Fexofenadine hydrochloride.

Works by

Fexofenadine functions by blocking the actions of histamine, a naturally occurring substance in the body and found in various foods. When the immune system detects foreign substances like pollen or dust, it releases histamine as a defense mechanism, leading to cellular expansion and swelling. However, this swelling triggers inflammation, causing symptoms such as congestion and hay fever. By inhibiting the effects of histamine, fexofenadine alleviates discomfort induced by pollen or other allergens.

Side effects

Drowsiness, nausea, and dizziness.
