Myasthenia Gravis Treatment in 2026: Your Options Explained

By Anna Curran, RN, BSN, PHN · Last reviewed October 2026

Myasthenia gravis treatment usually combines a few approaches. Pyridostigmine helps muscles get the nerve signal, while steroids and other immune medicines calm the immune attack. Surgery to remove the thymus, short-term IV treatments and newer targeted medicines may also be part of the plan.

There is no cure for MG yet. But treatment has come a long way, and most people can get their symptoms well under control. Here is a plain-language look at each option as of late 2026.

How Doctors Choose Your Myasthenia Gravis Treatment

No single plan fits everyone. According to Mayo Clinic, your treatment depends on:

Your age and overall health
How severe your symptoms are
How fast your MG is changing
Which muscles are affected

Your antibody type also matters. Some newer medicines are approved only for certain types, such as AChR-positive or MuSK-positive MG. Your neurologist will weigh the benefits and side effects of each option with you.

Pyridostigmine (Mestinon)

Pyridostigmine is often the first medicine people try. It slows the breakdown of acetylcholine, the chemical messenger that tells muscles to move. More acetylcholine at the nerve-muscle connection can mean stronger muscles.

It treats symptoms, not the immune problem behind them. Many people take it a few times a day.

Common side effects listed by Mayo Clinic include:

Upset stomach or nausea
Diarrhea
Extra saliva
Sweating

Tell your doctor if side effects bother you. Do not change your dose or schedule on your own.

Steroids and Other Immune Medicines

Corticosteroids

Prednisone is a steroid that calms the immune system so it makes fewer harmful antibodies. It often works well for MG.

The MGFA notes that steroids can make MG weakness temporarily worse in the first two weeks of starting. Your doctor will watch you closely during this time.

Long-term steroid use can cause side effects. Mayo Clinic lists bone thinning, weight gain, diabetes and a higher risk of infection. Your doctor may try to lower your dose over time.

Steroid-sparing immunosuppressants

These medicines also calm the immune system. They are often used along with steroids, or to help lower the steroid dose. They can take months to start working. Examples include:

Azathioprine
Mycophenolate mofetil
Tacrolimus
Cyclosporine
Methotrexate

You will need regular blood tests on these medicines. They can raise your risk of infection and may affect the liver or kidneys.

Thymectomy: Surgery to Remove the Thymus

The thymus is a gland in the upper chest that seems to play a role in MG. Removing it is called a thymectomy.

If you have a thymoma (a growth on the thymus), you will likely need surgery. But thymectomy can also help some people who do not have a tumor. A NINDS-funded study of 126 people found that thymectomy reduced weakness and the need for immune-suppressing medicines.

The benefits are not quick. Mayo Clinic notes that it may take years to see the full effect.

Surgeons may use:

Open surgery through the breastbone
Video-assisted surgery through small cuts
Robot-assisted surgery through small cuts

Smaller cuts may mean less pain and a shorter hospital stay. Your surgeon will help decide which approach is right for you.

Fast-Acting Treatments: IVIG and Plasma Exchange

These treatments work quickly but do not last long. Doctors often use them for a bad flare, a myasthenic crisis or before surgery.

Plasma exchange (plasmapheresis)

A machine filters your blood to remove the harmful antibodies. Mayo Clinic notes the benefit usually lasts only a few weeks. Possible risks include low blood pressure, bleeding and heart rhythm problems.

IVIG (intravenous immunoglobulin)

IVIG gives you antibodies from healthy donors through an IV. These change how your immune system acts. Mayo Clinic says the benefit often starts within about a week and lasts about 3 to 6 weeks. Side effects are usually mild, such as headache, chills or dizziness.

Newer Targeted Medicines

In the past several years, the FDA has approved a group of medicines that target specific parts of the immune attack. Most are given by IV or injection on a regular schedule. Here is where things stand as of October 2026.

Complement inhibitors

Complement is a group of immune proteins. In AChR-positive MG, it helps damage the nerve-muscle connection. These medicines block it.

Eculizumab (Soliris): Approved in 2017 for adults with AChR-positive generalized MG. In 2025, approval expanded to children age 6 and older with AChR-positive generalized MG. Given by IV.
Ravulizumab (Ultomiris): Approved in 2022 for adults with AChR-positive generalized MG. A longer-acting IV medicine, so infusions are spaced further apart.
Zilucoplan (Zilbrysq): Approved in 2023 for adults with AChR-positive generalized MG. A daily shot under the skin that you can give at home.

These medicines raise the risk of serious meningococcal infections. You will need meningococcal vaccines, and sometimes antibiotics, before and during treatment.

FcRn blockers

These medicines help your body clear out IgG antibodies faster, including the ones that cause MG.

Efgartigimod alfa (Vyvgart): Approved in December 2021 for adults with AChR-positive generalized MG. An under-the-skin form, Vyvgart Hytrulo, was approved in 2023. In 2025, the FDA approved Vyvgart Hytrulo for self-injection at home. In May 2026, approval for both forms expanded to all adults with generalized MG, including those who are MuSK-positive, LRP4-positive or seronegative. It is the first FDA-approved treatment for this seronegative group.
Rozanolixizumab (Rystiggo): Approved in 2023 for adults with AChR-positive or MuSK-positive generalized MG. Given as a weekly shot under the skin in cycles.
Nipocalimab (Imaavy): Approved in April 2025 for people age 12 and older with AChR-positive or MuSK-positive generalized MG. Given by IV.

B-cell therapies

B cells are immune cells that grow into the cells that make antibodies.

Inebilizumab (Uplizna): Approved in December 2025 for adults with AChR-positive or MuSK-positive generalized MG. After the first doses, it is given twice a year.
Rituximab (Rituxan): Sometimes used, often when other treatments have not worked. It can have serious side effects.

What is still being studied

Researchers are testing more treatments, including CAR T-cell therapy for hard-to-treat MG. Other new medicines are under FDA review. Ask your neurologist if a clinical trial might be a good fit for you.

Questions to Ask Your Neurologist

What is my antibody type, and which treatments fit it?
What results should I expect, and how soon?
What side effects should I watch for?
Which vaccines do I need before starting?
How will this treatment be given, and how often?
What should I do if my symptoms suddenly get worse?

Call 911 or go to the ER right away if you have trouble breathing, feel short of breath when lying flat, cannot swallow or cannot clear saliva. These can be signs of a myasthenic crisis.

Frequently Asked Questions

What is the first-line treatment for myasthenia gravis?

Many people start with pyridostigmine to ease symptoms. Steroids or other immune medicines are often added to treat the immune attack. Your doctor will build a plan based on your symptoms and antibody type.

Is there a treatment for seronegative myasthenia gravis?

Yes. Standard treatments like pyridostigmine, steroids and immunosuppressants can be used. In May 2026, the FDA expanded the approval of Vyvgart and Vyvgart Hytrulo to include adults with seronegative generalized MG.

Can I stop my MG medicine if I feel better?

Do not stop or lower any MG medicine on your own. Stopping suddenly can make symptoms flare. Some people in remission can reduce medicines, but only with their doctor’s guidance.

Does insurance cover the newer MG drugs?

Coverage varies by plan, and some plans require prior approval. Your neurologist’s office and the drug maker’s patient support program can often help you sort out coverage and costs.

The Bottom Line

Myasthenia gravis treatment often combines pyridostigmine, steroids or other immune medicines and, for some people, thymectomy. IVIG and plasma exchange offer fast, short-term help during flares or a crisis. Since 2017, the FDA has approved several targeted medicines, including complement inhibitors, FcRn blockers and a B-cell therapy. Work with your neurologist to find the plan that fits your antibody type, symptoms and life.
