Interactions
7 DRUG INTERACTIONS Closely monitor for reduced effectiveness of medications that bind to the human neonatal Fc receptor. When concomitant long-term use of such medications is essential for patient care, consider discontinuing RYSTIGGO and using alternate therapies. ( 7.1 ) 7.1 Effect of RYSTIGGO on Other Drugs Concomitant use of RYSTIGGO with medications that bind to the human neonatal Fc receptor (FcRn) (e.g., immunoglobulin products, monoclonal antibodies, or antibody derivatives containing the human Fc domain of the IgG subclass) may lower systemic exposures and reduce effectiveness of such medications. Closely monitor for reduced effectiveness of medications that bind to the human neonatal Fc receptor.
Warnings
5 WARNINGS AND PRECAUTIONS Infections: Delay administration of RYSTIGGO to patients with an active infection. Monitor for signs and symptoms of infection in patients treated with RYSTIGGO. If serious infection occurs, administer appropriate treatment and consider withholding RYSTIGGO until the infection has resolved. ( 5.1 ) Aseptic Meningitis: Serious events of aseptic meningitis have been reported. Monitor for symptoms; diagnostic workup and treatment should be initiated according to the standard of care. ( 5.2 ) Hypersensitivity Reactions: Angioedema and rash have occurred. If a hypersensitivity reaction occurs, discontinue the infusion and institute appropriate therapy. ( 5.3 ) 5.1 Infections RYSTIGGO may increase the risk of infection [see Adverse Reactions (6.1) ] . 4 CONTRAINDICATIONS None. None. ( 4 )
