The typical first-line treatment for moderate to severe allergic conjunctivitis is the use of over-the-counter antihistamine eye drops. These drops are specifically formulated to alleviate the symptoms associated with allergic reactions, such as itching, redness, and excessive tearing. They work by blocking histamine receptors in the eyes, which reduces the allergic response and provides quick relief from symptoms.

Over-the-counter antihistamine eye drops are advantageous for patients because they are readily accessible and offer a targeted approach to treat eye-specific symptoms without the systemic side effects that may accompany oral antihistamines. This makes them particularly effective and suitable for managing allergic conjunctivitis.

In contrast, antihistamine pills may help with broader allergy symptoms but are not ideal for addressing eye-specific issues. Cold compresses can provide temporary relief from discomfort but do not treat the underlying allergic response. Topical corticosteroids might be effective for more severe cases or persistent symptoms, but they are typically not the first-line treatment due to potential side effects and the need for monitoring during use. Hence, over-the-counter antihistamine eye drops are the most appropriate choice for the management of moderate to severe allergic conjunctivitis.
