Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Acetylcholinesterase inhibitors
Symptomatic treatment that increases acetylcholine at the neuromuscular junction by inhibiting the enzyme that breaks it down, providing temporary improvement in muscle strength and fatigue.
Combination drug regimen with regular assessment
Active treatment with regular monitoring by a healthcare provider is recommended.
Immunosuppressive therapy
Long-term immunomodulatory treatment using agents such as corticosteroids, azathioprine, or mycophenolate to suppress antibody-mediated destruction of acetylcholine receptors.
Additional treatment options
Plasma exchange
Removal of pathogenic antibodies from the blood through filtration or centrifugation, providing rapid improvement in severe or myasthenic crisis situations.
procedureThymectomy
Surgical removal of the thymus gland, which may reduce symptoms and allow for medication reduction in patients with thymoma or generalized MG without thymoma.
surgicalEnergy conservation techniques
Structured approach to daily activities using pacing strategies, adaptive equipment, and planned rest periods to minimize muscle fatigue and prevent symptom exacerbation.
