Terminal elimination half-life is 12-15 hours. Clinical context: Allows for twice-daily dosing in allergic rhinitis; steady-state reached in 2-3 days.
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.
