What Is Claritin Eye?

Claritin® Eye (ketotifen ophthalmic solution) is a nonprescription eye drop approved to temporarily relieve eye itching due to allergies. Specifically, it is approved to treat eye allergies (known medically as allergic conjunctivitis) due to pollen, ragweed, animal hair, grass, and dander.

How Does Claritin Eye Work?

The active ingredient of Claritin Eye is ketotifen. Ketotifen is an H1 receptor antagonist, commonly known as an antihistamine. It blocks a specific type of histamine receptor in the body known as H1 receptors. Since the symptoms of allergic reactions are partly caused by histamine, Claritin Eye can help prevent or relieve allergy symptoms.
The active ingredient of Claritin Eye is different from loratadine, the active ingredient in other Claritin products.
