I use a ventoline inhaler occassionally. I have a bad case of bronchitus right now as was diagnosed by the DOC at the local hospital last night. He gave me a script for a new inhaler but out drugstores were closed today. My old inhalers expiry date is Sept 2013, is it still okay to use?
Hi and welcome to Chat Doctor, It is not advisable.  It is harmful.  Use new inhaler.  Activity of the medicine will be low and not good to use.  It may lead other complications.  Thanks
