Lastacaft Once Daily Relief delivers prescription-strength ocular antihistamine therapy through 0.25% alcaftadine formulation, providing rapid symptom resolution for allergic conjunctivitis within 2 minutes of instillation. The once-daily dosing regimen achieves sustained 24-hour therapeutic coverage, minimizing histamine-mediated pruritus and ocular irritation triggered by environmental allergens including pollen, animal dander, and ragweed exposure.

Alcaftadine's selective H1-receptor antagonism provides targeted relief without systemic absorption, reducing adverse effects associated with oral antihistamines.
