Given by subcutaneous (SC) injections once every two weeks, the recommended starting dose is 100mcg, which can be increased in 50mcg increments up to a maximum of 500mcg/dose depending on the patient’s response to treatment. If blood components have stabilized after one year of therapy, treatments may be changed to once every four weeks. Prefilled, one-dose syringes should be kept in the refrigerator and also protected from exposure to light. An exact date has not been announced, but a launch is expected in the coming weeks.
