Health & WellnessCan I use old Tobramycin eye drops for my dog's green eye discharge?
If it is just a little bit of discharge, then I would continue to monitor it. Tobramycin is an antibiotic, and if it was prescribed for Jackie, it should be safe. But you don't want to accidentally treat a bacterial infection when the true cause of the discharge is something like a corneal ulcer. Applying this medication before a vet makes a diagnosis may make it harder for the vet to determine the cause of the issue, if needed. Use a warm wet washcloth to remove the discharge. If it continues in a couple of hours, I would recommend that you call the vet that prescribes the medication to see if they recommend an exam or that you use the ointment.
