Mechanisms compared
Tadalafil: The mechanism is identical to original Cialis: tadalafil selectively inhibits PDE5 in penile and vascular smooth muscle, allowing cyclic GMP produced during sexual arousal to accumulate. Fexofenadine: Fexofenadine selectively blocks peripheral H1 histamine receptors, antagonising the effects of histamine on vasodilation, capillary permeability, sensory nerve endings and smooth muscle.

Comparing Tadalafil with Fexofenadine makes sense when both are in the same clinical decision: the prescriber has weighed both for different but related conditions. If the question is between two options for the same need, the prescriber decides based on prior response, comorbidities and tolerance.
