Fexofenadine is available in India under several brand names, primarily marketed as an antihistamine for allergy relief. These brands often contain fexofenadine hydrochloride as the active pharmaceutical ingredient.

For instance, Allegra is a well-known brand that has been available in the Indian market. Telfast is another prominent brand that provides fexofenadine-based formulations. Fex is also a commonly found brand name for fexofenadine products.
How does fexofenadine work for allergies?
Fexofenadine is a second-generation antihistamine. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms. Histamine is released when the body encounters an allergen, such as pollen or dust mites, leading to symptoms like sneezing, itching, watery eyes, and runny nose. By inhibiting histamine from binding to its receptors, fexofenadine helps to alleviate these discomforts [1].
Are there different strengths of fexofenadine available?
Yes, fexofenadine is typically available in different strengths to suit varying patient needs and physician recommendations. Common dosages include 120 mg and 180 mg tablets. The choice of strength often depends on the severity of the allergy symptoms.
What is the difference between fexofenadine and other antihistamines?
Fexofenadine is classified as a non-sedating antihistamine. Unlike older, first-generation antihistamines (such as diphenhydramine or chlorpheniramine), fexofenadine is less likely to cause drowsiness because it does not cross the blood-brain barrier as readily. This makes it a preferred option for individuals who need allergy relief without experiencing significant sedation. Other second-generation antihistamines include loratadine and cetirizine, which also offer reduced sedative effects compared to their predecessors.
When might a doctor prescribe fexofenadine?
Doctors prescribe fexofenadine for the symptomatic treatment of seasonal allergic rhinitis (hay fever) and chronic idiopathic urticaria (hives). These conditions involve symptoms such as sneezing, itchy or runny nose, itchy or watery eyes, and skin itching and rashes.
