Alcarex Eye Drops 5ml is a prescription antihistamine eye drop used to treat allergic conjunctivitis—a common eye allergy condition characterized by redness, itching, tearing, and swelling of the eyes. Alcaftadine is a third-generation antihistamine, known for its dual-action mechanism that not only blocks histamine receptors but also stabilizes mast cells to prevent the release of allergy-triggering chemicals.

Formulated as a once-daily ophthalmic solution, Alcarex Eye Drops 5ml offers 24-hour protection against seasonal and perennial allergens such as pollen, pet dander, mold, and dust mites. It is suitable for both adult and pediatric patients (aged 2 years and above).

This eye drop is clear, colorless to pale yellow, and designed for direct ocular administration. With a rapid onset of action (within minutes), it effectively relieves ocular itching, redness, and irritation, improving comfort and visual clarity.
