse and increase risks for infection.
Proper Use of eculizumab
A nurse or other trained health professional will give you eculizumab. Eculizumab is given through a needle placed into one of your veins. It must be injected slowly, so your IV tube will need to stay in place for at least 35 minutes.
It is very important that you understand the requirements of the Soliris® REMS program, and become familiar with the Soliris® medication guide. Read and follow these instructions carefully. Ask your doctor if you have any questions. Ask your pharmacist for the medication guide if you do not have one.
Precautions While Using eculizumab
It is very important that your doctor check your progress at regular visits to make sure that eculizumab is working properly. Blood and urine tests may be needed to check for unwanted effects.
Eculizumab may increase your chance of having serious infections, including a meningococcal infection. Avoid people who are sick or have infections. Tell your doctor right away if you develop headaches, nausea, vomiting, fever, a stiff neck or back, a rash, confusion, muscle aches, or if your eyes have become sensitive to light. Make sure you have received a vaccine to prevent meningococcus infections at least two weeks before you receive eculizumab. If you have already received the meningococcal vaccine in the past, your doctor will decide if you need another dose.
Ask your doctor for a patient safety card. This card will list the symptoms of meningococcus infections and what to do if you have them. Carry the card with you at all times during treatment and for 3 months after your last dose. You will need to show the card to any doctor who treats you.
For patients with PNH: When eculizumab is stopped you could have red blood cell destruction or breakdown (hemolysis). Your doctor will need to monitor you closely for at least 8 weeks after you stop using eculizumab. Be sure to keep all appointments.
For patients with aHUS: Your doctor may also need to check for blood clots in your small blood vessels, called thrombotic microangiopathy (TMA) for at least 12 weeks after stopping treatment with eculizumab. The signs and symptoms of TMA include chest pain, difficulty with breathing, mental depression or anxiety, or seizures. Call your doctor right away if you notice any of these signs and symptoms.
Eculizumab may cause infusion-related reactions. These can be life-threatening and require immediate medical attention. Tell your doctor right away if you start to have a fever, chills or shaking, dizziness, trouble breathing, itching or rash, lightheadedness or fainting after receiving eculizumab.
