  * is postmenopausal for at least 1 year; or
  * is surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy).

Exclusion Criteria:

* Volunteers with a recent history of drug or alcohol addiction or abuse.
* Volunteers with the presence of a clinically significant disorder involving the cardiovascular, respiratory, renal, gastrointestinal, immunologic, hematologic, endocrine, or neurologic system(s) or psychiatric disease (as determined by the clinical investigators).
* Volunteers whose clinical laboratory test values are outside the accepted reference range and when confirmed on re-examination are deemed to be clinically significant.
* Volunteers demonstration a positive hepatitis B surface antigen screen, hepatitis C antibody screen or a reactive HIV antibody screen.
* Volunteers demonstrating a positive drug abuse screen when screened for this study.
* Female volunteers who are currently breast feeding.
* Female volunteers who are demonstrating a positive pregnancy screen.
* Volunteers with a history of allergic response(s) to fexofenadine or related drugs.

* Volunteers who have taken any drug known to induce or inhibit hepatic drug metabolism in the 30 days prior to Period I dosing.
* Volunteers who report donating greater than 150 mL of blood within 30 days prior to Period I dosing. All subjects will by advised not to donate blood for four weeks after completing the study.
* Volunteers who have donated plasma (e.g. plasmapheresis) within 14 days prior to Period I dosing. All subjects will be advised not to donate plasma for four weeks after completing the study.
* Volunteers who report receiving any investigational drug within 30 days prior to Period I dosing.
* Volunteers who report taking any prescription medication in the 14 days prior to Period I dosing, with the exception of topical products without systemic absorption.
* Volunteers who have been on an abnormal diet during the 28 days prior to Period I dosing.
* Volunteers who report an intolerance of direct venipuncture.
