Ketotifen

Ketotifen fumarate (ophthalmic solutions marketed under the brand name Zaditor (Novartis) and Alaway (Bausch and Lomb)) is an H1-antihistamine/mast cell stabilizer available in two forms. In its ophthalmic form, it is used to treat allergic conjunctivitis, or the itchy red eyes caused by allergies. In its oral form, it is used to prevent asthma attacks. Side effects include drowsiness, weight gain, dry mouth, irritability, and increased nosebleeds.

General Information
Ketotifen relieves and prevents eye itchiness and/or irritation associated with most seasonal allergies. It starts working within minutes after administering the drops. The drug has not been studied in children under 3.

Overdosage
Accidental ingestion of an entire bottle of ketotifen is unlikely to cause side effects since it contains less than 2 mg of medicine.
