I'm using it right now and have been for about 2weeks and am starting to see an improvement. Yes, it has Tylosin in it which is an antibiotic. I am going to use it until the tearing and staining clears up and then will stop. I hope it works b/c I've tried everything from ACV, to reg vinegar, to distilled water etc. I think I am going to try the distilled water in conjunction to the Angel Eyes to hopefully boost effects.
Good Luck, I've been dealing with eye gunk since the day Snickers came home to us.....not fun
