Fexofenadine: The Complete Guide to Allergy Relief
What is Fexofenadine?
Fexofenadine is a highly effective antihistamine used to relieve symptoms caused by allergies, including hay fever (allergic rhinitis) and chronic hives (urticaria). Commonly known under brand names like Telfast and Allevia, generic Fexofenadine is equally effective but more affordable.
Fexofenadine is a non-drowsy antihistamine, making it a preferred option for those who need allergy relief without the side effects of sleepiness.
How Does Fexofenadine Work?
Fexofenadine blocks the effects of histamine, a chemical released by your immune system during an allergic reaction. By inhibiting histamine, Fexofenadine helps alleviate swelling, congestion, and other allergy-related symptoms.
