Patanase is indicated for the treatment of seasonal allergic rhinitis (hay fever) in adults and children ages 6 years and older. It helps relieve nasal symptoms including congestion, sneezing, itching, and rhinorrhea associated with environmental allergens.
Patanase contains olopatadine, an H1-receptor antagonist. It works by blocking histamine, a substance released during allergic reactions that causes allergy symptoms. The medication is applied directly to the nasal passages for localized relief.
Patanase is for nasal use only. Common side effects may include bitter taste, headache, and nasal discomfort. Patients should avoid spraying the medication into the eyes. Effectiveness may vary among individuals, and it is typically used during allergy season or as directed by a healthcare provider.
