Side effects needing medical attention after stopping this medication
Following interruption or discontinuation of ruxolitinib, symptoms of myelofibrosis generally return to pretreatment levels over a period of approximately 1 week. There have been isolated cases of patients discontinuing Jakafi during acute intervening illnesses, after which the patient's clinical course continued to worsen. It has not been established whether discontinuation of therapy contributed to the clinical course in these patients. When discontinuing therapy for reasons other than thrombocytopenia, gradual tapering of the dose of Jakafi may be considered.
