i got a what was diagnosed as chemical conjunctivitis in my left eye in july. a doctor prescribed me some eye drops. unfortunately i threw out the box and only have the bottle. it says: neomycin and polymyxin b sulfates and hydrocortisone ophthalmic suspension, usp. just recently i got the same symptoms in the same eye and i really don't want to go back to the doctors and have to pay for another visit. i was wondering if it was safe to use the same medicine he prescribed me last time. if it was anything other than my eye i probably wouldn't be asking.
