Allegra (fexofenadine) d and levocetrizine taken together, safe ?

Allergy: Both medications has been used for allergy symptoms. I do not recommend to take it together if your allergy symptoms is not under controlled you can ask your physician to add another kind of medication to your current medication.

Bit much: its a fair amount of antihistamine taken at the same time since they both do the same thing trick with allergy meds is to take them between 4 and 6 pm and the d is sedated which would keep you awake anyway
