Lodoxamide Tromethamine Ophthalmic Solution 0.1%: Mast Cell Stabilizer for Allergic Eye Conditions

Alomide Ophthalmic Solution is a topical Antiallergic medication containing Lodoxamide, a potent mast cell stabilizer. While originally approved for human use, it is utilized by veterinarians on an extra-label basis for dogs, cats, and horses to manage severe allergic eye conditions. Unlike standard antihistamines that block histamine after it is released, Lodoxamide works by stabilizing mast cells to prevent the release of histamine and other inflammatory mediators in the first place. This makes it particularly effective for chronic or hypersensitivity-related ocular inflammation, such as allergic conjunctivitis and keratitis.

Prescription Required

Lodoxamide Tromethamine Ophthalmic Solution is a prescription-only medication. A valid prescription from a licensed veterinarian is required for purchase. Professional diagnosis is necessary to ensure the eye condition is allergic in nature rather than infectious (viral or bacterial), as mast cell stabilizers will not treat infections. Veterinary supervision is also required because this medication typically requires a "loading period" of several days to weeks to reach full effectiveness and must be monitored for side effects such as transient stinging or localized irritation.
