The staff must have not been trained very well. I received an expired sample from the doctor. The sample required long term refrigeration as well. A couple days after receiving it, and after talking to the manufacturer, I called the office and asked a clerk about it. She told me all eye drops are okay to use past their expiration date and that Azasite does not need to be refrigerated during storage. Do not use this dr's office. They do not respect these medications. I am a pharmacist.
