Terfenadine (Cat.No:I003801) was an antihistamine used to treat allergies and hay fever. Due to its potential to cause cardiac arrhythmias, it was withdrawn from the market in many countries and replaced with fexofenadine. Terfenadine’s metabolite, fexofenadine, is now widely used as a safer alternative for allergy relief.
