Myasthenia Gravis Explained
Loading dose
Myasthenia gravis is a condition where faulty communication between muscles and nerves causes your voluntary muscles to tire quickly and weaken. It’s a chronic autoimmune condition where your immune system mistakenly attacks your own cells.

Symptoms of Myasthenia Gravis
Symptoms for myasthenia gravis vary among individuals but are typically worse during periods of increased activity and improve with rest. These symptoms include:
40 kg to less than 60 kg (approximately 88 lb to less than 132 lb)
- droopy eyelids
- weak muscles in your limbs, neck, and eyes
- fatigue
- blurry or double vision
- difficulty chewing, swallowing, speaking, and breathing

Who Ultomiris is for
3,000 mg every 8 weeks
Ultomiris is prescribed to treat generalized myasthenia gravis (gMG) in adults who are anti-acetylcholine receptor (AChR) antibody-positive.
- "Generalized" means that muscle groups throughout the body are affected, differentiating it from ocular myasthenia gravis, which only affects eye muscles.
- "Anti-acetylcholine receptor (AChR) antibody-positive" means your immune system produces antibodies that block acetylcholine receptors. Acetylcholine is a neurotransmitter that provides signals causing muscle contractions.
60 kg to less than 100 kg (approximately 132 lb to less than 220 lb)
Before prescribing Ultomiris, your doctor may order a blood test to verify if your gMG is AChR antibody-positive. Your doctor can provide more insights on whether Ultomiris is suitable for treating your type of myasthenia gravis.

How Ultomiris Works
3,300 mg every 8 weeks
If your doctor prescribes Ultomiris for myasthenia gravis treatment, you might be wondering how it works to treat your condition.
The Way Ultomiris Works
100 kg or more (approximately 220 lb or more)
The precise working of Ultomiris isn't fully understood, but it's believed to involve the medication's ability to block the activity of a complement system protein called C5 at the neuromuscular junction (NMJ).
3,000 mg
The NMJ is where nerve cells transmit messages to the muscles they control. By reducing C5 activity at the NMJ, Ultomiris enables signals from nerve cells to reach your muscles. This may reduce fatigue and muscle weakness, potentially improving muscle strength.
3,600 mg every 8 weeks
Ultomiris' Effectiveness for Myasthenia Gravis
In clinical trials, Ultomiris effectively enhanced the ability to perform daily living tasks in adults with generalized myasthenia gravis (gMG) who were AChR antibody-positive.
Check out the prescribing information for Ultomiris for more details about these studies. Your doctor or pharmacist can also shed light on how well Ultomiris worked in these studies.
