Pataday for Allergies
Pataday™ (olopatadine ophthalmic solution) is a prescription eyedrop that belongs to a class of medications known as antihistamines. Healthcare providers often recommend Pataday for allergies, specifically for the treatment of itchy eyes due to allergic conjunctivitis.
The medication works by blocking a specific type of histamine receptor in the body (known as H1 receptors). It also appears to decrease the release of histamine from cells in the body. Since the symptoms of allergic reactions are partly caused by histamine, Pataday can help prevent or relieve allergy symptoms.
Even though most people have no problems with Pataday, as with any medication, side effects are possible. Some of the most common side effects that have been reported with this eyedrop include sore throat, burning or stinging, and symptoms of the common cold.
