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.
Asthma 75 to 375 mg SC every 2 or 4 weeks based on serum total IgE level (IU/mL) measured before the start of treatment and body weight (kg).
Chronic rhinosinusitis with multiple nasal polyps 75 to 600 mg SC every 2 or 4 weeks based on serum total IgE level (IU/mL) measured before the start of treatment and body weight (kg).
IgE-mediated food allergy 75 to 600 mg SC every 2 or 4 weeks based on serum total IgE level (IU/mL) measured before the start of treatment and body weight (kg).
Chronic Spontaneous Urticaria 150 or 300 mg SC every 4 weeks; dosing is not dependent on serum IgE level or body weight.
Contraindications
- Known hypersensitivity to prednisone or any excipient
- Severe hypersensitivity reaction to omalizumab or any ingredient of XOLAIR

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.
Omalizumab is a recombinant humanized IgG1 monoclonal antibody that inhibits the binding of IgE to high-affinity IgE receptors (FceRI) on mast cells, basophils, and dendritic cells, resulting in FceRI down-regulation and reduction of IgE-mediated inflammatory responses; in CSU, omalizumab binds to IgE and lowers free IgE levels with down-regulation of IgE receptors, though the exact mechanism by which this results in CSU symptom improvement is unknown.
