Yes, you can generally take Allegra (fexofenadine) before a colonoscopy, as it is an antihistamine used for allergy relief and does not interfere with the procedure. However, it's essential to consult your healthcare provider or the medical team performing the colonoscopy for specific guidelines, as they may have particular instructions based on your health history or the sedation used during the procedure.
