Key takeaways
Bronchitol (mannitol) and dexamethasone are both prescription medications, but they serve different purposes and belong to different drug classes. Bronchitol (mannitol) is a mucolytic agent used to improve lung function in adults with cystic fibrosis (CF) by thinning mucus, making it easier to cough out. It is inhaled twice a day using a special inhaler. On the other hand, dexamethasone is a corticosteroid that treats a wide range of inflammatory conditions, including allergies, autoimmune diseases, and certain cancers. It can be taken orally or via injection. Unlike Bronchitol, dexamethasone has a generic form and is known for its long-lasting effects. While Bronchitol requires a tolerance test before use due to the risk of bronchospasm, dexamethasone has a broader range of side effects, including weight gain and weakened bones, especially with long-term use. Additionally, dexamethasone interacts with many other medications, so you need to inform your healthcare provider about all the drugs you are taking.
