Medications for myasthenia gravis are used to treat this condition. These medications may also have other uses. They work by improving the nerve signal transmission to muscles or by modulating the immune system. Common classes include cholinesterase inhibitors and monoclonal antibodies. Cholinesterase inhibitors like pyridostigmine (Mestinon) are usually taken as oral pills. Monoclonal antibodies, such as Vyvgart (efgartigimod alfa) and Rystiggo (rozanolixizumab), are typically given as injections. These options provide different ways to help manage your symptoms effectively.
