Approaches to Switching Therapies for Patients With MF

When switching JAK inhibitors for myelofibrosis, Aaron Gerds, MD, MS, advises stopping ruxolitinib and starting the new JAK inhibitor the next day due to its short half-life, though tapering ruxolitinib over 1 week is recommended for patients on higher doses to avoid rebound symptoms; pacritinib and fedratinib have longer half-lives so a 1-week washout can be considered.
