Management principles:

  • avoidance of allergen if known

  • topical antihistamines may be useful, oral antihistamines do not have a role (1)
    • eye drops of antihistamines such antazoline (with xylometazoline as Otrivine-Antistin®), azelastine, epinastine, ketotifen and olopatadine may be used for allergic conjunctivitis
    • not a therapeutic option that is appropriate for prolonged use (no longer than six weeks)
    • not an appropriate treatment option in contact dermatoconjunctivitis

  • oral antihistamines such as loratadine or chlorphenamine may be used
    • especially useful when there is associated allergic rhinitis
    • can cause drowsiness, especially the older compounds such as chlorphenamine - patients need to be cautioned regarding this

  • other possible preparations include:
    • sodium cromoglicate (sodium cromoglycate) and nedocromil sodium eye drops - these preparations can be useful for vernal keratoconjunctivitis and other allergic forms of conjunctivitis
    • lodoxamide eye drops - this preparation may be used for allergic conjunctival conditions including seasonal allergic conjunctivitis
    • diclofenac eye drops and emedastine eye drops are also licensed for seasonal allergic conjunctivitis

  • in general, corticosteroid containing ointments or drops should be avoided unless the prescriber is able to monitor accurately for adverse effects (1) e.g. glaucoma, cataract - only used where there is no doubt about the diagnosis

  • oral corticosteroid therapy
    • a short (five-day) course may be used in severe cases where there is no doubt about the diagnosis
    • ophthalmologists may use oral steroids in severe cases of allergic conjunctivitis
