F-ZONE by Chemisis Pharmaceuticals contains Fluticasone, a corticosteroid used to manage and relieve symptoms of allergic rhinitis, such as nasal congestion, sneezing, and runny or itchy nose. Fluticasone works by reducing inflammation in the nasal passages, thereby helping to alleviate symptoms caused by seasonal or perennial allergies. The typical dosage of F-ZONE is one or two sprays in each nostril once daily, preferably in the morning. For best results, it should be used regularly at the same time each day. It is important to follow the prescribed dosage and not to exceed the recommended amount. Before using the nasal spray, patients should gently blow their nose to clear the nostrils. After administering the spray, it is advisable to avoid blowing the nose for at least a few minutes to ensure the medication is adequately absorbed. Common side effects may include nasal dryness or irritation, sore throat, nosebleeds, and headache. Serious side effects are rare but can include severe allergic reactions, vision problems, and infections. Patients should consult a healthcare provider if they experience any persistent or severe side effects.
