Myasthenia Gravis Treatment with Ultomiris: Exploring Its Mechanism and Additional Information
Hey there! Today, we're diving into Ultomiris, a life-changing infusion solution that's making a difference for people living with myasthenia gravis. As you read this, remember to consult your healthcare provider for personalized guidance.
Ultomiris is an IV infusion medication that requires a professional touch. This biologic, belonging to the complement inhibitors drug class, isn’t available as a biosimilar.
Here's the lowdown on Ultomiris, complete with some fascinating insights. Keep in mind, it's essential to consult your healthcare provider for accurate and personalized details.
Understanding Myasthenia Gravis
Body weight
Myasthenia gravis is an autoimmune condition that interferes with proper muscle and nerve communication. You probably know it as the culprit behind those tired, weak muscles that just won't cooperate.
Loading dose
Symptoms vary, but they often worsen during activity and improve with rest. They include:
Maintenance dose
- Drooping eyelids
- Weak muscles in limbs, neck, and eyes
- Fatigue
- Blurry or double vision
- Difficulty chewing, swallowing, speaking, and breathing
Who Gets Ultomiris?
40 kg to less than 60 kg (approximately 88 lb to less than 132 lb)
Ultomiris is prescribed exclusively for adult generalized myasthenia gravis (gMG) patients who test positive for anti-acetylcholine receptor (AChR) antibodies. "Generalized" refers to muscle groups throughout the body being affected, distinguishing it from ocular myasthenia gravis, which impacts only eye muscles.
2,400 mg
Before prescribing Ultomiris, your doctor will likely check your blood for AChR antibodies to determine if Ultomiris is the best treatment for your unique situation.
3,000 mg every 8 weeks
How Ultomiris Transforms Myasthenia Gravis
Wondering how Ultomiris works its magic? It's not entirely clear, but it's thought to block the activity of a complement system protein called C5 at the neuromuscular junction (NMJ). The NMJ is the area where nerve cells communicate with the muscles they control. By reducing C5 activity at the NMJ, Ultomiris ensures that nerve signals reach muscles effectively. This, in turn, may help alleviate fatigue and muscle weakness, boosting your strength.

The Power of Ultomiris: Clinical Evidence
2,700 mg
In clinical trials, Ultomiris proved effective at enhancing the ability to carry out daily tasks for gMG patients who were AChR antibody positive. For more details, check out the prescribing information or ask your doctor or pharmacist.
3,300 mg every 8 weeks
Riding the Ultomiris Wave: Dosages and Frequency
Ultomiris comes in several strengths: 300 mg/30 mL, 300 mg/3 mL, and 1,100 mg/11 mL. The dosage your doctor recommends will depend on your body weight.
100 kg or more (approximately 220 lb or more)
Treatment usually begins with a loading dose, followed by a maintenance dose (typically every 8 weeks) after 2 weeks. Check out the dosage chart below for more specifics. Keep in mind that treatment strategies may differ for other conditions.
3,000 mg
3,600 mg every 8 weeks
Your doctor will guide you through the specifics of your Ultomiris dosing and administration schedule.
The Ups and Downs: Ultomiris Side Effects
Ultomiris may cause side effects whose severity ranges from mild to serious. Remember, everyone's different, so while some may experience mild side effects, others might avoid them entirely. Frequently reported mild side effects include:
- Diarrhea
- Upper respiratory infections
- Abdominal pain
- Urinary tract infections
- Back pain
- Dizziness
Ultomiris
However, there's a chance you could experience more severe side effects, such as:
Vyvgart
- Serious infections, including COVID-19 and pneumonia
- Serious infusion reactions, including increased or decreased blood pressure, severe shivering, and a high fever
Serious side effects are rare, but it's crucial to contact your doctor right away if they occur.

Safety First: Precautions and Considerations
solution for IV infusion
Before beginning Ultomiris treatment, there are some factors to keep in mind. These precautions have been added to ensure the safety and efficacy of your treatment journey.
solution for IV infusion
Caution #1: Boxed Warning – Meningococcal Infections
Ultomiris carries a boxed warning for the increased risk of serious meningococcal infections. Symptoms include a sudden fever, headache, or stiff neck, nausea and vomiting, sensitivity to light, confusion, and drowsiness.
Dosage frequency
To minimize this risk, your doctor will make sure you’re up-to-date with meningococcal vaccinations before starting treatment. If the need for immediate treatment arises, your doctor may prescribe antibiotics to prevent infection during the first two weeks following your first Ultomiris infusion.
once every 8 weeks
Additional Considerations
once weekly for 4 weeks; your doctor may prescribe additional cycles based on how well Vyvgart works for your symptoms
- Active infections: Discuss with your doctor if you have an active infection before starting treatment.
- Pregnancy: Consult your doctor if there's any chance you might be pregnant before starting Ultomiris treatment.
- Breastfeeding: Consult your doctor before starting treatment if you’re breastfeeding.
- Alcohol consumption: Discuss any alcohol consumption with your doctor.
- Allergic reactions: Inform your doctor if you have had an allergic reaction to Ultomiris or any of its ingredients.
Frequently Asked Questions
Drug class
Q: How does Ultomiris compare to Vyvgart?
complement inhibitor
A: Both Ultomiris and Vyvgart are used to treat gMG, but they differ in dosage frequency and drug class. Ultomiris is given once every 8 weeks, while Vyvgart is administered once weekly for 4 weeks. The dosage frequency might be adjusted based on response. For more information, consult your doctor or pharmacist.

Q: Can I get Ultomiris infusions at home?
A: Possibly! Your doctor may be able to prescribe Ultomiris for home infusion. Ask your doctor if home infusion services are available for you.

[Enrichment Data]Ultomiris (ravulizumab-cwvz) is a monoclonal antibody (mAb) that selectively inhibits complement C5. It is used to treat generalized myasthenia gravis (gMG) in adults who are positive for anti-acetylcholine receptor (AChR) antibodies[4]. The most common adverse reactions (occurring in ≥10% of participants) in clinical trials for gMG treatment included upper respiratory tract infection, diarrhea, abdominal pain, and urinary tract infection, while serious adverse reactions (including ≥1 fatal case) were mainly due to infections[1][3]. Ultomiris is associated with an increased risk of meningococcal infections, particularly within the first 2 months of starting treatment[5]. Consult a healthcare provider for more information.
