1-2 days: Claritin (loratadine) works quickly, within 1-2 hours but depending on symptoms, may take several days to see a result.

Within 1-2 hrs: Claritin (loratadine) is well-absorbed from the gastrointestinal tract and its effect is often felt within 1-2 hours. Claritin is metabolized in the liver into Desloratadine (the main ingredient in clarinex) which can stay in your system for many hours, allowing these antihistamines to be dosed once daily.
