Myasthenia gravis: What's That all About?
Loading dose
With myasthenia gravis, messed-up communication between muscles and nerves causes voluntary muscles to tire rapidly and become weak[1]. It's a chronic (long-haul) autoimmune disorder, meaning that your immune system doesn't recognize your own cells and attacks them[1].
Maintenance dose
Symptoms:
Symptoms of myasthenia gravis are a tad different for everyone. They tend to worsen after an elevated activity spree and improve with a bit of R&R[1]. Common symptoms include:
40 kg to less than 60 kg (approximately 88 lb to less than 132 lb)
- droopy peepers
- weak limbs, neck, and eye muscles
- exhaustion and sluggishness
- squishy or duplicated vision
- troubles with chewing, gobbling, yakking, and breathing[1]

Who's Ultomiris for?
3,000 mg every 8 weeks
Ultomiris is prescribed solely for adults with generalized myasthenia gravis (gMG) who test positive for anti-acetylcholine receptor (AChR) antibodies[1].
- "Generalized" refers to muscle groups across the body experiencing the brunt of the action. gMG differs from ocular myasthenia gravis, which mainly affects eye muscles[1].
- "Anti-acetylcholine receptor (AChR) antibody-positive" indicates that your immune system churns out antibodies that block acetylcholine receptors. Acetylcholine is a neurotransmitter that transmits signals to cause muscles to contract[1].
60 kg to less than 100 kg (approximately 132 lb to less than 220 lb)
Before giving you Ultomiris, your doctor might order an Anti-AChR blood test to ensure you're suitable for Ultomiris therapy. Your doctor will elaborate on what Ultomiris means for your unique case of myasthenia gravis[1].

How Ultomiris Triumphs over Myasthenia Gravis
3,300 mg every 8 weeks
If your doc signed you up for Ultomiris, you might be curious about how it swoops in to rescue the day[1].
It's all about the science:
100 kg or more (approximately 220 lb or more)
The exact science behind Ultomiris' triumph over myasthenia gravis remains a bit hazy[1]. However, researchers believe that Ultomiris suppresses the activity of a complement system protein called C5 at the neuromuscular junction (NMJ). The NMJ is where nerve cells communicate with the muscles they control[1]. By lowering C5 activity at the NMJ, Ultomiris amplifies messages from nerve cells reaching your muscles. This decrease in fatigue and muscle weakness helps boost muscle strength[1].

The Results Speak for Themselves:
3,600 mg every 8 weeks
In clinical trials, Ultomiris proved to be a bomb when it comes to elevating individuals' abilities to undertake daily tasks[1]. You can ingest more details about these studies by checking out the "Ultomiris prescribing information"[1]. Your doctor or pharmacist can also provide the 411 on how well Ultomiris performed in these trials.
Getting your Dose of Ultomiris
Here's some vital Ultomiris dosage info to help you navigate your treatment[1]. Your doctor will provide personalized dosing guidance, so don't hesitate to chat with them about your questions.
Ultomiris is accessible in three different concentrations:
Ultomiris
- 300 milligrams (mg)/30 milliliters (mL)
- 300 mg/3 mL
- 1,100 mg/11 mL[1]
Vyvgart
Dosage:
Ultomiris treatment commences with a loading dose followed by a maintenance dose[1]. Two weeks post-loading dose, you can anticipate receiving maintenance doses at regular intervals.

Note: In addition to myasthenia gravis, Ultomiris is employed to treat other conditions. Be mindful that the drug dosage may change when used to treat other ailments. Chat with your doctor to learn more!
How Ultomiris is dispersed:
Dosage frequency
Ultomiris arrives at you as an infusion solution for IV administration. Medical practitioners will administer your Ultomiris drips at an infusion center.
once every 8 weeks
The Scheduling of Ultomiris:
once weekly for 4 weeks; your doctor may prescribe additional cycles based on how well Vyvgart works for your symptoms
Generally, you'll receive your Ultomiris maintenance doses every 8 weeks[1]. Your maintenance doses usually start after the 2-week loading dose period.

Drug class
Ultomiris Side Effects
complement inhibitor
Using Ultomiris for myasthenia gravis could lead to side effects ranging from minor to severe. You should be aware that Ultomiris is also used to address conditions like paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), and neuromyelitis optica (NMOSD) spectrum disorder[1]. Side effects may differ depending on the condition Ultomiris is used to treat.

Here's a snapshot of some of the principal side effects reported with Ultomiris[1]:
Mild:
- looseness of the bowels
- common cold
- tummy troubles
- urinary tract infections (UTIs)
- back pain
- dizziness
- mild infusion reactions, which may involve:
- muscle cramps
- discomfort in your limbs
These side effects usually fade within a couple of days to weeks. However, if they linger, intensify, or become bothersome, talk to your doc or pharmacist[1].
Serious:
Although not common, serious side effects have been reported with Ultomiris. These include:
- infections of all shapes and sizes, such as COVID-19 and pneumonia
- harsh infusion reactions, which could involve:
- extreme fluctuation in blood pressure
- chilling sensations, shivering, and fever
- the possibility of severe meningococcal infections (see "Before receiving Ultomiris")[1]
If you encounter serious side effects, call your doctor right away. In instances where the side effects seem life-threatening or you believe a medical emergency is at hand, reach out to 911 or your local emergency number immediately[1].
"For any side effects experienced while receiving Ultomiris, be sure to report them to the Food and Drug Administration (FDA) at [MedWatch][4] or by calling 800-FDA-1088."
The intravenous infusion of Ultomiris is a biologic agent that belongs to the complement inhibitors drug class. It isn't available as a biosimilar.
Ultomiris carries a boxed warning, the Food and Drug Administration's most severe warning. It's crucial to check the "Before receiving Ultomiris" section for specific details.
People with myasthenia gravis, a chronic autoimmune disorder that weakens voluntary muscles, are primary candidates for Ultomiris. A loading dose initiates treatment followed by maintenance doses after two weeks.
Ultomiris functions by suppressing the activity of a complement system protein called C5 at the neuromuscular junction, which helps improve muscle strength.
Ultomiris has proven effective in increasing individuals' ability to perform daily tasks in clinical trials, benefiting those with myasthenia gravis. Keep in mind that Ultomiris is also used to treat other medical conditions such as paroxysmal nocturnal hemoglobinuria, atypical hemolytic uremic syndrome, and neuromyelitis optica spectrum disorder, which may affect the drug's dosage.
