Key takeaways
Flunisolide and Pulmicort Flexhaler (budesonide) are both corticosteroids, but they are used for different conditions and administered differently. Flunisolide is a nasal spray used to treat nasal symptoms caused by seasonal or year-round allergies, while Pulmicort Flexhaler is an inhaler used to control and prevent asthma symptoms. Flunisolide is sprayed directly into the nose to reduce inflammation and relieve nasal symptoms, whereas Pulmicort Flexhaler is inhaled into the lungs to lower inflammation and prevent asthma attacks. Flunisolide is available as a lower-cost generic, while Pulmicort Flexhaler is also available in a generic form. Both medications can be used in children as young as 6 years old. Common side effects of flunisolide include nasal burning and stinging, while Pulmicort Flexhaler can cause cold-like symptoms and fungal infections in the mouth and throat. Both medications require consistent daily use for the best results, but Pulmicort Flexhaler is not a rescue inhaler and won't help during an asthma attack.
