Fexofenadine is rapidly absorbed after oral administration with peak plasma concentration being reached in 2-3 hours. Elimination half-life of about 14 hours has been reported although this may be prolonged in patients with renal impairment.
Dosage & Administration
- Allergic rhinitis: 120 mg once daily or 60 mg twice daily
