Ketotifen is a medication that is primarily used to treat allergic conditions such as asthma, allergic rhinitis (hay fever), and allergic conjunctivitis (eye allergies). It belongs to a class of drugs called antihistamines and mast cell stabilizers. When taken orally, ketotifen works by inhibiting the release of histamine, a chemical substance that is responsible for allergic reactions. By blocking the release of histamine, ketotifen helps to alleviate symptoms associated with allergies, including itching, sneezing, runny nose, and watery eyes. .
