Myasthenia Gravis: An Explanation
2,400 mg
Myasthenia gravis affects your voluntary muscles, causing weak and tired muscles. This is a long-term autoimmune disorder, meaning your immune system attacks your own cells by mistake.
3,000 mg every 8 weeks
Watch out for the following symptoms:
- Droopy eyelids
- Weak muscles, affecting your limbs, neck, and eyes
- Fatigue
- Blurry or double vision
- Difficulty chewing, swallowing, speaking, and breathing
60 kg to less than 100 kg (approximately 132 lb to less than 220 lb)
Who Benefits from Ultomiris?
2,700 mg
Ultomiris is prescribed to treat adult patients with generalized myasthenia gravis (gMG) who test positive for anti-acetylcholine receptor (AChR) antibodies.
3,300 mg every 8 weeks
Generalized means that multiple muscle groups are affected, distinguishing it from ocular myasthenia gravis, which only affects the eye muscles.
Anti-acetylcholine receptor (AChR) antibody-positive refers to people whose immune systems produce antibodies that block acetylcholine receptors. Acetylcholine is a neurotransmitter that sends signals that cause muscles to contract.
100 kg or more (approximately 220 lb or more)
Your doctor might run a blood test to check if your gMG is AChR antibody-positive. They can help determine if Ultomiris is suitable for your specific case of myasthenia gravis.

How Ultomiris Works Wonders
3,600 mg every 8 weeks
If your doctor prescribes Ultomiris for myasthenia gravis treatment, you may wonder how it works.
The Science Behind Ultomiris
The precise workings of Ultomiris are still not fully understood. However, it's believed to involve its ability to suppress the activity of complement system protein C5 at the neuromuscular junction (NMJ).
The NMJ is the spot where nerve cells communicate with the muscles they control. By decreasing C5 activity at the NMJ, Ultomiris allows nerve cell signals to reach your muscles more effectively, potentially reducing fatigue and muscle weakness and boosting muscle strength.

Is Ultomiris Effective for Myasthenia Gravis?
Vyvgart
Clinical studies indicate that Ultomiris is effective in improving the ability to perform daily tasks in adult patients with gMG who are AChR antibody-positive. You can learn more about these studies by exploring the Ultomiris prescribing information. Your doctor or pharmacist can also provide details about the study results.
Getting Your Ultomiris Fix
Form
Since Ultomiris comes as an IV infusion solution, a healthcare professional will administer it at an infusion center. The recommended dosages for myasthenia gravis treatment are tailored to your body weight, as follows:
solution for IV infusion
- Loading dose: 2,400–3,600 mg (depending on body weight)
- Maintenance dose (every 8 weeks): 3,000, 3,300, or 3,600 mg (depending on body weight)
solution for IV infusion
Your doctor will suggest the best dosage for you, and you can discuss any questions or concerns you might have regarding your Ultomiris dosage or method of administration.
Potential Side Effects of Ultomiris
Dosage frequency
Using Ultomiris for myasthenia gravis might cause mild or serious side effects. Remember that the potential side effects from Ultomiris could differ when treating other conditions. Discuss any questions you have with your doctor or pharmacist.

Serious Side Effects
neonatal Fc receptor blocker
Although not common, serious side effects have been reported with Ultomiris. These can include:
- Severe infections (COVID-19, pneumonia)
- Severe infusion reactions
- Risk of severe meningococcal infections (more on this below)
Contact your doctor immediately if you notice serious side effects while using Ultomiris. If the side effects seem life-threatening or you believe you're experiencing a medical emergency, call 911 or your local emergency number immediately.
Allergy Awareness
For some individuals, Ultomiris can induce an allergic reaction. If you suspect an allergic reaction, follow these guidelines:
- For mild responses (mild rash), contact your doctor right away. They may recommend treatments to help manage your symptoms. They'll also advise whether you should keep taking the medication.
- For severe reactions (swelling or difficulty breathing), call 911 or your local emergency number right away. In serious cases, these symptoms can become life-threatening, needing immediate medical attention. If you've had a severe allergic reaction to Ultomiris, your doctor may suggest an alternative medication.
Pre-Ultomiris Checklist
Before you receive Ultomiris, it's essential to be aware of the following information:
Boxed Warning: Meningococcal Infections
Ultomiris has a boxed warning for the risk of severe meningococcal infections. Before treatment begins, your doctor will ensure that you're up-to-date with meningococcal vaccines. If not, they may administer the needed vaccines at least 2 weeks prior to your Ultomiris treatment. If urgent treatment is required, they may initiate treatment sooner than 2 weeks after meningococcal vaccination. If this applies to you, they'll likely prescribe antibiotics for the first 2 weeks following your first Ultomiris infusion.
The risk of severe meningococcal infections continues throughout your treatment with Ultomiris and persists for at least 8 months after your last dose. Immediately consult your doctor if you think you have symptoms of a meningococcal infection during this period. However, if symptoms seem life-threatening, call 911 or go to the closest emergency room.
Because of this risk, Ultomiris is only available under a risk evaluation and mitigation strategy (REMS) program. Remember to carry the Ultomiris Patient Safety Card throughout treatment and for at least 8 months after your last dose. Learn more about the Ultomiris REMS program at the program website or by calling 1-888-765-4747.
Bonus Info
Wondering how Ultomiris compares to Vyvgart? Both are used to treat generalized myasthenia gravis, but they have differences in form, dosage frequency, and drug class. Your doctor or pharmacist can provide more information about this comparison.
For home infusion services, discuss the possibilities with your doctor to see if this solution is right for you.
Ultomiris Cost and Coverage
Ultomiris costs vary depending on your treatment regimen, insurance plan, and location. Since Ultomiris is a brand-name biologic drug and not available in a biosimilar form, its cost might be higher compared to some other treatments. A program called the Alexion OneSource CoPay Program is available for Ultomiris. Visit this website or call 888-765-4747 for more information and to learn if you're eligible for support.
