Fexofenadine FAQs
What is Fexofenadine?
Fexofenadine is an antihistamine used to treat allergy symptoms, such as hay fever (allergic rhinitis) and hives (urticaria). It works by blocking histamine, a substance in the body that causes allergic reactions like itching, sneezing, runny nose, and watery eyes. Unlike older antihistamines, Fexofenadine is less likely to cause drowsiness. It is available in tablet, capsule, and oral suspension forms.
What are Fexofenadine tablets used for?
Fexofenadine tablets are mainly used to relieve allergy symptoms, including:
- Hay fever (allergic rhinitis): Symptoms like sneezing, itchy or runny nose, nasal congestion, and itchy or watery eyes due to allergens such as pollen, dust, or pet dander.
- Hives (urticaria): Itchy, raised welts on the skin triggered by allergens like certain foods, medications, or environmental factors.
Fexofenadine works by blocking histamine, which reduces symptoms such as sneezing, itching, runny nose, and watery eyes.
