Flonasin is a metered-dose nasal spray that combines two active ingredients: Azelastine Hydrochloride (137 mcg) and Fluticasone Propionate (50 mcg). Azelastine is an antihistamine that helps block histamine receptors, reducing common allergy symptoms like sneezing, runny or itchy nose, and nasal congestion. Fluticasone is a corticosteroid that reduces inflammation in the nasal passages, providing additional relief. This dual-action formulation is primarily used to treat seasonal allergic rhinitis in adults and children over 6 years old. The recommended dosage is typically one spray in each nostril once or twice daily, depending on the instructions of a healthcare provider. Common side effects include nasal irritation, headache, dry mouth, and an unpleasant taste. It is important to shake the bottle before use and prime the spray if it hasn’t been used for a while. Flonasin is available in 120-metered sprays and can be purchased at pharmacies, mostly in Bangladesh.
