Treatment choice depends on the severity of symptoms

Myasthenia gravis.

Treatment choice depends on the severity of symptoms.

In mild disease such as in this case, acetylcholinesterase inhibitors such as pyridostigmine are useful in control of symptoms. In more severe disease, with limb weakness or bulbar dysfunction immunomodulatory agents are often required. Steroids are often employed, with the addition of steroid-sparing agents such as mycophenolate mofetil, ciclosporin or azathioprine if necessary.

Intravenous immunoglobulin and plasma exchange are useful in myasthenic crises. Thymectomy improves symptoms in cases associated with thymoma, and may also be beneficial in young patients with recent onset of symptoms, but would not be used as an initial treatment option.
