I honestly wouldn't see why not. Ventolin (or salbutamol - as is its active ingredient) has few side effects, compared to its 50s and 60s equivalents like Theophylline - [which can lead to heart attacks and is pretty much banned, apart from serious prescriptive need].
It (salbutamol) is strictly monitored in many countries, such as UK and USA/Australia. But in others, you can buy it over the counter, like Spain and Greece. I think physicians monitor carefully, as overuse can be masking more serious lung conditions. If you self medicate, and buy over the counter, you could be treating the symptoms of COPD, certain cancers and emphysema. And, thus, your doctor wouldn't know a thing about it, as salbutamol often automatically eases the lining of the lung, whatever the root cause!
I am asthmatic, drink vodka relatively regularly, and use Salbutamol (probably too often really - as am stupidly a smoker). I'm not a GP and obviously don't speak for everyone. If you are overly concerned, ask a pharmacist, but I would be surprised if Salbutamol monkeyed around with alcohol effects. Although, I understand it CAN add to anxiety symptoms, which can be provoked by alcohol consumption.
Hope that helps.
