Dosing
All indications Initial dose 5-60 mg once daily with food; RAYOS releases active substance approximately 4 hours after intake. Titrate to lowest effective maintenance dose; withdraw gradually after long-term or high-dose therapy.
Immune thrombocytopenic purpura Initial dose 1 mcg/kg SC injection once weekly; adjust by 1 mcg/kg increments based on platelet count; maximum weekly dose 10 mcg/kg.
Hematopoietic subsyndrome of acute radiation syndrome 10 mcg/kg as a single SC injection, administered as soon as possible after suspected or confirmed exposure to myelosuppressive doses of radiation (>2 Gy).
Contraindications
- Known hypersensitivity to prednisone or any excipient

Serious Anaphylaxis, cardiac arrest, circulatory collapse, congestive heart failure, myocardial rupture, pulmonary edema, peptic ulcer with perforation and hemorrhage, osteonecrosis, pathologic fracture, adrenocortical insufficiency, convulsions, increased intracranial pressure
Postmarketing No new safety concerns identified beyond those established for immediate-release prednisone
Most common (>=5%) Arthralgia, myalgia, pain in extremity, shoulder pain, dizziness, paresthesia, insomnia, abdominal pain, dyspepsia (adults); contusion, upper respiratory tract infection, oropharyngeal pain, pyrexia, rash, diarrhea (pediatric)

Postmarketing Erythromelalgia, hypersensitivity reactions including angioedema and anaphylaxis
Pharmacology
Prednisone is a synthetic corticosteroid with potent anti-inflammatory and immunosuppressive properties that suppresses inflammatory processes (edema, capillary dilatation, leukocyte migration), modifies immune responses, and produces metabolic effects including promotion of gluconeogenesis, protein catabolism, and altered calcium and electrolyte balance.
Thrombopoietin receptor agonist; Fc-peptide fusion protein (peptibody) that binds and activates the TPO receptor to increase platelet production through a mechanism analogous to endogenous TPO.
