Häufig gestellte Fragen
Is Fexofenadine better than Trazodone? ▾
Fexofenadine and Trazodone are not "better or worse" — they treat different things. The sensible question is which fits your specific need.
Can Fexofenadine and Trazodone be combined? ▾
Whether they can be combined depends on the indications and the interaction profile of each. If both are in a single prescription, the prescriber has weighed it; in self-medication they should never be combined.

No — they belong to different classes and have distinct side-effect profiles. Each has its own prescribing information.
