Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
Terminal elimination half-life: 20-25 hours (range 14-36 hours). Clinical context: Supports once-daily dosing for chronic allergic symptoms; accumulation possible with hepatic impairment.
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
