Cetirizine

Alternative Names: Zyrtec

Cetirizine (Zyrtec) is a second-generation oral antihistamine that can help relieve symptoms of Allergic Conjunctivitis. By blocking histamine, it can reduce eye itching, redness, and tearing that occur with seasonal or environmental allergies. While antihistamine eye drops often work faster for eye symptoms, cetirizine is a convenient option when eye irritation occurs along with other allergy symptoms like sneezing or runny nose. It is generally well tolerated, though mild drowsiness can occur in some people.

Cetirizine can help with symptoms of Allergic Conjunctivitis, though it’s usually not as effective eye drops that work directly in the eye. That said, it’s cheap, over-the-counter, and easy to take once a day, so it’s a convenient option for many people. It can also be taken ahead of allergy season to help prevent symptoms, especially if you’re also dealing with sneezing or a runny nose.
