===Mast cell stabilizers===
[[Mast cell]] stabilizers can help people with allergic conjunctivitis. They tend to have delayed results, but they have fewer side-effects than the other treatments and last much longer than those of [[antihistamines]]. Some people are given an antihistamine at the same time so that there is some relief of symptoms before the mast cell stabilizers becomes effective. Doctors commonly prescribe [[lodoxamide]] and [[nedocromil]] as mast cell stabilizers, which come as eye drops.{{cn|date=July 2022}}

A mast cell stabilizer is a class of non-steroid controller medicine that reduces the release of inflammation-causing chemicals from mast cells. They block a calcium channel essential for mast cell degranulation, stabilizing the cell, thus preventing the release of [[histamine]]. Decongestants may also be prescribed. Another common mast cell stabilizer that is used for treating allergic conjunctivitis is [[sodium cromoglicate]].
