From the Guidelines
The most effective treatment for allergic conjunctivitis is a combination of allergen avoidance and medication, with antihistamine eye drops such as olopatadine (Patanol), ketotifen (Zaditor), or azelastine (Optivar) being first-line treatments, used 1-2 drops in each affected eye twice daily, as recommended by the most recent study 1. The treatment of allergic conjunctivitis involves a multi-faceted approach, including:
- Allergen avoidance: wearing sunglasses, cold compresses, refrigerated artificial tears, avoiding eye rubbing, and avoiding allergens 1
- Medication:
- Antihistamine eye drops: olopatadine (Patanol), ketotifen (Zaditor), or azelastine (Optivar) used 1-2 drops in each affected eye twice daily 1
- Mast cell stabilizers: cromolyn sodium (Crolom) used 1-2 drops 4-6 times daily for prevention 1
- Topical corticosteroids: loteprednol (Alrex) or fluorometholone (FML) may be prescribed short-term (typically 1-2 weeks) to reduce inflammation 1
- Oral antihistamines: cetirizine (10mg daily) or loratadine (10mg daily) can supplement topical therapy for systemic relief 1
- Symptomatic relief: cold compresses applied to closed eyes for 5-10 minutes several times daily, and artificial tears used 4-6 times daily to flush allergens and provide lubrication 1 It is essential to note that the treatment should be tailored to the individual patient's needs, and the most recent and highest-quality study should be consulted for the most up-to-date recommendations 1.
From the FDA Drug Label

From the Research
Treatment Options for Allergic Conjunctivitis
The recommended treatment for allergic conjunctivitis includes:
- Topical antihistamines
- Mast cell stabilizers
- Dual-action agents
Topical Antihistamines and Mast Cell Stabilizers
Studies have shown that topical antihistamines and mast cell stabilizers are effective in treating allergic conjunctivitis 3, 4, 5, 6. These medications can provide quick relief from symptoms such as itching, redness, and tearing.
Dual-Action Agents
Dual-action agents, such as olopatadine and ketotifen, have been shown to be effective in treating allergic conjunctivitis 3, 4, 6, 7. These agents have both antihistamine and mast cell stabilizing properties, making them a popular choice for treating mild forms of allergic conjunctivitis.
Comparison of Treatments
Studies have compared the efficacy of different treatments for allergic conjunctivitis, including olopatadine and ketotifen 3, 4, 6. The results have shown that olopatadine is often more effective than ketotifen in reducing symptoms of allergic conjunctivitis.
Key Findings
- Olopatadine has been shown to be more effective than ketotifen in reducing symptoms of allergic conjunctivitis 3, 4.
- Dual-action agents, such as olopatadine and ketotifen, are effective in treating mild forms of allergic conjunctivitis 5, 6, 7.
- Topical antihistamines and mast cell stabilizers can provide quick relief from symptoms of allergic conjunctivitis 3, 4, 5, 6.
