Flonase is used to treat symptoms of seasonal and year-round allergic rhinitis, including nasal congestion, sneezing, runny nose, and itching. It may also help relieve itchy, watery eyes associated with allergies.
Flonase contains fluticasone, a synthetic corticosteroid that works by reducing inflammation and suppressing immune responses in the nasal passages. This decreases swelling, mucus production, and histamine release that cause allergy symptoms.
Flonase is for nasal use only. It may take several days of consistent use to experience full symptom relief. Common side effects may include nasal irritation, nosebleeds, and headache. Patients should avoid contact with people with chickenpox or measles while using this medication. Consult a doctor before use if pregnant or breastfeeding.
