I'm a bit confused right now. I recently had a pretty bad asthma attack, and my doctor switched me to this duolin inhaler. Before that, I was using the Rotahaler, mainly because it was cheaper. I'm trying to figure out if the duolin inhaler is actually better for me or if I can just go back to using the Rotahaler like before. Any advice on what I should do?

Duolin inhaler, containing a combination of Levosalbutamol and Ipratropium, is generally considered more effective than Rotahaler (containing only Levosalbutamol) for managing severe asthma symptoms, as it provides both bronchodilation and anti-inflammatory effects, so it's recommended to continue with Duolin inhaler as advised by your doctor.
