Olopatadine is prescribed to treat symptoms caused by allergic reactions. Ophthalmic olopatadine (eye drops) are prescribed to reduce itching, redness, and discomfort caused by allergic conjunctivitis. As a nasal spray, olopatadine reduces runny nose symptoms as well as itching and sneezing.
Allergic reactions happen when your body thinks that harmless substances, like pet dander or peanuts, are actually pathogens that could make you sick. When this happens, your body prompts an immune response - which causes the symptoms like itchy eyes, itchy or runny nose, and scratchy throat that make allergic reactions troublesome.
Seasonal allergy symptoms can include allergic rhinitis (sneezing, runny nose, itchy nose, sinus pressure or pain, nasal congestion), and swollen or red itchy eyes. There is no cure for allergies, but the symptoms listed above can be managed with a treatment plan.
