The website for Ventolin talks about a metered dose inhaler, so there is one available. Whether you want to pay for the counter is really the issue.....

In the US, the brand-name Ventolin (and some generics) have a built in dose counter to monitor usage. In addition, the inhalers brands Advair and Flovent include counters as well. There are also Digital counters which work with other general and specific dispensers for the common medications we use. See here:
