<s>[INST] My uncle developed Myasthenial Crisis and was treated with IVIg for 5 days and now he is stabilising. We get to understand that the effect of IVIg remains for a specific period only. What would happen when the effect goes off? Will he again get into the crisis state? What are the ways to treat him so that he does not get into crisis again. [/INST] Hi well come to Chat Doctor. Myasthenia graves is thought to be autoimmune diseases. It not curable condition Doctor usually neurologist taking care will prescribe you to take some maintenance dose of Prestige, or neostigmine like preparation for prevention of crisis. Regular follow up with neurologist, and re adjustment of doses as per need will help you to prevent crisis. And adjust lifestyle as per recommendation of neurologist. Thanks </s>
