Flunisolide (flunisolide) — Uses, Dosage, Side Effects & Safety

Drug class: Corticosteroid (Inhaled/Nasal)

Overview

Flunisolide is a corticosteroid medication used to treat symptoms of allergic rhinitis (such as sneezing, runny or stuffy nose) and to manage asthma when delivered via inhalation. It works by reducing inflammation in the nasal passages or airways, helping to relieve symptoms and improve breathing. Flunisolide is not a rescue medication and will not provide immediate relief of acute asthma attacks. It is intended for regular use as prescribed by your healthcare provider to control chronic symptoms. Patients should use it consistently for best results and follow all instructions regarding administration. Key points: Flunisolide may take several days to reach full effect. Rinse your mouth after inhalation to reduce the risk of oral thrush. Do not stop using Flunisolide abruptly without consulting your doctor.
