What Is Ravulizumab Injection?
Ravulizumab is a special type of medicine known as a monoclonal antibody. Think of your immune system as your body's security guard force.
Sometimes, this security force becomes too active and attacks your healthy cells by mistake. This medicine steps in to help calm that overactive immune system down.
Doctors mainly use this medicine to treat a few specific blood and muscle conditions. These conditions can cause serious health challenges if left untreated.
Conditions Treated by Ravulizumab
Your care team uses this medicine for three main medical conditions:
- Atypical Hemolytic Uremic Syndrome (aHUS): This condition causes red blood cells to break down and form abnormal blood clots. These clots can block small blood vessels in your body.
- Paroxysmal Nocturnal Hemoglobinuria (PNH): In this rare condition, your immune system destroys your red blood cells too early. This leads to severe anemia and tiredness.
- Myasthenia Gravis: Here, your immune system blocks the signals between your nerves and muscles. This causes your muscles to tire out and weaken very quickly.
By keeping your immune system balanced, this medicine stops red blood cells from breaking apart. It also prevents unwanted blood clots from clogging your blood vessels.
Things to Tell Your Doctor Before Starting
Before you receive your first dose, your doctor needs a complete picture of your health. Sharing your full medical history keeps you safe during treatment.
Make sure you talk openly with your doctor about the following important details:
- Active infections: Tell your doctor if you have a fever, cough, cold, or any other infection. Because this medicine affects your immune system, a current infection could get worse.
- Allergies: Mention any past allergic reactions to Ravulizumab, other medicines, foods, or dyes.
- Pregnancy: Let your doctor know right away if you are pregnant or trying to get pregnant.
- Breastfeeding: Tell your doctor if you are nursing or plan to breastfeed your baby.

Check Availability →How Is This Medicine Given?
You cannot take this medicine at home by yourself. A doctor or trained nurse gives you Ravulizumab as an infusion into a vein at a hospital or clinic.
Before every treatment session, the clinic staff will give you a special medicine guide. Read and review this guide carefully every single time you go.
Children can also receive this medicine under specific medical supervision. It is safe for children starting from one month of age when prescribed by a specialist.
What Happens If You Get Too Much?
Because medical staff give you this medicine in a controlled clinic setting, getting an overdose is very rare. If you ever suspect you received too much, act quickly.
Call your local emergency number right away, such as 911 in the US or Canada, 999 in the UK, or go straight to the nearest Emergency Department.
What If You Miss a Dose?
This medicine follows a strict schedule to work properly. Missing your scheduled treatment day can reduce how well the medicine protects you.
If you miss your appointment, call your doctor or clinic right away. They will reschedule your dose as soon as possible to keep you safe.
What to Watch For During Treatment
Your care team will monitor your health closely while you receive this medicine. If your symptoms do not improve or start getting worse, tell your doctor right away.
Because this medicine lowers your immune defenses, your body is more vulnerable to infections. Extra caution is necessary every day.
Watch out for signs like a fever, chills, sore throat, or a persistent cough. Do not try to treat these symptoms at home by yourself.
Call your doctor right away if you notice any signs of illness. Try to stay away from crowded places or people who are sick during your treatment.
You will also need to visit your clinic regularly for routine blood tests. These tests help your doctor track your progress and keep you safe.
Can Other Medicines Interfere?
Yes, certain medicines can interact with Ravulizumab. For example, medicines like Efgartigimod and immune globulin can affect your treatment plan.
Give your doctor a complete list of everything you take. Include prescription drugs, over-the-counter medicines, vitamins, and herbal supplements.
You should also be honest about smoking, alcohol use, or any other substances. Sharing this information helps your medical team protect your health.
