instruction: hi firstly I would like to thank for this wonderful and a very helpful service of online consultation my query is I have been using inhaler cipla serflo 250 from almost years as I am an asthma patient as its a hereditary thing that I have but as I am in a foreign country at the moment and my inhaler is about to get over and due to this pandemic time I cannot get it imported to my place but I have a friend who has given me maxiflow 250 from cipla as well so I wanted to know if I can use that as an alternative inhaler as I do not have my serflow 250 inhaler in stock your assistance would be highly appreciated and much obliged thank you
