Ketotifen (Zaditor) is a relatively selective, noncompetitive H₁-receptor antagonist and mast cell stabilizer that relieves symptoms of allergic conjunctivitis for up to 12 hours. It has been available by prescription and OTC since 2006. The usual dose is one drop in the affected eye every 8 to 12 hours. The other ophthalmic antihistamines require a prescription.
