What is a common first-line treatment for allergic conjunctivitis?

A common first-line treatment for allergic conjunctivitis is the use of antihistamine eye drops. Allergic conjunctivitis occurs when the eyes become inflamed due to allergens such as pollen, dust, or pet dander, triggering an immune response in the body. Antihistamine eye drops specifically target the histamine receptors in the eyes, helping to alleviate symptoms such as itching, redness, and tearing associated with allergic reactions.

These types of eye drops act quickly to reduce the symptoms of inflammation and itching caused by allergens, providing much-needed relief for patients. Additionally, antihistamine eye drops can prevent the onset of severe allergic reactions when used proactively in seasons or environments known to provoke allergies.

In contrast, while oral steroids may be used in more severe allergic reactions or if the condition doesn’t respond to other treatments, they are not considered a first-line option due to their potential side effects. Antibiotic eye drops are more appropriate for bacterial conjunctivitis rather than for allergic conjunctivitis, which is not caused by bacteria. Artificial tears can provide temporary relief by lubricating the eyes, but they do not specifically address the underlying allergic response that antihistamine drops do.
