Fexofenadine, an antihistamine, can be safely combined with most OTC cold and flu meds, but avoid those containing additional antihistamines to prevent overdose.
No major interactions exist between fexofenadine and standard OTC cold or flu drugs; however, always check labels for duplicative ingredients like antihistamines.
