How often can i take claritin (loratadine)?

Depends, 1 daily: If you are using Claritin for control of allergic nasal and eye symptoms, one tablet a day is all you need. If you are using Claritin for other medical condition such as chronic hives then your allergist may recommend a higher dose such as twice daily or even 3 times daily. If you are using Claritin more than once a day you should be using the medication under direct allergist supervision.
