NEOTISON NASAL is a nasal spray containing budesonide, a synthetic corticosteroid with potent anti-inflammatory effects. It is used to treat symptoms of allergic rhinitis (both seasonal and perennial), such as nasal congestion, runny nose, sneezing, and itching. Budesonide works by reducing inflammation in the nasal passages, thereby relieving these allergy symptoms. It is also used to treat nasal polyps in some cases. Regular use as directed is important for optimal benefit, and it typically takes a few days to achieve its full effect. Common side effects are usually mild and localized to the nasal area, such as nasal irritation, dryness, and nosebleeds.
