Hey all! My Maine coon has had a few eye infection issues in the past. He hasn't had one in awhile but today his eye is all 'gooped' up and puffy (the same symptoms as before) I have some neopolydex ointment that he was prescribed previously for it. It says it "expired" a little over a year ago, so I was wondering if it would be okay to use? I'm sure the potency has decreased, but is there any dangers with using it? Thanks!
