Alaway Antihistamine Eye Drops, 12-Hr Itchy Eye Relief, 0.34 oz 2-Pack

When allergies make your eyes itch, don't suffer waiting for allergy pills to work. Created by the eye health experts at Bausch + Lomb, prescription-strength Alaway is clinically tested to relieve eye itch. When people prone to allergies contact allergens, their immune systems can overreact. Immune cells called mast cells release histamine, which binds to receptors in tissues, causing them to enlarge or dilate—your body's way of fighting the allergen. For you, it means watery, itchy, irritated eyes. Alaway antihistamine eye drops provide relief within minutes, targeting symptoms at the source and lasting up to 12 hours. The active ingredient, Ketotifen, blocks Histamine (H1) receptors, stabilizes the mast cell membrane, and prevents the accumulation of Eosinophils—relieving eye itch right where it starts. For adults and children 3 years and older. Please read all warnings and directions on the label before use.
