Myasthenia Gravis Explained
Loading dose
Myasthenia gravis is a chronic (long-term) autoimmune disorder that occurs when your immune system whacks your own cells. The result? Your voluntary muscles tire easily and weaken, and fatigue settles in. And here's the kicker: symptoms intensify during increased activity and improve with rest. Common symptoms include droopy eyelids, weak muscles in the limbs, neck, and eyes, fatigue, blurry or double vision, trouble chewing, swallowing, speaking, and breathing.

Who Needs Ultomiris?
Ultomiris gets prescribed to adults with a specific type of myasthenia gravis called generalized myasthenia gravis (gMG) who also test positive for anti-acetylcholine receptor (AChR) antibodies. "Generalized" means multiple muscle groups throughout the body are affected, and "anti-AChR positive" means your immune system produces antibodies that block acetylcholine receptors.
40 kg to less than 60 kg (approximately 88 lb to less than 132 lb)
Before they greenlight you for Ultomiris, they may perform a blood test to confirm if your gMG is indeed anti-AChR positive. Ask your doc to clarify if Ultomiris is suitable for your type of myasthenia gravis.

How Ultomiris Treats Myasthenia Gravis
3,000 mg every 8 weeks
If your doc prescribes Ultomiris to tackle your myasthenia gravis, you might wonder how it works its magic. Here's the deal:
The Way Ultomiris Works
60 kg to less than 100 kg (approximately 132 lb to less than 220 lb)
Ultomiris's exact mechanism in treating myasthenia gravis remains somewhat of a mystery, but it's thought to dampen the activity of a complement system protein called C5 in the neuromuscular junction (NMJ). The NMJ is the bridge between nerve cells and the muscles they control. In theory, by lowering C5 activity at the NMJ, Ultomiris helps nerve impulses reach your muscles, reducing fatigue and weakness and possibly boosting muscle strength.

How Well Does Ultomiris Work for Myasthenia Gravis?
3,300 mg every 8 weeks
Ultomiris demonstrated significant improvements in adults with gMG who were anti-AChR positive, allowing them to perform daily living activities more easily in clinical studies. For the nitty-gritty details of these studies, consult the Ultomiris prescribing information. Your healthcare provider or pharmacist can offer additional insights into the effectiveness of Ultomiris based on these studies.
Receiving Your Ultomiris for Myasthenia Gravis
100 kg or more (approximately 220 lb or more)
Let's review the gist of the usual Ultomiris dosages for myasthenia gravis, but remember your doc will recommend the dosage that's best for you. Reach out to your doc if you have questions about your Ultomiris dosage or the method of administration.
3,000 mg
Ultomiris comes in three strengths:
3,600 mg every 8 weeks
- 300 mg/30 mL
- 300 mg/3 mL
- 1,100 mg/11 mL
The Dosage
The recommended dosage regimen for Ultomiris to treat myasthenia gravis is based on your body weight in kilograms (kg). 1 kg is roughly 2.2 pounds (lb).
Ultomiris treatment typically starts with a loading dose. Two weeks after the loading dose, you continue treatment with a maintenance dose, usually every 8 weeks.

The use of Ultomiris to manage myasthenia gravis may produce side effects that could be mild or serious. Remember, side effects may differ when treating other conditions.
Mild Side Effects
Drug class
Some mild side effects reported with Ultomiris include:
complement inhibitor
- Diarrhea
- Upper respiratory infection, such as a common cold
- Abdominal pain
- Urinary tract infections (UTIs)
- Back pain
- Lightheadedness
- Mild infusion reactions, like muscle spasms or discomfort in arms or legs
neonatal Fc receptor blocker
These side effects may resolve in a few days to weeks, but if they persist or bother you, reach out to your healthcare provider or pharmacist.
Serious Side Effects
Though not common, serious side effects may happen with Ultomiris. These include:
- Serious infections, including COVID-19 and pneumonia
- Serious infusion reactions, like elevated or lowered blood pressure, severe shivering, chills, fever, and rapid heartbeat
- Risk of serious meningococcal infections
If you experience serious side effects, contact your doctor right away. In a life-threatening emergency, call 911 or your local emergency number.
Allergic Reaction
Ultomiris might lead to an allergic reaction for some people. Reactions can range from mild to serious.
If you notice mild symptoms, such as a rash, call your doctor right away. They may have solutions to help manage your symptoms and advise you on whether to keep taking the med.
For severe allergic reactions, such as swelling or difficulty breathing, contact 911 or your local emergency number immediately. These symptoms warrant immediate medical attention as they could become life-threatening. If you've had a serious allergic reaction to Ultomiris before, your doc may recommend a different medication.
Before Receiving Ultomiris
Before you receive Ultomiris, there are vital considerations to keep in mind. Ultomiris might not be suitable if you have specific medical conditions or other factors that could impact your health. Here are some critical details to discuss with your doc:
Boxed Warning: Risk of Serious Meningococcal Infections
Ultomiris carries a "boxed warning" for the risk of serious meningococcal infections. This is the gravest warning from the FDA.
Treatment with Ultomiris increases the risk of serious meningococcal infections, such as meningitis, which can be life-threatening. Symptoms of meningococcal infections include:
- Sudden fever, headache, or stiff neck
- Nausea and vomiting
- Sensitivity to light
- Confusion
- Drowsiness
What to Do
Before you begin Ultomiris treatment, your doc will ensure you're up to date on meningococcal vaccines. If you haven't had them, they will give you the required jabs at least 2 weeks before Ultomiris therapy starts. If your situation necessitates immediate Ultomiris treatment, they may prescribe antibiotics to help prevent infections – for the first 2 weeks post your first Ultomiris infusion.
The risk of serious meningococcal infections applies throughout Ultomiris treatment and for at least 8 months after your last dose. Symptoms of a meningococcal infection during this period? Reach out to your doctor, but call 911 or go to the closest emergency room if your symptoms feel life-threatening.
Due to this risk, Ultomiris is only accessible through a risk evaluation and mitigation strategy (REMS) program. As part of this program, you will need to carry the Ultomiris Patient Safety Card throughout treatment and for at least 8 months after your last dose. For more information about the Ultomiris REMS program, visit the program website or call 1-888-765-4747.
Other Warnings
In addition to boxed warnings, Ultomiris has other warnings. If any of the following medical conditions or other health factors apply to you, discuss them with your doc before receiving Ultomiris:
- Active infection
- Pregnancy
- Breastfeeding
- Regular alcohol drinking
- Known allergy to Ultomiris or its ingredients
